Laurence,<br />
<br />
ローレンス, <br />
<br />
Checking dpreview after hearing the news, I was amused to see that not much has changed in recent years.<br />
<br />
発表のニュースを聞いた後dpreviewをチェックし, Quattro センサーはここ数年であまり大きく変化していないのだと分かってなんだか愉快な気持になってしまった. <br />
<br />
Your Shakespearean description is not bad. The collected electrons are exactly the corpses of absorbed photons, which is the point that most people who talk about the filtering miss: absorption and filtering and detection being the same event.<br />
<br />
君のシェイクスピア風の記述はイイね. 集められた電子は確かに, 吸収された光子の成れの果てというところだ. これが多くの人たちが話題にしている"filtering miss"についてのポイント: 吸収とフィルタリングと検知は全て同じ事象である, だ. <br />
<br />
But the "stronger" and "weaker" is not quite right. The high-frequency blue photons are stronger (highest energy); but the way they interact with silicon makes them get absorbed soonest, near the surface. The lowest energy photons, in the infrared, penetrate deep. Low frequencies, at wavelengths greater than 1100 nm, where the photons are quite weak, are not able to kick electrons out of the silicon lattice at all, so the silicon is completely transparent to them. In between, there's a nicely graded rate of absorption.<br />
<br />
しかし"stronger"(強力)と"weaker"(微弱)という説明は全く正しくない. 高周波数の青光子は"より強い(stronger)" (最も高いエネルギーを持つ); しかしシリコンと接触すると, 青光子が最も早い段階, つまり表面近くで吸収される. 最も低いエネルギーしか持たない光子, つまり赤外光はシリコン内部に深く入り込む. 波長1100nm以上の低周波数帯では光子の力はきわめて弱く, シリコン格子から電子をはじき出すことは全く出来ない. それ故シリコンはそれらに対して完全に透過的だ. その中間帯での吸収率はなめらかで段階的なものになっている. <br />
<br />
Understanding the spectral responses of the layers starts with understanding that at any wavelength, the light intensity decreases exponentially with depth in the silicon. I think I've written about this some place... Anyway, the top layer is not white, not luminance, not blue, but a sort of panchromatic blueish that turns out to work well enough for getting a high-frequency luminance signal. We did a lot of experiments and amazed ourselves how "well enough" the 1:1:4 worked; it was not obviously going to be a good thing, but turned out awesome.<br />
<br />
各レイヤのスペクトル応答性(spectral responses)を知ることは, つまり次のことを理解することから始まる. どの周波数においても光度(light intensity)は, シリコン中の深度に対し指数的に減衰する. たぶんどこかでこのことについて書いたと思うんだけど... ともかく, トップレイヤーは白色ではない, Luminance (輝度)ではない, 青色ではない, なんというかある種の青みががったパンクロマティックで, こいつは高周波数のLuminance信号を取るのに十分だという結果が得られた. 僕たちは数多くの実験を行い, 1:1:4構造がこんなにもうまく動作することに驚かされた; 1:1:4というアイデアは最初から良い結果が得られるだろうと思えるものではなかったんだ. けど結果的には, スンバらしいということが分かった. <br />
<br />
We had 1:1:4 sensors working, including very efficient and effective hardware and software processing pipelines, before I left Foveon back in '06, but the sensors didn't yet have the low-noise fully-depleted top-layer photodiodes of the "Merrill" cameras, and we were only targeting these for cell phones at the time. I expect it will be a killer combination: fully-depleted blue plus 1:1:4. I don't think the red and green are fully depleted, too; that was thought to be somewhere between hard and impossible, which is why they don't have the same low read noise, and one reason why aggregating red and green quads this way is a big win.<br />
<br />
僕たちは1:1:4センサーを実稼動させた. これは非常に効率の良いハードウエアとソフトウエアの演算パイプラインを含む. 僕が'06にFoveonを去る前の話だ. でもこの時点でセンサーはまだ, "Merrill"カメラのような, 低ノイズの完全空乏型(fully-depleted) フォトダイオードをトップレイヤーに搭載していなかった. また僕らは当時携帯電話のみをターゲットとしていた. 僕はこれはキラー・コンビネーションになると思う: '完全空乏型青 + 1:1:4'. 僕は緑と赤も同じように完全空乏になるとは考えていない; 難しいと不可能の間, といったところだろう. そしてこのことが, ミドル・ボトムレイヤーではトップレイヤーと同程度の低い読み込みノイズは得られない理由であり, また赤および緑を4個1セットに結合させることがこの場合非常に大きな利益をもたらすとする根拠でもある. <br />
<br />
But understanding how it compares to the classic Foveon and to Bayer will keep many people busy for a long time. Something for dpreviewers to do while waiting for cameras, and something to keep the marketing people tied up... Should be fun.<br />
<br />
しかしどのようにして1:1:4構造のセンサーを既存のFoveonセンサーと, またベイヤーと比較できるのかが分かるまで, 長い間多くの人を多忙にさせそうだ. カメラが発売されるのを待つしばしの間, dpreviewerではアンナコト, またマーケティングの人たちをかかりっきりにするソンナコト, 色々あることだろう. 楽しそうじゃないか. <br />

Kendall, long time...<br />
<br />
Kendall, 久しぶり...<br />
<br />
You're right that there won't be much aliasing. A lot of people seem to have the idea that aliasing has something to do with different sampling positions or density, as in Bayer. But that's not the key issue. The problem with Bayer is that the red plane (for example) can never have more than 25% effective fill factor, because the sampling aperture is only half the size, in each direction, of the sample spacing. If you take the Fourier transform of that half-size aperture, you'll find it doesn't do much smoothing, so the response is still quite too high way past the Nyquist frequency. That's why it needs an anti-aliasing filter to do extra blurring. But if the AA filter is strong enough to remove all the aliasing in red, it also throws away the extra resolution that having twice as many green samples is supposed to give. It's a tough tradeoff.<br />
<br />
深刻なエイリアシングは起きないだろうという君の意見は正しい. ベイヤーのように, 異なるサンプリング位置と密度がエイリアシングと関連性を持つ, そう多くの人が考えているようだ. しかしそれは懸念事項ではない. ベイヤーの問題は, (例えば)赤プレーンは絶対に25%以上の実効フィル・ファクター(曲線因子, effective fill-factor)を得ることはできない, なぜならサンプリング径(sampling aperture)はいずれの次元においても, サンプル間隔のたった半分のサイズだから, ということだ. もしそのハーフサイズ径でフーリエ変換を施しても, あまり良くスムージング(smoothing)しないことが分かる. だから得られた結果はナイキスト周波数の高い方に行過ぎてしまっている. 結果更にボカシを入れるためアンチ・エイリアシング・フィルターが必要になるのだ. しかしもしもAA (アンチエイリアシング)フィルターが, 赤での全エイリアシングを除去するのに十分強力であったとすると, 更に解像度を犠牲にすることになる. これは緑サンプルが提供する解像度の2倍であったものだ. 厳しいトレードオフだと思う. <br />
<br />
In the Foveon sensor, the reason no AA filter is needed is not because of where the samples are, or what the different spatial sampling densities are. It's because each sample is through an aperture of nearly 100% fill factor, that is, as wide each way as the sample pitch. The Fourier transform of this aperture has a null at the spatial frequencies that would alias to low frequencies; this combined with a tiny bit more blur from the lens psf is plenty to keep aliasing to a usually invisible level, while keeping the image sharp and high-res.<br />
<br />
FoveonセンサーでAAフィルターが必要ないのは, サンプルがどこに位置しているのか, 空間サンプリング密度の違いは何か, というようなことに拠るものではない. 各サンプルが, ほぼ100%のフィルファクター(曲線因子, fill factor)を持つ全サンプル径から採られたものだからだ. つまり, どちらの次元方向にもサンプル・ピッチと同じだけの幅を持つ. 低周波数帯でエイリアシングを発生させる可能性のある空間周波数にて, この全サンプル径へフーリエ変換を施すとnullとなる; この結果は レンズpsf (Point spread function 点拡がり関数) 由来のより大きなボケと混ぜ合わさり, エイリアシングを気づかないレベルにとどめるに十分だ. 一方画像をシャープで高解像度に保つ. <br />
<br />
In the 1:1:4 arrangement, each sample layer has this property, but at different rates -- very unlike the Bayer's red and blue planes. The large area of the lower-level pixels is the ideal anti-aliasing filter for those layers; the top layer is not compromised by the extra spatial blurring in the lower layers, so it provides the extra high frequencies needed to make a full-res image.<br />
<br />
1:1:4配置において, 各サンプルレイヤーはこのような特徴を持つ. しかしその度合いは異なる. -- このことはBayerの赤プレーン青プレーンとはまったく様相が異なる. 下層ピクセルの大部分の領域は, 各レイヤーに対する理想的なアンチ・エイリアシングフィルターだ; トップレイヤーは, 下層での余剰な空間ボケ(spatial blurring)による劣化を起こさない. そしてfull-res画像生成のために必要な更なる高周波数を提供する. <br />
<br />
Another good way to think of the lower levels is that they get the same four samples as the top level, and then "aggregate" or "pool" four samples into one. This is easy to simulate by processing a full-res RGB image in Photoshop or whatever.<br />
<br />
もう1つ下層についてうまい考え方がある. 各下層はトップレベルと同様に, 同じ4つのサンプルを得る. そしてその4つのサンプルを, 1つへと"まとめる"或いは"プールする". この考え方はPhotoshopででも何ででも, full-res RGB画像を加工することで簡単にシュミレーションできる. <br />
<br />
The pooling of 4 into 1 is done most efficiently in the domain of collected photo-electrons, before converting to a voltage in the readout transistor. The result is the same read noise, but four times as much signal, so about a 4X better signal-to-noise ratio. Plus with fewer plugs, transistors, wires, etc. to service the lower levels, the pixel fill factor is closer to 100% with easier microlenses, and the readout rate doesn't have to be as high. Wins all around -- except for the chroma resolution.<br />
<br />
4つを1つへプールする処理は, 読み出し(readout)トランジスタの中で電圧に変換される前に, 集められたphoto-electron ドメイン内でもっとも効率よく行われる. そこから得られる結果といえば, 同等の読み出しノイズ, 4倍の信号, 従って4x良いS/N比. 加えて, 下層を動かすためのプラグ, トランジスタ, ワイヤetcはより少なくて済み, pixelフィルファクター(曲線因子)は単純なマイクロレンズで100%に近い. そして読み出し率はそれほど高い必要がない. 良いことだらけだ. -- Chroma 解像度についてを除いては. <br />
<br />
The main claim of Bryce Bayer, and the fact that most TV formats and image and video compression algorithms rely on, is that the visual system doesn't care nearly as much about chroma resolution as about luma resolution. Unfortunately, trying to exploit that factor with a one-layer mosaic sensor has these awkward aliasing problems. Doing it with the Foveon 1:1:4 arrangement works better, requiring no AA filter, no filtering compromises. So, yes, the chroma resolution is less than the luma resolution, but you'd be hard pressed to see that in images.<br />
<br />
Bryce Bayerの主張, またほとんどのTVフォーマットや画像や動画が依存している事実は次のようなことだ. 視覚系はluma (輝度) 解像度と同じようには, Chroma 解像度に対し敏感でない. 不運なことに, 単層モザイクセンサーでこの事象を利用しようとすると, 上で書いたような深刻なエイリアシングの問題に突き当たる. しかしFoveon 1:1:4 配置では, よりましな結果になり, AAフィルタを必要とせずフィルタによる劣化は起こらない. だから回答としてはyes, Chroma 解像度は, luma 解像度より低い. しかしそれを実際の画像で見分けるのは非常に難しいだろう. <br />
<br />
If you throw out the extra luma resolution and just make 5 MP images from this new camera, you'll still have super-sharp super-clean versions of what the old DP2 or SD15 could do. Now imagine adding 2X resolution in each dimension, but with extra luma detail only, like in a typical JPEG encoding that encodes chroma at half the sample rate of luma. Whose eyes are going to be good enough to even tell that the chroma is less sharp than the luma? It's not impossible, but hard.<br />
<br />
仮に増分のluma 解像度を放り捨て, この新しいカメラから5MP画像を単純に生成したとしたら, それでも旧DP2やSD15で生成できた画像の, スーパーシャープ, スーパークリーンなバージョンとなるだろう. 2倍の解像度を各次元に加えたと想像してみよう. しかしここでは新たに増えた分の luma ディテールのみを加えるのだ. これはまるでchroma を luma のサンプルレートの半分でエンコードする典型的なJPEGエンコーディングのようだ. その画像をみてchroma が luma と比べてシャープじゃないなどといったい誰が見分けられるのか?不可能とは言わない, がしかし難しい. <br />
<br />
Speaking of stories from the old days, Foveon's first version of Sigma Photo Pro had a minor bug in the JPEG output, as you probably recall: our calls to the jpeg-6b library defaulted to encoding with half-res chroma. It took a while, but a user did eventually find an image where he could tell something was not perfect, by comparing to TIFF output, and another user told us how to fix it, so we did. It we could have gotten that original level of JPEG quality from the SD9 with 5 million instead of 10 million pixel sensors and data values, and could have gotten cleaner color as a result, would that have been a problem? I don't think so; except for marketing, and they had enough problems already. Same way with Sigma's new one, I expect; if 30 M values gives an image that will be virtually indistinguishable from what could be done with 60 M, but with cleaner color, will someone complain?<br />
<br />
昔話をしよう. 覚えている人もいると思うが, FoveonのSigma Photo Pro最初バージョンには, JPEG 出力にマイナーなバグがあった: jpeg-6bライブラリへの呼び出しは, 50% のchroma 解像度でのエンコードをデフォルトにしてあったのだ. 時間はかかったがともかくTIFFからの出力と比較すると何かが欠けていると, それが分かるある一人のユーザが現われた. そしてまた別のユーザがそれについての対処法を僕ら伝えてきた. そうして僕らは修正できたのだった. SD9のもともとのJPEG品質レベルの画像を, 僕らは10M pixelセンサーの代わりに5Mセンサーからのデータで得ることが出来たのかもしれない. そしてそれは結果的によりクリーンな色情報を持つものだったのかも. それが何か問題になっただろうか?僕はそう思わない. マーケティングについては例外. でもマーケに関していえば, もうすでに十分な課題が山積していたからね. SIGMAのこの新しいカメラにも同じことが言えると思う; もし30M分の情報で, 60Mで得られるものとほとんど区別のつかない画像を生成できるとしたら, それで誰かが文句を言うのかな?<br />
<br />
Probably so.<br />
<br />
うん, まあ言うのかもしれない. <br />
<br />
So, it's complicated. Yes, reduced chroma resolution is a compromise; but a very good one, well matched to human perception -- not at all like the aliasing-versus-resolution compromise that the mosaic-with-AA-filter approach has to face.<br />
<br />
だから事態は複雑だ. その通り, Chroma 解像度を減らすことは, 1つの妥協だ. しかしとても筋のよい妥協で, 人間の知覚とよくマッチしている. -- これはモザイクとAAフィルターアプローチが面と向かうはめになる "エイリアシング-vs-解像度" による画質劣化といった事柄とは, まったく異質のものだ. <br />

Truman, I guess you missed the bit where I wrote "A lot of people seem to have the idea that aliasing has something to do with different sampling positions or density, as in Bayer. But that's not the key issue. ..." It must have been your comments that prompted that. What is "sub-alias sampling" supposed to mean?<br />
<br />
Truman, 君は僕が書いた "多くの人がベイヤーでそうであるように, エイリアシングが異なるサンプリング位置か密度となにか関係があると考えているようだが, それは大きな問題ではない..." という部分を見逃したのだと思う. これはこのことを示した君自身のコメントであるべきものだった. この"サブ-エイリアス サンプリング (sub-alias sampling)"とは具体的になにを意味するのだろう?<br />
<br />
Sure, there will be aliasing, as in all sampled images. If you consider the pixel pitch and pixel aperture, you can work out that the aliasing will be about like that of the SD15's sensor. That is, negligible; and that will only be in chroma, so even more negligible, visually. The key next step is adding a high-frequency luminance signal, uncorrupted by that aliasing. That's what's nearly impossible to get accurately in Bayer sensors, but trivial to get with the Foveon 1:1:4.<br />
<br />
そりゃそうさ, エイリアシングはある. サンプルされた画像全てにある. もし君がピクセルピッチとピクセル径を考慮しているのなら, エイリアシングはSD15のセンサーのそれとおなじようなものだと理解することができるだろう. つまり, 無視できる; そしてそれはchroma に対してのみで, すると視覚的に更に無視できる. 次のキー・ステップは, 高周波数の luminance 信号を加えることだ. これにはエイリアシングによる欠損がない. ここでベイヤーセンサーに正確性を求めることはほとんど不可能だ. しかしFoveon 1:1:4では簡単に得ることが出来る. <br />
<br />
But you are certainly right, as I also said, that we will wait and see. My words and yours are not going to convince anybody of anything until they see it.<br />
<br />
とは言え君はまったくもって正しい. また僕もそう言っているように, 待って見ようじゃないか. 実際に皆が実物を見るまで, 僕や君の言葉は誰も説得できやしないだろう. <br />
<br />
As I also said elsewhere, I'm both surprised and delighted, after 8 years away from Foveon, to see this concept making it into a Sigma camera. It shows that Kazuto had the courage to focus on image quality above all, not fearing the marketing difficulty of explaining the Foveon advantage a little differently and with lower pixel numbers than before. As Laurence said, Merrill worked on this idea from its inception; Foveon's cell-phone sensor project did enough testing to show it's a great idea. And I presume the rest of the Foveon team has continued to execute well on the potential in bringing it to the larger format. This may be Merrill's best legacy, even more than the ones named for him.<br />
<br />
前のポストでも言ったけど, Foveonを去ってから8年の後, このコンセプトがSIGMAのカメラに搭載されたことを目にしたことは, 僕にとっては驚きと喜び両方だ. 分かることは, Kazutoが何にもましてイメージ・クオリティにフォーカスする勇気を持ってたこと. 前よりやや少ないピクセル数になりFoveonのアドバンテージについて今までとは少し違う説明をしなければなならい, マーケティング的な難しさを厭わなかったこと, そういったことだ. Laurenceが言ったように, Merrillは当初からこのアイデアを実現しようとしていた; Foveonの携帯電話センサープロジェクトはこれが素晴らしいアイデアだと示すのに十分なテストはしていた. 後に残ったFoveonチームは, このアイデアをより大きなフォーマットへ適用できる将来性を見込んで, 首尾よく開発を継続し続けてきたのだと僕は推測するよ. これはMerrillの最も素晴らしい遺産と言えるかもしれない. 彼の名に由来するどんなこと以上にさ. <br />
<br />
If I may summarize once more what I think is the key point: the tradeoffs and compromises about how to utilize the Foveon concept and technology have been thought through here, and developed and tested for many years, in a way designed to maximize image quality at both low and high ISO. The 1:1:4 architecture is surprising and non-intuitive, but it is what best exploits what the silicon can do (as Carver said, years before we started Foveon, "listen to the silicon"http://www.wired.com/wired/archive/2.03/mead.html). Listening is not a theoretical exercise, nor something you do in computer models (though they help).<br />
<br />
ここでもう一度僕の考えるキーポイントをまとめるよ: Foveonのコンセプトとテクノロジーをどのように活用するのか, そこに生じるトレードオフと妥協の数々については, 低ISO, 高ISO両方で画質を最大限良くするデザインにする, という方向性で考え抜かれ, 時をかけてかけて開発・テストがなされてきた. 1:1:4構造は衝撃的でかつ直感的ではない. しかしこれはシリコンが出来ることを最も巧みに利用したものだ(僕たちがFoveonをはじめる何年も前にCraverが言ったように, "シリコンの言うことに耳を傾けよ"http://www.wired.com/wired/archive/2.03/mead.html). 耳を傾けるということは, 単に理論的考察を行うことではなく, またコンピュータ・モデルの中で何かゴニョゴニョするということでもない (もちろん助けにはなるけれども). <br />

As you may know, the factory of SIGMA is located in AIZU, Fukushima Japan. The products of SIGMA are still “MADE IN JAPAN”. Right after beginning of joint-project with SIGMA, Dick visited Japan with his wife.</span><span style="background-color: white; color: black; display: inline ! important; float: none; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;"> </span></span></span></li>

At the time he knew the project with SIGMA but didn't know where its factory resided. Well, typical places to go would be Tokyo or Kyoto, don't you think? But according to Dick, he was greatly attracted to Aizu after some research, so went straight to there from the airport.</span><span style="background-color: white; color: black; display: inline ! important; float: none; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;"> </span></span></span></li>

He obviously recognized the Aizu photos, and told Dick that Aizu was the place where the factory of SIGMA resides. So Dick and all participants in that meeting were very surprised and felt the magic.</span><span style="background-color: white; color: black; display: inline ! important; float: none; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;"> </span></span></span></li>

Because top layer performs on the best S/N ratio. Thus we capture the most detail information on the cleanest location (i.e. top layer) to have the best image quality.</span></span></span></li>

Talking about lens, SIGMA also has been focusing on interchangeable lens product line and receiving good reputation. We understand there is an opinion that sharpness of SIGMA lens is overkill in some cases, it doesn't have to be so sharp. But if a camera got high resolution sensor, lens also has to be high resolution capable, this is not questionable. So if it is said to be too much, SIGMA pursues releasing high resolution products, even though lens optics is dominated by classical physics therefore there is no overnight innovation. Stay tuned.<span class="Apple-converted-space"> </span></span><span style="background-color: white; color: black; display: inline ! important; float: none; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;"> </span></span></span></li>

<li>どうしようかと考えていたときに, Dick Merrillが3層構造のイメージセンサーのパテントを出した. </li>
<li>シリコンは光の波長の短い方から順に表面から吸収するという特性を持っている. </li>
<li>その特性に着目してシリコンで3層で光を取り込むというのをパテントとして出した.</li>
<li>もともとはナショナルセミコンダクターのトップエンジニアで, シリコンバレー界隈で非常に有名な方だった. </li>
<li>いつも難しそーな顔をして社内を歩いていて, 社内ではマッドサイエンティストとも呼ばれていて非常に有名な方. </li>
<li>でも本当に人柄は素晴らしい方で, 私が行っても, おぉ和人きたのかぁとかいって声をかけてくれて, サンノゼに出来たラーメン屋おいしいから行ってみろよーといって, わざわざラーメン屋のビジネスカードを渡してくれて, 日本人いっぱい来てるから絶対うまいはずだといって教えてくれたりした. </li>
<li>本当に優しい, 素晴らしい方だった. </li>
<li>ただ普段からラフな格好をしていてだいたいT-シャツにショートパンツというような恰好で社内をうろうろ歩いていた. 非常に社内では有名だったのだが, ある時新入社員が入って, Dick Merrillさんをみつけて掃除のおじさんと間違えて, ゴミ箱をちょっとこれ片づけといてと言って. 彼は普通だったら, トップエンジニアですからね, エグゼクティブに一番近いところなので, 何言ってんだっていえばいいのに, この人ユーモアがあるので, ははっかしこまりましたってゴミ箱もっていって捨てていて, それを見た周りの人が, Dickお前なにやってんのと. いや, あいつにさ, ゴミ箱捨ててって頼まれたんだよ, って言われて, 周りがびっくりして, その新入社員のところに行って, おまえあれは大変な人なんだぞと言われて顔が青ざめたという事件があるくらい, 非常にユーモアのある方. </li>
<li>残念ながら2009年癌でお亡くなりになっている. </li>
<li>当社と最高性能のカメラを一緒に作りたいという非常に希望を持っていたが, 残念ながら亡くなった. </li>
<li>今のMerrillシリーズは, この方の業績に敬意を払ってMerrillという名前をつけている.</li>
<li>もう1つエピソード. シグマの工場は福島県の会津にある. いまだにオールメードインジャパンでやっている. この方, はじめて日本に奥様と来た. これはシグマとジョイントのプロジェクトをはじめた直後くらいだった. </li>
<li>成田空港について, レンタカーで車を借りて一番最初に向かったのが会津若松市だったそうだ. 当時の彼は, シグマとプロジェクトを始めたというのは知っていたが, シグマの工場が会津にあるとは知らなくて, 行った. 珍しいですよね? ふつうは東京とか京都とかゆきますよね? でもなぜか色々調べて会津という土地に惹かれた, ということでまっすぐ成田から会津に向かったと. </li>
<li>で帰ってきて, 当時コダックのコダック・プロフェッショナル部門にあったデジタルカメラ開発をしていた人達とミーティングがあった. 時期としてはちょうどまだNikonさんがD1を出した直後くらい. </li>
<li>会津若松市の鶴ヶ城とか猪苗代湖とか, そういう写真を撮って帰ってきたあとに, 役員会で, 今のデジタルカメラは, ここが駄目なんだ, こういうところを直せばもっといいものになるんだということをプレゼンテーションした時に使ったのが会津の写真だった. </li>
<li>その役員の中に, シグマとのプロジェクトを始めるということで, シグマの工場にご招待した人がいた. で, あれっこれ会津じゃんていうことになって, そうだよ, 俺この前観光で行ったんだと. いやいや, そこシグマの工場があるところだよといって, みんな驚いたというくらいに, すごく不思議なご縁を感じるMerrillさんなのでした.</li>
<li>Merrillさんは, パテントは出したけど, 実現は不可能だと思っていたようだ. なかなか実際の製造・製品というのは難しいと思っていたようだ. </li>

<li>Raw専用機で全部パソコンで現像しなきゃいけない. これは大変怒られた. この後LightRoomやApature, SilkyPicsが出てきてRAW現像が良いものなのだという認識が広がったが, 当時は皆JPGだった. JPGが入っていないカメラなんて誰が買うのかと怒られた. 実際販売数は, ご指摘の通り少なかった. そういう変態チックなカメラだった. </li>

<li>なんでこんな1:1:4なんて構造をとったの? 今までと同じ1:1:1でいいじゃない?</li>
<li>巨大化するデータサイズ. 今回のトップレイヤーの2000万画素を1:1:1で作ると, おおよそ, 6000万画素相当のデータサイズになる. 非常に大きなサイズだ. Quattroは1:1:4構造することによって, 約3000万画素相当のデータサイズに抑えることに成功している. </li>
<li>今でもただでさえ遅いといわれている処理時間. ファイルサイズを小さくすることで高速化に成功している. </li>
<li>今回はTRUEIIIというプロセッサも導入していて, こればパワフルになっているということもあるのだが, dp2 Quattroで, ”平均的な”RAW画像, RAW画像は被写体によってファイルサイズがかなり変わるが, 平均的な画像を撮った場合の処理時間はだいたい5秒くらい. </li>
<li>今のDP2 Merrillは, データの読み出しから書き込みまでおよそ12秒なので, 半分以下位に高速化されている. </li>
<li>消費電力も改善していて, バッテリーが, ちょっと大きくはしたが, まだ最終的な開発をやってみないとわからないが, およそだいたい一回のチャージで200枚くらい撮れる.</li>
<li>信号特性の改善. 当然ながらミドルとボトムはより大きいフォトダイオードがあるので信号特性が良くなる. ということで若干高感度特性も良くなっている. </li>
<li>シチュエーションによっても違うので何とも言えないのだが, およそ, だいたい, 皆さんが使っていて平均的に1段分くらい改善したのかなというのは実感していただけると思う. </li>
<li>正直言って, 高感度はホントに苦手です. 他のカメラと比べてノイズはかなり多い. これは認めざるを得ない. </li>
<li>信号特性を改善したけれど, それほど高感度は良くない. これは100, 200, 400ぐらいまで, 安心して使っていただけるカメラ. 特に100, 200位で撮った時には, その「画質」というのはどのカメラにも負けないものをもっていると考えている. </li>
<li>あとQuattroセンサーが違うところは, MerrillセンサーではベースISO(基本感度)が ISO 200だった. 100で撮るとちょっと白とびがしやすかのだが, Quattroから100になっている. ですからISO 100から安心してガンガン使っていただきたい. </li>

<li>それは何かというと, 質感表現.</li>
<li>シグマのカメラで撮ったものはともかく質感表現がいいと評価を受けている. </li>
<li>質感, モニターでもプリントでも, そこにものがあるような, 岩でも, 錆びついた金属でも, まさに金属のクロームの表現でも, 水面とか, 氷とか, こういったものの質感がすごくいいと, 評価いただける. </li>
<li>これがシグマのカメラの特徴的なもので, シグマ内部では, Foveon Lookと呼んでいる. </li>
<li>端的に言うと, リアリズムのある表現, これがFoveonセンサーの特徴となっている. </li>

<ul>
<li>じゃなんでFoveonセンサーは質感のある画像が出せるのか?</li>
<li>まずはマイクロディテール(解像力). これが重要です. </li>
<li>デジタルカメラが1000万画素を超えたあたりから, いやいやそんなにね, 画素数上げなくてもいいじゃないの? これたくさん聞きました. まあ800万画素あれば十分でしょうと. あとはデータサイズがでかくなっちゃって使いずらいよ. </li>
<li>確かにデータサイズがでかくなると使いずらいのですが, 「殊, 画質」に関しては, 解像力は正義なんです. </li>
<li>解像力が上がる, ディテールが多い方が, 「必ず」, ホントにリアリズムのある画質になる. </li>
<li>写真として, しっかりとした質感のあるものになる</li>
<li>これは, 低解像度のカメラでは, 「絶対に」出来ない. </li>
<li>Foveonセンサーは解像度が高いので, リアリティのある写真が撮れるというのが1つ. </li>
<li>夢としてかなり遠い夢ではあるが, 8x10で撮ったような, しかもこんなでかいカメラを持ち歩かないで済む, 8x10で撮ったような写真を撮れるカメラを作りたい. それがSIGMAの夢だ. </li>
<li>被写体に依らない一定したディテール表現. </li>
<li>解像力の話はシグマのカメラに限らずどのカメラでも同じなのだが, 被写体によってディテールの表現力が変わらない, というのはFoveonの特徴. </li>
<li>一般的なカメラの場合には RGB のサンプリングが1:2:1で, サンプリング周波数が異なるので, 被写体によってはすごくきれいに解像するところと, ちょっとした色の構成によっては, 同じようには解像しないとか出てくる. それは拡大したときくらいしか見えないけれど. </li>
<li>そこの, 小さいマイクロ・ファインディテールがちゃんと出るか出ないかっていうのが, 最終的にリアリズムのある絵になるかどうかの違うを生む, そうSIGMAは考えている. </li>
<li>被写体に依らない一定したディテール表現がFoveonセンサーの特徴. </li>

<li>これはちょっと謝らなきゃいけない. </li>
<li>これはFoveonセンサーの分光感度表</li>
<li>Top, Middle, Bottom, この特性はFoveonセンサーを最初に作ったときから全く変わっていない. </li>
<li>ですので, 今までは, Blue, Green, Redと呼んでいたが, 実際にはもっと広い感度を各層が持っている. </li>
<li>ですので, 純粋な青とか言っていたのは, 正直言うと間違いだった. それを正すためにもRGB層というのをやめて, Top, Middle, Bottomというふうに言い変えそうと思っている. </li>
<li>まさにここが肝. </li>
<li>Top layerですでにディテールの情報の感度を持っているので, 輝度情報, ディテール情報はとれる. </li>
<li>なので, 今回Top layerで輝度情報, 解像情報, ディテールが取れる, というふうになっている. </li>
<li>なんで上なのか? というと, 上が一番信号特性, S/N比が良くとれる. ので綺麗な画像をとれるので, きれいなところで一番のディテール情報をとろうということで, 今回Top layerを4つにしている. </li>

<li>色は, 色相と明度と彩度の3つで決まるが, ちゃんとした情報がそこに来るので, 画像処理でやっても「補完」ではなくて, 「正しい」情報が4:4:4で作り出される. </li>

<li>もう1つ, 色解像度が落ちているのではないか? 1:1:4だから, 違うのではないかということについて. </li>
<li>そうじゃないという証拠はこれ. </li>
<li>参考までに, 3600万画素のベイヤーセンサーを使ったカメラで同じところを撮っている. </li>
<li>だいたい解像度は同じくらいなのだが, ディテールの出方がずいぶん違うのがお分かりいただける. ここに偽色とかモワレと呼ばれるものが出ている. </li>
<li>これはもともとベイヤーセンサーがRGBを1:2:1でキャプチャーしている. 色によってサンプリングしている周波数が異なるので, それによって色にじみが生じる. </li>
<li>それとピクセルのロケーション, 色のロケーションが違うので色ずれが生じ, 偽色が発生する. </li>
<li>Quattroの方は出ていない. </li>
<li>もしもQuattroセンサーの解像度が落ちている, 1:1:4のままであればここに偽色がでてくるはず. ここに偽色がでていないということは, 最終的な画質で4:4:4の画質にできている. 今までのX3と変わりませんよ, というのがこの証拠になる. </li>
<li>ですので, Foveonセンサーのことをよくご存じの方は, ベイヤーっぽいなーとか, ベイヤーになっちゃったんだとか, 心配されている方はどうぞこれを見て安心していただきたい. </li>
<li>今回の革新的な構造によって, データサイズを軽くして, これから, 更にピクセルを増やす, 更にディテールがとれる, 夢の中判とか, ちょっと相当遠い夢ではあるが 8x10, そういうところまで, 安心して突き進める, そういうテクノロジーを手に入れた. </li>

<li>イメージセンサーとレンズは車の両輪と同じくらい重要.</li>
<li>dp2 QuattroはDP2 Merrillと同じレンズを採用しているが, これはとりもなおさずDP2 Merrillに搭載されたレンズの解像度が十分高いからだ. </li>
<li>DP2 Merrillに入っているレンズは現代に販売されているレンズの中で, もっとも高解像度なレンズだといってもいいくらいだ. </li>

<li>レンズとセンサー, どっちかの解像度が落ちてもいい写真は撮れない. SIGMAは交換レンズにも力を入れていてご評価もいただいているが, ちょっとやりすぎじゃないの?そんなカリカリにあげなくてもいいんじゃない?みたいな声もきかれるこれども, やはり高解像度なsensorを積んでいるカメラであれば, 高解像度なレンズをやらないと意味がない. やりすぎと言われるかもしれないが, これからも, レンズは古典物理の世界で生きているので, そんなに簡単には上がらないのだけれど, これからも高解像度なレンズを追及してゆきたいと思っている. </li>

<li>ほんとに3000万画素以上のカメラを使うと, ちょっとしたものがすごく見える. ですので歩留りが下がる. </li>
<li>ですので, しっかりと右手でグリップして, 左手でレンズを支えて, きちっと撮る. こういうスタイルをお客様の撮影スタイルと想定して, でこういう形で後ろに出っ張らせて, レンズを出しました. </li>

<li>最後のスライド</li>
<li>レンズ一体型カメラのアドバンテージを説明したい. </li>
<li>レンズ交換式は本当に素晴らしいカメラだ. シグマは, 「レンズを変えれば写真が変わる」と, ずっと言ってきた. そういった意味ではシステムカメラというのは素晴らしいのだが, </li>
<li>こういった一体型のカメラにもアドバンテージはいっぱいある. </li>
<li>専用構成のレンズを設計できる. これは分りやすい. </li>
<li>レンズの光軸, 結像面に完璧にイメージセンサーをアラインメント(調整)できる. これは組立て, ラインで全部1つ1つ調整して出荷している. </li>
<li>普通のレンズ交換式のカメラは, フランジ面(マウント面)に対してイメージセンサーを調整して出荷している. </li>
<li>交換レンズは光軸をきちんとマウント面に対して調整して出荷している. </li>
<li>だからマウントというのはホント重要. </li>
<li>シグマのレンズのマウントパーツはすべて真鍮のパーツを使っているのだが, それが理由だ. </li>
<li>アルミは使っていない. それくらい, マウントのメカ精度は非常に重要. </li>
<li>高精細なカメラになればなるほど, マウントのメカ精度は非常に重要で, メーカーは本当に苦労していて大変. </li>
<li>いずれにしても, メカ精度に頼っているというところでは, このように完璧に調整しているというのにはかなわない. </li>
<li>ですから, 中心から周辺まで, 完璧に解像度が出るというのは, このレンズ一体型カメラの特徴になる. </li>
<li>ミラーショックがない. 一眼レフはミラーが動くので, 解像度が高いカメラは非常に難しくなる. </li>
<li>レンズシャッターなので, 非常に小さいシャッターが入っている. </li>
<li>レンズ交換式はフィーカルプレーンシャッター, これも比較的, ちょっとショックが大きい. </li>
<li>AF精度が高い. これはミラーレスカメラと同じ. 一眼レフカメラの場合は別のところに, ミラーで分光したAFセンサーが別のところにあって, そこでピントをとっている. ミラーレスと同じように写真を撮るところでピントを合わせているのでAF精度が高い. </li>
<li>シグマのカメラは, 色々オート機能がないので, デジタル画像からはじめて, カメラのオート機能に慣れた方だと, つかいづらいとか, じゃじゃ馬とか色々いわれて, 買ったけどすぐ売っちゃたとか, よくTwitterとかで見て, すごい心を痛めている. </li>
<li>確かに使いずらいカメラではあるとは思う. </li>
<li>だた申し上げたいのは, 本当に高精細な画像, High Resolutionな画像を撮るには, こういったことが恩恵として働いて, (それ故 SIGMA dpは)もっとも簡単に高精細な画像を撮ることができるカメラだ, ということは言い切れる. これを申し上げたい. </li>
<li>これは自分で使っての実感. 一眼レフはレンズがバタバタレンズが動くので, ブレなく, ピントを正確にあわせて撮るというのは, けっこう大変. </li>
<li>私はあまり写真の腕があまりよくないので苦労するのだが, dpは歩留り高い. 本当にびしっと写真が撮れる. </li>
<li>一番難しいけど, 一番簡単なカメラ(一番簡単に高精細な画像を得られるカメラ)という, ちょっと訳のわからない結論で, プレゼンテーションを終わりにしたいと思う. </li>
