Photokina Q&A: Can the Samsung NX1 redefine pro performance with a quantum leap in technology? —— 中英文对照翻译
DE: Getting back to trade-offs with on-chip phase-detect AF, one of the big differences between the on-chip phase-detect and the conventional separate phase-detect sensors is that the conventional sensors have much larger pixels, and are consequently more sensitive to light compared to on-chip PD elements. So there’s a tradeoff in light sensitivity if you go to on-chip. What’s the low-light limit for the NX1?
DE: 回到芯片相位对焦的取舍上，芯片式相位检测和传统的分离式相位检测的重要区别之一就是传统的对焦传感器上的像素要大得多，因此和芯片式相位对焦相比对光线更敏感，所以如果选择了芯片对焦，会在光线灵敏度上有所牺牲。NX1弱光极限怎么样？
JK: I believe it is rated to EV-4 for contrast and EV-2 for P.D. But the tradeoff isn’t in the size of the phase-detect sensors, as you move from off-chip to on-chip. It comes in wavelength. So with the DSLR phase-detect sensors, you can run those wide open. You can run them into infrared, and that’s what most designers do. So if you look at DSLR autofocus assist lights, many are running red-infrared, which is less obtrusive. The autofocus assist lights are generally red-infrared, but if you go on-chip you have the IR blocking filter on the image sensor, so on-sensor you can’t use IR sensing for autofocus any more.
JK: 我想经过测试的对比度检测达到EV-4，相位检测达到EV-2，但从分离式转移到芯片式牺牲的不是相位传感器的大小，而是波长。在数码单反上，你可以最大限度地利用相位检测传感器，它可以检测红外线—-大部分设计者是这么做的。如果你观察数码单反的自动对焦辅助光，许多都是不怎么明显的红光到红外光。通常自动对焦辅助光都是红光到红外光，但是如果选择了芯片式，在图像传感器前面就有红外截止镜，所以在芯片上就不能再靠感应红外光来自动对焦了。
The Samsung NX1’s autofocus assist lamp nestles between the lens mount and hand grip. In this image of the unfinished chassis, it’s visible just right of where the shutter button would be.
DE: Ah!
DE: 啊！
JK: Make sense. Because you’re blocking the IR.
JK: 说明白点，因为需要阻挡红外光。
DE: Yeah, obviously, yeah.
DE: 对，很显然，对的。
JK: And so, the right strategy for on-chip AF assist ends up being visible spectrum, or in our case we’ve been using green lights for a long time. Now, the green light that’s in this one for AF assist is the most powerful AF assist light I’ve ever seen; it’s good out to 15 meters.
JK: 所以最后可见光才是芯片式AF辅助的正确方向，对我们来说我们长久以来一直使用绿色光。现在NX1中的用作AF辅助的绿光是我见过的最强大的AF辅助光，有效距离能达到15米。
DE: Wow.
DE: 哇。
JK: We’ve also added in a pattern…
JK: 我们还加入了图形……
DE: Yeah, it has that patterning; perhaps using a holographic grating or something to project the pattern.
[Sony used a holographic grating to project an AF pattern a few years back, but it didn’t persist in their product line. The reason I’m thinking they might be using a holographic grating to project it is that the pattern seems to stay pretty sharply-focused, regardless of the distance it’s being projected.]
DE: 对，有特定图形，也许是用了全息光栅什么的来投射这个图形。
[索尼几年前用过全息光栅投射AF图形，但没有在它的产品线上继续使用下去。我想原因可能是他们的全息光栅投射的图形过于集中了，不顾投射的距离。]
JK: It’s a line pattern, let me see if I can dial that up. Here, look at this, Dave. If you look at the back of your computer actually. [He’s projecting the AF-assist pattern on the lid of my MacBook.]
JK: 是线形的，我看看是不是能按出来。这里，Dave，看这个，看你电脑的背面。[他在我MacBook的盖子上投射AF辅助光的图形。]
The Samsung NX1’s autofocus assist lamp projects a pattern on subjects for easier focusing.
DE: Yeah, it’s got a whole bunch of vertical lines, both broad lines and fine lines. Presumably the broad lines help when the camera’s more out of focus, and the fine ones help it focus finely, once it’s close …
DE: 对，有一大堆竖线，有粗有细。想必粗线是在相机离焦点位置比较远的时候起作用，细线帮助相机在接近焦点位置的时候精确对焦。
JK: Well, if you’re in total darkness, you need a pattern.
JK: 唔，如果在全黑的环境下，你就需要图形了。
DE: Yeah.
DE: 是的。
JK: Total darkness on a flat surface.
JK: 全黑的平滑表面上。
DE: Right, the projected pattern means you’re not dependent on the surface that you’re aiming it at.
DE: 对，投射图形意味着你不再依靠相机对准的表面了。
DE: When we were talking previously, you said that the architecture of DRIMe V is very different than DRIMe IV. What sorts of changes are made between them?
DE: 我们之前谈到，你说DRIMe V的架构和DRIMe IV有很大区别，到底是什么样的变化呢？
JK: The biggest change is the structure of the Image Signal Processor. The DRIMe V ISP is very different. Most ISPs have key parts of the processing hardwired to get the needed speed. What’s really new with the DRIMe V is that the “hardwiring” can be reconfigured.
JK: 最大的改变是图像信号处理器的结构。DRIMe V的ISP（图像信号处理器，译者注）是很不一样的。多数ISP的关键部分是获得必要速度的处理硬连线，DRIMe V真正新颖的地方是”硬连线”可以被重新配置。
DE: That sounds very significant, although I have to admit I don’t know how common it is that ISPs are actually hardwired.
DE: 这听起来很有意思，虽然不得不承认我不知道这个常识：ISP其实就是硬连线。
The DRIMe V processor — pronounced “dream”, by the way — is here, and completely new. (Don’t be confused by the mention of “ARM” on the chip. It does have no fewer than 5 general-purpose ARM processing cores, but its real magic comes from the hefty array of hardwired image-processing modules it contains.
JK: There’s not much variability in them. Sometimes you’ll get thresholding changes and small numeric variables, but the image path is usually very locked down…
JK: 里面没有太多可变性。有时你可以修改一些阀值和修改一些小数值，但图像的路径通常被严格锁定。
DE: It’s pretty much, a fixed pipeline.
DE: 差不多是一条固定的管道。
JK: With a few tuning pieces, yeah.
JK: 加上一些调节阀，对的。
DE: Whereas this is more configurable.
DE: 而这个DRIMe V的ISP有更多的可配置性。
JK: Yes.
JK: 是的。
DE: And it’s configurable not at the level of changing a firmware program, but you’re actually changing the hardwiring. There are switches you can use to change the configuration of the functional units?
DE: 它的可配置性不是修改固件程序的程度，而实际上可以修改硬连线。是有能改变功能单元的设置的开关吗？
JK: Yeah, basically. And Samsung’s software people are all over it; they’re pretty sharp and I believe that we’re really going to be able to tap fully into the DRIMe V’s capabilities for the NX1.
JK: 对，基本是这样。此外三星的软件人员都扑在上面了，他们很厉害，我想我们真的会在NX1上充分挖掘DRIMe V的性能。
DE: So even though it’s hardwired, some of the connectivity is programmable through the firmware, so we can actually look for continued “firmware” development that would continue to improve performance, including the parts that are implemented in hardware.
DE: 所以尽管是硬连线，某些连接还是可以通过固件编程的，我们确实可以期待后续的“固件”开发不断改进性能，包括搭载在硬件上的部分。
JK: Yes.
JK: 是的。
DE: So there may be significant improvements in the near future. That’s pretty interesting, because it sounds like it’s already starting out pretty capable.
DE: 也许不久的将来会有一些显著的改进。这很有意思，因为听起来它刚起步已经有相当不错的能力。
JK: And not just image quality, there’s a lot going on in terms of programmability, like we talked about Samsung Auto-Shot mode before. Here’s the UI for it.
JK: 而且不仅是画质，已经有很多在编程方面进行的改进，像我们之前谈到的三星自动拍摄模式。这是它的用户界面。
This is the user interface for the NX1’s Auto Shot mode. The ball icon on the right side of the screen simply indicates that that’s the side the ball will be approaching from that direction – you can tell it to watch on the left as well. The camera will pick up the ball entering the frame anywhere on whichever side you’ve told it to watch; it doesn’t matter whether it’s high or low in the frame, it’ll catch any small, fast-moving, light-colored object moving, regardless of where it appears. The outline of the batter is just illustrative, the important part is the vertical red line on the left. The camera tracks the ball at 240 frames/second, measures its speed, and predicts when it will reach the red line.
DE: Ah – I’d been wondering what it looked like!
DE: 啊，我一直想知道它是什么样的！
JK: But that’s, you know, a perfect example of using that DRIMe V image processing. It does motion tracking at 240 frames per second, using hardware-based object recognition.
JK: 不过你要知道的，这是使用DRIMe V图像处理的一个完美示例：它使用基于硬件的物体识别，能做到每秒240帧的运动跟踪。
DE: And did I read somewhere that it’s not just tracking the baseball, but it’s actually watching the bat as well?
DE: 我好像在哪里读到过，它不仅仅在跟踪棒球，其实它也在观察球棒？
JK: No, just the ball reaching that position. The development team is working on things like that, but currently the hardware is just tracking the ball. What’s important to understand, though, is that this is all happening in hardware; that’s the way we can track something that fast.
JK: 不，只是跟踪球到那个位置。开发团队正在努力开发类似的功能，但目前硬件只跟踪棒球。重要的是要知道这个全部是在硬件上实现的，所以我们才能那么快地跟踪一样东西。
DE: Really? Oh!
DE: 真的？噢！
JK: Yeah, every four milliseconds, the DRIMe V hardware clocks in the image, searches for the ball, and calculates the ball’s position change and rate of change of position, and predicts the moment that the ball will pass the reference. The speed can vary over quite a range, but the hardware rejects objects moving too fast or too slow.
JK: 没错。每4毫秒，DRIMe V的硬件记录下图像，搜索棒球并计算球的位移和位移的变化率，预测棒球通过参考线的瞬间。球速可以在相当的范围内变化，但硬件会无视移动太快或太慢的物体。
DE: Yeah, so whether the guy pitches a fast ball or a slow ball, the camera will track it – it’s not working on a fixed time delay, it’s actually measuring the speed.
DE: 嗯，所以无论投手投出一个高速球还是低速球，相机都会进行跟踪：不是一个固定的延时，而真的在计算速度。
JK: Yeah, the ball speed can be anywhere from around 80km/h to around 160km/h [50 mph to 100 mph]. You can see that in the demo out in the booth — the laser dot “ball” alternates between fast and slow “pitches”.
JK: 对，球速可以是大约80km/h到160km/h之间的任何速度[50mph到100mph]。你可以看外面展台的演示——激光”球”点在高速”投”和低速”投”间变化着。
DE: The pitcher is changing it up, yeah.
DE: 投手正在改变速度，没错。
JK: Yeah, and you’ll see that the NX1’s pretty good about catching it at exactly the same point, regardless of the speed.
JK: 嗯，你会看到NX1总能在同一个点捕捉到它，无论快慢。
DE: How big is the window that it’ll recognize the ball? The UI shows a fairly small ball, how wide is the capture window for the ball?
DE: 识别棒球的窗口有多大呢？用户界面显示的是一个相当小的球，捕捉棒球的窗口有多宽？
JK: Anywhere on that side of the screen.
JK: 屏幕那边的任意位置。
DE: Oh, really? So anywhere that it enters that edge of the screen? That’s really interesting — when it’s clocking at 240 frames per second, is it just clocking data off of that part of the sensor? Is it just reading out a slice down the edge of the sensor, or does it read the whole frame?
DE: 噢，真的吗？球进入到屏幕那边的任意位置？这真的很有意思：每秒记录240帧，是只从传感器上记录那部分数据吗？是只读取传感器那一边，还是读取整个幅面？
JK: The entire frame.
JK: 整个幅面。
DE: Reading the entire frame? Wow…
DE: 读取整个幅面？哇……
Samsung NX1 circuit board with DRIMe V processor mounted. You may have noticed that on the chip itself, it’s written as DRIM V, with “engine” underneath; apparently the “e” in DRIMe stands for “engine.”
JK: It’s only searching for the ball on that side of the screen, though.
JK: 尽管它只在屏幕的那边搜索棒球。
DE: So, when it’s clocking it off at 240 frames per second, is it not sampling all of the pixels? It reads the entire frame, but not every single pixel? Or does it read every single pixel?
[I’m having a hard time believing the latter.]
DE: 那么每秒记录下240帧的时候，它不是全像素采样对吗？它读取整个幅面，但不是每一个像素？还是它读取每一个像素？
[我很难相信是后者。]
JK: Every single pixel.
JK: 每一个独立像素。
DE: Wow, so 28 megapixels, at 240 times a second.
[This is mind-boggling faster than anything else we’ve ever seen before, outside very specialized and insanely expensive scientific systems.]
DE: 哇，所以是2800万像素，一秒钟内读取240次？
[这是令人难以置信的快，超过我们之前见过的任何设备，除了非常专业又异常昂贵的科研系统。]
JK: Yeah, software can’t do that; this sort of thing is why we implemented such powerful hardware.
JK: 没错，软件是做不到这点的，这是我们搭载了这么强大的硬件的原因。
DE: Yeah, hardware for it. You said that it’s a hardware object recognition system, so it can recognize other kinds of objects too?
DE: 嗯，用硬件来完成。你说过它是硬件物体识别系统，那么它还能识别其它类型的物体吗？
JK: Yeah, it’s not specific to baseballs.
JK: 是的，不限于棒球。
Face recognition is handled in hardware — and that was true in earlier DRIMe versions too. This shot also shows the uniquely well-executed focus-range control that’s built into the forthcoming 300mm f/2.8 lens Samsung was also displaying at the show. To set the range, you slide the focus control switch on the side of the lens to the “set” position, and the camera shows both where it’s currently focused (the red bar under the distance numbers), and the range that you’ve set (the green bar below the red one). You can adjust both the near and far ends of the focus range with the camera’s control dials. Once set, slide the lens control to the “Custom” position, and the camera/lens will ignore subjects either closer or further than the range you’ve set. We’ve seen similar focus-control features before, but Samsung’s seems more powerul and the user interface is very straightforward and intuitive. The Samsung NX1’s fast sensor readout, large array of focus pixels, and fast processor make for speedy subject-tracking AF. (As with other features, though, we’ll obviously need to test this in the real world, before we can arrive at any firm conclusions.)
DE: So… faces and things like that too, or other objects?
DE: 那么……面部或者类似的东西，或者其它物体？
JK: Face recognition is actually handled by a separate hardware block.
JK: 面部识别其实是由一个独立的硬件模块控制。
DE: Oh, really? So even in the previous DRIMe, there was hardware for face recognition.
DE: 噢，真的？所以包括之前的DRIMe就已经有用于面部识别的硬件了。
JK: Right. So far we’ve only announced the baseball application, but they’re working on other kinds of sports applications, too.
JK: 对。目前为止我们只发布了棒球应用，不过他们（软件人员，译者注）也正在开发其它运动的应用。
DE: Ah – other kinds of sports. So it’s very much a sports application, but you’re looking at other sports besides baseball that it would be useful for. That’s really very interesting, it’s an interesting feature.
[Samsung wouldn’t give any hints of what other sports they might develop applications for, but I can easily imagine tennis, or the image of a ball coming off the golf club, etc.]
DE: 啊，其它类型的运动。所以很可能是一个运动应用，你在找棒球以外的运动，那会在……有用（套话，译者注）。很有意思，这是个有意思的功能（套话失败，译者注）。
[三星没有给任何关于他们可能开发应用的运动的暗示，但我能很容易想象到网球，或是高尔夫球脱出球杆的画面，等等。]
I wanted to come back to the data-readout speed. Is the camera actually capable of recording video at 240 frames?
我想回到数据读取速度上。这台相机究竟能在240帧的速率下录像吗？
JK: No.
JK: 不行。
DE: Oh, because the codec isn’t fast enough to compress and format it?
DE: 噢，是因为编码器不够快到足以压缩并格式化吗？
JK: Actually, we just didn’t implement that functionality, but the DRIMe V and the sensor could do it. When the guys in R&D were working on the Samsung Auto Shot feature, they recorded live 28 megapixel, 240 fps “video” to help with the debugging. We didn’t see there being an application for that, at least for very, very few people.
JK: 说真的，我们只是没有落实到功能上，DRIMe V和传感器是可以做到的。研发人员在开发三星自动拍摄功能的时候，他们录下了2800万像素、240fps（帧每秒，译者注）的“视频”用于调试。我们看不到这个功能的用途，起码非常非常少的人会用到。
DE: Yeah, 28 megapixels at 240fps is an awful lot of data; that high a frame rate probably wouldn’t be very useful for still photographers, and there’s no video format that big or fast…
DE: 是的，2800万像素240fps是非常多的数据，如此高的帧速大概对静态摄影师而言没有什么用，而且没有一种视频格式能……那么快那么多。
Going back to the processor itself how has your noise reduction processing changed as a result of having so much processing power available? What has that allowed you to do that you couldn’t do before the DRIMe V, in terms of the actual algorithms?
回到处理器本身，既然有了那么强的处理能力，降噪的处理有什么改变呢？能让你们在算法上做哪些在DRIMe V之前做不了的呢？
JK: The DRIMe V actually has a lot of IPs [small hardware circuit blocks] dedicated to noise reduction. It’s pretty cool; there are a lot of them, and each one does a different type of noise reduction processing, all at the same time. The DRIMe IV didn’t have these.
JK: DRIMe V实际上有很多IP（也许是Image Processor，图像处理器的缩写，译者注）[小的硬件电路模块]专门用于降噪。这个很棒，有很多IP，每一个都用于不同类型的降噪处理，都在同一时间进行。DRIMe IV没有这些。
DE: Really? So all these IPs can all be working in parallel doing their own noise reduction, and then some higher-level processor can come in and say, “Oh this is this type of image content here, so I’m going to use the output from this IP, but over here there’s different content, so I’m going to use the output from this other one”?
DE: 真的吗？这些IP可以同时进行各自的降噪，然后某些更高级别的处理器能介入并说：“噢，这里的图像内容是这个类型的，我要用这个IP的处理结果，不过这里又有不同的内容，所以我要用另一个IP的处理结果”？
JK: Yeah, yeah.
JK: 对，没错。
DE: Wow, I don’t know a lot about the details of image processors for digital cameras, but my impression has been that it was more software-driven. Here, though, all the different NR algorithms are being executed at the same time.
DE: 哇，关于数码相机图像处理器的细节我知道的不是很多，但我的印象中更多是由软件驱动的。可是在这里所有不同的降噪算法都在同一时间执行。
JK: Yeah, hardware’s the only way to do this.
JK: 没错，硬件是能做到这个的唯一方法。
DE: Yeah. Wow, that’s really interesting. And yet, because of Samsung’s advanced processing, the power consumption is quite low. How does power consumption compare to DRIMe IV?
DE: 对。哇，这太有意思了：然而，因为三星的先进制程，功耗相当的低。和DRIMe IV相比功耗如何？
JK: It’s actually a bit lower.
JK: 事实上DRIMe V功耗更低一点。
DE: It actually became lower, even though, even though there was such a huge jump in horsepower?
DE: 事实上还更低？即使，即使有那么大幅的功率提升？
JK: Yeah, because it’s a new semiconductor process for the DRIMe V.
JK: 对，因为DRIMe V用了新的半导体工艺。
DE: I think you said earlier that the DRIMe V had about twice the processing power, does that mean twice as many hardware units?
DE: 我想你之前说过DRIMe V有大约两倍的处理能力，是说有两倍的硬件单元？
JK: Yeah. It’s not just the number of units, though; with the 32nm design rules, there are a lot more gates in each processing unit.
JK: 对，不过不仅是单元的数量。得益于32nm的设计线宽，每个处理单元有了更多的闸极。
DE: And how many regular CPUs are there?
DE: 有多少个普通CPU在里面？
JK: Five general-purpose cores.
JK: 五个通用核心。
The Samsung DRIMe V image processor has five-cores — more than many desktop computers!
JK: Another important point is that the DRIMe V has the world’s first HEVC codec. (aka H.265)
JK: 另一个重点是DRIMe V是世界上第一个拥有HEVC（又名H.265）编解码器的。
DE: Ah, yes. I was just about to ask about that. So it’s also doing the H.265 encoding. And that’s presumably also hardware, I would think.
DE: 啊，对，我刚要问这个。所以它也能做H.265的编码，我想大概也是硬件在做。
JK: Right. If you check, I think it’s the first HEVC codec in a camera. That makes it pretty amazing as well. H.265 is a lot more sophisticated than H.264; you can get similar image quality with only half the data rate.
JK: 没错，如果你核对一下，我想这是HEVC编解码器第一次出现在相机里。它也确实做得很好，H.265比H.264先进很多，你只需一半的码率就能得到相似的画质。
DE: Ah, so for instance 100 MBits/s with H.265 is like 200 MBits/s with H.264.
DE: 啊，比方说100MBits/s（百万比特率每秒，视频码率单位，译者注）的H.265看上去就像200 MBits/s的H.264。
JK: Yeah, pretty much. Another important thing is that the NX1 has a low-latency EVF.
JK: 对，差不多是这样。还有一个重点是NX1配备了一个低延迟的EVF（电子取景器，译者注）。
DE: Latency, oh yeah, actually, I did want to ask that. So does that mean for viewfinder, because it says five milliseconds. So is that 200 frames a second?
DE: 延迟，噢对，其实我早就想问了。延迟是5毫秒，是指取景器吗？所以是每秒200帧？
JK: No, actually the display refreshes at about 54 fps, but the key thing is that the EVF and the sensor are synchronized. The two are genlocked, so there’s always just a 5 ms lag between what’s hitting the sensor and what’s being displayed on the EVF’s current scan line. I think we’re the only ones who can do this.
JK: 不，实际上显示器的刷新率大约是54fps，但关键是EVF和传感器是同步的。两者信号同步，所以从光线抵达传感器到显示在EVF当前扫描线上仅有5ms的延迟，我想我们是唯一能做到这个的。
DE: The video streaming through HDMI port, is that 4:2:2 on everything?
DE: 所有通过HDMI端口输出的视频流都是4:2:2（色度抽样比例之一，译者注）吗？
JK: It’s 4:2:2 out the HDMI 1.4 port; it’s 4:2:0 as it goes to the SD. And it’s H.265 to the card for both HD and 4K, so whatever video mode you’re saving to SD card, it’s using H.265, so you’re going to get much more efficient and better-quality HD out of it.
JK: 在HDMI 1.4端口上是4:2:2输出；到SD卡的是4:2:0。输出到卡上的高清和4K视频都是H.265，所以无论你选择什么视频模式存储到SD卡都是用H.265编码，你就能从中获得更高效率和高质量的高清视频。
DE: What’s the maximum bitrate to the card?
DE: 存储到卡上的最大码率是多少？
JK: I don’t have a bitrate yet, but it’s much more efficient compression. It requires more computing power to do it, but just as a rough example, I can run a Class 10 card through this, no problem. To do H.264 on, let’s say, a competitive piece, I need a UHS-3 card.
JK: 我还不知道码率的数据，但H.265在压缩比上要高效得多。它需要更多的计算能力才行，一个大概的例子，我能用c10（SDHC卡速等级，最低写入10mb/s，译者注）的卡保存H.265，没问题，如果是H.264，假设差不多的情况，我需要UHS-3（SDHC卡速等级，最低写入30mb/s，译者注）的卡。
DE: So it’s really a whole different metric with H.265; you can’t just directly compare megabits per second with data rates for H.264. It seems that 100 megabits here is going to be like 200 megabits there, so just looking at the data rate isn’t going to translate directly into video quality.
DE: H.265真的是一个完全不同的标准，你不能直接和H.264比较每秒多少MBits的码率。看上去这里的100MBits和那里的200MBits差不多，但只看码率是不能直接转化成视频质量的。
JK: Right, right. The image quality for H.265’s better. The noise reduction, or the compression artifacting is less, but it’s twice as efficient in terms of space.
JK: 对，没错。H.265的画质更好，降噪啊，还有更少的压缩伪像，不过在存储空间上有两倍的效率。
DE: That’s about it for my questions, and I see we’re also about out of time. Wow, that was sure a lot of ground we covered, thanks for the time and all the info!
DE: 我的问题问得差不多了，时间也快到了。哇，我们真的谈到了很多内容，感谢你的时间和所有的这些信息！
JK: No problem!
JK: 不客气！
