那SONY还得问问三菱肯不肯呢……

此时的牛大正托着腮帮子苦思冥想：证据之二到底公不公开呢！

别吵了
让sony收购nikon吧
整合一下
天下太平了

不是这个你还认为是什么？点测光啊？呵呵
Canon的成功很大程度就是因为这种核心技术高人一筹。

自己看吧,

说的很清楚，Nikon 自己开发的。

"It is through our experience in developing the CCD, LBCAST, and CMOS sensors, with their diverse characteristics, that we’ve been able to come up with the ideal imaging sensor to best suit each particular camera."
Innovation Through Evolution: Nikon FX Format and Nikon DX Format
Nikon FX format: New proprietary large-format CMOS sensor

In line with our commitment to serve the evolving demands of photographers and nurture new forms of expression, Nikon has developed a proprietary new large-format imaging sensor — the Nikon FX format CMOS sensor — that differs from the Nikon DX format. Used in the D3, this innovative sensor, which measures approximately 36.0 x 23.9mm, features a high signal-to-noise ratio as well as a very wide dynamic range and greatly expanded ISO sensitivity range. This results in unprecedented high-quality, low-noise images and nearly the same image composition format as 35mm-film cameras, long the accepted protocol of leading photographers.Nikon FX-format CMOS sensor for the D3 Image area:Approximately 36.0 x 23.9mm Effective pixel count:12.1 megapixels Pixel size: 8.45 x 8.45 µm Sensitivity range (at normal setting):ISO 200 - 6400 Expanded sensitivity range:ISO 100 - 25600 equivalent

As the performance of imaging sensors continues to evolve at a remarkable speed, Nikon places a high priority on adaptability in matching each new camera with the most suitable sensor, to deliver the finest possible images. Since the introduction of the D1 in 1999, Nikon has developed CCD, LBCAST and CMOS image sensors of various designs and performance. Indeed, by applying our accumulated experience in image sensor design, we’ve managed to introduce countless innovations. Since Nikon considers it imperative to provide the best that imaging sensor evolution has to offer, in a camera photographers can truly appreciate, we are constantly strengthening our engineering and manufacturing techniques and processes. The Nikon FX format CMOS sensor, designed to meet the increased demands of the D3, is a reflection of our core philosophy and technological leadership.

Nikon DX format: Pioneered for the ultimate balance of performance and mobility

The Nikon D300, featuring a resolution of 12.3 effective megapixels, employs our DX-format CMOS sensor. This latest version of the Nikon DX-format imaging sensor, refined since its original appearance in the Nikon D1, is technically advanced. For the first time, Nikon has built A/D converters into the sensor, achieving high-speed data readout that enables continuous shooting at up to 8 frames per second* with low noise and minimal power consumption.

Nikon pioneered the Nikon DX format in the D1, emphasizing superior image quality with extra-high resolution in central areas of the lens.
The efficiently sized Nikon DX format also permitted Nikon to develop a more compact camera. With the Nikon DX format, the focal length of a lens appears to be increased by 50 percent, so a lighter, smaller telephoto lens can be used in place of a longer focal length lens, making equipment lighter and more portable. The D3’s high-speed, high-sensitivity capabilities may not be required for every shoot. And many photographers tend to bring a selection of camera bodies, lenses and flash units with them. When the D300, employing the Nikon DX format, is viewed in terms of a balance of performance and mobility, the advantages are many and persuasive.

估计也有国内企业保护意识在作怪。

完全不一样。
尼康索尼的合作模式等于英特尔请AMD代产服务器CPU，APPLE请诺基亚造手机。
OEM只有在互不构成直接竞争威胁的时候才是稳定的。

谢谢理解，呵呵。在下并非不懂得OEM，我要表达的是，OEM大致有两种情况，一种是主动的，就想你说的DELL和APPLE，他们掌握的品牌和核心技术。可以在很多的代工厂家里面进行选择，显示器你明基不做还有三星，有很多厂家等米下锅呢。还有一种是被动的OEM，比如尼康，他不得不对CCD或者CMOS进行OEM，而且选择的对象很少，几乎没有选择。尽管是自己设计，但是还是在某种程度上被别人卡脖子。再说，传感器的设计应该属于核心机密，还是越少的厂家知道越好吧？

在NIKON的网站上就有介绍，可能用的词汇不是你希望的，NIKON宣传的是他的照相机，不是CMOS。

我就一個疑問，要是自己開發的（我說是開發，生產找代工很正常），為什么一直不宣傳呢？為什么要遮遮掩掩的啊？

楼下某位XD看来不太了解现在电子行业很流行的OEM，DELL的显示器是明基做的，IPHONE是富士康做的。。。。太普遍了
核心设计和技术还是掌握在大牌厂家手里

你要这么理解我也没有办法

那不就对了，关键是设计，生产成本的控制也在设计之中。生产本身并没有什么，都是靠量赚钱。君不见半导体生产厂商多在劳动力成本低下的地区。

“那克隆羊还是肉做的呢，你做个出来试试？”这个就有点儿抬杠了。我是做不出来，可是我还是坚持我的论点，关键是设计，并不一定什么都要自己生产。

看来你不知道TSMC等台湾厂商是做什么的。NIKON可不是傻瓜，它肯定算过是自己建厂还是委托代工的成本，CCD和CMOS就是不同的生产工艺，如果是自己的CCD生产线那不是要关门了。

Intel,AMD在世界上再多的工厂，那也是Intel和AMD的，只是雇用了台湾的工人而已；索尼和尼康都在中国有厂，难道它们变成中国的了？
