哪位来阐释一下最终照片的清晰度和相机的像素、镜头解像力的关系吧？如果最终图片
要求是低像素的高清图片，什么样的鸡鸡最好？

感光元件的尺寸和像素与图像质量是怎么样一个关系？以后会不会出现可变换感光元件
相机？就像可换后背胶片机？

中幅 + 可换数码后背
早实现了。

嗯，但这个是出于不同的目的，是为了救活胶片机。我说的是针对图片不同用途的不同
规格感光元件后背。现在感光元件一味追求高像素，忽略了低像素的需求。

可以学PhaseOne,需要高感的时候，4个像素合并成一个。
觉得不远了。
到时候全幅 36MP, 需要高感的时候，4个像素合并成一个, 9MP,也够用了。

呵呵，这绝对是个好主意，但愿N家C家赶快跟进。如果D3s上这个，估计都可以摸黑打
床罩了，连星光都不要了，哈哈

for in chip pixel binning to be better than merging RAW pixel digital
signals in post processing, the binning must happen on analog level.
That is: you add up the analog signal first, then amplify and digitize so
the analog signal is strong and the noises in amplier and digitizer circuits
are only introduced once on the summed signal.
If you merely add up the already digitized signal, then it already contains
the circuit noised from each of the pixels and it can be done equally well
with a RAW file in post processing.
but because digitization is done "in pixel" in CMOS chips, analog binning
across pixels is much more complicated to implement than in a CCD chip where
the analog signal is shipped off chip for processing. you d have to
implement additional circuits to send the analog charge from several pixels
(not necessarily neighbors due to the Bayer pattern) to one shared amplifier
possibly in one of the pixels in the group.
So I m not sure how quick the 135/APS camaras would adopt this technology.

那就用CCD咯，645D的那块40MP的sensor不就是CCD的，高感也挺不错，再高4倍那就更
