An image sensor includes a photodiode disposed in a semiconductor material to generate image charge in response to incident light, and a first transfer gate is coupled to the photodiode to extract image charge from the photodiode in response to a first transfer signal. A first storage gate is...
因为暗部信息为0,所以我们认为背光强度不足,当我们试着增大背光亮度,远超sensor感光极限,但是还是发现总有多阶暗部信息一直为0。 至此,我们判断该问题应该为相机对弱光信号处理出现问题,或者是Sensor感光性能出问题、或者是暗部过度降噪、或者是BLC不正确等原因。这种情况下,负责相机驱动和ISP的图像工程师,应及时对...
Image of an HDR scene with local tone mapping Dynamic Range (DR) is the range of exposure, i.e., scene brightness, over which a camera responds with good contrast and good Signal-to-Noise Ratio (SNR). This is a scene-dependent image quality factor that incorporates sensor sensitivity, noi...

An image sensor having a broad operation range obtains images each having a different exposure degree through a pair of pixels each having a different exposure degree, and combines the images to generate an image having a broad luminance range. The image sensor comprises a pixel array where a ...

Imax 是Imager的最大不饱和电流---也可以说是sensor刚刚饱和时候的电流 Imin是Imager的底电流(blacklevel) 。 Dynamic range potential of various image sensor types Note: the maximum dynamic range is never quite achieved, since in practice the noise level takes up to ~2 bits off the useful pixel ra...
A neutral-density filter (ND filter) is usually made of glass. It attaches to your camera lens and lessens the amount of light that passes through it. With less light coming in, you can adjust the shutter speed to lengthen exposure time or raise the camera’s image sensor or widen the ...
