Digital Camera terminology

photosensitive element must be used as a reference to determine the "black" value, and these pixels are not involved in imaging. Except for those not involved in imaging, the remaining pixels are active pixels; then some pixels are extracted from these pixels for a standard output (such as 2048x1536 ). In this way, we subtract the remaining recommendation record pixels, which we usually call effective pixels.  Resolution:  Resolution is directly related to valid pixels. For example, the maximum
