Each pixel has two attributes at least: ______ and gray-level value.

Motion vector tries to match each block in the actual picture to content in the previous picture. Matching is made by shifting each of the _____x_____ blocks of the two successive pictures pixel by pixel each direction.

Why does the pixel-based approach lead to the error recognition of focusing pixels? A: focus measures are susceptible to noise B: the depth of field C: image misalignment D: The effect of defocus pixels

图像分辨率单位是() A: dpi B: ppi C: lpi D: pixel

CCD sensor is poor in terms of sensitivity and image quality. The reason is that each pixel of CCD needs an A/D, which reduces the photosensitive area of each pixel. In addition, the use of pixel equivalent A/D converter will also cause high noise interference. ( )
