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