Claim 14:
15. The image processing device according to claim 11, wherein the extraction circuit comprises:
a generation sub-circuit, configured to generate a pixel selection window;
a cache sub-circuit, configured to cache data of the pixels in N rows in the input image, wherein N is an integer, and a value of N is equal to a row size of the pixel selection window;
a first selection sub-circuit, configured to select, through the pixel selection window, the pixels in M columns from the data of the pixels in the N rows as the first pixel group, wherein M is an integer, and a value of M is same as a column size of the pixel selection window; and
a second selection sub-circuit, configured to control the pixel selection window to slide M columns in a preset direction, and select the pixels in the M columns from the data of the pixels in the N rows as the second pixel group.
