Abstract:
1. An image processing apparatus for compressing and storing image data, comprising: a division unit, adapted to divide the image data into pixel blocks, each pixel block being a group of a predetermined number of pixels; a compression unit, adapted to compress the pixel blocks divided by the division unit; a generating unit, adapted to generate packets of data, each of which corresponds to a pixel block compressed by the compression unit and includes a header indicative of information regarding the pixel block; a storage unit, adapted to store the packets of data and a packet table indicating a storage address of each pixel block corresponding to each packet generated by the generating unit; a setting unit, adapted to set information, indicating whether a second pixel block corresponding to a packet of interest is different from a first pixel block corresponding to a preceding packet, into the header of the packet of interest; and a storage control unit, adapted to store the second pixel block as a part of the packet of interest and store a storage address of the packet of interest in the packet table in a case where the header of the packet of interest indicates that the second pixel block is different from the first pixel block, whereas in a case where the header of the packet of interest indicates that the second pixel block is equal to the first pixel block, not storing the second pixel block, but storing in the packet table a storage address of the preceding packet as a storage address of the packet of interest.
