Image data processing apparatus, image data processing method, and computer-readable, non-transitory medium

An image data processing method comprising:

• storing in a storage unit a first pixel block and a second pixel block taken from image data in which pixels are arranged in a first direction and a second direction which is different from the first direction;
• and
• writing, by a computer, the first pixel block and the second pixel block stored in the storage unit into a memory, wherein
• the first pixel block and the second pixel block are arranged one adjacent to the other along the first direction, and the number of pixels arranged in the first direction in each block is equal to an access unit data length of the memory multiplied by a natural number m1, and
• pixel data equal in length to the access unit data length, and representing pixels contiguously arranged along the first direction across the first and second pixel blocks, are written into the memory in a single access operation.

A computer-readable, non-transitory medium storing a computer program, wherein the computer program causes a computer to execute a process, the process comprising:

• storing in a storage unit a first pixel block and a second pixel block taken from image data in which pixels are arranged in a first direction and a second direction which is different from the first direction;
• and
• writing the first pixel block and the second pixel block stored in the storage unit into a memory, wherein
• the first pixel block and the second pixel block are arranged one adjacent to the other along the first direction, and the number of pixels arranged in the first direction in each block is equal to an access unit data length of the memory multiplied by a natural number m1, and
• pixel data equal in length to the access unit data length, and representing pixels contiguously arranged along the first direction across the first and second pixel blocks, are written into the memory in a single access operation.
