Patent ID: 8085427

Claim:
An image processing method configured to store, in a buffer, an image data of a prescribed bit quantity in a main scanning direction and a prescribed line quantity in a sub scanning direction, and to read out the image data stored in the buffer, the method comprising: storing, in the buffer, an image data of a quantity of c bits in a main scanning direction, wherein c is a common multiple of a number of bits m of a unit of memory access and a number p of bits in a single pixel, and the number of bits m of the unit of memory access is not a multiple of the number p of bits in the single pixel, and a quantity of y lines in a sub scanning direction; and reading out a pixel data, in the sub scanning direction, of p bits that configure the image data stored in the buffer, in response to a completion of the storage of the image data of the quantity of c bits in the main scanning direction and the quantity of y lines in the sub scanning direction.
