Abstract
An image processing device carries out processing in a processing unit of 3-blocks. Data of 192(=64×3)-pixels is required in the processing of 3-blocks. This is an amount of data corresponding to 16-cells. When 3-blocks and 16-cells are arranged along an scanning direction of an image, both ends of them in the scanning direction are aligned.
Claims3
An image processing device comprising:
- a memory that stores therein data related to an image before or after processing;
- and
- an image processor that processes the data related to the image,
- wherein a region corresponding to a unit in the image processed by the image processor is defined as a block;
- wherein a region smaller than the block corresponding to a unit of data in the image transferred between the memory and the image processor is defined as a cell, and
- in a case where when one block and a plurality of cells are arranged along a scanning direction of the image, both ends of them in the scanning direction are not aligned, the image processor carries out processing while defining at least two blocks as a processing unit such that the at least two blocks and a second plurality of cells are arranged so that both ends of them in the scanning direction are aligned, wherein the second plurality of cells is greater than the plurality of cells.
