Abstract:
1. An image processing apparatus for entering thereinto image data comprised of a plurality of pixel data and for image-processing the respective pixel data to output the image-processed pixel data, the apparatus comprising: an image data storage unit configured to store “n” pieces of lines, each of which has “W” pieces of pixel data, and configured to store thereinto an input image data in order of the lines, where the “n” is predetermined value, and the “W” is predetermined value; an image processing circuit, which has a pixel data holding unit including “X” pieces of pixel data column holding units configured to hold the “n” pieces of the pixel data, where the “X” is a predetermined value smaller than the predetermined value “W”, and which executes an image processing operation by using a filter which has an “h” and a “g”, where the “h” is a predetermined value smaller than, or equal to the predetermined value “X”, and the “g” is a predetermined value smaller than, or equal to the predetermined value “n”; and an image data supplying unit which reads out the pixel data stored in the image data storage unit along a column direction, and supplies the read pixel data to the image processing circuit, the image data supplying unit configured to subdivide the image data into a plurality of image data blocks to supply the plural image data blocks to the image processing circuit when a total line number of image data to be image-processed is larger than the predetermined value “n,” and, the image data supplying unit configured to overlap one image data block preceding to a relevant image data block with a (g−1) line when the image data blocks are supplied to the image processing circuit after a second data block supplying operation.
