Abstract:
1. An image data combining apparatus for combining m lines (where m is an integer equal to or greater than 2) of pixel data that have been output from a reading unit, wherein the reading unit has at least one line sensor that divides a portion of the image data into m lines of pixel data and outputs the m lines of pixel data into a memory that has a width direction and a height direction, such that each of the m lines is stored in the width direction, said apparatus comprising: an access unit configured to access the memory; and a determination unit configured to determine an upper address used for accessing the memory by said access unit, based upon first data that relates a position, along the height direction, of the m lines of pixel data stored in the memory, and to determine a lower address used for accessing the memory by said access unit, based upon second data that relates a position of the width direction in the m lines of pixel data stored in the memory, wherein the lower address includes values in which a portion of a plurality of bits constituting the second data are interchanged in such a manner that when the first data and the second data increase sequentially, p items (where p is an integer equal to or greater than 1) of pixel data output from each of the m lines of pixel data will be extracted from the memory each time, and such extraction is performed successively.
