Abstract:
1. An image reading device comprising: a two-side-data arbitrating unit configured to obtain read data on a main-scan-line-by-main-scan-line basis from a first image sensor that reads one side of a document and read data on a main-scan-line-by-main-scan-line basis from a second image sensor that reads the other side of the document, the two-side-data arbitrating unit transferring a piece of read data obtained from the first image sensor and a piece of read data obtained from the second image sensor alternately; a sub-scanning-data reducing unit configured to perform reduction in image data including the read data in a sub-scanning direction in a way that discards the transferred piece of read data corresponding to a main scan line according to setting to perform thinning on the pieces of read data corresponding respectively to main scan lines; an image processing unit configured to perform image processing on the read data having undergone the thinning; and a transfer unit configured to transfer the read data having undergone the image processing to another unit.
