IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND PROGRAM AND MEMORY MEDIUM FOR EXECUTING IMAGE PROCESSING METHOD

摘要

An image processing apparatus characterized by including; an area sensor unit that reads from an original document image a plurality of frames of image data having a shift of less than one pixel, an output resolution acquisition unit that obtains an output image resolution at which resolution the original document image read by the area sensor unit is output, an acquisition frame number control unit that controls a number of frames read by the area sensor unit according to a result of the output resolution acquisition unit, a correction unit that corrects an inclination of the frames of image data controlled by the acquisition frame number control unit, and a high resolution conversion unit that performs an interpolation processing using the plurality of frames of image data whose inclination is corrected by the correction unit to obtain image data in a resolution higher than a resolution during reading.
