Abstract:
An image processing apparatus that inputs a plurality of color image data and a reading position of an image sensor corresponding to the color image data at predetermined intervals, comprisingimage converting means for converting the plurality of color image data into luminance image data and chrominance image data; position error detecting means for detecting a position error of the reading position of the image sensor employing the luminance image data, and calculating a position correction value for correcting the position error in a direction of suppressing; first storing means for storing the luminance image data in a first memory; and second storing means for thinning and storing the chrominance image data at each predetermined interval in a second memory, wherein a position error of the chrominance image data stored in the second memory and the luminance image data stored in the first memory are corrected employing the position correction value in order to obtain a synthesized image.
