摘要： In order to suitably perform image processing on each partial area of an input image, an image processing apparatus divides an input image into a plurality of rectangular images, and performs image processing for each rectangular image. The apparatus stores intermediate information corresponding to each pixel in a rectangular image; performs image processing on pixel data of a rectangular image of interest based on the intermediate information, and generates intermediate information to be used in image processing on pixel data subsequent to the rectangular image of interest; and updates the intermediate information with the generated intermediate information. The apparatus updates the intermediate information based on given update period information that indicates an intermediate information update period.

摘要： Based on attachment position information of each of a plurality of sensor units, which reads an image in each area obtained by dividing the area of an original in a sub-scanning direction, image data output from the sensor unit undergoes attachment error correction of correcting the attachment error of the sensor unit. Image data output from the plurality of sensor units then undergo joint processing. Based on the placement information of the original, tilt correction of correcting the tilt of the original is performed for the image data having undergone the joint processing.
