Generate new processed image data from stored original image data with corrected setting for predetermined image processing while outputting processed image data before correction

Abstract

An image processing apparatus, including: an output image processing section which performs, on image data, predetermined image processing according to image formation; an output section that outputs processed image data, on which the image processing is performed, in accordance with an operation timing according to the image formation by an image forming section; a correction section which corrects setting of the image processing on the image data; an image processing control section which controls an operation of the output image processing section, stores the processed image data in an external storage section and controls the correction section to perform correction depending on a predetermined correction condition; and an output control section which reads out the processed image data from the external storage section and inputs the processed image data to the output section.
