ABSTRACT:
An object of this invention is to prevent an increase in image data while preventing degradation of the image quality caused by an image process in a digital image processing system. To achieve this object, a signal processing apparatus which quantizes pixel values within a pixel area having M (M is an integer of 2 or more) pixels into data of 2Nsteps by N bits (N is a positive integer) expresses a decimal part of data in the entire pixel area by increasing or decreasing by one a predetermined number of pixel values among the M pixels on the basis of the decimal part of the data in the entire pixel area.
