ABSTRACT:
An image processing method comprising: reading out corrected data from a memory which prestored the corrected data, by referring to low P bit (P is an integer number ≧1, and ≦to M) in M bits digital image data (M is an integer number ≧to 2); calculating corrected data based on data for operation read out from the memory which prestored the data, wherein the data is read out by referring to high R bit (R is an integer number ≧1, and ≦M−1) in the digital image data; and outputting the read-out corrected data in a case that a value of the digital image data is not greater than a predetermined value, and outputting the calculated corrected data in a case that the value is greater than the predetermined value.
