摘要

PROBLEM TO BE SOLVED: To provide a data generation device for color unevenness correction, which can improve accuracy of a data for color unevenness correction.;SOLUTION: The data generating device 3 for color unevenness correction includes: a first sensor 41 for detecting light intensity of red light by each element and outputting it as first data; a second sensor 42 for detecting light intensity of green light by each element and outputting it as second data; a third sensor 43 for detecting light intensity of blue light by each element and outputting it as third data; a monochrome color image forming section 51 for forming a monochrome color image; a monochrome-color image picking up section 52 for picking up the monochrome color image; a white color image forming section 54 for forming a white color image; a white color image picking up section 55 for picking up the white color image; and a correction section 57 which detects influence by spectral distribution characteristics of a light source device from the respective first to third data when the monochrome image is picked up, and which generates the data for color unevenness correction, by correcting the first to third data when the white image is picked up, so that the influence can be eliminated from the first to third data, when the white image is picked up.;COPYRIGHT: (C)2010,JPO&INPIT
