COLOR SHADING CORRECTING APPARATUS OF IMAGING APPARATUS, IMAGING APPARATUS, AND COLOR SHADING CORRECTING METHOD OF IMAGING APPARATUS

摘要

PROBLEM TO BE SOLVED: To accurately correct color shading characteristics even when shading characteristics are asymmetrical vertically and horizontally with respect to an optical axis and when the shading characteristics are different for each color filter due to dispersion in a manufacture process.;SOLUTION: The color shading correction apparatus includes a standard shading information storage part 411a' for storing standard shading information that the imaging apparatus has and an intrinsic shading information storage part 411a for storing the shading information of respective colors that each imaging apparatus has, and color shading correction coefficients for respective colors can be calculated by a color shading correction coefficient preparation part 411b on the basis of each shading information. When performing photographing, the color shading correction of picked-up images is performed by a color shading correction part 412 on the basis of the calculated color shading correction coefficients.;COPYRIGHT: (C)2008,JPO&INPIT
