Abstract:
1. A pixel defect detection and correction device comprising: an average value acquisition section that acquires an average value of pixel values of adjacent pixels with different colors excluding a pixel whose defect is to be detected, which is a pixel of interest, in a processing region where a plurality of adjacent pixels with the same color and a plurality of adjacent pixels with different colors are arrayed with the pixel whose defect is to be detected in the middle; and a defect determining section that determines whether or not the pixel whose defect is to be detected is defective on the basis of at least the average value acquired by the average value acquisition section, wherein the defect determining section determines whether or not the pixel whose defect is to be detected is defective by comparison of the pixel value of the pixel whose defect is to be detected, the average value of adjacent pixels with different colors acquired by the average value acquisition section, and a designated different-color pixel threshold value, wherein the different-color pixel threshold value is variable according to a color of the pixel whose defect is to be detected which is a pixel of interest.
