Abstract
An image-processing apparatus for processing images, whereby the image-processing apparatus includes an image capture unit, a filter, and an extraction unit. The image capture unit acquires image signals composed of multiple color components of a 2×2 color-coding array. The filter then calculates an average pixel value associated with any (2n−1) pixels acquired by the image capture unit, whereby each of the filtered (2n−1) pixels include a target pixel and adjacent pixels having the same color component as that of the target pixel, and the calculated average is designated as the average of the target pixel and the adjacent pixels. At the extraction unit the pixel having the average calculated by the filter as the pixel value is extracted at an extraction rate of 1/(2n−1), where n is a positive integer value.
