Abstract
A method for image processing according to one aspect of the presently disclosed subject matter includes: a step of acquiring an image taken by an imaging device including an image sensor having pixel configuration with repeating cycles of M×N (M, N: integers of 2 or more) pixels; (a) a step of setting a target pixel in the acquired image and extracting K×L (K, L: integers of M<K and N<L) pixels based on the target pixel; (b) a step of calculating a pixel value of the target pixel with an operation with use of a filter which has a K×L filter size and which has specified filter coefficients arrayed therein; and a step of repeatedly executing the step (a) and the step (b) while moving the target pixel one pixel at a time with respect to the acquired image.
