| 摘要 | 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. | ||

| 主权项 | 1. An image processing device, comprising: an image acquisition device configured to acquire 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; and a filtering device having a filter with a K×L (K, L: integers of M<K and N<L) filter size, the filtering device configured to apply convolution arithmetic operation to filter coefficients set for the filter and pixel values of K×L pixels extracted based on a target pixel in the image acquired by the image acquisition device so as to calculate a pixel value of the target pixel, wherein the filter coefficients set for the filter are weighted to be larger in a vicinity of a center of the filter, and the filter coefficients are set so that sums of the filter coefficients in the filter size, which filter coefficients correspond to pixels that are in identical positional relationship on the pixel configuration of M×N pixels, are all equal to each other. | ||
