Abstract:
1. An image processing apparatus which generates, from first image data having a first resolution, second image data having a second resolution lower than the first resolution, comprising a processor configured to implement: a determination unit configured to determine a pixel of interest in the first image data based on a ratio of the first resolution and the second resolution; a selection unit configured to select one of a plurality of filters in accordance with a position of the pixel of interest in the first image data that has been determined by the determination unit; and a generation unit configured to generate second image data having the second resolution by performing filter processing for a region including the pixel of interest by using the filter selected by the selection unit, wherein the ratio of the first resolution and the second resolution is not an integral multiple, and the filter selected by the selection unit is defined by filter coefficients regarding each of the pixel of interest and a pixel other than the pixel of interest included in the region in accordance with the ratio of the first resolution and the second resolution.
