This invention reduces degradation in quality of a resized image in obtaining the resized image. An image capturing apparatus includes an image sensor which converts an optical image into an electrical signal, an A/D conversion unit which converts an image signal output from the image sensor into digital image data, a color interpolation unit which executes color interpolation of the digital image data, a separation unit which separates the digital image data that has undergone color interpolation by the color interpolation unit into a luminance component and color difference components, an image size conversion unit which converts the image size of the luminance component and color difference components, and a lossless compression unit which losslessly compresses the luminance component and color difference components generated by the image size conversion unit.
