<p>To provide a device and a method for executing remosaic processing for performing conversion into an image of a different pixel array. Remosaic processing for inputting, as an input image, a mosaic image in which pixel blocks configured of a plurality of same-color pixels are arrayed, and converting the pixel array of the input image into a different pixel array is executed. In this remosaic processing, from among constituent pixels of the input image, pixel value gradients in eight directions in a conversion-target pixel location that is targeted for color conversion processing are detected, an interpolated pixel value calculation mode for the conversion-target pixel is decided on the basis of the pixel value gradients in the eight directions, and an interpolated pixel value for the conversion-target pixel location is calculated in accordance with the decided processing mode. For example, an image having a quadripartite Bayer-type RGB array in which colors of a Bayer-type RGB array are implemented as an array of 2 × 2 pixel units is converted into a Bayer array.</p> |
