Claim Text:
1. An imaging apparatus that generates three-layer color data on the basis of a first mosaic image, the image processing device comprising: a color imaging element in which color filters are provided in a predetermined color filter arrangement on a plurality of pixels that are two-dimensionally arranged; a processing device configured to: acquire information of a lens which is used to capture an image; determine whether color mixture information used for color mixture correction is identified or unidentified on the basis of the lens information; read, from the color imaging element, from the color imaging element, a second mosaic image obtained by reducing the number of types of first pixels in the first mosaic image which includes a pixel of a first color formed by at least one color and a pixel of a second color formed by at least two colors other than the first color and in which the number of types of first pixels determined by the arrangement of pixels that are adjacent to a first pixel, which is the pixel of the first color, at a minimum pixel pitch in four directions is equal to or greater than 4, when the processor determines that the color mixture information is unidentified, and read the first mosaic image from the color imaging element when the processor determines that the color mixture information is identified; perform the color mixture correction for the first mosaic image when the processor determines that the color mixture information is identified; and generate colors of three layers from the first mosaic image subjected to the color mixture correction or the second mosaic image, wherein the first color is formed by a color having a higher contribution ratio for obtaining a brightness signal than the second color; and an encoder that encodes the image data processed by the image processing device.
