摘要： The present invention relates to an image processing apparatus which can restore, from a color and sensitivity mosaic image acquired using a CCD image sensor of the single plate type or the like, a color image signal of a wide dynamic range wherein the sensitivity characteristics of pixels are uniformized and each of the pixels has all of a plurality of color components. A sensitivity uniformization section uniformizes the sensitivities of pixels of a color and sensitivity mosaic image to produce a color mosaic image, and a color interpolation section interpolates color components of the pixels of the color mosaic image M to produce output images R, G and B. The present invention can be applied to a digital camera which converts a picked up optical image into a color image signal of a wide dynamic range.
