    摘要: There is provided an image processing apparatus including: an exposure compensation unit carrying out exposure compensation of a long exposure image and a short exposure image in keeping with an exposure ratio; a blur information measuring unit using the exposure-compensated images to calculate blur information showing a degree of discrepancy between pixel values at a corresponding pixel position in the long exposure image and the short exposure image; a blending coefficient calculating unit using the blur information to decide a blending coefficient to be used in a blending process on pixel values at the corresponding pixel position in the long exposure image and the short exposure image; and a blending unit carrying out the blending process on the pixel values at the corresponding pixel position in the long exposure image and the short exposure image using the calculated blending coefficient to decide the pixel value of an output image.
