Abstract

An image processing apparatus includes: 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.

Description

technical field [0001] The present disclosure relates to an image processing apparatus, an image processing method, and a program. Specifically, the present disclosure relates to an image processing apparatus, an image processing method, and a program that generate an image having a high dynamic range (wide dynamic range). Background technique [0002] A solid-state image pickup device such as a CCD (Charge Coupled Device) image sensor or a CMOS (Complementary Metal Oxide Semiconductor) image sensor used in a video camera or a digital camera works by accumulating electric charges corresponding to the amount of incident light and outputting an electric charge corresponding to the accumulated amount of light. The electric signal corresponding to the electric charge to perform photoelectric conversion. However, there is a limit to the amount of electric charge that can be accumulated in the photoelectric conversion element, so that when a certain amount of light has been recei...
