Image Processing Device, Imaging Device, Image Processing Method, And Program

Abstract: Provided are an apparatus and a method for generating a wide dynamic range image on the basis of one picked up image. Exposure time control wherein different exposure times are set by pixel region unit such as row unit of a pixel unit is performed and a plurality of different pieces of pixel information i.e. the pixel values of the pixels respectively having the different exposure times set thereto are acquired. For instance high sensitivity pixel information is acquired from a long time exposure pixel and low sensitivity pixel information is acquired from a short time exposure pixel and the pixel values of an output image are calculated on the basis of the pixel information with the different sensitivities. For instance in a high luminance region since there is a possibility that the sensitivity pixel information is a saturated value the weight of the low sensitivity pixel information is set large and since it is estimated that the SN ratio of the low sensitivity pixel information in a low luminance region is low the weight of the high sensitivity pixel information is set large and output pixel values are determined.
