Claim Text:
1. An image processing apparatus comprising: a pixel unit including a plurality of pixels to conduct long-time exposure and a plurality of pixels to conduct short-time exposure, an operating unit comprising a pixel information combining unit that performs a pixel value combining process on a long-time exposure pixel and a short-time exposure pixel, wherein the pixel information combining unit calculates a plurality of blending ratios based on pixel values of a plurality of pixels of different periods of exposure time, determine an applied blending ratio, which is applied to a blending process for the long-time exposure pixel and the short-time exposure pixel, by combining at least two of the plurality of blending ratios, and determine pixel values of an output image or an intermediate image which is applied to produce the output image, by the blending process for the long-time exposure pixel and the short-time exposure pixel to which the applied blending ratio is applied, wherein the operating unit outputs the output image to a signal processing unit.
