Abstract: An image processing device includes: a computation unit that calculates signal values of a plurality of second colors by using signal values of a plurality of first colors obtained from an image sensor; a saturation determiner that determines whether or not at least one of the plurality of first colors is saturated by using the signal values of the plurality of first colors; and a corrector that corrects at least one signal value of the plurality of second colors and outputs a corrected signal value, when the saturation determiner determines that the at least one of the plurality of first colors is saturated.

Abstract: An image processor includes: an image sensor outputting a short exposure image and a long exposure image; a sensor controller that, when brightness of the subject changes, controls first exposure sensitivity to cause the short exposure image to have first brightness and controls second exposure sensitivity to cause the long exposure image to have second brightness; a motion blending ratio calculator calculating a motion blending ratio based on a motion amount of the subject; a motion-adapted image synthesizer generating a motion-adapted image by synthesizing a corrected short exposure image and the long exposure image based on the motion blending ratio; and an HDR image synthesizer generating an HDR image by synthesizing the motion-adapted image and the short exposure image together. When the subject becomes darker, the sensor controller controls the first and second exposure sensitivities to cause the first sensor gain to be at most the second sensor gain.
