Abstract
An image processor includes: an image sensor which outputs a short exposure image and a long exposure image; a sensor controller which controls first and second exposure sensitivities; a motion blending ratio calculator which calculates a motion blending ratio based on a motion amount of a subject; a motion-adapted image synthesizer which generates a motion-adapted image based on the motion blending ratio; and an HDR image synthesizer which synthesizes the motion-adapted image and the short exposure image, to generate an HDR image. The sensor controller controls the first exposure sensitivity: so that the first exposure time changes from increasing to constant and the first sensor gain changes from constant to increasing, when the brightness of the subject decreases from a first subject brightness; and so that the first exposure time changes to increasing and the first sensor gain changes to constant, when the brightness decreases from a second subject brightness.
