Summary:An image processor according to the present embodiment includes an acquirer, an output unit, and a generator. The acquirer acquires a first pixel value obtained by making a pixel value in a first image captured in a first exposure time correspond to a predetermined sensitivity and a second pixel value obtained by making a pixel value in a second image captured in a second exposure time shorter than the first exposure time correspond to the predetermined sensitivity. The output unit outputs a pixel value serving as a predetermined value larger than the second pixel value when the first pixel value has been saturated and the second pixel value corresponding to the first pixel value is less than the first pixel value. The generator generates a high dynamic range image using at least the first image and the second image based on the pixel value output by the output unit.
