An image processing device includes an image signal acquisition section that acquires image signals that include signals of an object image from an image sensor, the image sensor being configured so that the object image is formed in an imaging area via an optical system, and is not formed in a non-imaging area, a processing target area setting section that sets a processing target area to an image of an image signal acquired area so that the processing target area is included in the imaging area, the image signal acquired area being an area in which the image signals have been acquired, and the processing target area including pixels used for a grayscale transformation process, and a grayscale transformation section that performs the grayscale transformation process based on pixel values of the pixels included in the processing target area.
