An image processing device (100) is configured such that an edge histogram creating section (130) calculates interproximal pixel luminance difference for each of pixels constituting a frame, and a first ratio, which is a ratio of pixels whose interproximal pixel luminance difference is greater than or equal to a first threshold, and an edge enhancement section (140) performs edge enhancement in such a way that a shoot component to be added is smaller for a frame having a larger first ratio.
