Abstract

An image quality adjustment device includes: a lighting controller that controls a display panel including a plurality of pixels, each including arrangement of a plurality of subpixels such that the display panel displays a measurement image in which a part of the plurality of subpixels is lit; and a first electric filter that removes at least a spatial frequency component greater than or equal to fd/2 from a first image obtained by capturing the measurement image displayed on the display panel using an capture device when a panel spatial frequency determined by a pixel pitch of the pixel in a direction in which the plurality of subpixels are arrayed is set to fd.
