an image display device; and
a control unit,
wherein the image display device includes:
an image formation device; and
an optical device that displays an image emitted from the image formation device in front of an observer while superimposing the image on a real image of an outside world,
wherein the control unit controls an operation of the image formation device, and
wherein, in a case where a black display edge that is an edge of an area where black is displayed exists in the image, the control unit performs reversing processing and luminance increasing processing of the black display edge, and
wherein the control unit obtains an image of the black display edge obtained by performing reversing processing and by performing resolution reduction on the image, and thereafter performs combining processing of the image of the black display edge obtained by performing the luminance increasing processing on the image of the black display edge and an original image.
