Abstract

A luminance correction computation unitcorrects a luminance input signal L, which is inputted into a first luminance adjustment portion, to Lbased on the semi-transparent mirror luminance correction coefficient b, and the luminance correction computation unitcorrects a luminance input signal L, which is inputted into a second luminance adjustment portion, to Lbased on the semi-transparent mirror luminance correction coefficient b. As a result, an image of the first image display portion, which is reflected by a semi-transparent mirror, and an image of the second image display portion, which is allowed to transmit through the semi-transparent mirror, are corrected in order to cancel a luminance difference according to an optical characteristic of the semi-transparent mirror.
