Abstract
An image display apparatus includes a plurality of display devices, a member arranged in the vicinity of the display devices, and a driving circuit to which an image signal corresponding to a quantity of light emitted from the light emitting region is inputted and which outputs a drive signal for driving the display devices. The driving circuit includes a correction circuit for correcting the image signal, with the drive circuit outputting the drive signal according to the corrected image signal. When the plurality of display devices is driven in accordance with the drive signal, a quantity of light emitted from a predetermined light emitting region correlating to a predetermined display device in the plurality of display devices is influenced by driving an adjacent display device and by the member. In a case where a first image signal as the image signal is inputted to the driving circuit within a first frame period, and a second image signal as the image signal is inputted to the driving circuit within a second frame period other than the first frame period, and the driving circuit outputs the drive signal corresponding to the second image signal, the correction circuit obtains a correction value to compensate for the influence caused by driving the plurality of display devices according to the drive signal corresponding to the first image signal, based on the first image signal, and the correction circuit corrects the second image signal based on the correction value and the second image signal.
