LIGHTING DEVICE, IMAGE DISPLAY DEVICE, AND CONTROL METHOD FOR LIGHTING DEVICE

摘要

A lighting device includes a plurality of light sources corresponding to a plurality of areas of a screen, and a control unit configured to control at least one of a duty ratio between a lighting period and an light-out period and a drive current amount of each of the light sources based on input image data. The control unit controls lighting timings of the light sources in accordance with the drive current amounts of the light sources such that a fluctuation of the total of the drive current amounts of the light sources is suppressed.
