Abstract
A micon unit () performs, along at least one direction within the plane of planar light, brightness correction processing for adjusting brightness distribution of the planar light on light source color video signals (RSd, Gsd and BSd) so as to change them into light source color video signals (RSd', GSd′ and BSd′), and the micon unit () further calculates the total light emission power of all LEDs () based on the light source color video signals (RSd′, GSd′ and BSd′), and performs, when the total light emission power exceeds an allowable light emission power, light emission power correction processing on the light source color video signals (RSd′, GSd′ and BSd′).
