IMAGE DISPLAY DEVICE, CONTROL METHOD FOR IMAGE DISPLAY DEVICE, CONTROL PROGRAM, AND RECORDING MEDIUM

摘要

To suppress localized failure of a displayed video. An image display device comprising: an LED data calculation unit (22) that generates an approximation curve that has approximated distribution of input image values and has a variation of no more than a prescribed value, and calculates LED data on the basis of the generated approximation curve; and a liquid crystal transmittance calculation unit (23) that calculates liquid crystal transmittance on the basis of the input image and the approximation curve generated by the LED data calculation unit (22).
