摘要： A light source emits a light having a luminance. A light source luminance decision unit determines the luminance for a frame of the image based on pixel values of the frame. A conversion unit converts each pixel value of the frame in correspondence with the luminance. A light modulation unit displays the image by modulating a transmittance or a reflectance of the light based on each converted pixel value of the frame. A selection unit selects a timing to change the luminance in a display period of the frame by comparing the luminance for the frame with a luminance for a previous frame. A control unit changes the luminance of the light source to the luminance for the frame at the timing.

摘要： A largest value is selected from brightness data of sub-pixels of each pixel in an image, and a first light source luminance is calculated using the largest value. An average of the largest value of each pixel is calculated, and a second light source luminance is calculated using the average. By comparing the first light source luminance with the second light source luminance, an output light source luminance as a weighted average of the first light source luminance and the second light source luminance is calculated by setting a larger weight to a smaller one of the first light source luminance and the second light source luminance. A gradation of each sub-pixel is converted using the output light source luminance. A light source unit is controlled to emit the light having the output light source luminance.
