Abstract:
Image data obtained by adding a dummy image to a periphery of inputted image data is divided into blocks which correspond to positions of LEDs. A light-emitting luminance of an LED in an image display area is determined in accordance with a maximum value among gradation values of pixels included in a block corresponding to the LED. A light-emitting luminance of an LED in an image non-display area is determined in accordance with an average luminance level of some of small blocks which are adjacent to the block corresponding to the LED in the image non-display area, the small blocks being obtained by further dividing a block of the image display area adjacent to the block corresponding to the LED.
