According to one embodiment, an apparatus includes following units. The image display unit includes a light source unit provided with light sources, each source being controlled respectively, and a liquid crystal panel displaying on a display area. The luminance calculation unit calculates a light source luminance of the light source based on a signal level of a divided area into which the display area virtually divided. The luminance distribution calculation unit calculates an entire luminance distribution of the light source unit. The transform unit transforms a signal level of the input image into a transformed image based on the entire luminance distribution. The luminance correction unit calculates a correction coefficient based on an average value or a sum of the light source luminance, and collects each of the light source luminance by the correction coefficient. The controller unit controls the liquid crystal panel and the light source unit. |
