摘要： According to one embodiment, a set unit sets a display luminance signal indicating a luminance of a display unit. A first calculation unit calculates a first gamma characteristic signal of an image to be displayed, based on the display luminance signal and gray-scale levels of pixels of the image. A second calculation unit calculates a second gamma characteristic signal of each area of the image, based on gray-scale levels of pixels of each area. A conversion unit converts a gray-scale level of each pixel of the image, based on the first gamma characteristic signal and the second gamma characteristic signal of an area including a pixel to be converted in the image. The display unit displays the image in which the gray-scale level of each pixel was converted, based on the display luminance signal.

摘要： A display luminance of an image signal is extracted from an image inputted. An observation distance is calculated as a relative distance between an observer and the display. A brightness of an environmental condition of the display is calculated. A visual angle of the image is calculated using the observation distance and a size of the display. A visual response function is calculated using the display luminance, the brightness of the environmental condition, and the visual angle. The visual response function represents relationship between the display luminance and a referential lightness of a human visual characteristic. A corrected display luminance corresponding to a referential lightness is calculated using the visual response function. The image is output on the display using the corrected display luminance.
