Abstract
Provided are a display device, a computer program, a storage medium, and an image displaying method, which are capable of adjusting a light intensity of a display panel without using a photometric image. An optical sensor 5 measures the light intensity (tristimulus value) from a partial display area of a display panel (1) (measurement area of the display panel measured by the optical sensor (5)), and the partial display area has multiple pixels. A computation unit (20) computes the luminous intensity (tristimulus value) emanating from the measurement area based on a video level (image data) of each pixel for displaying an image in the measurement area. A comparison unit (19) compares the computed light intensity with the measured light intensity. A control unit (10) adjusts the light intensity (luminance, chromaticity, or the like) of the display panel (1) based on a comparison result by the comparison unit (19).
