The display device is provided with: a display panel (2) that displays an image; an optical sensor (5), which is disposed facing the display surface of the display panel (2) and measures the radiation value of the light emitted by the display panel (2) as a measured optical value; a measured value-revising unit (1), which revises a revision target measured optical value that is a measured optical value to be revised using a function that represents the amount of change in the measured optical value per unit time and outputs same as a revised measured optical value; and a signal processing unit (4), which generates from the revised measured optical value a control value for controlling the display panel (2) to stabilize the display quality of the image displayed on the display panel (2) and generates a post-processing video signal that displays an image from the control value and an input video signal supplied from an external device. The function represents the change in the radiation value, when measuring the revision target measured optical value, during a disabled period in which the signal-processing unit (4) disables the stabilizing function that keeps the radiation value of the light source (3) of the display panel (2) constant. |
