Abstract:
1. A display apparatus comprising: a plurality of light sources; a display panel configured to output a display image based on an input image, with using irradiation by the plurality of light sources; and a processor coupled to a memory, configured to: accept a first input image and a second input image, compute a first light emitting amount of each of the plurality of light sources based on a luminance of the first input image, compute a tentative light emitting amount based on a luminance of the second input image of each of the plurality of light sources, on a basis of a comparison result between the first light emitting amount and the tentative light emitting amount, impose a limit on a change range from the first light emitting amount to a second light emitting amount of each of the plurality of light sources, and decide the second light emitting amount in a case where the display image is outputted based on the second input image in accordance with the limit; control each of the plurality of light sources on the basis of the second light emitting amount; wherein the processor is configured to accept a third input image prior to the first input image and the second input image, and wherein processor is configured to compute a third light emitting amount of each of the plurality of light sources based on the third input image and decides the second light emitting amount based on the first light emitting amount, the tentative light emitting amount, and the third light emitting amount; and wherein the processor is configured to set a value of the second light emitting amount within a range from a value of the first light emitting amount based on the limit in a case where a light emission change from the third light emitting amount to the first light emitting amount and another light emission change from the first light emitting amount to the tentative light emitting amount are different from each other; wherein the processor determines whether a direction of the change from the first light emitting amount to the tentative light emitting amount is on a plus side or a minus side for each light source of said plurality of light sources and imposes a limit of prohibiting light emission at the tentative light emitting amount in each of the light sources of said plurality of light sources whose change is sorted into a minority side among the plus side and the minus side.
