Abstract

The embodiment of the invention provides a display device and a display method, the display device comprises a display and a controller, the controller is connected with the display, and the controller is configured to obtain the average brightness of a to-be-displayed image and a brightness histogram of the to-be-displayed image. The method comprises the steps of: if the serial number of the first target interval is different from the serial number of the second target interval, obtaining a first proportion; correcting a contrast control curve of the to-be-displayed image according to the first proportion; correcting the to-be-displayed image by using the contrast control curve to obtain a corrected to-be-displayed image; and controlling a display to display the corrected image to be displayed. The first proportion can represent that the distribution condition of the brightness of the to-be-displayed image is in concentrated distribution or discrete distribution. Therefore, the contrast control curve of the to-be-displayed image can be corrected based on the first proportion, and then the contrast of the to-be-displayed image is corrected, so that the to-be-displayed images with different brightness distributions can obtain a better viewing effect.

Description
