Abstract

The invention discloses an image compensation method and device. The method includes the following steps that: a perception model of an image is constructed according to a screen correlation coefficient, the brightness value of the image, the backlight brightness value and the perception brightness value of the image; a brightness compensation function of the image is obtained through calculation according to the perception model of the image; the brightness compensation function is adjusted according to the brightness mean value and the backlight brightness value of the image, so that an adjusted brightness compensation function can be obtained; and a brightness compensation value which is obtained through the adjusted brightness compensation function is utilized to perform compensation on the brightness of the image. The invention also discloses a corresponding image compensation device. With the image compensation method and device provided by the technical scheme of the invention adopted, power consumption can be saved with image compensation quality guaranteed.

Description

Technical field [0001] The invention relates to the field of image processing, and in particular to an image compensation method and device. Background technique [0002] Nowadays, with the popularization and application of handheld mobile devices, people have not only satisfied the functions such as calls and text messages provided by them, but also the needs of Internet, games, and applications have made the development of smart phones more rapid. However, the standby of smart phones Time is generally very limited, so the low-power design of handheld mobile devices has also become a primary issue. [0003] For the various liquid crystal display (LCD) screens of handheld mobile devices, TFT (Thin Film Transistor) screens have been widely used, and the power consumption of this screen under different devices accounts for 50% of the total system power consumption. %-80%. At the same time, in traditional LCD displays, the backlight size is usually set to the maximum brightness regar...
