Embodiment 1

[0077] A method for displaying an image provided by the embodiment of the present application will be described in further detail below in conjunction with the accompanying drawings. The specific implementation of the method may include the following steps (the method flow is as follows: figure 2 shown):

[0078] Step 201, receiving an input image, dividing the image into a plurality of first sub-regions, and calculating an average value of brightness corresponding to each first sub-region.

[0079] After receiving the input image, first, the image is partitioned according to the number of partitions of the LED backlight, that is, the image is divided into a plurality of first sub-regions, for example, generally more divisions are 32*32 regions, the minimum It also supports 300 areas, and then calculates the average value of the brightness corresponding to each first sub-area, wherein there are many ways to calculate the average value of brightness corresponding to each first...

Embodiment 2

[0115] An embodiment of the present application provides an image display device, see Figure 4 , the device consists of:

[0116] A partitioning unit 401, configured to receive an input image, divide the image into a plurality of first sub-regions, and respectively calculate the average value of brightness corresponding to each first sub-region;

[0117] A first determining unit 402, configured to determine at least one second sub-region whose average brightness value is smaller than a preset brightness threshold from the plurality of first sub-regions;

[0118] The second determining unit 403 is configured to determine each of the second sub-regions based on the preset starting control depth, the preset brightness threshold and the average value of the brightness corresponding to each second sub-region in the at least one second sub-region. A correlation factor corresponding to the two sub-regions, wherein the correlation factor represents the brightness value compensation ...

Embodiment 3

[0142] The application provides an electronic device, see Figure 5 , the electronic device comprising:

[0143] Memory 501, configured to store instructions executed by at least one processor;

[0144] The processor 502 is configured to load and execute instructions stored in the memory, so as to implement the method described in Embodiment 1.

Abstract

The invention discloses an image display method and device, and the method comprises the steps: receiving an input image, dividing the image into a plurality of first subareas, and respectively calculating the average value of brightness corresponding to each first subarea; determining at least one second sub-region from the plurality of first sub-regions, wherein the average value of the brightness of the second sub-region is smaller than a preset brightness threshold value; determining an association factor corresponding to each second sub-region based on a preset start control depth, a preset brightness threshold and an average value of brightness corresponding to each second sub-region in the at least one second sub-region; compensating the average value of the brightness correspondingto each second sub-region based on the correlation factor to obtain a compensated brightness value; and adjusting the backlight value corresponding to each second sub-region based on the compensatedbrightness value, and displaying the image based on the adjusted backlight value. The technical problem that in the prior art, image display effect is poor is solved.

Description

technical field [0001] The present application relates to the technical field of image display, and in particular to an image display method and device. Background technique [0002] Liquid Crystal Display (LCD) is widely used in home appliances, mobile, monitoring, airborne and aviation equipment, etc., and occupies a dominant position in flat panel display devices. However, the traditional LCD has the disadvantages of low energy consumption and low contrast ratio, resulting in poor display effect of the liquid crystal display. In order to improve the energy efficiency and contrast of the liquid crystal display, usually by adjusting the display brightness of the display, the contrast between the darkest area and the brightest area in the image is enhanced to enrich the layers in the image. [0003] At present, in liquid crystal displays, the technology for enhancing the contrast is mainly the area backlight technology. Among them, the area backlight technology mainly inclu...
