Embodiment 1

[0035] Embodiment one, figure 1 It is a flow chart of the custom screen brightness subroutine, which specifically includes the following steps:

[0036] S101. Determine whether the user activates the screen brightness custom setting function, if yes, execute the subsequent steps, otherwise, exit the subroutine.

[0037] S102. Provide a reference picture to the user, and adjust the brightness of the reference picture in real time according to a brightness adjustment instruction sent by the user.

[0038] Here, the reference picture may be a static uniform white picture, or a static color picture.

[0039] S103. Determine the brightness reference value Y0, and write it into the internal memory of the display device for storage.

[0040] That is, when the user stops performing the brightness adjustment operation, the brightness average value of the entire reference frame is the brightness reference value Y0.

[0041]Here, if the reference picture is a static uniform white pict...

Abstract

The invention discloses a screen brightness adjustment method and a television, wherein, the adjustment method comprises the following steps: a. carrying out brightness adjustment on account of the reference screen provided by a display device to determine the brightness reference value Y0; b. comparing the brightness average value Y of each screen with the brightness reference value Y0 when the display device displays video programs normally; if Y0-delta Y<=Y<=Y0+delta Y, then carrying out no adjustment on the brightness of the current screen; if not, adjusting the brightness average value ofthe current screen to be Y0 from Y, wherein, delta Y is the allowable error value; and c. displaying the current screen. The screen brightness adjustment method in the invention can ensure that the screen brightness value can be automatically adjusted according to screen content by the display device, thus ensuring that the screen brightness of the video programs is in an extent in which users feel comfortable all the time in the playing process, not only avoiding the trivial manual adjustment process, but also ensuring more accurate adjustment effects, and in particular being applicable to promotion and application in television products.

Description

technical field [0001] The invention belongs to the technical field of display control, and in particular relates to an automatic adjustment method of screen display brightness and a television set designed by adopting the screen brightness adjustment method. Background technique [0002] The quality of images displayed by televisions and other display devices is closely related to people's perception, and ambient light has a great influence on people's perception. For example, in the case of strong outdoor ambient light during the day, the display device needs a very bright display effect to allow users to clearly identify the displayed content; and in the case of dark ambient light at night, if the display brightness is too strong, it will make people feel uncomfortable. very harsh. Therefore, it is very important for a user to adjust a display device to work at an appropriate display brightness. [0003] Most of the methods for adjusting the display brightness of the ex...
