[0083] refer to figure 2 , figure 2 It is a flow chart of the first embodiment of the HDR film source playing method of the present invention. In this embodiment, the HDR film source playing method includes the following steps:

[0084] Step S10: Determine the state information of the color temperature control switch according to the currently opened application program;

[0085] Although most applications usually use D65 color temperature (color temperature is 6500K) to play HDR (High-Dynamic Range, high dynamic range image) source, but because the background or white picture is yellowish when playing HDR source at D65 color temperature, and For the color temperature requirements of some applications when playing HDR sources or for some customers’ color temperature requirements for HDR source playback, it is necessary to make the white screen displayed when playing HDR sources consistent with the white background of the OSD Logo as much as possible , at this time, when pl...

Abstract

The invention discloses a method for playing an HDR film source. The method comprises the following steps: determining state information of a color temperature control switch according to a currently opened application program; The application program plays the HDR film source; when the state information is in an off state, the HDR film source is played with the color temperature corresponding to the application program. The invention also discloses an HDR film source playing device and a computer-readable storage medium. The rapid switching of color temperature is controlled by the status information of the color temperature control switch to meet the color temperature requirements of different applications when playing HDR film sources.

Description

technical field [0001] The present invention relates to the field of image processing and display, in particular to an HDR film source playback method, device and computer-readable storage medium. Background technique [0002] Nowadays, the HDR film sources of most display devices and APPs generally use D65 color temperature for screen display. For example, Amazon’s Prime Video must pass the HDR10 quality certification and must be D65 color temperature. Usually, when playing an HDR source at a color temperature of D65, the overall background is warmer and yellowish. However, according to customer application requirements, some apps, such as Netflix, require that the white displayed under the HDR source be consistent with Netflix’s background white. When switching from Prime Video to Netflix, it is necessary to quickly convert the HDR color temperature to the color temperature of the screen itself. At present, when all APPs are in the same image mode, the software only calls...
