Embodiment Construction

[0057] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0058] see figure 1 , is a flowchart of a video display method according to an embodiment of the present invention. The method can be applied to a video display device, and the video display device can be an electronic device with a specific video display function such as a mobile phone or a tablet. The method comprises the steps of:

[0059] First enter step S101 to acquire video frames to be displayed. The video frames include SDR video frames and HDR video frames. The luminance value range of SDR video frames is small, and usually the luminance value is below 100, which is easy to affect the user experience. Therefore, it is necessary to convert the video frames to HDR video frames to meet the sensory needs of users.

Abstract

The invention discloses a video display method and device, and the method comprises the following steps: firstly obtaining a to-be-displayed video frame which comprises an SDR video frame and an HDR video frame; enabling the obtained video frame to be converted into a video frame corresponding to the type of a display unit according to the type of the display unit; and finally displaying the converted video frame on the display unit. After the video frame is obtained, the method carries out the conversion of the video frame, and enables the video frame to be compatible with the current display unit, and then displays the video frame on the display unit, thereby enabling the same display unit to be compatible with the displaying of the SDR video frame and the HDR video frame, and bringing good sensual experience to a user.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a video display method and device. Background technique [0002] The current video decoding and display chips only support content in the brightness range of 0 to 100, while the brightness range that the human eye can perceive is 0 to 10,000, so there is a big difference between the effect of the video screen and the viewing effect of the human eye in reality. difference. Now the video production end can already support high dynamic range video from 0 to 1000, that is, HDR (High Dynamic Range) video, and current consumer-grade display devices can also support maximum brightness in the range of 200 to 500 due to the current video decoding and display chips. It does not support HDR video decoding and HDR content display processing, so users can only see videos with a maximum brightness of 100 when watching, which brings bad user experience to users.
