Embodiment Construction

[0054] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0055] The invention provides a video playing control method. refer to figure 1, figure 1 It is a schematic flowchart of the first embodiment of the video playback control method of the present invention.

[0056] In this embodiment, the video playback control method includes:

[0057] Step S10, when the image of the video program played on the TV display interface is a non-high dynamic range HDR image, acquire the image to be processed of the current video program;

[0058] Wherein, the TV detects the image of the video program played on its display interface in real time, and when the detected image is a non-high dynamic range HDR image, acquires the image to be processed of the current video program. Preferably, in this embodiment, the TV can regularly acquire the images to be processed of the current video pro...

Abstract

The invention discloses a video playback control method, comprising: when the image of the video program played on the TV display interface is a non-high dynamic range HDR image, acquiring the image to be processed of the current video program; determining the gain value of the pixel point of the image to be processed Whether the preset condition is met; when the gain value of the pixel point of the image to be processed meets the preset condition, a transparent layer is added above the display layer of the image to be processed; sequentially obtain two adjacent pixel points whose gain value meets the preset condition The gain value of pixels; when the difference between the gain values ​​of two adjacent pixels obtained each time is greater than the first preset difference, based on the gain values, differences and coordinates of two adjacent pixels in the transparent Add pixels to the layer. The invention also discloses a video playing control device. The invention improves the image quality of non-HDR images and the definition of image color details, thereby improving the visual effect of users watching non-HDR video programs.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a video playback control method and device. Background technique [0002] At present, with the development of smart TVs, HDR (High-Dynamic Range, high dynamic range) technology is gradually applied to video programs, making the picture quality of smart TVs playing HDR video programs clearer. [0003] At present, there are still a large number of non-HDR video programs. Due to the low pixels of non-HDR video programs, when playing non-HDR video programs on smart TVs, the image quality of non-HDR video programs is poor, which affects viewing. Visual effects of the show. Contents of the invention [0004] The present invention provides a video playback control method and device, aiming to solve the technical problem of poor picture quality of non-HDR video programs played by smart TVs. [0005] In order to achieve the above object, the present invention provides...
