Problems solved by technology

If the processing capability of the terminal CPU is limited, and the data volume of each frame of video data is large and the difference between each frame of video data is also large, the scanning frame rate of the CPU in the progressive scan mode will be very low, which will cause the terminal display The video screen of the terminal is unclear, which reduces the quality of the terminal video screen display

Embodiment Construction

[0022] The technical solutions of the embodiments of the present invention will be described in further detail below with reference to the drawings and embodiments.

[0023] figure 1 A flow chart of a video data processing method provided by Embodiment 1 of the present invention, such as figure 1 As shown, the method includes:

[0024] Step 101, receiving current frame video data;

[0025] Step 102, generating the difference value between the current frame video data and the previous frame video data;

[0026] Step 103 , when it is determined that the difference value is greater than or equal to the set threshold, perform interlaced scanning on the video data of the current frame, and scan the video data of the current frame to the display device.

[0027] In this embodiment, when it is determined that the difference between the current frame video data and the previous frame video data is greater than or equal to the set threshold, the current frame data is interlaced, the...

Abstract

The embodiment of the invention discloses a video data processing method, a central processing unit (CPU) and a terminal. The method comprises the following steps of: receiving current frame video data; generating a difference of the current frame video data and the previous frame video data; and when the difference is greater than or equal to a set threshold value is judged, performing interlaced scanning on the current frame video data to scan the current frame video data to a display device. According to the technical scheme of the embodiment of the invention, on the premise that the processing capacity of the CPU is limited, the interlaced scanning mode is adopted when the difference of the current frame video data and the previous frame video data is great so as to improve the scanning frame rate, avoid the condition that the video display picture is not clear and improve the display quality of the terminal video picture.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to a video data processing method, a central processing unit and a terminal. Background technique [0002] With the development of various terminals, more and more terminals are equipped with video processing functions, including video playback or video preview. At present, the method for processing video data by a terminal is to sequentially scan each frame of video data by the CPU sequentially, and display the scanned video data by a display device. With the increasing size of video data and the increasing requirements of users for video playback and video preview, video data is processed in a progressive scanning manner, and the central processing unit (Central Processing Unit, hereinafter referred to as: CPU) processing capacity requirements are also getting higher. If the processing capability of the terminal CPU is limited, and the data volume of each frame of video...
