Embodiment Construction

[0020] Such as figure 1 As shown, one of the screen data processing methods of synchronously generating an embedded small screen on the display screen of the present invention starts at step S101, and then at step S102, it is judged whether the small screen is turned on or not?

[0021] When the judgment result of step S102 is yes, the process proceeds to step S103; otherwise, the process proceeds to step S104.

[0022] In step S103, create a memory space for off-screen rendering: off-screen FBO.

[0023] In step S104, each application layer Layer 1, Layer 2, . . . , Layer n is directly synthesized into the FrameBuffer of the video memory.

[0024] After step S103, the process proceeds to step S105; and after step S104, the process proceeds to step S111.

[0025] In step S105, the rendering output of the screen data is changed to the off-screen FBO, and the screen data is the image data of each application layer Layer 1, Layer 2, ..., Layer n.

[0026] In step S106, a full-...

Abstract

A screen data processing method enabling an embedded type small screen to be synchronously generated on a display screen is characterized by comprising the following steps that if the small screens are switched on, memory space off-screen FBO for off-screen rendering is created; screen data are rendered and output to the off-screen FBO in an orientation changing mode; an entire screen layer Layer n+1 and a small screen layer Layer n+2 are created and share texture; the texture of the small screen layer Layer n+2 is connected to the off-screen FBO; all application layers Layer 1, Layer 2, ..., Layer n are synthesized to the off-screen FBO, namely the memory space of the small screen layer Layer n+2; the screen data are rendered and output to a video memory Frame Buffer in an orientation recovery mode, and the off-screen FBO is destroyed; the entire screen layer Layer n+1 and the small screen layer Layer n+2 are combined to the video memory Frame Buffer; Buffer spaces are exchanged; data of the combined entire screen layer Layer n+1 and the small screen layer Layer n+2 are sent to the display screen to be displayed. By means of the method, synchronous display of data on the entire screen (large screen) and data on the small screen can be achieved, and the smooth and perfect experience with data on the large screen and data on the small screen being synchronous is achieved.

Description

Technical field: [0001] The invention relates to a screen data processing method for synchronously generating an embedded small screen on a display screen. Background technique: [0002] Nowadays, the size of the touch screen of mobile handheld devices is getting bigger and bigger. In many occasions, it is necessary to use the built-in shrink screen, such as one-handed operation. control the small screen area, and then operate the small screen, so as to meet the needs of controlling the entire large screen area. [0003] So how to generate an embedded small screen? The common and simple method is: periodically capture the image data of the entire screen (large screen), extract some points or shrink the screenshot and fill it into the small screen area. The disadvantages of this method are: ① the data on the small screen is not synchronized with the data on the whole screen (big screen); Frame rate, manifested as stuttering. These two shortcomings lead to poor experience ...
