Embodiment 1

[0048] figure 2 is a flowchart of a method for displaying screen content of a terminal device according to an embodiment of the present invention, as shown in figure 2 As shown, the method includes the following steps (step S202-step S230):

[0049] Step S202, initialization process. Initialize the resources related to OSD processing, apply for a cache area, and switch the refresh mode to OSD mode.

[0050] Step S204, message processing process. The received message is judged, if a video layer update instruction is received, step S206 is performed, if a graphic layer update instruction is received, step S228 is performed, if a message request for ending the OSD is received, the OSD mode is switched to normal model.

[0051] Step S206, read the pixels in the update area of ​​the video layer one by one.

[0052] Step S208, judge whether the pixel point is the key color according to the pixel value of the graphic layer of the pixel point, if yes, execute step S212, if not,...

Abstract

The invention discloses a screen content display method and a screen content display device. The screen content display method includes a first step of receiving an updating instruction sent by a user and confirming an updated area according to the updating instruction, a second step of reading pixel points in the updated area one by one, wherein the upper layer of the pixel points is a image layer and the lower layer of the pixel points is a video layer, a third step of configuring the transparency of the image layer of the pixel points according to the pixel value of the image layer of the pixel points for the pixel points which are read, mixing the pixel value of the video layer of the pixel points with the pixel value of the image layer when the transparency value is bigger than 0 and smaller than 255, and storing a mixed result to a corresponding position of a cache region, and a fourth step of displaying the pixel values stored in the cache region on a screen. Through adoption of the screen content display method, the problem in the prior art that calculated amount of screen contents is large in the displaying process is solved. Consequently, calculation procedures are simplified, power consumption of the device is reduced and user experience is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for displaying screen content. Background technique [0002] With the development of electronic technology and software technology, the popularity of portable terminal devices such as mobile phones, MP4, and tablet computers is getting higher and higher. When people choose these devices, they also pay more and more attention to their multimedia processing capabilities and screen display effects. . Smooth high-definition video playback effects and gorgeous and changeable user interface (User Interface, referred to as UI for short) special effect display become an important factor to attract customers' attention and stimulate customers' desire to buy. [0003] Multimedia playback and UI special effects must be multi-layer superimposed on the screen menu adjustment method (On-Screen Display, referred to as OSD). OSD is actually a method and technology for disp...
