Problems solved by technology

[0008] The essence of the above two methods is to ensure that the content on the screen can be clearly displayed when using the preset picture at the factory to switch the background, so the above two methods can only ensure that the content on the screen can be clearly displayed when using the preset picture ; However, if the user is using a downloaded picture or a picture taken by a camera, it cannot guarantee that the content on the screen can be displayed clearly, so it cannot meet the needs of end users for personalized display

Embodiment 1

[0043] Such as figure 1 As shown, the processing process of displaying superimposed graphics on the background screen in the embodiment of the present invention is as follows:

[0044] Step 110, determine the area occupied by the superimposed graphics. This step may specifically include:

[0045] (1) Obtain the position of the superimposed graphics on the background image or screen.

[0046] The position coordinates of the pixel at the upper left corner of the superimposed graphic on the background picture or terminal screen may be used as the position of the superimposed graphic on the background picture or terminal screen.

[0047] (2) Determine the height and width of the superimposed graphics, and determine the superimposed area occupied by the superimposed graphics according to the position, height and width of the superimposed graphics.

[0048] If the superimposed graphic is a picture (may include images, menus, text boxes, etc.), the height and width of the picture ...

Embodiment 2

[0117] In this embodiment, the value of the color feature value of the background picture in the superimposition area is not taken as the color feature value of the superimposed graphic, but the color coding value of each pixel of the background picture in the superimposition area is reversed bit by bit. The value of is used as the color-coded value of the corresponding pixel of the overlay graphic.

[0118] Such as Figure 7 Shown is the processing process of displaying superimposed graphics on the background screen in this embodiment, Figure 7 middle:

[0119] Step 710, determine the superimposed area occupied by the superimposed graphics. Same as step 110 in Embodiment 1.

[0120] Step 720, acquire the color coded value of each pixel of the background image in the superimposed area, and perform color shift transformation on the color coded value.

[0121] Step 720, acquiring the position of each pixel of the superimposed graphic, using the transformed color coded value...

Abstract

The invention provides a method and a device for displaying overlaid graphs on a background picture. The method comprises the following steps: determining overlaid districts of the overlaid graphs; calculating color characteristic values of the background picture in the overlaid districts according to color coding values of pixels in the overlaid districts; performing color offset and change to the color characteristic values; taking the characteristic values of the switched color characteristic values as the characteristic values of the overlaid graphs in the overlaid districts; and drawing and displaying the overlaid graphs. The embodiment of the invention can ensure that information which is permanently displayed on a terminal is identified clearly by customers under various backgrounds.

Description

technical field [0001] The invention relates to graphic display technology, in particular to a method and a display device for displaying superimposed graphics on a background picture. Background technique [0002] At present, most terminals can freely set the background screen, and can place some superimposed graphics (including text, pictures, etc., and pictures can include images, menus, text boxes and other graphics, etc.) on the background screen according to the needs of functions. When displaying text or pictures on a background image, the text and pictures are actually superimposed on the background image, that is, the text font and other pixels outside the picture outline are set to a transparent color, while the font and picture outline It itself covers the corresponding pixels on the background image. [0003] The so-called transparent color of a pixel means that when a pixel A is overlaid on a pixel B, if the pixel A has a transparent color value, a new RGB colo...
