Problems solved by technology

Since sub-pictures are superimposed on some areas of the main picture, the content of the main picture is actually incomplete at this time, which affects the viewing quality of the audience
[0004] Some improvement schemes to solve the above-mentioned defects adopt the method of adjusting and shielding the sub-picture, but this cannot provide the viewing effect of multiple pictures; The window moves or shrinks, but still obscures part of the main screen image, so the problem is not actually completely resolved
When viewers watch picture-in-picture, they still cannot watch the complete and high-quality main picture image

Embodiment 1

[0027] Embodiment 1, as shown in Figure 1, the method for adjusting the transparency of the picture-in-picture display, when the existing television set processes the picture-in-picture image display, the video signal represented as a sub-picture is converted into image data in digital RGB format and The ratio set by the sub-picture window is scaled and placed in the sub-picture memory.

[0028] On the basis of the determination of the sub-screen proportion and display position above, a weighting coefficient α set and input for the user is added, and the sub-screen RGB format data is converted and superimposed on the main screen data to achieve different displays. A blending display function for superimposed data with transparency.

[0029] As shown in Figure 2, input the video signal representing the main picture into the PW2300 chip, and convert it into image data in digital RGB format;

[0030] Input the video signal expressed as a sub-picture into the PW3400 chip, and con...

Abstract

The invention can modulate diaphaneity of PIP. It adopts the RGB style data of main picture and inner picture to be weighting coefficient transformed and outputs them from itself display window. The transformed inner picture is overlapped with main picture and the diaphaneity of the transformed inner picture is set adjustable. The inner picture has different diaphaneity to prevent main picture covered while viewer is watching. The approach works in the following steps: transferring main picture's video signal into RGB style image data that is memorized in main picture memorizer; transferring inner picture's signal into RGB style image data that is dwindled according to inner picture vision's setting proportion and then memorized in inner picture memorizer; transferring inner picture data and overlapping it on main picture data and the overlapped data is output onto the display screen to display the image after being overlapped.

Description

technical field [0001] The adjustment method of the invention realizes the transparency and mixed display functions of the sub-picture and the main picture. Background technique [0002] Existing televisions equipped with displaying picture-in-picture images usually reserve a sub-picture rectangular window at a certain vertical or horizontal position of the display screen, and the sub-picture images formed through compression are filled in this rectangular window to match the Home screens on the same or different channels are displayed simultaneously. [0003] A television set capable of displaying picture-in-picture images is based on providing multiple images simultaneously for multiple viewers to watch, or for viewers to simultaneously grasp the viewing conditions of two or more channels of TV programs. Since sub-pictures are superimposed on some areas of the main picture, the content of the main picture is actually incomplete at this time, which affects the viewing qual...
