[0004] However, since the image displayed by the second terminal is an image synthesized by the OSD menu and the video frame image, when the second terminal processes the image quality of the synthesized image, it may also process the part of the OSD menu, thereby The OSD menu is distorted and cannot be displayed normally. Therefore, there is an urgent need for a method for determining the area of the OSD menu so that the display area of the OSD menu can be avoided during image quality processing, thereby avoiding the distortion of the OSD menu.

Embodiment Construction
[0066] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0067] An embodiment of the present invention provides a method for determining an OSD menu area in a terminal playing an external video, wherein the terminal playing an external video may be a terminal such as a smart TV or a computer, see Figure 1A , the method includes:
[0068] Step 101: From the current frame image, determine a first set of pixel points, the first set of pixel points includes pixels satisfying preset conditions.
[0069] Among them, for each pixel point in the current frame image, the terminal first judges whether the pixel point satisfies the preset condition, and then selects the pixel point satisfying the preset condition from the current frame image, and converts the pixels composed of the selected pixel point...

The present invention, which belongs to the technical field of display, discloses a method and apparatus for confirming an OSD menu area in a terminal for playing an external video. The method comprises: a first pixel set which includes pixels satisfying the preset condition is confirmed from the current frame image; pixels at the same positions as OSD pixels are selected from the first pixel set to obtain a second pixel set, wherein the OSD pixels are the pixels in OSD menu areas in multiple continuous images before the current frame image; and the OSD menu area in the current frame image is confirmed based on the pixels in the second pixel set. The method can be used to confirm the OSD menu area based on the second pixel set after the first and second pixel sets are confirmed. Therefore, when the image is processed, only the area out of the OSD menu area is needed to be processed, the distortion of an OSD menu can be avoided and the OSD menu can be displayed normally.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a method and device for determining an OSD menu area in a terminal playing external video. Background technique [0002] With the rapid development of display technology, terminals have more and more display functions. For example, people can connect a TV to a computer or a set-top box, and watch videos in the computer or videos transmitted by the set-top box through the TV. In the process of watching a video, people can also set display properties such as brightness or contrast through the OSD (On Screen Display) menu of the computer or set-top box, and change channels, etc. At this time, the video and the OSD menu can be displayed on the TV at the same time. . [0003] For ease of description, a terminal such as a computer or a set-top box for transmitting video is referred to as a first terminal, and a terminal for playing video such as a TV is referred to as a second termin...
