Solution Overview
Problem
Current image processing technologies, such as MEMC, can cause distortion and poor display when applied to static images in a layered TV system, necessitating accurate detection of static layer information to control dynamic image processing effectively.
Innovation Solution
A method that determines the current topmost layer in a terminal's layer management module, obtains pixel values from a preset region, and compares them to a target value to identify the presence of image content, allowing for precise control of dynamic image processing.

Engineering Contradiction Analysis
1Reliability
If MEMC dynamic image processing technology is applied to TV images, then motion jitter and motion smear are eliminated and motion picture display is improved, but distortion and broken images are generated when static images are processed
Solution Approach 1:
The patent applies dynamics principle by making the image processing system adaptive and changeable based on content type. The system dynamically switches between MEMC processing and bypass modes depending on whether the current frame is identified as motion content or static content (such as OSD layers). This allows the processing pipeline to adjust its behavior in real-time, applying motion compensation only where needed while preserving static images without distortion.
Solution Approach 2:
The patent implements local quality principle by applying different processing treatments to different regions or layers of the image. Specifically, the system identifies static layers (such as OSD layers) and applies a different processing path compared to dynamic video layers. This localized approach ensures that static regions are preserved without MEMC processing while motion regions continue to benefit from it.
2Ease of operation
If the number of layers is used to determine whether OSD display or third-party application is turned on, then the detection method is simple, but the detection accuracy is insufficient to accurately identify static layers with image content
Solution Approach 1:
The patent replaces the mechanical counting method with an optical/image-based detection method. Instead of simply counting layers to determine if OSD or third-party applications are active, the system uses pixel value analysis and image content detection algorithms to identify whether a layer contains actual image content. This substitution of detection mechanism significantly improves accuracy while maintaining reasonable computational efficiency.
Solution Approach 2:
The patent introduces an intermediary detection layer that analyzes pixel values and image content characteristics between the raw layer data and the final detection result. This intermediary step involves comparing pixel values against reference values, detecting edge information, and analyzing image content to determine whether a layer is truly static or contains dynamic content. This intermediary analysis bridge the gap between simple layer counting and accurate content identification.

AI summary
Embodiments of present application relate to a method for detecting terminal static layer information, a terminal and a television. Based on the fact that a static layers in the terminal such as the OSD display layer and third-party application are managed as a whole by the terminal layer management module, this embodiment sets forth that: a current topmost layer is determined according to number information of each layer in a terminal layer management module; then a pixel value of a preset region in the topmost layer is obtained; analysis is performed on the pixel value in the preset region, and it is determined whether the pixel value of the preset region is different from a target pixel value. If the pixel value of the preset region is different from the target pixel value, then it is determined that there is image content in the topmost layer.
