Color Temperature Detection via Alpha Channel Embedding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for detecting color temperature adjustment in GPUs face inaccuracies due to ineffective capture of changes in image color temperature during transmission, leading to errors in detected color temperature values.
Innovation Solution
A method and apparatus that convert the actual used color temperature into a target matrix, embed it into a video frame, and transmit it to another terminal for accurate parsing, allowing for precise detection of color temperature adjustment effects by comparing the actual used, rendered, and standard color temperatures.

Engineering Contradiction Analysis
1Ease of operation
If the image is transmitted to the master in a manner such as a desktop screenshot, then the transmission is simple and straightforward, but the change in the color temperature of the image in the slave cannot be effectively captured, resulting in an error in a detected color temperature value
Solution Approach 1:
The patent introduces an intermediary mechanism by embedding color temperature data into a specific color channel (alpha channel or unused color channel) of the image transmission. This allows the color temperature information to be carried along with the image without requiring separate transmission channels, thus maintaining transmission simplicity while improving detection accuracy.
Solution Approach 2:
The patent embeds the color temperature data within the image structure itself, nesting the temperature information inside the image's color channels. This nested approach allows the color temperature to be transmitted as part of the image data without increasing overall transmission complexity, resolving the contradiction between simple transmission and accurate detection.
2Ease of manufacture
If conventional screenshot transmission is used, then the implementation is straightforward, but the color temperature adjustment effect cannot be accurately detected
Solution Approach 1:
The patent changes the parameter representation by encoding color temperature values into specific color channels of the image. Instead of transmitting color temperature as a separate parameter, it is transformed into visual data within the image's color space, allowing accurate detection while maintaining straightforward implementation through existing image transmission protocols.
3Measurement precision
If color temperature data is embedded into image channels, then detection accuracy is improved, but the data transmission requires more complex processing
Solution Approach 1:
The patent implements self-service by having the slave terminal automatically embed the color temperature data into the image channels without requiring additional intervention from the master terminal or external systems. The embedding process uses the slave's own rendering pipeline to incorporate the temperature data, reducing overall system complexity despite the enhanced detection capability.

AI summary
The present disclosure relates to a color temperature adjustment effect detection method and apparatus, a computer device, a storage medium, and a computer program product. A second terminal sends a real standard color temperature to a first terminal, so that the first terminal acquires an actual used color temperature based on the real standard color temperature. Through the first terminal, the actual used color temperature is converted into a target matrix, and the target matrix is embedded into a video frame to obtain an embedded image. Through the first terminal, the embedded image is displayed based on the actual used color temperature, and the embedded image is sent to the second terminal, so that the second terminal parses the embedded image to obtain the actual used color temperature, and acquires an actual rendered color temperature based on a display result of the first terminal.
