Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing measurement methods are used for stereo video format, then the measurement process is simple, but the measurement precision is insufficient leading to suboptimal display quality
Solution Approach 1:
The patent segments the stereo video signal analysis into distinct functional modules: an active space measuring circuit that analyzes pixel values to determine active space position, and a decision circuit that determines the stereo video format based on the measured position. This segmentation allows each module to specialize in specific measurement tasks, improving overall measurement precision while maintaining manageable system complexity through modular design.
2Reliability
If existing measurement methods are used for stereo video format, then the device structure is simple, but the viewing experience quality deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the active space measuring circuit continuously analyzes pixel values from the stereo video signal, determines the active space position, and provides this information to the decision circuit. The decision circuit then determines the appropriate stereo video format based on this feedback, ensuring reliable and accurate display quality adaptation to different video formats.
3Measurement precision
If existing measurement methods are used for stereo video format, then the system is easy to operate, but the measurement accuracy is insufficient
Solution Approach 1:
The patent enables the measuring apparatus to automatically analyze the stereo video signal without manual intervention. The active space measuring circuit autonomously examines pixel values to determine active space position, and the decision circuit automatically determines the stereo video format based on the measured data, eliminating the need for manual measurement while achieving high measurement accuracy.
