Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If video compression is performed on high-quality video content, then power consumption and resource usage are reduced, but video quality may deteriorate
Solution Approach 1:
The patent applies preliminary action by generating metadata during image signal processing before compression occurs. This metadata contains attribute information about the target image that is used later during compression to maintain video quality. By preparing this information in advance, the system can perform compression with lower power consumption while preserving quality through informed compression decisions.
Solution Approach 2:
The patent uses metadata as an intermediary between the image signal processing and compression stages. This metadata acts as a mediator that carries attribute information from the original image through the compression process, enabling the compression algorithm to make quality-preserving decisions without requiring high computational resources during the actual compression operation.
2Manufacturing precision
If image resolution is increased to enhance video quality, then power consumption and bandwidth requirements increase
Solution Approach 1:
The patent extracts essential attribute information from high-resolution images during image signal processing and stores it as metadata. This extraction allows the system to work with compact metadata representations rather than full high-resolution image data during compression operations, significantly reducing power consumption while preserving the ability to maintain video quality through the extracted attributes.
3Quantity of substance
If video compression is performed to reduce data volume, then transmission bandwidth is reduced, but compression processing requires significant computing resources
Solution Approach 1:
The patent performs preliminary processing by generating metadata during image signal processing before compression. This advance preparation of attribute information simplifies the subsequent compression operation, as the compression algorithm can utilize pre-analyzed metadata rather than performing complex analysis during compression, thereby reducing the computing resources required for the actual compression task.
