Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems face challenges in stabilizing the transmission of high-resolution and high-frame-rate image data across interfaces with different protocols, while minimizing power consumption, electromagnetic noise, and cable routing difficulties.
Innovation Solution
The system employs a compression section to compress image data before transmission, a relay section that transmits the compressed data without decompression across interfaces with different protocols, and a display section that decompresses and displays the image data, thereby minimizing data loss and processing delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the bit width is expanded or bit rate is increased to transmit large-size data at high speed, then the image resolution and frame rate are improved, but power consumption and electromagnetic noise increase
Solution Approach 1:
The patent applies preliminary compression action at the image generation apparatus before transmission. By compressing the image data in advance using schemes such as variable length encoding or sub-sampling, the data size is reduced before it enters the transmission path, thereby allowing high-resolution images to be transmitted at lower bit rates and reducing power consumption in the display apparatus.
Solution Approach 2:
The patent introduces a compression scheme as an intermediary mechanism between the image generation apparatus and display apparatus. This intermediary compression process enables efficient data representation that can be transmitted over interfaces with limited bandwidth without requiring high power consumption for data transmission and processing.

Solution Approach 2:
The patent introduces a compression scheme as an intermediary mechanism that enables efficient data transmission. This intermediary process reduces the overall data volume that must be transmitted at high speeds, thereby reducing electromagnetic noise while maintaining high frame rates.
3Adaptability or versatility
If compression and decompression are performed at multiple interfaces with different protocols, then data compatibility is improved, but image quality deteriorates and processing time increases
Solution Approach 1:
The patent performs the compression action in advance at the image generation apparatus, before the data enters the complex multi-interface transmission path. This preliminary compression ensures that only essential image information is transmitted, reducing the impact of potential quality losses during protocol conversions while maintaining interface compatibility.
Solution Approach 2:
The patent maintains continuous useful action by ensuring that the compressed data format is preserved throughout the transmission path across different interfaces. By avoiding repeated compression and decompression cycles at each interface, the system maintains image quality while achieving protocol compatibility through the relay section.

AI summary
A content processing apparatus compresses image data of content in a lossy manner and transmits the image data to a head-mounted display through an interface. An image processing integrated circuit of the head-mounted display transmits the image data to a display panel through an interface whose protocol is different from a protocol of the interface, without decoding and decompressing the image data. The display panel displays the image that has been decoded and decompressed after being transmitted through the interface.
