Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image transmission techniques face challenges in transmitting images over low bandwidth communication due to high data processing demands and compression rate limitations, which can result in increased power consumption and failed transmissions, especially when preview images are required without maintaining original image quality.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If image compression is applied to transmit images over low bandwidth communication, then transmission capacity is improved, but power consumption increases due to large amount of data processing
Solution Approach 1:
The patent extracts only the essential features from the original image - specifically contour information and color information - while discarding redundant detail data. This extraction approach reduces the data volume significantly for preview images while maintaining the core visual characteristics needed for user recognition and communication.
Solution Approach 2:
The patent segments the image processing into distinct functional components: contour extraction, color information extraction, and selective encoding. By dividing the complex image processing task into separate modules, the system can optimize each component independently to achieve better compression efficiency with lower processing power consumption.
2Quantity of substance
If image compression is applied to transmit images over low bandwidth communication, then data size is reduced, but transmission reliability deteriorates when compression rate exceeds the limited compression rate
Solution Approach 1:
The patent changes the fundamental parameters of image representation by switching from pixel-based compression to feature-based compression. By transforming the image into contour and color information representations, the system achieves higher effective compression ratios that adapt to low bandwidth constraints while maintaining transmission reliability through selective feature preservation.
Solution Approach 2:
The patent applies partial compression by selectively encoding only the most important image features (contours and dominant colors) rather than compressing the entire image data. This partial action approach ensures that critical visual information is preserved while discarding less important details, maintaining transmission reliability under strict bandwidth limits.
3Quantity of substance
If preview image transmission is implemented without maintaining original image quality, then data size is reduced for efficient transmission, but image quality deteriorates
Solution Approach 1:
The patent creates a simplified copy of the original image that retains the essential structural and color information through contour and color data representation. This copy approach allows for efficient transmission of preview images while maintaining sufficient visual fidelity for the intended purpose of user review and communication.
Solution Approach 2:
The patent applies different quality levels to different aspects of the image: high fidelity is maintained for contour information and dominant color representation, while detailed pixel information is discarded. This local quality differentiation ensures that the most visually important elements are preserved at high quality while reducing overall data size for efficient transmission.

AI summary
A method of transmitting an image is performed by a first device and includes obtaining an image including an object, obtaining, based on a preset setting condition of the first device, contour information defining a contour of the object and color information about a color of the object, and transmitting the contour information and the color information to a second device.
