Electronic Device Image Compression Using Attribute Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electronic devices face inefficiencies in image compression and transmission due to the need for multiple compression processes, which increase resource allocation and time spent on compression, especially when transmitting high-quality images from a camera module to a processor or cloud server.
Innovation Solution
An electronic device that utilizes attribute information generated during primary image compression to perform secondary compression, allowing for efficient reuse of compression data to reduce the resource and time requirements for image processing and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple compression processes are performed on images, then image quality is maintained, but resource allocation and time spent on compression increase
Solution Approach 1:
The patent performs preliminary compression at the camera module using a first compression scheme before transmission to the processor. This preliminary action reduces the data size that needs to be transmitted and processed, while the attribute information generated during this preliminary compression is preserved and utilized in the secondary compression at the processor, avoiding redundant analysis and maintaining image quality.
2Manufacturing precision
If multiple compression processes are performed on images, then image quality is maintained, but time spent on compression increases
Solution Approach 1:
The patent implements a feedback mechanism where attribute information generated during the first compression at the camera module is transmitted along with the compressed image to the processor. This feedback allows the second compression to leverage previously analyzed characteristics of the image, avoiding redundant analysis and reducing the time required for secondary compression while maintaining image quality.
3Productivity
If attribute information is reused from primary compression for secondary compression, then resource requirements are reduced, but compression accuracy may be compromised
Solution Approach 1:
The patent applies different compression schemes (different parameter sets) at different stages: a first compression scheme is used at the camera module for preliminary compression, and a second compression scheme is used at the processor for final compression. The attribute information from the first compression is reused to guide the second compression, allowing resource-efficient processing while maintaining compression accuracy through scheme differentiation.
