Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Solid-state imaging apparatuses with multi-plate type image sensors generate large amounts of data, requiring data thinning to reduce transmission bandwidth, but existing methods do not effectively manage thinning rates for different color components, potentially degrading image quality.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multi-plate type image sensor is used to generate multiple pieces of image data with different color components, then image quality and color information are improved, but data amount increases requiring complex thinning processing
Solution Approach 1:
The patent segments the thinning processing by color component type (R, G, B). Different thinning rates are applied to different color components based on their respective characteristics and the operation mode. This allows selective retention of important color data while reducing overall data volume, resolving the contradiction between maintaining image quality and reducing data amount.
Solution Approach 2:
The patent applies different thinning rates to different color components (local quality) rather than uniform thinning. For example, in movie mode, G component may be thinned at a different rate than R or B components. This localized approach maintains critical color information while reducing total data volume, addressing both image quality and data amount requirements.
2Productivity
If thinning processing is applied to reduce data transmission band, then data transmission efficiency is improved, but image quality may be degraded
Solution Approach 1:
The patent implements dynamic thinning rate adjustment based on operation mode. The thinning rate setting unit changes thinning rates according to whether the device is in still image mode, movie mode, or other modes. This dynamic approach optimizes the balance between transmission efficiency and image quality for each specific operating condition.
Solution Approach 2:
The patent changes the parameter of thinning rate based on operation mode and color component type. By adjusting this parameter dynamically, the system achieves optimal data transmission efficiency while preserving sufficient image quality information. The thinning rate becomes a controllable variable that adapts to different operational requirements.
