Image Capture Noise Control via Automatic Parameter Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image capturing methods require users to adjust parameters manually to achieve uniform noise levels, which is time-consuming and effort-intensive, especially when the scene or camera conditions change.
Innovation Solution
An information processing apparatus that allows users to set a desired noise level, automatically determining and adjusting image capturing conditions such as ISO speed, shutter speed, and aperture to achieve the target noise amount, using a control unit with a noise amount specifying unit and an image capturing parameter determination unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If users manually adjust image capturing parameters to achieve uniform noise levels, then image quality consistency is improved, but user time and effort increase
Solution Approach 1:
The image capturing apparatus automatically determines and adjusts image capturing parameters (ISO speed, shutter speed, aperture) based on the captured image characteristics and user-specified noise amount, enabling the system to self-regulate noise levels without requiring manual user intervention for each scene change
Solution Approach 2:
The system calculates the noise amount from the captured image and compares it with the user-specified target noise amount, then automatically adjusts the image capturing parameters based on this feedback loop to achieve the desired noise level consistency across different scenes
2Manufacturing precision
If image capturing parameters are changed to adapt to different scenes, then image quality is improved, but noise amount uniformity deteriorates
Solution Approach 1:
The system dynamically changes image capturing parameters (ISO speed, shutter speed, aperture) based on the relationship between the calculated noise amount and the user-specified target noise amount, allowing the apparatus to adapt to different scenes while maintaining uniform noise levels across varying image quality requirements
3Manufacturing precision
If users adjust parameters for each scene change, then desired noise level is achieved, but operation complexity increases
Solution Approach 1:
The apparatus performs automatic noise amount calculation and parameter adjustment based on user-specified target noise levels, eliminating the need for users to manually adjust parameters for each scene while maintaining precise noise level control through the system's self-regulating mechanism
