Image Sensor Conditional Optical Correction Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image sensing apparatuses face operability degradation due to high arithmetic processing loads and difficulty in visually recognizing the effects of development processing, especially when dealing with optical system correction parameters, which require significant time and resource for processing.
Innovation Solution
The apparatus displays the effect of development processing only when it is visible, allowing for reduced arithmetic processing load by limiting optical system correction processing to specific conditions, such as when the image is displayed at a higher resolution on an external device or when the optical system correction parameter is not changed, thereby improving user interaction and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If development processing is executed for all parameters including optical system correction, then the completeness of image processing is improved, but the arithmetic processing load increases and operability degrades
Solution Approach 1:
The patent applies partial action by selectively executing optical system correction processing only when specific conditions are met (resolution threshold exceeded, parameter changed, or external display connected). This avoids performing unnecessary full processing while maintaining completeness when needed, thus resolving the contradiction between processing completeness and operability.
2Manufacturing precision
If optical system correction processing is performed, then the accuracy of image correction is improved, but the processing time increases
Solution Approach 1:
The patent implements dynamic processing by making the execution of optical system correction adaptive based on real-time conditions such as display resolution, parameter changes, and connection status. This dynamic approach ensures accurate correction is performed only when necessary, reducing unnecessary processing time while maintaining correction accuracy when required.
Solution Approach 2:
The patent changes the parameter of processing execution from static (always on) to conditional (based on resolution threshold, parameter change detection, and display connection status). This parameter change allows the system to balance correction accuracy with processing time efficiency by adjusting when correction is applied.
3Loss of information
If development processing result is always displayed, then the visibility of processing effect is improved, but the operability degrades due to constant processing load
Solution Approach 1:
The patent applies partial action by displaying the development processing result only when specific conditions are satisfied (resolution threshold exceeded, parameter changed, or external display connected). This selective display approach maintains visibility of processing effects when meaningful while avoiding constant display that would degrade operability through continuous processing load.

AI summary
An image sensing apparatus comprises image sensing means (301) capturing an object image, saving means (308) saving a captured image data, development processing means (307) reading out the image data and execute development processing for the image data to generate new image data, setting means (309,310) setting a parameter for the development processing, display means (309) displaying a development processing result and operation means (309,310) allowing a user to perform one of enlargement and reduction of the displayed image, wherein when a first parameter for which optical system correction processing is performed and a second parameter for which the correction processing is not performed are set, the development processing means executes development processing, to which the first parameter is applied, when a change to enlarged display is not made, and executes development processing, to which the first and second parameters are applied, when a change to enlarged display is made.
