Digital Camera Image Processing Intent Judgment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital cameras often produce images with unintended processing due to erroneous photography mode settings, leading to suboptimal image quality when further image processing is applied, as existing methods fail to accurately determine if image processing was intentionally set by the user.
Innovation Solution
An image processing apparatus and method that reads image data with attached processing information, judges whether the processing was intentionally set, and adjusts further processing accordingly, either canceling or reducing existing processing if unintended, to ensure optimal image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If further image processing is performed on image data that has already undergone image processing, then image quality may be improved through additional processing, but the original intended image quality may be degraded due to unintended processing accumulation
Solution Approach 1:
The system performs preliminary analysis of photography information (mode settings, scene conditions) before executing further image processing. By checking the photography mode and processing history in advance, the system determines whether additional processing is actually needed, preventing unnecessary processing that would degrade image quality while allowing beneficial processing to proceed.
2Reliability
If image processing is cancelled or reduced based on photography mode information, then unintended processing can be prevented, but processing that should have been applied may be incorrectly cancelled
Solution Approach 1:
The system uses feedback from multiple sources including photography mode information, scene analysis results, and processing history to make intelligent decisions about whether to apply or cancel processing. The feedback loop continuously evaluates whether the current processing aligns with user intent and image requirements, allowing the system to correct erroneous mode settings while preserving intended processing.
Solution Approach 2:
The system introduces an intermediary analysis layer that sits between the photography mode information and the image processing execution. This intermediary layer analyzes both the mode settings and the actual image content to determine the true user intent, acting as a mediator that can override erroneous mode settings while preserving legitimate processing requirements.
3Extent of automation
If photography mode information is used to control image processing, then processing can be automated, but the complexity of determining user intent increases
Solution Approach 1:
The system creates a universal processing control mechanism that handles multiple photography modes and processing types through a single integrated framework. Rather than creating separate control logic for each mode, the system uses a unified approach that analyzes photography information and determines appropriate processing actions, reducing overall system complexity while maintaining high automation capability.
Data Source
AI summary
Image data on which image processing has already been performed is obtained with a digital camera. Image processing information includes information indicating a photography mode set at the digital camera. Tag information including the image processing information is attached to the image data. If the image processing information includes information indicating a night view mode, an image output device judges whether the night view mode was intentionally set by a user by judging whether photography date/time information included in the tag information represents night. If the judgment is YES, the image output device sets an output image processing means not to perform exposure correction processing. If the judgment is NO, the image output device sets the output image processing means to perform regular processing including the exposure correction processing.
