Imaging Apparatus Scene Recognition Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses are inefficient in recognizing and adapting to changing photographic scenes, as they perform scene recognition processing continuously and lack stable mode settings for dynamic environments.
Innovation Solution
An imaging apparatus equipped with an information acquiring device, reference information registering device, scene change determining device, and scene recognizing device, which acquires and updates photographic information, determines scene changes, and adjusts settings such as display, photography, and signal processing based on recognized scene changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If photographic mode check processing is always in working condition, then scene recognition accuracy is maintained, but processing efficiency deteriorates
Solution Approach 1:
The patent implements periodic scene recognition processing triggered by specific events (shutter release, mode switching, scene change detection) rather than continuous processing. The control unit determines whether scene recognition is necessary based on whether photographic conditions have changed, enabling the system to maintain accuracy when needed while improving efficiency by skipping unnecessary processing cycles.
2Speed
If photographic mode autoconfiguration is performed only once after shutter button is pressed halfway, then processing speed is improved, but scene recognition stability deteriorates
Solution Approach 1:
The patent employs feedback mechanisms where the control unit continuously monitors whether photographic conditions have changed (such as subject distance, brightness, or composition changes) and triggers scene recognition processing when changes are detected. This feedback loop ensures stable and accurate scene recognition throughout the photography process while maintaining efficient processing by only activating when necessary.
3Measurement precision
If scene recognition processing is performed continuously, then scene change detection accuracy is improved, but energy consumption increases
Solution Approach 1:
The control unit determines scene recognition necessity based on whether photographic conditions have changed, triggering processing only when changes are detected rather than continuously. This event-driven periodic processing maintains accurate scene change detection while significantly reducing energy consumption by keeping the processing unit idle during stable conditions.

AI summary
To output stable results as necessary when recognizing scenes with a camera. Unless the result of scene recognition can be stabilized, an output result will confuse the user. In consideration thereof, by combiningly performing processing for determining what type of scene a particular scene is and processing for monitoring whether or not a change has occurred from a recognized scene, it is now possible to perform scene recognition in an accurate and stable manner.
