Imaging Apparatus Subject Change Detection for Manual Focus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses face challenges in improving operability during manual focus adjustment, as the current method of manually selecting the position to be magnified is complex and time-consuming.
Innovation Solution
An imaging apparatus that extracts multiple subjects from moving image data and automatically switches between different magnification modes based on changes in the subjects, allowing for improved user interaction during manual focus adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual magnification selection is implemented, then focus adjustment precision is improved, but operability deteriorates
Solution Approach 1:
The system automatically detects subject changes and switches magnification displays without user intervention. The imaging apparatus monitors the captured images, identifies when subjects change, and autonomously updates the magnification region to focus on the new subject, eliminating the need for manual magnification selection while maintaining precise focus adjustment.
Solution Approach 2:
The system continuously monitors captured images for subject changes and uses this feedback to automatically adjust the magnification display. When a subject change is detected through image analysis, the system responds by switching the magnification region, creating a closed-loop control system that adapts to changing scenes without user input.
2Productivity
If automatic subject change detection is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent replaces manual mechanical operation with automated image processing. Instead of requiring users to manually select and adjust magnification regions, the system uses computer vision algorithms to automatically detect subject changes in captured images and switches magnification displays accordingly, substituting mechanical user interaction with automated digital processing.

AI summary
Provided are an imaging apparatus, an image processing method, and an image processing program capable of improving operability in a case in which manual focus adjustment is performed. Processing of extracting a plurality of subjects from moving image data obtained by imaging is performed, first moving image data in which a region including a specific subject among the plurality of subjects is magnified is output to a display destination, and, in a case in which a change has occurred in any of the plurality of subjects in the moving image data, second moving image data in which a region of each of the plurality of subjects is magnified is output to the display destination instead of the first moving image data, and then, in a case in which an instruction to select the subject is given, third moving image data in which a region including a selected subject is magnified is output to the display destination instead of the second moving image data.
