Image Processing Device Zoom Control via Ratio Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional imaging apparatuses require delicate zoom operations to maintain a desired imaging range, especially with changing subject distances, and are hindered by reduced button or lever sizes, making adjustments difficult.
Innovation Solution
An image processing device that calculates the ratio between a region of interest and a partial region within the image, controlling zoom power to match a predetermined value, allowing for simpler adjustment of the imaging range through user operations, including automatic zoom control and electronic enlargement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a delicate zoom operation is performed to maintain subject size when distance changes, then the subject size in imaging range is maintained, but the operation becomes complex and difficult
Solution Approach 1:
The imaging apparatus automatically adjusts the imaging range based on detected subject distance changes, eliminating the need for manual zoom operations. The system serves itself by autonomously maintaining subject size constancy through distance-based imaging range adjustment, resolving the contradiction between precision maintenance and operational simplicity
Solution Approach 2:
The apparatus continuously monitors subject distance and automatically adjusts imaging range in response to distance changes. This feedback mechanism ensures subject size remains constant without requiring delicate manual zoom operations, addressing both the precision maintenance and ease of operation requirements
2Volume of moving object
If the size of button or lever for zoom operation is reduced, then the apparatus size is reduced, but the adjustment of imaging range becomes difficult
Solution Approach 1:
The patent replaces mechanical zoom controls (buttons, levers) with an automatic control system that adjusts imaging range based on detected subject distance. This substitution eliminates the need for physically sized controls while maintaining or improving adjustment capability, resolving the contradiction between compact apparatus size and ease of operation
Solution Approach 2:
The system automatically adjusts imaging range without requiring user interaction with physical controls. This self-service approach eliminates dependency on button or lever size, allowing apparatus miniaturization while maintaining full imaging range adjustment functionality through autonomous distance-based control
