Imaging Apparatus Processor Dynamic Movable Range Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses face limitations in image shake correction performance, particularly when switching between normal and crop recording modes, where the movable range of the imaging element or lens needs to be adjusted to accommodate different image regions, affecting image quality and visibility.
Innovation Solution
A processor and control method for an imaging apparatus that records images from different regions of a light-receiving area, performs image shake correction by moving the imaging element or lens, and adjusts the movable range and image processing parameters to improve image quality and visibility, especially in crop recording mode by setting a larger movable range and enhancing edge part image processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the movable range of the imaging element or lens is increased to improve image shake correction performance, then image stabilization capability is improved, but the device complexity and control difficulty increase
Solution Approach 1:
The patent implements dynamic adjustment of the movable range based on the imaging mode. In crop recording mode, the movable range is set to a first (larger) range, while in normal recording mode, it is set to a second (smaller) range. This dynamic adaptation allows the system to optimize shake correction performance for each mode without requiring the system to constantly manage the maximum possible range, thereby reducing unnecessary control complexity while maintaining reliability.
2Manufacturing precision
If the movable range is adjusted between different recording modes, then image quality and visibility are improved, but the ease of operation and mode switching complexity increase
Solution Approach 1:
The system automatically determines the appropriate movable range based on the currently active imaging mode (crop recording mode or normal recording mode) without requiring manual user intervention. The processor automatically switches between the first movable range and second movable range according to the mode, making the operation transparent to the user and maintaining ease of use while ensuring optimal image quality for each mode.
3Reliability
If the movable range is set larger for crop recording mode, then image shake correction performance is improved, but the energy consumption and driving load increase
Solution Approach 1:
The patent changes the operational parameters (movable range) according to the imaging mode requirements. In crop recording mode, where higher shake correction performance is needed due to the cropped field of view, the system sets the movable range to the first (larger) range. In normal recording mode, it reduces the movable range to the second (smaller) range, thereby reducing energy consumption and driving load when maximum correction performance is not required.
