Camera Preview Angle Control Under High-Magnification Shake Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices struggle to change the angle of view while maintaining shake correction in high magnification environments, often mistaking intentional user movements for unwanted shaking.
Innovation Solution
An electronic device with a processor that enables angle of view adjustment through user inputs, distinguishing between intentional movements and shaking, and maintains shake correction by activating a zoom lock function to fix the angle of view during high magnification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If shake correction is applied in high magnification environment, then preview image stability is improved, but angle of view change capability deteriorates
Solution Approach 1:
The system dynamically switches between two operational modes: shake correction mode and angle of view change mode. The processor detects user input patterns and transitions the camera system from applying shake correction (for stable preview) to allowing angle of view changes (for compositional adjustment), and vice versa. This dynamic mode switching resolves the contradiction by making the system adaptable to different user needs at different times.
Solution Approach 2:
The system changes the parameter of shake correction application based on detected user intent. When intentional movement is detected, the processor modifies the shake correction parameters to allow angle of view changes while maintaining stabilization for unintentional shake. This parameter adjustment enables the system to provide both stability and angle of view change capability under different conditions.
2Stability of the object's composition
If shake correction is continuously applied, then preview image stability is improved, but user intent recognition accuracy deteriorates
Solution Approach 1:
The shake correction function is segmented into two distinct operational phases: unintentional shake correction and intentional movement accommodation. The processor divides the continuous shake correction application into discrete segments based on user input detection, applying stabilization only when unintentional shake is detected and allowing movement when intentional angle of view change is detected. This segmentation improves intent recognition accuracy by clearly distinguishing between different types of camera movement.
Solution Approach 2:
The system implements feedback mechanisms where the processor continuously monitors camera movement patterns and user inputs, then adjusts shake correction application accordingly. When user input indicating intentional movement is detected, the system provides feedback by modifying shake correction behavior, which improves the accuracy of user intent recognition by creating a responsive loop between detection and action.

AI summary
An electronic device example embodiment may include: a camera; a display; and at least one processor electrically connected to the camera and the display. The at least one processor may drive the camera so as to obtain an image, display, on the display, a first preview image for at least a partial area of the image on the basis of a magnification set to a magnification greater than or equal to a reference magnification, activate an angle-of-view fixing function for fixing the angle of view of the camera to a first angle of view corresponding to the first preview image, obtain a user input for changing from the first angle of view to a second angle of view while the angle-of-view fixing function is activated, and in response to obtaining the user input, display, on the display, a second preview image corresponding to the second angle of view in the image.
