Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is difficult to change an angle of view in electronic devices while maintaining a stable preview screen in high magnification environments due to fixed angle of view settings.
Innovation Solution
An electronic device with a camera, display, and processor that allows users to input changes in the angle of view while correcting for shake, distinguishing between intentional and unintentional movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If shake correction is applied to provide a stable preview screen in high magnification environment, then stability of the preview image is improved, but the ability to change angle of view deteriorates
Solution Approach 1:
The system dynamically switches between two operational modes: shake correction mode (for stability) and angle of view change mode (for adaptability). The processor detects user input patterns and transitions between these modes, allowing the system to be stable when needed and adaptable when the user intends to reposition the view, thus resolving the contradiction between maintaining stability and enabling angle of view changes
2Reliability
If the angle of view is fixed at high magnification, then shake correction performance is improved, but user flexibility to adjust view deteriorates
Solution Approach 1:
The system employs dynamic mode switching based on detected user input. When the processor detects intentional user input (such as deliberate device movement or specific gestures), it transitions from shake correction mode to angle of view change mode, temporarily suspending shake correction to allow smooth view adjustment. This dynamic adaptation maintains reliable shake correction during normal operation while providing ease of operation when users need to adjust the view
3Stability of the object's composition
If shake correction is continuously applied, then image stability is maintained, but difficulty in detecting intentional movement increases
Solution Approach 1:
The system uses feedback from motion sensors and user input detection to distinguish between unintentional shake and intentional movement. The processor continuously monitors device movement patterns, sensor data, and operational context to determine whether detected motion represents user intent to change angle of view or merely shake to be corrected. This feedback mechanism allows the system to maintain image stability during normal operation while accurately detecting when intentional movement occurs
Solution Approach 2:
The shake correction function dynamically adjusts its behavior based on detected movement patterns. When the system identifies patterns consistent with intentional angle of view adjustment (such as sustained movement in a particular direction or movement exceeding certain thresholds), it temporarily modifies or suspends shake correction to allow the intended view change, thereby reducing the difficulty of detecting intentional movement while maintaining image stability during normal use

AI summary
An electronic device according to one embodiment of the present document may comprise: a camera; a display; and at least one processor electrically connected to the camera and the display. The at least one processor can 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.
