Camera Zoom Lens Position Retention for Seamless Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In digital cameras, when switching from still image capturing to moving image capturing or vice versa, the field angle and framing often change, leading to deviations in the recorded image, causing user discomfort due to inconsistent framing between the two modes.
Innovation Solution
The method involves retaining field angle information during mode switching and using it to return the field angle to its original state when switching back to the moving image capturing mode, ensuring consistent framing by storing and retrieving zoom position information and other parameters as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If still image capturing is performed during moving image capturing, then the ability to capture both still and moving images is improved, but the field angle and framing of the moving image change causing deviation and user discomfort
Solution Approach 1:
The patent applies preliminary action by storing the field angle information before switching to still image capturing mode. This allows the system to remember the original framing state and restore it after the still image capture sequence, preventing framing deviation without requiring complex real-time adjustments during mode switching.
2Adaptability or versatility
If field angle and framing are changed during still image capture, then the camera can adapt to different capturing needs, but the recorded moving image shows deviation from the original framing
Solution Approach 1:
The patent applies parameter changes by managing the field angle parameter through storage and restoration. The system changes the field angle parameter when needed for still image capture, then restores it to the original value before resuming moving image capture, thus maintaining framing accuracy while allowing necessary adjustments during operation.
3Adaptability or versatility
If the camera switches between still image and moving image capturing modes, then the functionality is enhanced, but the field angle and framing become inconsistent between modes
Solution Approach 1:
The patent applies preliminary action by capturing and storing field angle information before mode switching occurs. This stored information serves as a reference to restore the original framing state after switching back to moving image mode, ensuring framing stability is maintained despite the mode transition.
Solution Approach 2:
The patent applies feedback by using the stored field angle information as a reference to verify and restore the correct framing state after mode switching. This feedback mechanism ensures that the framing returns to the expected state, maintaining consistency between different capturing modes.

AI summary
According to an electronic camera capable of capturing a still image during capturing of a moving image, by storing the zoom lens position information at that time when capturing of the moving image is temporarily stopped for capturing of the still image and using the field angle information or the like recorded after capturing of the still image is terminated, the zoom lens can be automatically returned to the original zoom position so as to prevent the generation of an uncomfortable feeling between the moving image before capturing of the still image and the moving image of which capturing is restarted just after termination of the still image capturing.
