Self-Timer Imaging Apparatus with Subject Detection and Zoom Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cameras with self-timers are not user-friendly for setting viewing angles, especially when the camera is not on a tripod, leading to difficulties in capturing intended images as the photographer's position changes during self-timer imaging, resulting in subjects being outside the set viewing angle or unnecessarily widened angles.
Innovation Solution
An imaging apparatus with an imaging section, an imaging area setting section, and an imaging control section that recognizes and adjusts the viewing angle to include intended subjects within the imaging area, allowing for easy capture of intended images during self-timer operations by temporarily imaging and adjusting the zoom to ensure all subjects are centered.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera is placed on a surface without a tripod during self-timer imaging, then the operation becomes more convenient, but the viewing angle cannot be properly set and subjects may fall outside the imaging area
Solution Approach 1:
The system performs preliminary imaging before the actual self-timer capture to detect the positions of photographic subjects. Based on this preliminary detection, the imaging area is determined and the zoom lens is adjusted to ensure all subjects are properly framed in the final image, eliminating the need for precise manual viewing angle setting.
Solution Approach 2:
The system uses preliminary imaging results as feedback to automatically adjust the imaging parameters. The detection results from preliminary imaging are used to determine the appropriate imaging area and zoom level, creating a closed-loop control system that adapts to the actual scene composition.
2Adaptability or versatility
If the viewing angle is automatically widened by zooming to include all photographic subjects, then subjects are unfailingly included in the imaging field, but the intended viewing angle is lost and subjects appear off-center
Solution Approach 1:
The system dynamically adjusts the zoom lens based on the detected positions of photographic subjects in the preliminary imaging. The imaging area is determined by the actual subject positions, and the zoom is adjusted accordingly to include all subjects while maintaining the intended viewing angle, rather than using a fixed wide-angle approach.
3Ease of operation
If the camera direction is shifted during self-timer imaging, then the photographer can enter the imaging field more easily, but the set viewing angle shifts from the center and subjects are shown on one side
Solution Approach 1:
The system performs preliminary imaging to detect subject positions before the photographer enters the frame. The imaging area is determined based on these preliminary results, and the zoom is adjusted accordingly. This preliminary action ensures that even if the camera direction shifts, the final image will be properly centered on the subjects.

AI summary
A digital camera captures at least photographic subjects intended to be positioned on left and right ends of a group photograph (temporary imaging), and prompts a user to designate the photographic subjects (may move) intended to be positioned on the left and right ends. Next, the digital camera, which has been placed on a suitable surface (such as on a desk), moves the optical zoom further to the wide-angle side than during the temporary imaging, and performs actual imaging when the self-timer reaches time up. Then, the digital camera identifies the photographic subjects designated by the temporary imaging within the actually captured image, and after determining the left, right, upper, and lower ends of a clipping area such that the identified photographic subjects are included, clips an image of the determined clipping area as a final image.
