Digital Camera Auto-Stop Recording via Object Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital photographing apparatuses with moving image recording functions face challenges in storage capacity and reproduction time due to large file sizes, as they record unnecessary information, and users struggle to manage recording status, especially in mobile devices with limited storage and unclear display interfaces.
Innovation Solution
A digital photographing apparatus that automatically stops and resumes moving image recording based on the presence of a target subject in the photographing domain, using object detection algorithms to determine the subject and control recording, thereby reducing unnecessary data capture and improving user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous moving image recording is performed, then complete recording of all frames is achieved, but storage capacity consumption increases and reproduction time increases
Solution Approach 1:
The system performs preliminary action by detecting the target subject before recording starts and continuously monitoring during recording. When the target subject is detected to be absent, the system proactively stops recording in advance, preventing unnecessary frames from being captured and stored, thus reducing storage capacity consumption while maintaining recording reliability for relevant content.
Solution Approach 2:
The system extracts and separates the essential recording function from continuous operation. By using object detection to identify when the target subject is present or absent, the system extracts only the necessary recording portions and stops recording when the subject is not detected, thereby reducing the quantity of stored data while preserving the essential recording content.
2Ease of operation
If manual control of recording stop is provided, then user convenience is improved, but operation complexity increases and user burden increases
Solution Approach 1:
The system implements self-service by automatically detecting the target subject and controlling the recording stop/resume function without requiring manual user intervention. The object detection algorithm autonomously determines when to stop or resume recording based on subject presence, eliminating the need for complex control interfaces and reducing user burden while maintaining ease of operation.
Solution Approach 2:
The system uses feedback from object detection results to automatically control recording operations. The detection information about target subject presence is fed back to the recording control mechanism, which automatically adjusts recording status accordingly, thereby simplifying the control interface and reducing operational complexity while maintaining user convenience.
3Extent of automation
If object detection function is added, then automatic recording control is achieved, but device complexity increases
Solution Approach 1:
The system applies multi-functionality by integrating the object detection function with the existing recording control mechanism. The same processing unit that handles recording control also performs object detection and automatic stop/resume decisions, allowing one system to serve multiple functions (recording control + object detection + automation) without proportionally increasing device complexity.
Solution Approach 2:
The system merges the object detection function with the recording control function into a unified processing mechanism. By combining these functions, the system achieves automatic recording control through object detection while minimizing the increase in device complexity, as the detection and control processes share resources and processing units.

AI summary
Provided is a method of controlling a digital photographing apparatus. The method includes: determining a target subject; determining whether the target subject exists in a moving image photographing domain; determining whether a condition of temporarily stopping recording of a moving image based on whether the target subject exists is satisfied; and temporarily stopping the recording of a moving image when the condition is satisfied.
