Innovation Solution
A photographing control device and method that includes an analysis result acquisition unit, status acquisition unit, index determination unit, evaluation value calculation unit, and image storage control unit, which assess image and object status indexes to determine the significance of captured moments and store images only when an evaluation value exceeds a predetermined threshold, ensuring timely and relevant image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If photographing and recording are performed only when face is detected, then storage capacity is saved, but images of crucial moments may be missed
Solution Approach 1:
The system changes the detection parameters from simple face detection to multi-index evaluation including face detection, motion detection, and sound level detection. This allows the system to capture images based on multiple criteria rather than a single parameter, thereby increasing the reliability of capturing crucial moments while still managing storage capacity effectively.
Solution Approach 2:
The evaluation process is segmented into multiple independent indexes (face detection index, motion detection index, sound level index) that are evaluated separately and then combined. This segmentation allows the system to flexibly determine when to capture images based on the combined evaluation results, improving the ability to capture crucial moments without unnecessarily increasing storage usage.
2Quantity of substance
If photographing is controlled only by motion state, then storage capacity is saved, but images of crucial moments may be missed
Solution Approach 1:
The system expands from single-parameter motion state control to multi-parameter evaluation including face detection, motion detection, and sound level detection. This parameter expansion enables more accurate identification of crucial moments while maintaining efficient storage utilization.
Solution Approach 2:
The photographing control system is designed to perform multiple functions: face detection, motion detection, sound level detection, and comprehensive evaluation. This multi-functionality allows the system to capture crucial moments through various detection methods rather than relying solely on motion state, thereby improving reliability while managing storage capacity.
3Reliability
If continuous photographing is performed, then crucial moments are captured, but storage capacity is consumed
Solution Approach 1:
The system automatically evaluates multiple indexes (face detection, motion detection, sound level) and makes autonomous decisions about when to capture images based on the combined evaluation results. This self-service mechanism eliminates the need for continuous photographing while ensuring crucial moments are captured, thereby conserving storage capacity effectively.
Solution Approach 2:
The system uses multi-index evaluation with threshold comparisons to determine when to capture images, changing from continuous photographing to event-driven photographing. This parameter-based control ensures storage capacity is used efficiently while maintaining high reliability in capturing crucial moments.

AI summary
A photographing control device capable of storing images to be stored at appropriate timings is provided. The analysis result acquiring unit acquires an analysis result of an image obtained by photographing an object by the photographing device. The status acquisition unit acquires a detection result obtained by detecting the status of the object by the sensor. The index determination unit determines the degree of these indexes for each of a plurality of indexes including those relating to the object based on the image analysis result and the detection result of the state of the object. The evaluation value calculation unit calculates an evaluation value for evaluating the stored value of the image using the degree of the index. When the evaluation value exceeds a predetermined threshold value, the image storage control unit 15 controls so as to store an image.
