Auto Pre-Capture Control for Dynamic Subject Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic apparatuses with imaging functions, there is a time lag between issuing a shooting instruction and the actual capture, leading to missed shots, especially in capturing rapid movements, and the pre-capture function increases power consumption, requiring manual operation to toggle it on and off.
Innovation Solution
An electronic apparatus with an operation unit for preparing and recording shots, an identification unit for subject recognition, and a control unit that automatically enables the pre-capture function based on subject identification, allowing for automatic preparation and recording without photographer intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pre-capture function is enabled to capture rapid movements, then the reliability of capturing desired images is improved, but the power consumption increases
Solution Approach 1:
The system performs preliminary shooting actions before the actual shooting instruction is given. When the release button is pressed to the first stage, the camera automatically captures and stores images in the buffer memory in advance, so that when the second stage is pressed, the desired image is already available for recording, eliminating the need for continuous pre-capture and reducing power consumption.
Solution Approach 2:
The system dynamically changes the shooting parameters based on the detected subject type. When a moving subject is detected, the pre-capture function is activated with appropriate settings; when a stationary subject is detected, the function is deactivated. This parameter change optimizes the balance between capture reliability and power consumption based on actual shooting conditions.
2Reliability
If the pre-capture function is automatically enabled to prevent missed shots, then the reliability of capturing desired images is improved, but the device complexity increases
Solution Approach 1:
The camera system performs self-service by automatically detecting the subject type (moving or stationary) and autonomously deciding whether to activate the pre-capture function. The subject identification unit and control unit work together to make this decision without requiring the photographer to manually configure settings, thereby improving reliability while avoiding the complexity of manual operation interfaces.
3Use of energy by moving object
If the photographer manually switches the pre-capture function to reduce power consumption, then the power consumption is reduced, but the ease of operation deteriorates
Solution Approach 1:
The system eliminates the need for manual switching by implementing self-service functionality. The subject identification unit automatically detects whether the subject is moving or stationary, and the control unit automatically adjusts the pre-capture function settings accordingly, freeing the photographer from manual operations while optimizing power consumption based on actual shooting conditions.
Solution Approach 2:
The system uses feedback from the subject identification unit to automatically adjust the pre-capture function. The detection results about subject movement are fed back to the control unit, which then automatically enables or disables the pre-capture function, creating a closed-loop system that optimizes power consumption without requiring manual intervention.

AI summary
An electronic apparatus includes an operation unit configured to output a first operation instruction instructing preparation for shooting, and a second operation instruction instructing recording of a captured image; an identification unit configured to identify a subject; a control unit configured to, while the first operation instruction is being output, execute control to capture the image data by the imaging unit and retain the image data in a storage unit based on identification information of the identification unit; and a recording unit configured to, when the second operation instruction is output, record, onto a recording medium, image data of an image captured by the imaging unit in response to the second operation instruction, and image data retained in the storage unit at a timing closest to when the second operation instruction is output.
