Autofocus Parallelism in Electronic Image Capture Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image capture devices require significant time for processing and necessitate user intervention to designate subjects for focus and capture, making the process inconvenient.
Innovation Solution
An electronic device with an image capture device and control device that autonomously detects objects, determines subjects for focus and capture timing without user input, and commences autofocus processing before image capture operation determination is complete, allowing for parallel execution of autofocus and image capture processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If autofocus processing is performed after subject determination, then focusing accuracy is improved, but image capture time increases
Solution Approach 1:
The system performs preliminary autofocus processing on detected objects before final subject determination is complete. The control device starts autofocus on preliminary determined subjects, and if a different subject is determined later, the autofocus target is switched. This preliminary action reduces overall capture time while maintaining focus accuracy through potential target switching.
Solution Approach 2:
The autofocus target is made dynamic rather than static. The system initially focuses on preliminary determined subjects, but maintains the capability to switch focus targets if a different subject is determined during ongoing processing. This dynamic approach allows the system to adapt to changing determination results while reducing waiting time.
2Measurement precision
If user designates subjects for focus and capture, then subject selection accuracy is improved, but user effort and operation complexity increase
Solution Approach 1:
The control device performs automatic subject determination and autofocus target selection without requiring user input. The system detects objects in the image, determines subjects based on detection results, and automatically sets autofocus targets. This self-service approach eliminates user effort while maintaining accurate subject selection through algorithmic determination.
Solution Approach 2:
The manual user selection process is replaced with automated object detection and subject determination algorithms. The control device uses image processing and analysis to automatically identify and select subjects, substituting the mechanical interaction of user designation with an automated computational system.
3Stability of the object's composition
If subject determination is performed before autofocus, then processing sequence logic is improved, but overall processing time increases
Solution Approach 1:
The control device performs preliminary subject determination based on initial object detection, then immediately starts autofocus processing on these preliminary subjects. This preliminary action allows processing to begin before final subject determination is complete, reducing overall time while maintaining logical sequence through potential target switching if subjects are re-determined.

AI summary
An electronic device (1) includes a control device (10) configured to carry out: image capture operation determination processing in which a first subject is determined without a user operation and image capture timing is determined; and autofocus processing in which a second subject is determined without a user operation and an image capture device is controlled to focus on the second subject, the autofocus processing being commenced before the image capture operation determination processing finishes.
