Imaging Focus Control for Approaching Subject Video Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals capturing moving images often struggle to operate the imaging apparatus and maintain focus on the intended object during photographing, especially when they are also performing on screen.
Innovation Solution
An imaging apparatus equipped with an image sensor, memory, and processors that include a recognition unit to detect approaching or receding objects, a focus adjustment unit to adjust focus accordingly, and a generation unit to create moving images, allowing the performer to capture in-focus images without manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the performer manually operates the imaging apparatus to adjust focus, then the focus can be adjusted to the intended object, but the performer cannot simultaneously focus on the performance and operate the camera
Solution Approach 1:
The imaging apparatus automatically detects the object of interest and adjusts focus without requiring manual operation by the performer. The system serves itself by using the captured images to identify the intended subject and autonomously controlling the focus adjustment, thereby resolving the contradiction between ease of operation and focus accuracy.
Solution Approach 2:
The system continuously monitors captured images, detects the object of interest based on movement or other criteria, and uses this feedback to automatically adjust the focus. This closed-loop feedback mechanism ensures accurate focus adjustment without requiring manual intervention from the performer.
2Manufacturing precision
If the performer focuses on the intended object during photographing, then image quality improves, but the performer cannot simultaneously present the product on screen
Solution Approach 1:
The imaging apparatus autonomously identifies the intended object and adjusts focus automatically, eliminating the need for the performer to manually focus while maintaining high image quality. This self-service capability allows the performer to concentrate entirely on the performance.
Solution Approach 2:
The manual mechanical focus adjustment operation is replaced by an automated detection and control system that uses image processing and algorithms to determine the object of interest and adjust focus accordingly, substituting human operation with an automated system.
3Ease of operation
If automatic focus adjustment is implemented, then the performer can focus on performance, but the device complexity increases
Solution Approach 1:
The imaging apparatus integrates multiple functions including object detection, movement analysis, and automatic focus adjustment within a single system. The processor performs multiple tasks (capturing images, detecting objects, analyzing movement, and controlling focus) using existing hardware components, thereby minimizing additional complexity while achieving automated operation.

AI summary
An imaging apparatus includes an image sensor, a memory configured to store images, and at least one processor or circuit configured to function as the following units, a recognition unit configured to recognize a person based on images captured by the image sensor, an approach detection unit configured to detect approach of an object to the imaging apparatus, a focus adjustment unit configured to adjust a focusing state of a subject based on the images captured by the image sensor, and a generation unit configured to generate a moving image based on images captured by the image sensor and images stored in the memory, wherein, when the approach detection unit detects the approach of the object to the imaging apparatus, the focus adjustment unit changes a focus adjustment target.
