Imaging Apparatus Head Posture Detection Clipping Region Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging technologies face challenges in accurately clipping the region viewed by the user from omnidirectional images due to deviations in calibration settings caused by changes in the positional relationship between the line-of-sight detection apparatus and the photographer.
Innovation Solution
An imaging apparatus that includes a detection unit for detecting the posture of a user's head region, a decision unit for determining a recording region to be clipped based on the detected posture, and a notification unit for encouraging adjustments to the recording region when displacement is detected, thereby reducing deviation in calibration settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic line-of-sight detection is used to determine clipping region, then imaging operation becomes easier, but measurement precision deteriorates due to detection errors
Solution Approach 1:
The system displays the detected line-of-sight position on a screen and receives user feedback to correct positional deviations. The correction information is stored and used to adjust the clipping region, creating a feedback loop that improves measurement precision while maintaining ease of operation.
Solution Approach 2:
A display screen serves as an intermediary between the line-of-sight detection apparatus and the final clipping region determination. It allows users to visually verify and correct detection results, bridging the gap between automatic detection and accurate region specification.
2Measurement precision
If calibration processing is performed before imaging, then measurement precision improves, but deviation occurs during imaging due to positional relationship changes
Solution Approach 1:
The system dynamically adjusts the clipping region during imaging based on real-time detection of head posture changes. Instead of relying on static calibration settings, the system continuously adapts to positional relationship changes between the detection apparatus and the user's head.
Solution Approach 2:
The system performs preliminary calibration to establish baseline parameters, then uses these as reference points for subsequent real-time adjustments. The correction information stored from calibration serves as a foundation for dynamic adjustments during imaging.
3Measurement precision
If manual clipping specification is used, then measurement precision improves, but device complexity increases due to multiple processing tasks
Solution Approach 1:
The system automatically determines the clipping region based on detected head posture and stored correction information, eliminating the need for users to manually perform image conversion and clipped region specification. The system serves itself by using detection data to automatically set accurate clipping regions.

AI summary
An imaging apparatus includes an imaging unit; a detection unit configured to detect a posture of a head region of a user with respect to the imaging apparatus; a decision unit configured to decide, on the basis of the posture of the head region detected by the detection unit, a recording region to be clipped from a range of imaging by the imaging unit; a determination unit configured to determine whether or not a displacement of the recording region in the imaging range is to be adjusted; and a notification unit configured to transmit, in a case where it is determined by the determination unit that the displacement of the recording region is to be adjusted, a notification that encourages the adjustment of the displacement of the recording region to a display device that displays information related to the displacement of the recording region.
