Photographing Apparatus Swing Orbit Angle Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing photographing technologies face challenges in capturing high-speed swing movements, such as golf and baseball swings, due to insufficient memory capacity and delayed shutter response, making it difficult to accurately photograph specific moments like the impact moment.
Innovation Solution
A photographing apparatus and method that allow for input of a region of interest in a swing movement, determining the rotational angle of the swing object, and automatically photographing at the optimal time based on this angle, while correcting for distortions caused by angles between the reference plane and the swing object, and between the apparatus and the subject.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high speed and high resolution photographing is performed, then the quality of capturing swing movements is improved, but the memory capacity becomes insufficient
Solution Approach 1:
The patent applies local quality by photographing only the region of interest (ROI) rather than the entire scene. The processor identifies and captures only the specific area containing the swing movement at high resolution, while other areas are photographed at lower resolution or not at all, thereby reducing overall memory consumption while maintaining high photographing quality for the critical region
Solution Approach 2:
The patent segments the photographing process into multiple frames captured at different time points during the swing movement. By dividing the continuous swing motion into discrete sequential frames and storing them separately, the system optimizes memory usage by only retaining essential high-resolution data for each segment rather than continuously storing all intermediate states
2Ease of operation
If manual shutter pressing is used, then the operation is simple, but the timing accuracy for capturing critical moments is insufficient
Solution Approach 1:
The patent applies preliminary action by pre-setting the region of interest and photographing parameters before the swing movement occurs. The processor is configured to automatically recognize the swing movement pattern and trigger photographing at the optimal moment without requiring manual intervention, thereby eliminating shutter response delay while keeping the operation simple
Solution Approach 2:
The patent implements feedback by continuously monitoring the swing movement through the display screen and using the detected swing orbit and rotational angle to automatically determine the precise photographing timing. The system provides visual feedback of the swing progression and automatically triggers the shutter at the critical moment, combining ease of operation with high timing accuracy
3Device complexity
If photographing is performed without correction, then the process is straightforward, but distortion in the swing orbit occurs
Solution Approach 1:
The patent introduces an intermediary correction process that acts as a mediator between the raw photographing data and the final swing orbit analysis. The processor applies mathematical corrections to account for the angle between the reference plane and swing object, and the angle between the photographing apparatus and subject, thereby eliminating distortion while adding only moderate processing complexity
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting the photographing parameters based on the detected swing orbit characteristics. The processor modifies the photographing timing and angle parameters in real-time to compensate for distortion, ensuring accurate swing orbit capture while maintaining manageable device complexity through automated parameter optimization

AI summary
A photographing apparatus for photographing a scene happening in a very short moment, such as an impact moment, in a high speed movement, such as a golf swing movement, a baseball swing movement, etc., and a method of controlling the photographing apparatus are provided. The method of controlling the photographing apparatus includes: receiving an input with respect to a region of interest during the swing movement; receiving a portion of the swing movement, which is input on an area of a screen, in a state in which a live view image is displayed on the screen; determining a rotational angle of a swing object based on the received portion of the swing movement; and determining a point in time of photographing with respect to the region of interest, based on the determined rotational angle, and photographing a subject at the determined point in time of photographing.
