Image Processing Apparatus for Motion Moment Specification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies fail to accurately specify images of critical moments in motion sequences, such as a golf swing, due to limitations in detecting precise object positions and speeds within moving images.
Innovation Solution
An image processing apparatus that acquires a sequence of images, sets specification areas on each image, and calculates pixel value changes to identify specific moments in the motion of an object, allowing for the extraction of relevant images based on these changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If Doppler sensor is used to detect ball position and calculate speed, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent replaces the Doppler sensor-based mechanical detection system with an image processing system that uses pixel value analysis. Instead of using specialized sensors to detect ball position and calculate speed, the invention uses standard imaging devices to capture images and analyzes pixel value changes in predetermined areas to determine ball position and motion state, thereby substituting a complex sensor system with a simpler image processing approach
Solution Approach 2:
The patent creates a digital representation of the ball position by analyzing pixel values in image data. Instead of directly measuring physical quantities with sensors, the system captures visual information through imaging and derives position information from the copied visual data, allowing measurement without direct physical contact or specialized sensors
2Measurement precision
If multiple specification areas are set on each image, then measurement precision is improved, but processing time increases
Solution Approach 1:
The patent divides the image into multiple predetermined specification areas to monitor different regions where the object may be located. By segmenting the image processing task into specific areas of interest rather than analyzing the entire image, the system achieves accurate position detection across the full field of view while reducing the total number of pixels that need to be processed in each frame
Solution Approach 2:
The patent processes only the pixel values within predetermined specification areas rather than analyzing every pixel in the entire image. This partial processing approach focuses computational resources on relevant regions where object presence is expected, achieving sufficient measurement precision without the excessive processing time that would result from full-image analysis

AI summary
An image capture apparatus includes an image acquisition unit 5a, an area setting unit 5b, and an image specifying unit 5c. The image acquisition unit 5a acquires a first image group including plural images, the plural images obtained by sequentially photographing motion of an object. The area setting unit 5b sets plural areas at plural positions on each of the images of the first image group acquired by the image acquisition unit 5a. The image specifying unit 5c acquires pixel values of the plural areas set on each of the images by the area setting unit, and specifies a second image group including plural images relating to prescribed moments of motion of the object from among the first image group including plural images, based on change in the acquired pixel values of the plural areas.
