Solution Overview
Problem
Conventional image capturing techniques struggle to easily capture multiple images of a moving object in a composition desired by the user, as they often require manual adjustment and lack adaptive frame rate control based on the object's speed and position.
Innovation Solution
An image capturing apparatus and method that includes a detection unit for tracking the moving object's position and speed, a setting unit for adjusting the image capturing area, and a control unit that dynamically adjusts the frame rate based on the object's position and speed, ensuring optimal capture in the user-defined composition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the frame rate is fixed at a predetermined value, then the image capturing operation is simple, but the captured images may miss the moving object or fail to capture the desired composition
Solution Approach 1:
The patent applies dynamics by making the frame rate adjustable and adaptive rather than fixed. The control unit dynamically changes the frame rate based on the detected position and speed of the moving object, allowing the system to adapt to different capture scenarios and maintain reliable capture while remaining easy to operate through automated adjustments.
Solution Approach 2:
The patent changes the parameter of frame rate based on detected object characteristics. The control unit modifies the frame rate parameter according to the position and speed information obtained from the detection unit, enabling optimal capture settings without manual intervention and improving both ease of operation and capture reliability.
2Productivity
If the frame rate is increased to capture more images, then the quantity of captured images increases, but the imaging quality may deteriorate due to longer exposure time requirements
Solution Approach 1:
The system dynamically adjusts the frame rate based on real-time detection of object position and speed. When the object is detected moving quickly, the frame rate increases to capture more images. When movement is slow or the object is stationary, the frame rate decreases to maintain optimal imaging quality, thus balancing productivity and precision through adaptive control.
Solution Approach 2:
The control unit changes the frame rate parameter based on the detected motion characteristics of the object. By adjusting this parameter dynamically according to position and speed information, the system optimizes the balance between capturing sufficient images and maintaining high imaging quality, avoiding the trade-off between quantity and precision.
3Device complexity
If the image capturing area is fixed, then the device complexity is low, but the system cannot adapt to different moving object positions and speeds
Solution Approach 1:
The patent implements dynamics by enabling the image capturing area to change adaptively based on detected object characteristics. The control unit adjusts the capturing area according to the position and speed of the moving object, allowing the system to adapt to various scenarios without significantly increasing device complexity through automated control mechanisms.
Solution Approach 2:
The system changes the parameter of image capturing area based on detected object position and speed information. The control unit modifies this parameter dynamically to optimize capture settings for different motion scenarios, enhancing adaptability while maintaining reasonable device complexity through algorithmic control rather than hardware complexity.
