Dynamic Frame Rate Adjustment for Image Capture Memory Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional high-speed camera systems face challenges in determining the optimal frame rate for capturing moving objects, leading to excessive memory usage when capturing slowly moving objects at high frame rates and obscure images when capturing rapidly moving objects at frame rates higher than necessary.
Innovation Solution
An image capturing apparatus with a storage unit for sample images and corresponding frame rates, a display unit to show these images at a predetermined frame rate, and a driving unit to adjust the frame rate based on user selection, allowing users to determine the appropriate frame rate for capturing and reproducing images of objects moving at different speeds.

Engineering Contradiction Analysis
1Speed
If the high-speed camera apparatus captures continuous images at a high frame rate, then the image capture capability for rapidly moving objects is improved, but the memory capacity becomes insufficient due to excessive image data generation
Solution Approach 1:
The patent implements dynamic frame rate adjustment based on object motion detection. The system switches between high frame rate mode (for rapidly moving objects) and low frame rate mode (for slowly moving objects), allowing the capture rate to adapt dynamically to actual scene requirements and prevent memory overflow
Solution Approach 2:
The system changes the frame rate parameter based on detected object motion characteristics. By monitoring object velocity and adjusting the capture frame rate accordingly, the system optimizes the balance between capture quality and memory usage, capturing high-speed motion when needed and reducing capture rate when motion is slow
2Speed
If the high-speed camera apparatus captures continuous images at a high frame rate, then the image capture capability is improved, but the image quality deteriorates due to motion blur
Solution Approach 1:
The system dynamically adjusts the frame rate based on actual object motion speed. When objects move slowly, the system uses lower frame rates that allow sufficient exposure time for sharp images. When objects move rapidly, the system switches to high frame rate mode to capture motion clearly, thus optimizing both image quality and motion capture accuracy
