Imaging Apparatus Automatic Slow-Motion Capture via Image Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video cameras struggle to accurately capture slow-motion images of desired scenes due to reliance on control operation timing or sound triggers, which can result in missed or incomplete captures, especially in dynamic environments.
Innovation Solution
An imaging apparatus with an image recognition block that detects specific patterns in a predetermined sequence, allowing the control block to adjust the field frequency of image storage and retrieval to ensure accurate slow-motion recording of desired scenes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video taking is executed with reference to control operation timing, then the user can capture precious shooting chances, but the operation may be too fast or too slow resulting in taking a wasted part or failing to take an essential part
Solution Approach 1:
The patent replaces the mechanical/manual control operation system with an automatic image recognition system. The control block automatically determines the start and end of slow-motion recording by detecting specific image patterns (such as a ball in a specific position) through the image recognition block, eliminating the need for manual timing operations and ensuring accurate capture of essential moments without timing errors
Solution Approach 2:
The imaging apparatus performs self-service by automatically detecting the desired scene through image recognition and autonomously controlling the recording timing. The control block uses the image recognition result to automatically set the recording period, allowing the system to capture the essential part without external intervention or manual timing
2Reliability
If video taking is executed with reference to sound trigger, then the capture can be automated, but in an environment where there is a possibility of picking up many similar sounds, it may start taking with reference to a hit sound made by another player
Solution Approach 1:
The patent replaces the acoustic detection system with an optical image recognition system. Instead of detecting sound waves that can be confused with similar sounds from other players, the system uses the image recognition block to detect visual patterns (such as the position of a ball), providing reliable and unambiguous identification of the desired scene without interference from similar environmental signals
Solution Approach 2:
The patent introduces image recognition as an intermediary between the imaging result and the control decision. The image recognition block processes the imaging result to extract meaningful visual information, serving as a reliable mediator that accurately identifies the desired scene without being affected by environmental interference like similar sounds
3Productivity
If field frequency is increased for slow-motion recording, then the frame rate increases allowing slow-motion capture, but the memory storage requirement increases
Solution Approach 1:
The patent applies partial action by storing imaging results at high field frequency (240 fps) only for the specific period when slow-motion recording is needed, rather than continuously. The control block determines the exact start and end timing based on image recognition, storing data at high rate only partially during the overall operation, thus reducing total memory storage requirements while maintaining high frame rate for the critical slow-motion segment

AI summary
Application is found to, for example, a video camera with recording means united therewith. On the basis of image recognition results, in accordance with the timing of detection of images of specified pattern in specified sequence, high-speed writing of imaging results in memory is completed and the imaging results stored in the memory is saved in a recording medium.
