Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera devices in manufacturing systems are large in size and have high shutter speeds, leading to increased computation loads and prolonged image processing times, which result in longer cycle times and reduced production efficiency.
Innovation Solution
A camera device with a rotary motor that rotates the imaging unit at a prescribed speed, allowing for efficient image capture and processing by ensuring the imaging unit and subject are approximately parallel, thereby reducing image distortion and processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple illumination units are equipped to capture different types of images, then image quality and information completeness are improved, but device size increases
Solution Approach 1:
The patent combines multiple illumination units (first and second illumination units with different opening sizes) into a single imaging element, allowing simultaneous capture of both mark images and work images without increasing device footprint. This merging approach resolves the contradiction by integrating multiple functions into one compact unit.
2Speed
If high shutter speed is used to capture moving works, then image capture capability is improved, but computation load increases and image processing time lengthens
Solution Approach 1:
The patent extracts and processes only the necessary information by first capturing a mark image to determine rotational position, then selectively capturing work images only at appropriate positions. This extraction approach reduces the total number of images requiring full processing, thereby reducing computation load and processing time while maintaining high shutter speed for capturing moving works.
Solution Approach 2:
The patent performs preliminary action by capturing mark images first to determine the rotational position of the imaging unit, then uses this information to guide subsequent work image capture. This preliminary determination allows the system to avoid unnecessary image processing and focuses computational resources only on relevant images, reducing overall processing time.
3Reliability
If multiple images are captured to ensure quality, then image reliability is improved, but processing time and computation load increase
Solution Approach 1:
The patent performs preliminary determination of rotational position using mark images before capturing work images. This preliminary action ensures that work images are captured only when the imaging unit is at the correct rotational position, guaranteeing image reliability while avoiding unnecessary captures that would increase processing time and reduce productivity.

AI summary
A camera device is equipped with at least one imaging unit for imaging a subject, a rotary motor for rotating the imaging unit at a prescribed rotation speed, an output unit for outputting images taken by the imaging unit, and a body which incorporates the imaging unit, the rotary motor, and the output unit. The output unit outputs at least one image, among the images, taken at an imaging position where the imaging unit and the subject are approximately parallel with each other.
