Solid Imaging Apparatus Overlapping Shutter and Detection Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing imaging apparatus requires a significant time for detection processing, leading to a delay between object detection and completion of imaging processing, which can result in the object not being captured in the final image, especially when the object moves during this time.
Innovation Solution
A solid imaging apparatus with a control unit that initiates the shutter operation for at least one row of pixels during detection processing at a first reading speed and subsequently switches to a second reading speed, allowing for simultaneous or early initiation of high-resolution reading, thereby reducing the overall processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If detection processing is completed before starting shutter operation, then detection accuracy is improved, but imaging processing time increases and object may not be captured
Solution Approach 1:
The patent applies preliminary action by starting the shutter operation for at least one row of pixels during the detection processing period. This allows the imaging process to begin before detection is fully complete, overlapping the two operations in time. The control unit initiates the shutter operation at a timing that occurs during detection processing, thereby reducing the total time from detection start to imaging completion while still maintaining detection accuracy through the use of data read at a first reading speed for detection purposes.
2Productivity
If reading operation is performed at high speed, then imaging processing time is reduced, but detection processing may be compromised
Solution Approach 1:
The patent applies segmentation by dividing the pixel area into different reading speed zones or phases. Data is read from the pixel area at a first reading speed for detection processing, and then at a second reading speed for imaging processing. This segmentation allows the system to optimize for detection accuracy during the detection phase and for imaging speed during the imaging phase, without compromising either function.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting the reading speed parameter based on the processing stage. The control unit changes the reading speed from a first reading speed during detection processing to a second reading speed during imaging processing. This parameter adjustment allows the system to adapt to different operational requirements at different times, maintaining both detection accuracy and imaging efficiency.

AI summary
[Problem] To provide a solid imaging apparatus that is able to shorten the time from the detection of an object to the completion of imaging processing.[Solution] A solid imaging apparatus includes a control unit that controls a shutter operation for a pixel area having a plurality of pixels arranged in matrix, and a reading operation from the pixel area at a first reading speed and a second reading speed. The control unit starts the shutter operation for at least one row of the pixel area after the reading operation at the first reading speed is completed, and during execution of detection processing of an object read from the pixel area.
