Image Pipeline Verification Using Superimposed Reference Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image information transmitted from the initial-stage image processing IC may be altered before reaching the subsequent-stage image processing IC, leading to potential erroneous recognition.
Innovation Solution
An image processing device that superimposes pattern images on unused areas of captured images, allowing for state determination through standard deviation and integrated value calculations to identify abnormalities such as image sticking, video masking, tone changes, and noise superimposition, using an initial-stage image processing unit, signal transmission circuit, image processing unit, and subsequent-stage image processing unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image information is transmitted from the initial-stage image processing IC to the subsequent-stage image processing IC, then the recognition function can be performed, but the image information may be changed during transmission causing erroneous recognition
Solution Approach 1:
The patent applies preliminary action by superimposing a reference pattern image on the captured image at the initial-stage image processing IC before transmission. This reference pattern serves as a predetermined marker that allows the subsequent-stage IC to verify whether the transmitted image information has been altered during transmission, thereby maintaining recognition accuracy despite potential transmission changes.
2Measurement precision
If a reference pattern is superimposed on the captured image, then the state of image information can be determined, but the unused area of the image is reduced
Solution Approach 1:
The patent applies local quality by placing the reference pattern image in the unused area of the captured image, specifically in regions that are not required for the main recognition function. This allows the reference pattern to be superimposed without interfering with the primary image content, thereby maintaining state determination accuracy while preserving the functional area of the image.
3Productivity
If the subsequent-stage image processing IC performs recognition processing on changed image information, then processing can continue, but erroneous recognition may occur
Solution Approach 1:
The patent applies feedback by using the reference pattern image to provide verification information to the subsequent-stage image processing IC. The reference pattern serves as a feedback mechanism that allows the system to detect whether image information has been altered during transmission, enabling the IC to continue processing while maintaining recognition accuracy through the verification provided by the reference pattern.

AI summary
An information processing device includes: an acquisition unit that acquires a captured image; a superimposition unit that generates a superimposition image in which images are superimposed on unused areas of the captured image; and a determination unit that determines a state of the captured image on the basis of characteristics of areas on which the images are superimposed in the superimposition image transmitted from the superimposition unit.
