Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems with multiple circuits face challenges in reducing processing load and accelerating image data processing due to the need for high-speed input of large amounts of data, leading to increased costs and insufficient load reduction.
Innovation Solution
The system divides image data between two image processing circuits, where one circuit processes a portion of the effective region using vertical light-shielded region data and transmits unprocessed data to the second circuit for further processing, allowing for concurrent data transmission and reduced processing load.

Engineering Contradiction Analysis
1Productivity
If all image data is input into multiple image processing circuits simultaneously, then processing load is distributed, but data transmission speed requirements increase and cost increases
Solution Approach 1:
The effective region of the image data is divided into multiple regions (first region, second region, third region) that are processed by different image processing circuits. The first image processing circuit processes the first region, while the second image processing circuit processes the second and third regions. This segmentation allows each circuit to handle a portion of the data, reducing the transmission burden while maintaining parallel processing capability.
Solution Approach 2:
The first image processing circuit performs correction processing on the first region using the optical black region data before transmitting the processed results to the second image processing circuit. This preliminary processing reduces the amount of raw data that needs to be transmitted and processed by subsequent circuits, thereby reducing transmission speed requirements.
2Productivity
If each image processing circuit processes the entire image, then processing is simplified, but processing load on each circuit increases and acceleration is insufficient
Solution Approach 1:
The image processing task is segmented across multiple circuits with the first image processing circuit handling correction processing on the first region and the second image processing circuit handling the second and third regions. This division of labor reduces the processing load on each individual circuit while achieving parallel processing acceleration.
Solution Approach 2:
The first image processing circuit acts as an intermediary that performs preliminary correction processing on the first region using optical black region data before passing the processed data to the second image processing circuit. This intermediary processing step reduces the overall processing burden on the second circuit.
3Measurement precision
If correction processing is performed on all regions, then image quality improves, but processing time increases
Solution Approach 1:
Correction processing is segmented to be performed only on the first region by the first image processing circuit, while the second and third regions are processed by the second image processing circuit. This segmentation allows correction processing to be distributed across multiple circuits simultaneously, improving image quality without significantly increasing total processing time.
Solution Approach 2:
The first image processing circuit performs correction processing on the first region using optical black region data as a preliminary step before the second image processing circuit processes the remaining regions. This preliminary correction reduces noise in the processed region, improving overall image quality while maintaining efficient processing throughput.
