ROI Image Defect Correction via Embedded Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not have a correcting process for defective images in a region of interest (ROI) that is a partial region segmented from a captured image during data transmission.
Innovation Solution
A transmitting apparatus and a receiving apparatus are designed to include a controlling section for holding defect correcting information and a transmitting section that sends image data of an ROI as payload data and ROI information as embedded data. The receiving apparatus processes the correction of defects in the image data based on the extracted defect correcting information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If only a partial image (ROI) is transmitted instead of the entire captured image, then the data transmission load is reduced and system shutdowns are avoided, but the defective pixels in the transmitted ROI cannot be corrected using existing defect correcting information
Solution Approach 1:
The patent segments the captured image into a region of interest (ROI) for transmission while maintaining the ability to correct defects. The defect correcting information is divided into two parts: (1) defect correcting information corresponding to the ROI, and (2) defect correcting information corresponding to non-ROI areas. This segmentation allows the system to transmit only the necessary ROI data while preserving the ability to correct defects through the combined use of both defect correcting information parts.
Solution Approach 2:
The patent embeds defect correcting information for the ROI within the transmission signal structure. The controlling section holds both ROI-related defect correcting information and non-ROI defect correcting information, and the transmitting section transmits this information as part of the signal. This nesting approach allows the defective pixel correction capability to be contained within the transmitted signal without increasing the overall data transmission burden.
2Reliability
If defect correcting information for the entire captured image is transmitted, then defective pixels can be corrected, but the transmission load increases and may cause system shutdowns
Solution Approach 1:
The patent divides the defect correcting information into two distinct segments: (1) defect correcting information corresponding to the ROI, and (2) defect correcting information corresponding to non-ROI areas. The transmitting section transmits both segments as part of the signal, allowing the receiving apparatus to correct defects in the transmitted ROI using the appropriate defect correcting information without requiring transmission of the entire image's defect correcting data.
Solution Approach 2:
The patent applies local quality by providing defect correcting information specifically tailored to the ROI area that is transmitted. The controlling section manages defect correcting information locally for the ROI and separately for non-ROI areas, allowing the system to correct defects in the transmitted portion without unnecessarily transmitting correction data for the entire captured image.
3Reliability
If the transmitting apparatus includes a controlling section that holds defect correcting information, then the receiving apparatus can correct defects in the transmitted ROI, but the device complexity increases
Solution Approach 1:
The controlling section in the transmitting apparatus performs multiple functions: it holds defect correcting information for the ROI, manages defect correcting information for non-ROI areas, and controls the transmission of this information. This multi-functionality approach consolidates what would otherwise be separate components into a single controlling section, reducing overall system complexity while maintaining the ability to correct defects in transmitted images.

AI summary
It is an object to realize a correcting process for correcting a defective image in a region of interest (ROI) that is a partial region segmented from a captured image. A transmitting apparatus includes a controlling section that controls the holding of defect correcting information for use in correcting a defect in an image included in a ROI and a transmitting section that sends out image data of the image included in the ROI as payload data and sends out ROI information as embedded data.
