Transmission Device Partial Image Region Packet Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transmission systems face challenges in efficiently managing large-capacity data transmission, often leading to system overload and potential data transmission failures, particularly when transmitting entire images, which can be mitigated by transmitting only partial regions of images instead.
Innovation Solution
A communication system that includes a transmission device and a reception device, where the transmission device processes and transmits packets containing region information and partial image data, with headers including identification information, error correction codes, and an extension region to indicate the presence of region data, allowing the reception device to restore partial images efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If entire image data is transmitted, then complete image information is provided, but transmission load increases and system overload occurs
Solution Approach 1:
The image data is divided into multiple packets, with each packet containing a specific region of the image. The transmission device transmits only the necessary partial regions (regions of interest) rather than the entire image, segmenting the data transmission into manageable chunks that reduce overall transmission load while maintaining essential information delivery
Solution Approach 2:
The patent extracts and transmits only the relevant partial regions of the image that contain important information, rather than transmitting the complete image data. This extraction principle allows the system to focus on transmitting only the necessary data portions, reducing transmission load while preserving critical image information
2Quantity of substance
If partial region data is transmitted, then transmission load is reduced, but data structure complexity increases
Solution Approach 1:
Each packet is segmented into distinct fields including header information, payload containing region data, and extension regions. This structured segmentation provides clear organization that manages complexity through standardized formats, making it easier to process and transmit partial image regions efficiently
Solution Approach 2:
The patent introduces intermediary elements such as extension regions and specific header fields that act as mediators between the partial region data and the complete image reconstruction process. These intermediaries facilitate the transmission of region information without requiring complex custom protocols, managing structural complexity through standardized intermediary components
3Measurement precision
If region information is transmitted for each line, then precise region restoration is enabled, but transmission overhead increases
Solution Approach 1:
The image is processed and transmitted line by line, with each line containing region information for precise restoration. This line-level segmentation enables the reception device to accurately reconstruct the partial image region by processing each line sequentially, maintaining high restoration precision while managing transmission overhead through incremental data delivery

AI summary
A transmission device includes an image processing unit that controls transmission of a first packet including region information regarding a region detected from an image and controls transmission of a second packet for each of lines in which at least the region has been detected in the image. The second packet comprises a header including information regarding the line, and a payload including region data concerning a partial region corresponding to the line, out of the region, in which the header includes: identification information of the data included in the payload; an error correction code of the information included in the header; and an extension region provided so as to be interposed between the identification information and the error correction code, and information indicating whether or not the region data is included in the payload corresponding to the header is set in at least a part of the extension region.
