Image Transmission Device for Arbitrary Region Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies are limited in transferring data from images in regions with arbitrary shapes, as they primarily support rectangular regions, making it difficult to efficiently transmit data from non-rectangular areas.
Innovation Solution
A transmission device and method that sets and transmits region information for each row of an image, allowing data to be transmitted in regions with arbitrary shapes by including information such as the position, identification, and size of the region within the region information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If rectangular region cutting technology is used, then data transfer efficiency is improved for rectangular regions, but the ability to transfer data from arbitrary shaped regions deteriorates
Solution Approach 1:
The patent segments an arbitrary shaped region into multiple rectangular sub-regions (first region and second region). Each rectangular sub-region can be independently processed and transmitted using existing rectangular region cutting technology, while collectively they represent the arbitrary shaped region of interest.
Solution Approach 2:
The patent embeds multiple rectangular regions within an arbitrary shaped region. The arbitrary shaped region acts as a container that holds several rectangular sub-regions, allowing the system to leverage rectangular region processing capabilities while achieving arbitrary shape support.
2Reliability
If the entire image is transferred, then complete image data is transmitted, but data transfer time increases and power consumption increases
Solution Approach 1:
The patent extracts only the necessary region of interest from the entire image for transmission. By identifying and extracting specific rectangular sub-regions that constitute the arbitrary shaped ROI, the system transmits only essential data, reducing transfer time and power consumption while maintaining data completeness for the intended purpose.
Solution Approach 2:
Instead of transferring the entire image (excessive action), the patent transfers only the partial regions that constitute the arbitrary shaped ROI. This partial action approach reduces data volume and transfer time while providing sufficient data for the application's needs.
3Ease of manufacture
If rectangular region cutting is used, then implementation is simple, but flexibility in selecting arbitrary shaped regions deteriorates
Solution Approach 1:
The patent segments complex arbitrary shaped region selection into simpler rectangular sub-region selections. Each rectangular sub-region can be defined using simple coordinate parameters, maintaining implementation simplicity while achieving arbitrary shape flexibility through the combination of multiple segments.

AI summary
There is provided a transmission device including: an image processing unit that sets region information corresponding to a region set in an image for each of rows in the image and causes the set region information and region data corresponding to the region to be transmitted for each row. The region information includes information indicating a position of the row and information indicating a position of a column of the region included in the row.
