Image Transmitting Apparatus Region-Based Resolution Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-resolution image transmission and storage require significant bandwidth and storage capacity, as existing methods either degrade image quality by increasing compression ratios or fail to effectively reduce data volume by differentiating between regions of interest and non-interest.
Innovation Solution
An image transmitting apparatus detects regions of interest and applies different low-pass filters to reduce resolution only in non-interest areas, while maintaining high resolution in interest areas, allowing for efficient transmission and storage by reducing data volume without degrading image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-resolution image capturing is performed to monitor a wide area in detail, then image quality and monitoring coverage are improved, but transmission capacity and storage capacity requirements increase significantly
Solution Approach 1:
The patent applies different quality levels to different regions of the image. Regions of interest (detected by intelligence processing such as moving object detection) are maintained at high resolution, while other regions are reduced in resolution. This allows the system to monitor a wide area in detail where needed while reducing overall data volume for transmission and storage.
2Quantity of substance
If compression ratio is increased to reduce data amount, then transmission and storage capacities are reduced, but image quality is degraded
Solution Approach 1:
Different compression ratios are applied to different regions of the image based on their importance. Regions of interest undergo lower compression to maintain quality, while non-critical regions undergo higher compression to reduce data volume. This selective compression approach resolves the contradiction between reducing data amount and maintaining image quality.
3Manufacturing precision
If entire image is transmitted at high resolution, then monitoring detail is improved, but transmission load and storage requirements increase
Solution Approach 1:
The system transmits high-resolution image data only for detected regions of interest while transmitting reduced-resolution data for the remainder of the image. This selective transmission approach maintains monitoring detail where it is most needed while significantly improving transmission efficiency and reducing storage requirements.
Solution Approach 2:
The image is segmented into regions of interest and non-interest areas based on intelligence processing results. This segmentation allows the system to apply different transmission strategies to different portions of the image, optimizing both monitoring detail and transmission efficiency by sending full-resolution data only where necessary.

AI summary
An image transmitting apparatus includes a region detecting unit detecting, in an image, a region of interest matching a predetermined condition; a resolution converting unit selecting, for reducing resolution of the image, an image passed through a low-pass filter as an image outside the detected region of interest and an image not passed through the low-pass filter as an image inside the region of interest; and a transmitting unit transmitting the image with reduced resolution and positional information of the region of interest. An image receiving apparatus includes a resolution restoring unit performing image quality improvement processing on the region of interest obtained from the positional information and included in the image transmitted from the image transmitting apparatus so as to increase resolution in the region of interest; and a combining unit combining the image inside the processed region of interest with the image outside the region of interest.
