Solution Overview

Problem

Conventional image transmission methods transmit images at full resolution, resulting in large data amounts and low transmission efficiency.

Innovation Solution

The method involves segmenting an image into multiple regions, assigning different resolutions to these regions, and transmitting them individually, with the region containing the gaze point maintained at original resolution and other regions down-sampled to lower resolutions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If full resolution image is transmitted, then image quality is maintained, but data amount increases and transmission speed decreases

Engineering Contradiction:
Improveimage qualityVSAvoidtransmission speed
Core Design Contradiction:
Measurement precisionVSSpeed

Solution Approach 1:

The image is divided into multiple regions based on gaze information, with each region assigned different resolution levels. The region containing the gaze point is transmitted at full resolution while other regions are transmitted at lower resolutions, thereby reducing overall data amount while maintaining perceived image quality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the image are assigned different quality levels based on their importance. The gaze-point region receives high resolution for quality preservation, while non-gaze regions use lower resolution to reduce data transmission, achieving local optimization of quality versus data trade-off.

Inventive Principle:
Principle #3Local quality

2Manufacturing precision

If full resolution image is transmitted, then image detail is preserved, but transmission time increases

Engineering Contradiction:
Improveimage detailVSAvoidtransmission time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The image transmission is segmented into multiple regional images with different resolution requirements. By transmitting only the necessary high-detail regions at full resolution and other regions at lower resolution, the total transmission time is reduced while preserving critical image details in the gaze region.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of transmitting the entire image at full resolution, only the necessary portions (gaze regions) are transmitted at full resolution, while other portions use reduced resolution. This partial action approach reduces transmission time while maintaining sufficient image detail where needed.

Inventive Principle:
Principle #16Partial or excessive action

3Productivity

If image is compressed to reduce data amount, then transmission efficiency improves, but image quality deteriorates

Engineering Contradiction:
Improvetransmission efficiencyVSAvoidimage quality
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

Different compression levels are applied to different regions based on their importance. The gaze-point region maintains high quality with minimal compression, while non-gaze regions accept higher compression to reduce data amount. This local differentiation resolves the contradiction between transmission efficiency and overall image quality.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The image is segmented into gaze regions and non-gaze regions, allowing different quality settings for each segment. This segmentation enables the system to achieve good transmission efficiency through compression in non-critical regions while preserving image quality in critical gaze regions.

Inventive Principle:
Principle #1Segmentation

AI summary

Disclosed are a method and device for transmitting and displaying an image, a storage medium, and a processor. The method includes: segmenting a target image into multiple regions to obtain multiple regional images, where the multiple regions to which the regional images belong include a first region and a second region, the first region is a region on which a gaze point falls, and the second region is a region other than the first region in the target image; assigning resolutions to the respective regional images of the target image, where the respective regional images have different resolutions; and transmitting, one by one, the respective regional images have different resolutions.
