Wide-Angle Image Region Reduction for Faster Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for delivering wide-angle images, such as omnidirectional images, result in long download times due to their large data size, and initial low-resolution display can create a poor user impression as users wait for high-resolution images to load, even with progressive image transmission techniques.
Innovation Solution
An image display system that includes a region determining unit to identify less frequently viewed regions of a wide-angle image, a reduction unit to delete those regions, and a transmission unit to send a reduced image, allowing for faster delivery without compromising image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the complete wide-angle image is transmitted to reduce image quality loss, then the image quality is improved, but the download time increases
Solution Approach 1:
The wide-angle image is divided into multiple regions based on viewing frequency analysis. Only frequently viewed regions are transmitted in high resolution, while less frequently viewed regions are excluded or transmitted at lower resolution. This segmentation allows the system to prioritize transmission of important image portions, reducing overall data size and download time while maintaining perceived image quality for the most relevant areas.
Solution Approach 2:
Different regions of the wide-angle image are treated differently based on their viewing frequency. Frequently viewed regions maintain high resolution and quality, while less frequently viewed regions are reduced or removed. This local quality differentiation ensures that the transmitted image data focuses resources on the most important areas, achieving good user experience without transmitting the complete high-resolution image.
2Loss of time
If progressive images are transmitted to reduce download time, then the download time is reduced, but the initial image quality becomes low
Solution Approach 1:
The system performs preliminary analysis of viewing frequency patterns to identify which regions will be most important to the user. Based on this pre-analysis, the system prepares and transmits the frequently viewed regions in high resolution from the start, rather than beginning with a low-resolution version. This preliminary action allows the system to optimize transmission content before delivery, ensuring good initial image quality in the most relevant areas while still reducing overall download time.
3Loss of information
If the complete wide-angle image is transmitted to maintain data completeness, then the information completeness is improved, but the data size increases
Solution Approach 1:
The system extracts and identifies the frequently viewed regions from the complete wide-angle image based on viewing frequency analysis. Only these extracted regions are transmitted in high resolution, while the less frequently viewed regions are excluded or significantly reduced. This extraction approach maintains the essential information that users are most likely to need while dramatically reducing the overall data size of the transmitted image.

AI summary
An image display system is provided that includes an information processing apparatus and a terminal apparatus that receives a wide-angle image from the information processing apparatus. The information processing apparatus includes a region determining unit that determines a region of the wide-angle image that is viewed less frequently than other regions of the wide-angle image, a reduction unit that deletes the region determined as less frequently viewed by the region determining unit from the wide-angle image to generate a reduced wide-angle image, and a first transmitting unit that transmits the reduced wide-angle image generated by the reduction unit to the terminal apparatus. The terminal apparatus includes a receiving unit that receives the reduced wide-angle image from the information processing apparatus, and an image display unit that displays the reduced wide-angle image on a display device.
