Information Processing Apparatus for Rapid High-Resolution Tile Image Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems face delays in displaying high-resolution images when switching between regions of interest due to the need to wait for intra-frame compression to complete, especially during digital PT movement and preset tour functions, which hinders quick image display.
Innovation Solution
An information processing apparatus that communicates with a storage device to request and display high-resolution tile images pre-encoded with intra-frame and inter-frame encoding, allowing for immediate display of designated regions without waiting for intra-frame compression to finish.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If intra-frame compression is performed on video images to ensure high compression ratio, then compression efficiency is improved, but image switching speed deteriorates due to waiting time for compression completion
Solution Approach 1:
The system performs intra-frame compression in advance during the preset tour preparation phase, so that when preset positions are switched during execution, the compressed images are already ready for immediate display without waiting for compression to complete
Solution Approach 2:
The video image processing is divided into two phases: preset tour preparation phase where compression is performed, and preset tour execution phase where pre-compressed images are displayed. This segmentation allows compression and display to occur in separate time windows, eliminating the conflict between compression time and switching speed
2Ease of operation
If digital PT movement is executed frequently to enable quick position switching, then operational responsiveness is improved, but image display quality deteriorates due to insufficient time for intra-frame compression
Solution Approach 1:
The system pre-compresses images for all preset positions during the preparation phase, so that during preset tour execution, high-quality compressed images are immediately available for display without compromising image quality even during frequent position switching
3Manufacturing precision
If high-resolution tile images are transmitted to ensure image quality, then display quality is improved, but transmission time deteriorates due to large data volume
Solution Approach 1:
The video image is divided into multiple tiles, and only the specific tile corresponding to the region of interest is transmitted to the client device. This segmentation reduces the transmission data volume while maintaining high resolution for the displayed region
Solution Approach 2:
High-resolution tile images are transmitted only for the specific region of interest rather than the entire video image, optimizing transmission efficiency while maintaining display quality for the relevant area

AI summary
An information processing apparatus that communicates with a storage device that stores, at a plurality of resolutions, tile images obtained by dividing a picked-up image into a plurality of predetermined regions and to which encoding processing including intra-frame encoding and inter-frame encoding has been performed comprises: a designation unit for designating a predetermined region of the picked-up image for a preset tour in advance; a request unit for requesting the storage device to transmit the tile image including the predetermined region with higher resolution from among the plurality of resolutions; and a display control unit for cutting out the predetermined region from the tile image and cause a display unit to display the cut-out predetermined region, wherein, when the predetermined region is designated in advance, wherein, when the predetermined region is designated in advance, the request unit requests the storage device to transmit the tile image including the predetermined region.
