Solution Overview

Problem

Existing techniques for navigating digital images do not allow for the creation of specific, zoomable regions within an image, and existing image compression methods cannot limit access to certain regions, leading to inefficient data transmission and user navigation limitations.

Innovation Solution

A method and device for creating navigation regions in a digital image encoded at multiple resolution levels by selecting and modifying data packets to define accessible and inaccessible regions, using a marker and specific data segment to indicate navigation regions, and optimizing file size by removing unnecessary data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If image compression techniques are used to define regions of interest, then regions of interest can be created in the image, but access cannot be limited to certain regions

Engineering Contradiction:

Improveregion definition capabilityVSAvoidaccess control

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent segments the encoded image data into distinct packets, where each packet corresponds to a specific region of the image. By selectively including or excluding packets in the transmitted data stream, the system divides the image into accessible and inaccessible regions, enabling both region definition and access control simultaneously.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the entire image is stored at multiple resolutions, then navigation throughout the image is possible, but file size and data transmission volume increase

Engineering Contradiction:

Improvenavigation capabilityVSAvoiddata volume

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent extracts only the necessary data packets corresponding to remarkable regions from the complete multi-resolution image data. By removing unnecessary packets that represent inaccessible regions, the system reduces file size and data transmission volume while preserving navigation capability within the defined remarkable regions.

Inventive Principle:

Principle #2Taking out (Extraction)

3Loss of information

If all data packets are transmitted, then complete image data is available, but transmission time and bandwidth consumption increase

Engineering Contradiction:

Improveimage data completenessVSAvoidtransmission time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The patent transmits only the partial set of data packets necessary to reconstruct the remarkable regions, rather than transmitting the complete image data. This partial transmission approach maintains sufficient information for navigation within remarkable regions while significantly reducing transmission time and bandwidth consumption.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A method of creating a remarkable region in a digital image encoded at a plurality of resolution levels, the encoding data being organized in packets, each packet comprising a field of encoded data, the method including the steps of: selecting at least one remarkable region in at least one resolution level of the image, selecting data packets corresponding to the selected region, constructing an encoded form comprising the selected packets and modified packets, the modified packets corresponding respectively to the packets not selected and comprising an empty data field defining an inaccessible region.
