Cloud Image Layer Extraction for Mobile Editing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices lack the storage capacity and processing power to handle large image data files like Adobe Photoshop documents, making it impractical to download and edit them directly on these devices due to storage and bandwidth limitations.
Innovation Solution
A cloud-based image service generates image previews and layer extractions of multi-layered images, allowing mobile devices to display and edit specific layers without downloading the entire file, using an imaging application for previews and an extraction application for full-resolution layer extractions, which are composited on the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire multi-layered image file is downloaded to the mobile device, then the user can edit all layers locally, but the storage capacity and bandwidth limitations of mobile devices make this impractical
Solution Approach 1:
The patent segments the multi-layered image file into individual layer files, allowing the mobile device to download and store only the specific layers needed for editing rather than the entire composite file. This division enables efficient use of limited storage space while maintaining full editing capability for selected layers.
Solution Approach 2:
The patent extracts specific layers from the multi-layered image file and downloads only those extracted layers to the mobile device. This selective extraction approach eliminates the need to store the complete file, significantly reducing storage requirements while preserving the ability to edit the extracted layers.
2Productivity
If the entire multi-layered image file is downloaded, then all layers can be edited, but the network bandwidth consumption becomes excessive
Solution Approach 1:
By segmenting the image file into separate layers, the system enables selective downloading of only the layers required for the current editing task. This segmentation reduces network bandwidth consumption significantly compared to downloading the entire file, while maintaining full editing functionality for the selected layers.
Solution Approach 2:
The patent implements partial action by downloading only the necessary portion (specific layers) rather than the complete file. This approach achieves sufficient editing capability without the excessive bandwidth consumption associated with transferring the entire multi-layered image file.
3Quantity of substance
If layer extractions are generated and downloaded for each selected layer, then storage and bandwidth usage are minimized, but the system complexity increases
Solution Approach 1:
The patent introduces a cloud-based image service as an intermediary between the multi-layered image source and the mobile device. This intermediary handles the complex tasks of file segmentation, layer extraction, and selective delivery, thereby reducing the complexity burden on the mobile device while achieving efficient storage and bandwidth utilization.
Solution Approach 2:
Instead of transferring the entire original file, the system creates and downloads simplified copies (individual layer extractions) that contain only the necessary data for editing specific layers. This copying approach reduces storage requirements and simplifies the data structure on the mobile device.
Data Source
AI summary
In embodiments of document layer extraction for mobile devices, an image service can receive a request from a mobile device for a multi-layered image, and the image service generates a layer extraction as a full-resolution image of each of the layers of the multi-layered image. The image service can then generate a component representation of the layer extractions that correspond to selected layers of the multi-layered image, where the layer extractions are independently editable in the component representation. The image service can then communicate the component representation of the layer extractions that are independently editable and correspond to the selected layers of the multi-layered image to the mobile device for use with an image editing application on the mobile device, and the image service receives image edit changes made to one or more of the selected layers in the component representation of the multi-layered image from the mobile device.
