Handheld Visual Data Capture with On-Device Logo Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld digital devices struggle to efficiently display visually encoded data alongside associated graphical representations, such as brand logos, due to limited memory and the need for network downloads, which slows user experience and incurs additional costs, while also making it difficult to locate stored data.
Innovation Solution
A method and system that captures and decodes visually encoded data, including visual elements, to display them in a composite view on handheld devices, transforming the visual elements to fit the display area and establishing a one-to-one relationship between encoded data and visual elements, allowing for unique and efficient presentation without relying on network downloads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If graphics are preloaded in device memory, then display speed is improved, but device memory requirements increase and new companies cannot be supported
Solution Approach 1:
The system performs preliminary actions by capturing the visual element (logo/image) and associated data together in a single image capture operation. The visual element is extracted and stored locally in device memory at the time of barcode scanning, eliminating the need for separate network downloads later. This preliminary capture and extraction action resolves the contradiction by preparing all necessary display assets beforehand without requiring pre-loaded graphic libraries for all possible companies.
Solution Approach 2:
The system creates a local copy of the visual element (logo or image) directly in device memory when the barcode is scanned. Instead of relying on network downloads or pre-loaded graphics, the visual element is copied from the captured image along with its associated data. This copying mechanism enables fast local display while supporting any company, as the graphic is captured and stored on-demand rather than requiring extensive pre-loaded memory.
2Adaptability or versatility
If graphics are downloaded during decoding, then adaptability to new companies is improved, but user experience speed deteriorates and network charges are incurred
Solution Approach 1:
The system performs the graphic capture and extraction action preliminarily during the initial image capture phase, rather than waiting for network download during decoding. By extracting the visual element directly from the captured image at the time of scanning, the system eliminates the time-consuming network download step while maintaining adaptability to support any company's branding.
Solution Approach 2:
The system makes the visual element and data self-sufficient by capturing them together in a single image. The visual element contains all necessary identification information, allowing the system to extract and store it locally without requiring network connectivity or external downloads. This self-service approach eliminates network dependency and download delays while maintaining full adaptability.
3Loss of information
If voluminous decoded data is stored, then data availability is improved, but data location difficulty increases
Solution Approach 1:
The system merges the visual element (logo/image) and the decoded data into a single unified storage unit or record. When data is stored, it is associated with its corresponding visual element, creating a combined entry that can be easily located and retrieved together. This merging eliminates the problem of locating scattered data by allowing users to find everything through a single visual identifier.
Solution Approach 2:
The system creates a visual copy or thumbnail of the visual element that serves as an index or marker for the associated decoded data. This visual copy is stored with the data record, enabling quick visual identification and location of stored information. Users can browse stored data by viewing these visual copies rather than searching through text, dramatically improving data location ease.
Data Source
AI summary
Visually encoded data is captured along with one or more visual elements, the encoded data is decoded and one composite view is displayed that incorporates information related to the decoding data, such as a decode confirmation or decoded data, and the visual elements. The recognition and decoding process may additionally provide for transforming the captured visual elements to accommodate the allocated display area of small sized display, such as the display associated with a handheld image capturing device. The invention is thus suited for capturing encoded data and branding elements, such as company or product logos, and displaying the branding elements in unison with data related to the decoded information.
