Electronic Label Control Device Using Image Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electronic shelf label display control devices are prone to display errors due to operator input errors, which can lead to incorrect pricing or information display on commodities.
Innovation Solution
A display control device that uses a camera to capture images of commodities on a shelf, identifies the commodities and their positions, and generates display information including the display position and content for electronic labels, ensuring accurate and automated information display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operator input is used to control electronic shelf label display content and position, then the system is easy to operate, but display errors may occur due to input errors
Solution Approach 1:
The system enables automatic identification of commodities and determination of display positions through image capture and processing, eliminating the need for manual operator input. The electronic shelf label system self-determines which commodity information to display and where to display it based on the captured image data, thereby preventing display errors while maintaining ease of operation.
2Device complexity
If manual control is used for electronic label display content and position, then the device complexity is low, but display errors may occur
Solution Approach 1:
The patent replaces manual mechanical control operations with an automated image-based recognition system. A camera captures images of commodities on shelves, and processing circuitry automatically identifies commodities and determines display positions, substituting human operators with an automated visual recognition system that reduces display errors while adding minimal complexity.
3Reliability
If automated image-based control is implemented, then display accuracy is improved, but device complexity increases
Solution Approach 1:
The system introduces an image capture device (camera) and processing circuitry as intermediaries between the commodities on shelves and the electronic shelf labels. This intermediary layer automatically captures commodity information, identifies items, and determines display positions, thereby improving display accuracy while keeping the added complexity manageable through standardized components.

AI summary
A control device controls electronic labels in an electronic label system. The control device includes a first interface that acquires a captured image in which a commodity is included. A second interface transmits display information to an electronic label. A processor identifies, based on a captured image received via the first interface, the commodity and the position of the commodity. The processor determines a display position on an electronic label for displaying commodity information relating to the commodity based on the position of the commodity, and generates display information including the display position and a display content based on the identified commodity and the display position. The processor transmits the generated display information to the electronic label via the second interface.
