Display Control Device Priority-Based Time Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In digital signage systems, when the number of images to be displayed increases, the display time of each image is shortened, reducing visibility, as existing systems do not effectively manage display priority, leading to uniform reduction in display time for all images.
Innovation Solution
A display control device with an acquisition unit, storage unit, and display control unit that acquires images, stores them, and controls their display time based on priority, ensuring images with high priority are displayed for a longer time, while reducing the display time of lower-priority images to maintain overall visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of registered images is increased, then the quantity of information to be displayed is improved, but the display time of each image is shortened reducing visibility
Solution Approach 1:
The patent applies local quality by assigning different display times to different images based on their individual priorities. High-priority images are allocated longer display times while low-priority images receive shorter display times, rather than applying a uniform display time to all images. This resolves the contradiction by allowing the system to maintain both a large number of registered images and adequate visibility for important images simultaneously.
Solution Approach 2:
The patent changes the parameter of display time dynamically based on the priority level of each image. By introducing priority as a variable parameter, the system can adjust display times flexibly - increasing display time for high-priority images and decreasing it for low-priority images - thus maintaining overall system capacity while ensuring visibility of critical information.
2Productivity
If the display time of each image is shortened to accommodate more images, then the productivity of information delivery is improved, but the visibility and reliability of individual images deteriorates
Solution Approach 1:
The patent ensures reliability by applying local quality differentiation - high-priority images receive sufficient display time to maintain visibility and reliability, while low-priority images are allocated minimal display time. This selective approach maintains the reliability of important information delivery while maximizing overall productivity through efficient use of display time resources.
3Ease of operation
If uniform display time is allocated to all images, then the ease of operation is improved, but the adaptability to different image priorities deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-assigning priority levels to images before display. This allows the system to automatically adjust display times based on predetermined priorities without requiring complex real-time decisions, thus maintaining ease of operation while achieving high adaptability to different image priorities.

AI summary
A display control device includes an acquisition unit that acquires an image, a storage unit that stores plural images acquired by the acquisition unit, and a display control unit that controls each image stored in the storage unit to be displayed sequentially on a display device during a fixed time, and performs control of changing a time for which each of an acquired new image and the plural images stored in the storage unit is displayed on the display device according to a display priority of each image in a case where the acquisition unit acquires the image.
