Image Display Device Prioritizing Frame Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display devices face challenges in managing the processing load and prioritizing image display when receiving frame images from multiple sources, often resulting in reduced information transmission and potential frame deletion due to excessive data loads.
Innovation Solution
An image display device with a communication unit, display unit, storage unit, acquisition unit, determination unit, and control unit that receives frame images, stores priority information, and adjusts data transmission based on processible information, status information, and priority settings to optimize data amount and reduce processing load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the amount of information of transmitted videos is reduced based on display area resolution, then the processing load of the reception side is reduced, but the information amount required by the user is lost
Solution Approach 1:
The patent changes the parameter basis from display area resolution to photographing status information (such as focus state, zoom state, pan/tilt state) to determine video data amount. This allows the system to maintain high information quality for important images while reducing data for less critical ones, resolving the contradiction between processing load and information preservation.
Solution Approach 2:
The patent implements a feedback mechanism where the image display device transmits control information (photographing status, priority levels) back to the image pickup devices. These devices use the feedback to dynamically adjust their transmission data amounts, enabling adaptive control that balances processing load with information quality based on real-time photographing conditions.
2Quantity of substance
If multiple frame images are received from multiple image pickup devices, then the display content is enriched, but the processing load exceeds the processible information capacity
Solution Approach 1:
The patent applies local quality by assigning different data amount requirements to different image pickup devices based on their specific photographing status and priority levels. Instead of uniform data reduction, each device's transmission quality is locally optimized according to its contribution to the overall display content, allowing rich multi-device display within processing capacity.
Solution Approach 2:
The system dynamically changes the data amount parameter for each image pickup device based on photographing status information. Devices capturing critical moments or important subjects transmit higher data amounts, while others transmit reduced data, enabling the system to handle multiple simultaneous streams without exceeding processing capacity.
3Quantity of substance
If the data amount of transmitted videos is reduced, then the network information amount is reduced, but the video quality deteriorates
Solution Approach 1:
The patent changes the basis for data amount determination from static display resolution to dynamic photographing status information. This allows the system to maintain high video quality for images captured under important conditions (focus, zoom, pan/tilt operations) while reducing data for routine captures, thus preserving quality where it matters most while reducing overall network information volume.

AI summary
An image display device may include a communication unit that receives frame images sequentially transmitted from image pickup devices, a display unit that displays the frame images, a storage unit that stores processible information on an amount of the frame images and priority information indicating priorities of the frame images, an acquisition unit that acquires status information, a determination unit that determines a data amount of the frame images transmitted by each of the image pickup devices within a predetermined period of time based on the processible information and the priority information stored in the storage unit and the status information acquired by the acquisition unit, and a control unit that performs control that causes information corresponding to the data amount determined by the determination unit to be transmitted from the communication unit to each of the plurality of image pickup devices.
