Display Control Apparatus Synchronizing Multi-Screen Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-screen display systems require complex configurations and controls due to the need for separate display control command transmission, time synchronization, and offset time generation apparatuses, making it difficult to synchronize display image timings across multiple display apparatuses.
Innovation Solution
A display control apparatus connected to a first display apparatus and a cooperation apparatus, which includes a display image generation unit, output units, and an output timing control unit that adjusts the timing of the first display image based on the synthesized image delay time to synchronize the output of images across multiple display apparatuses, allowing for a simple configuration and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate display control command transmission apparatus, time synchronization server apparatus, and offset time generation apparatus are used, then display timing synchronization can be achieved, but the configuration and control become complex
Solution Approach 1:
The patent combines multiple separate apparatuses (display control command transmission apparatus, time synchronization server apparatus, and offset time generation apparatus) into a single display control terminal. This integration maintains the timing synchronization functionality while reducing system complexity and the number of required components.
Solution Approach 2:
The display control terminal is designed to perform multiple functions simultaneously: it acts as a display control command transmission apparatus, a time synchronization server apparatus, and an offset time generation apparatus. This multi-functionality eliminates the need for separate dedicated apparatuses for each function.
2Reliability
If multiple separate apparatuses are used for display control, then timing synchronization can be maintained, but the control process becomes complex
Solution Approach 1:
By merging the control functions of multiple apparatuses into a single display control terminal, the patent simplifies the control process. The integrated terminal handles command transmission, time synchronization, and offset generation in a unified manner, making the system easier to operate and manage.
3Ease of operation
If a simple configuration is used, then the system is easier to operate, but it becomes difficult to synchronize display image timings across multiple display apparatuses
Solution Approach 1:
The display control terminal is designed with multi-functionality, integrating timing synchronization capabilities directly into the control terminal. This allows the system to maintain reliable timing synchronization while using a simpler configuration without requiring separate dedicated synchronization apparatuses.

AI summary
A display image generation unit generates a first display image to be output to a display apparatus and a second display image to be output to a slave display control terminal. A first output unit outputs the first display image to the display apparatus. A second output unit outputs the second display image to the slave display control terminal. A frame progress computation unit controls a timing of the output of the first display image by the first output unit based on a synthesized image delay time being a delay time from the output of the second display image to the slave display control terminal by the second output unit to output of a synthesized image from the slave display control terminal to the display apparatus, the synthesized image being obtained by synthesizing a third display image with the second display image in the slave display control terminal.
