Display Device Object Tracking via Coordinate Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in efficiently tracking and displaying specific objects within images, particularly in high-speed operations, which is resource-intensive and costly, especially when trying to provide features like object tracking in digital TV services.
Innovation Solution
A method and system where a first display device displays an image with a target object and communicates with a second display device to receive and transmit coordinate information of the target object from one image to another, allowing the first device to track and display the object based on the received information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a display device performs high-speed object tracking operations continuously, then tracking precision is improved, but resource consumption and cost increase
Solution Approach 1:
The patent divides the tracking system into two segments: a first display device that performs full object tracking operations, and a second display device that receives and displays the tracked object information. This segmentation allows the second device to achieve tracking functionality without performing the computationally intensive tracking operations itself, thereby reducing its resource consumption while maintaining tracking precision through the coordinated operation of both devices.
2Ease of operation
If object tracking is implemented in TV display devices, then user experience is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges the tracking functionality across two display devices, where the first device performs the complex tracking operations and the second device displays the results. This combining approach allows individual devices to have simpler architectures while the system as a whole provides advanced object tracking capabilities, thereby improving user experience without requiring each device to be overly complex.
3Measurement precision
If continuous tracking of objects in consecutive frames is performed, then tracking accuracy is improved, but processing speed requirements and resource usage increase
Solution Approach 1:
The patent extracts the computationally intensive object tracking processing from the second display device and relocates it to the first display device. The second device only needs to receive and display pre-processed tracking information, which significantly reduces its processing speed requirements while maintaining tracking accuracy through the first device's continuous analysis of consecutive frames.

AI summary
A method of operating a display device includes displaying a first image of first content, wherein the first image includes a target object, receiving information on a second coordinate of the target object included in a second image of the first content from a second display device, wherein the second image is temporally later than the first image, acquiring an image tracking the target object from the second image based on the information on the second coordinate of the target object, and displaying the acquired image.
