Imaging System Region Position Adjustment for Wireless Time Lag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video camera systems experience time lag when changing the imaging direction, making it difficult to accurately image a desired subject due to delays in reflecting pan tilt operations via wireless communication paths.
Innovation Solution
A communication device and imaging system that includes a receiving unit for image data and imaging direction information, an operating unit for generating direction instructions, an image clipping unit for adjusting the image region based on the imaging direction, and a display unit for stable image display, along with a size changing unit for adjusting image size based on user input, ensuring the relative position of the clipping region remains constant with changes in the imaging direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the imaging direction is changed via wireless communication, then the video camera can image a desired subject, but a time lag occurs until the corresponding video is displayed
Solution Approach 1:
The system performs preliminary actions by predicting the user's intended imaging direction based on recent operation patterns before the actual operation is completed. This allows the clipping region to be adjusted in advance, reducing the perceived time lag when the video is displayed.
Solution Approach 2:
The system dynamically adjusts the clipping region position based on real-time imaging direction changes and predicted user intentions. Instead of static adjustment, the system continuously adapts the clipping region to maintain optimal positioning despite communication delays.
2Adaptability or versatility
If both the position of the partial region and the imaging direction are adjusted, then a desired subject can be imaged, but the system complexity increases
Solution Approach 1:
The system merges the adjustment of imaging direction and clipping region position into a unified control mechanism. By coordinating these adjustments together based on predicted user intent, the system reduces the number of independent control operations needed, thereby simplifying the overall system complexity.
Solution Approach 2:
The system implements feedback by continuously monitoring imaging direction changes and using this information to automatically adjust the clipping region position. This closed-loop control eliminates the need for complex manual coordination between multiple adjustment parameters.
3Stability of the object's composition
If the clipping region position is adjusted based on imaging direction changes, then the subject position remains stable on display, but additional processing is required
Solution Approach 1:
The clipping region position is adjusted in advance based on predicted imaging direction changes, ensuring subject position stability is maintained proactively rather than reactively. This preliminary adjustment reduces the computational burden during real-time display processing.

AI summary
A communication device includes: a receiving unit that receives image data generated by an imaging process of an imaging device facing a predetermined imaging direction and imaging direction information representing the predetermined imaging direction; an operating unit that generates direction instruction information indicating an imaging direction of the imaging device in response to an operation of the user; an image clipping unit that clips a predetermined region of the image data; a display unit that displays an image based on the image data of the predetermined region; and a region position adjusting unit that adjusts a position of the predetermined region in the image data based on the imaging direction information and the direction instruction information.
