PTZ Camera Display Processing for Capture Direction Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In monitoring camera systems with PTZ capabilities, it is difficult for operators to determine the image capture conditions and tour status of cameras solely by viewing the displayed images, as the captured image does not provide clear information about the image capture position or camera direction changes.
Innovation Solution
A display processing apparatus and method that receives images from cameras capable of changing their capture direction, displaying the image in one region and indicating the capture range in another, along with obtaining data for image capture orders to provide visual representations of the camera's capabilities and changes in capture direction, allowing for clearer understanding of the image capture status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only the captured image is displayed on the display apparatus, then the display is simple and clear, but the operator cannot determine the image capture conditions or camera tour status
Solution Approach 1:
The patent adds a second display region that provides contextual information about capture conditions and camera status, transforming the display from a single-dimension image presentation to a multi-dimension information presentation. This resolves the contradiction by adding information without fundamentally complicating the display structure.
Solution Approach 2:
The patent creates a visual representation (second region) that copies and represents the camera's capture range and position information. This graphical copy provides the missing contextual information without requiring additional physical cameras or sensors.
2Ease of operation
If the display shows only the captured image, then the interface is simple, but the operator cannot understand the camera's current direction or tour progress
Solution Approach 1:
The patent divides the display into two distinct regions with different functions: the first region shows the captured image while the second region shows the capture range indication. This local differentiation allows each region to specialize in presenting specific types of information, improving overall monitoring understanding without overwhelming the interface.
Solution Approach 2:
The display information is segmented into two separate regions: captured image display and capture range indication. This segmentation allows operators to quickly scan and understand both the actual capture content and the camera's operational context without information overload.
3Productivity
If the system displays captured images during preset tour, then the image changes automatically, but the operator cannot track the camera tour status
Solution Approach 1:
The second display region provides continuous feedback about the camera's current capture range and position during automated preset tours. This visual feedback loop allows operators to track tour progress and understand which preset position the camera is currently at, resolving the information loss during automated operation.

AI summary
A display processing apparatus for displaying, on a display unit, an image captured by an image capture apparatus capable of changing an image capture direction performs first display processing in which an image captured by the image capture apparatus is displayed in a first region of the display unit while the image capture direction is changed, and performs second display processing in which, in a second region indicating a range in which the image capture apparatus can perform image capture by changing the image capture direction, display according to the image capture direction in which the received image was captured is performed.
