Camera Information Handover for Pre-Entry Image Preparation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems struggle to effectively prepare for an object entering their field of view, leading to inefficiencies in video encoding and image processing.
Innovation Solution
A method and system that triggers a camera to generate intra frames, adjust image processing parameters, and adjust exposure time before an object enters its field of view, based on information from another device indicating the object's location and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the camera waits until the object appears in the field of view to start processing, then the response time is delayed, but the processing can be performed after the object is detected
Solution Approach 1:
The camera system performs preliminary actions by generating intra frames and adjusting image processing parameters before the object actually appears in the field of view. The system uses information from a first device to predict object arrival and proactively prepares the camera in advance, thereby reducing response time while maintaining detection reliability through predictive positioning.
2Manufacturing precision
If the camera generates intra frames continuously, then the image quality is maintained, but the encoding bit load increases
Solution Approach 1:
The camera generates intra frames in advance before the object appears, rather than continuously. This preliminary generation of intra frames ensures high image quality is ready when needed, while the bit load is distributed over multiple frames rather than concentrated, effectively managing the encoding resource consumption.
Solution Approach 2:
The camera divides the image field into multiple subareas and applies different encoding strategies to different segments. By segmenting the field of view and applying intra encoding only to relevant subareas where objects are predicted to appear, the system maintains image quality in critical regions while reducing overall bit load.
3Measurement precision
If the camera adjusts exposure time to capture moving objects, then the motion is captured accurately, but the risk of motion blur increases
Solution Approach 1:
The camera adjusts exposure time in advance based on predicted object movement. By proactively extending the exposure time before the object appears and then adjusting it dynamically when the object is detected, the system captures motion accurately while minimizing motion blur through timely parameter adjustment.

AI summary
A system and method trigger a second camera in a camera system to perform an action prior to an object appearing in the field of view of the second camera. The camera system includes the second camera for which a location and a field of view is known, and at least a first device for which a location is known. The method comprises receiving, in the second camera, information indicating that the object is approaching the field of view of the second camera. The received information indicates a location and a direction of movement of the object, and, in response to the received information, triggers the second camera to action prior to the object appearing in the field of view of the second camera by: generating an intra frame or initiating an intra refresh procedure, adjusting one or more image processing parameters, or adjusting an exposure time.
