Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capturing systems struggle to effectively track multiple targets within the angle of view while maintaining their size within a predetermined range, leading to potential loss of tracking due to targets becoming too small.
Innovation Solution
An information processing device and method that includes a controller and image capturing device, which detect and track multiple targets, controlling zooming to ensure all targets remain within the view and within a predetermined size range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the image capturing unit zooms in to capture a single tracking target, then the size of the tracking target in the image increases, but multiple tracking targets cannot be included within the angle of view
Solution Approach 1:
The patent applies dynamics by making the zooming control adaptive and flexible. The controller dynamically adjusts the zooming level based on the detected positions and sizes of multiple tracking targets, changing the angle of view in real-time to accommodate all targets within the predetermined size range, rather than using a fixed zoom level
Solution Approach 2:
The patent changes the parameter of angle of view by controlling the zooming level. The controller calculates the appropriate angle of view based on the spatial relationships between multiple tracking targets and adjusts the zooming accordingly, allowing the image capturing unit to capture all targets while maintaining their sizes within the predetermined range
2Adaptability or versatility
If the image capturing unit zooms out to include multiple tracking targets within the angle of view, then all tracking targets can be captured, but the size of each tracking target becomes too small for effective tracking
Solution Approach 1:
The system dynamically adjusts the angle of view based on the detected positions and sizes of tracking targets. By continuously monitoring the image and calculating the required zoom level, the controller maintains optimal viewing conditions for all targets, preventing them from becoming too small while ensuring they remain within the angle of view
Solution Approach 2:
The patent implements feedback control where the controller continuously monitors the sizes of tracking targets in the captured image and adjusts the zooming level accordingly. This feedback mechanism ensures that all tracking targets maintain appropriate sizes for effective tracking while remaining within the field of view
3Device complexity
If the image capturing unit maintains a fixed angle of view, then the structure is simple, but tracking targets may move out of the angle of view during tracking
Solution Approach 1:
The system transitions from a fixed angle of view to a dynamic, adjustable angle of view. The controller continuously monitors the positions of tracking targets and adjusts the zooming level in real-time, ensuring that all targets remain within the angle of view throughout the tracking process, thereby improving reliability without excessive complexity

AI summary
An information processing device includes an image capturing device and a controller. The controller includes a first memory storing first instructions, and a first processor executing the stored first instructions causing the controller to set a plurality of tracking targets to be tracked during image capturing by the image capturing device. The image capturing device includes a second memory storing second instructions, and a second processor executing the stored second instructions causing the image capturing device to detect sizes of the tracking targets in an image captured by the image capturing device, and control zooming of the image capturing device such that the plurality of tracking targets are included within an angle of view of the image capturing device. The zooming is controlled such that the size of each tracking target among at least some of the plurality of tracking targets falls within a predetermined range.
