Imaging Apparatus Angle of View Control for Broadcast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In video production and distribution, especially in settings like television broadcasting, obtaining an image with an appropriate angle of view using a small number of imaging apparatuses is challenging due to the need for multiple cameras and complex camera control, which increases costs and complicates operations.
Innovation Solution
An information processing apparatus and method that sets candidates for angles of view based on the captured image range and adjusts the imaging angle of view using a combination of wide-angle and PTZ cameras, allowing for efficient selection and control of camera angles to achieve desired views with improved image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple imaging apparatuses are used to capture images with various angles of view, then the quality and variety of captured images are improved, but the device complexity and operational complexity increase
Solution Approach 1:
The imaging apparatus is designed to perform multiple functions: capturing wide-angle images, capturing narrow-angle images, and providing image data for angle-of-view calculation. This multi-functionality allows a single apparatus to replace what would traditionally require multiple specialized cameras, thereby reducing device complexity while maintaining the ability to provide various angles of view
Solution Approach 2:
The system changes the parameter of angle of view dynamically by calculating the appropriate angle based on subject position and imaging conditions. Instead of using multiple fixed-angle cameras, a single camera adjusts its effective angle of view through computational processing, allowing the system to adapt to different imaging scenarios without adding physical devices
2Adaptability or versatility
If multiple imaging apparatuses are used to capture images with various angles of view, then the quality and variety of captured images are improved, but the operational complexity increases
Solution Approach 1:
The imaging apparatus automatically calculates the appropriate angle of view based on captured image data and imaging conditions, without requiring manual intervention. The system self-adjusts by computing the angle of view from the subject's position and imaging parameters, eliminating the need for operators to manually configure multiple cameras or calculate angles, thereby significantly reducing operational complexity
3Device complexity
If a small number of imaging apparatuses are used, then device complexity and costs are reduced, but the ability to capture images with appropriate angles of view deteriorates
Solution Approach 1:
The system introduces an intermediary computational process that calculates the angle of view from captured image data. This intermediary calculation layer allows a single imaging apparatus to effectively provide multiple angle-of-view options by processing the captured images computationally, thereby compensating for the reduction in physical devices and maintaining adaptability
Solution Approach 2:
The system transitions from a physical dimension solution (multiple cameras at different positions/angles) to a computational dimension solution (calculating angle of view from image data). By moving the angle-of-view functionality from physical hardware to computational processing, the system maintains versatility while using fewer imaging apparatuses
4Adaptability or versatility
If the imaging angle of view is adjusted frequently to track fast-moving subjects, then the ability to capture appropriate views is improved, but motion blur increases
Solution Approach 1:
The system performs preliminary calculation of the angle of view based on predicted subject position and imaging conditions before capturing the final image. By pre-calculating the appropriate angle rather than adjusting during exposure, the system avoids mid-shutter adjustments that would cause motion blur, thereby maintaining both tracking capability and image quality
