Camera Transmission Apparatus Image Rotation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users may misunderstand the camera's control response to their imaging direction movement instructions due to the camera's complex pan, tilt, and rotation mechanisms, which can lead to inappropriate control perceptions.
Innovation Solution
A transmission apparatus and method that includes a direction change mechanism, a rotation mechanism, and control units to manage the camera's movements and prevent image rotation during control, ensuring accurate user feedback and reducing misinterpretation of control actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the pan mechanism and rotation mechanism are controlled simultaneously to change imaging direction, then the imaging direction can be changed accurately according to user instruction, but the displayed image rotates causing user confusion
Solution Approach 1:
The patent separates the image display function from the imaging direction control function. While the pan and rotation mechanisms are controlled to change the imaging direction accurately, a separate display image generation unit creates an undisplayed image that compensates for the rotation. This segmentation allows the imaging direction to be controlled precisely while preventing the displayed image from rotating, thus resolving the contradiction between control accuracy and user understanding.
2Ease of operation
If the tilt mechanism is used to change imaging direction, then the imaging direction changes without rotation, but the mechanism cannot move in all directions users may instruct
Solution Approach 1:
The patent makes the imaging apparatus capable of handling multiple types of movement instructions (tilt-only directions and pan+rotation directions) through a unified control system. The control unit determines the appropriate combination of mechanisms based on the user's instruction, making the system adaptable to various movement directions while maintaining simple operation through a single interface.
3Adaptability or versatility
If multiple mechanisms (pan, tilt, rotation) are combined to achieve user-instructed imaging direction movement, then the imaging direction can be changed in any direction, but the control becomes complex and confuses users
Solution Approach 1:
The patent introduces an undisplayed image as an intermediary element between the multiple mechanisms and the user. This undisplayed image serves as a mediator that absorbs the complexity of coordinating pan, tilt, and rotation mechanisms while presenting a simple, non-rotating display to the user. The undisplayed image compensates for mechanism rotations, allowing flexible imaging direction changes without exposing users to the underlying control complexity.

AI summary
A first control unit of a transmission apparatus controls pan, tilt, and rotation mechanisms according to a movement direction indicated by a movement instruction for changing an imaging direction of an imaging unit. A second control unit of the transmission apparatus performs control so as to prevent transmission of captured image data captured during the control of the pan, tilt, and rotation mechanisms, during the control performed by the first control unit.
