Pan-Tilt Camera Speed Control via Tally Signal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pan-tilt camera systems lack automatic speed control adjustment based on whether the video image is being output on a program, leading to blurred images due to uncontrolled high speeds during video production.
Innovation Solution
An image capturing apparatus that determines the video image's output state and adjusts pan and tilt maximum speeds dynamically, setting speeds lower when the image is on-program and higher when not, using a control unit and reception unit to receive tally information for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the pan speed or tilt speed is increased to improve operational efficiency, then the image becomes blurred and the video image becomes unviewable
Solution Approach 1:
The patent implements dynamic speed control by automatically adjusting the maximum pan and tilt speeds based on the tally state. When the camera is on-program, the system lowers the maximum speed to prevent image blur, and when off-program, it raises the maximum speed for faster repositioning. This dynamic adjustment resolves the contradiction between operational efficiency and image clarity.
2Manufacturing precision
If manual speed adjustment is implemented to maintain image clarity, then the operator must manually change maximum speeds each time switching is performed, increasing operational complexity
Solution Approach 1:
The system uses feedback from the tally information to automatically control the maximum speeds. The control unit receives tally state information and automatically adjusts the speed parameters without requiring manual intervention. This feedback mechanism eliminates the need for operators to manually change speeds during switching, reducing operational complexity while maintaining image clarity.
3Ease of operation
If automatic speed control based on tally state is implemented, then the system complexity increases due to additional control mechanisms
Solution Approach 1:
The control unit performs multiple functions: it controls pan-tilt driving, manages speed limits, and processes tally information. By making the control unit multi-functional, the patent avoids adding separate dedicated hardware for each function, thereby minimizing the increase in device complexity while achieving automatic speed control based on tally state.

AI summary
An image capturing apparatus includes an image capturing unit configured to capture an image of an object, a driving unit configured to change an image capturing direction of the image capturing unit, a control unit configured to control the driving unit, and, a reception unit configured to receive first tally information from another apparatus, wherein the control unit is configured to control, in a case where the reception unit does not receive the first tally information, the driving unit to set a maximum speed of the driving unit at a first driving speed, and control, in a case where the reception unit receives the first tally information, the driving unit to set the maximum speed at a second driving speed lower than the first driving speed.
