Abstract:
1. A camera platform system that includes a camera that outputs a photographed image, a lens, and a camera platform that operates at least one function selected from zoom/focus/tilt/pan/iris of the camera or lens in response to an operation instruction output from an operation device, the camera platform system comprising: a drive control unit configured to convert the operation instruction output from the operation device into a drive control signal corresponding to any one of driven objects of the zoom/focus/tilt/pan/iris; a motion prediction position calculation unit configured to calculate a motion prediction position of any one of the driven objects of the zoom/focus/tilt/pan/iris based on the drive control signal converted by the drive control unit; a motion prediction position output unit configured to output the motion prediction position, which has been calculated by the motion prediction position calculation unit, as motion prediction position information; and a storage unit configured to store a delay time correction value for correcting a delay time from the conversion of the drive control signal to the calculation of the motion prediction position, and a backlash correction value for correcting backlash when any one of the driven objects is operated, wherein the motion prediction position calculating unit calculates a motion prediction position based on the drive control signal before a predetermined time as the delay time correction value and the drive control signal before driving for a predetermined drive amount as the backlash correction value.
