Camera platform system and imaging system

An imaging system comprising:

• a camera platform system including a camera that outputs a photographed image, a lens, and a camera platform;
• and
• an image synthesizing system that acquires motion prediction position information and a photographed image from the camera platform system, and synthesizes the photographed image with a computer graphic image using the motion prediction position information,
• wherein the camera platform system 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,
• wherein the camera platform system further comprises:
• a drive control unit configured to convert an 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 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,
• wherein the image synthesizing system calculates a delay time correction value from a time difference between the time until the motion prediction position information changes and the time until the photographed image changes;
• 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.
