Abstract:
An object of the invention is to provide an imaging system and an imaging control method that remove user discomfort in the display of an image associated with the adjustment of the direction of an optical axis of a pan tilt camera and improve visibility. The above-mentioned object is achieved by an imaging system including a camera that captures an image of an object to acquire object image data, pan/tilt means for rotating the camera in a pan direction and a tilt direction perpendicular to the pan direction, input means for enabling a user to desiplate a designation point at an arbitrary position of a display screen, designated position acquisition means for acquiring positional information of the designation point, pan/tilt control means for linearly moving an optical axis of the camera from a current position to a position of a designated object corresponding to the designation point to linearly move the designated object from the current position of the display screen to a center of the display screen, and image processing means for rotating the object image data displayed on the display screen on the optical axis of the camera and aligning a vertical direction after the movement of the optical axis with a vertical direction before the movement of the optical axis.

Claim (Index 5):
The imaging system according to  claim 1 , further comprising:\n means for acquiring a first pan-direction rotation angle and a first tilt-direction rotation angle of the camera at a current position with respect to an initial position and calculating a first pan/tilt rotation matrix from an initial-position unit normal vector of an imaging surface at the initial position; means for calculating a current-position unit normal vector of the imaging surface in a case in which the initial-position unit normal vector is rotated by the first pan/tilt rotation matrix; means for calculating a second pan/tilt rotation matrix from the current-position unit normal vector for the designation point; means for calculating a movement destination target vector in a case in which the current-position unit normal vector is rotated by the second pan/tilt rotation matrix; means for calculating a second pan-direction rotation angle and a second tilt-direction rotation angle from the initial-position unit normal vector, using the movement destination target vector; means for calculating a movement-destination pan-direction rotation angle from a difference between the second pan-direction rotation angle and the first pan-direction rotation angle; and means for calculating a movement-destination tilt-direction rotation angle from a difference between the second tilt-direction rotation angle and the first tilt-direction rotation angle, wherein the pan/tilt control means controls the pan/tilt means on the basis of the movement-destination pan-direction rotation angle and the movement-destination tilt-direction rotation angle.
