Camera device with rotary base

摘要

A camera device with a rotary base has an automatic panning function of imaging a predetermined zone while reciprocating in a preset panning direction. The camera device includes: an imaging unit configured to image a subject and output a video signal; a rotary base configured to cause the imaging unit to rotate in a panning direction and a tilting direction; a motion and face detecting unit configured to detect the motion or face of the subject based on the video signal output from the imaging unit; and a tilt control instruction creating unit configured to create a tilt control instruction based on the detection result from the motion and face detecting unit and give the tilt control instruction to the rotary base to cause the imaging unit to rotate in the tilting direction.

1. A camera device with a rotary base having an automatic panning function of performing an imaging operation in a predetermined panning direction at a first panning speed, said camera device comprising:
an imager configured to image a subject and output a video signal; a rotary base configured to cause the imager to rotate in a panning direction and in a tilting direction; a motion and face detector configured to detect motion or a face of the subject within the image based on the video signal output from the imager; a tilt control instruction creator configured to create a tilt control instruction and to transmit the tilt control instruction to the rotary base to cause the imager to rotate in the tilting direction; and a pan control instruction creator configured to create a pan control instruction and to transmit the pan control instruction to the rotary base to control a speed at which the imager rotates in the panning direction, wherein, when the motion or face is not detected by the motion and face detector the imager is caused to rotate in the predetermined panning direction at the first panning speed; and when the motion or face is detected by the motion and face detector, the imager is caused to rotate in the predetermined panning direction at a second panning speed lower than the first panning speed until the motion or face is no longer detected by the motion and face detector, and wherein the predetermined panning direction is independent of a direction of movement of the motion or face of the subject within the image.
