Abstract: A remote control device 60 measures a distance to a noticed imaging target OB directly in front of the remote control device 60 by a distance measurement unit. Further, the remote control device 60 measures a movement from an initial state by a motion sensor unit and transmits imaging target position information indicative of the measured distance and movement from a communication unit to an imaging device 20. An imaging target position calculation unit provided on the imaging device 20 calculates, on the basis of the imaging target position information from the remote control device 60, a direction of the noticed imaging target OB with respect to the direction in the initial state of the imaging device 20. By generating a direction controlling signal on the basis of a calculation result of the imaging target position calculation unit and outputting the direction controlling signal to a pan head 40, the imaging direction of the imaging device 20 can be set to the direction of the noticed imaging target OB.

Abstract: A sub imaging apparatus 60 used by a user generates a sub captured image by imaging a subject OB. A main imaging apparatus 20 of which an imaging direction can be changed by a camera platform 40 is remotely controlled by the sub imaging apparatus 60 to image the subject imaged by the sub imaging apparatus 60 so as to generate a main captured image with an angle of view different from that of the sub captured image. An image combination section included in the sub imaging apparatus 60 generates a display image by combining the sub captured image generated by the sub imaging apparatus 60 with the main captured image generated by the main imaging apparatus 20. A display section included in the sub imaging apparatus 60 displays the display image generated by the image combination section. Using the sub imaging apparatus 60, the user may cause the main imaging apparatus 20 away from the sub imaging apparatus 60 to image a desired subject easily.

In a battery loading and unloading mechanism, a battery 2 is formed with projecting portions at longitudinal both ends of a back surface and along the back surface, the back surface being a surface opposite to an insertion surface of the battery, whereby even the battery formed in a flat rectangular parallelepiped and having the almost-square main surface can be prevented from being erroneously inserted into the device. The projecting portion has an inclined surface acutely inclined with respect to the back surface, and when the battery is unloaded from the device, unloading of the battery from the device is accelerated by the inclined surface undergoing contact pressure of the retaining means.
