When a movement destination P is designated, a switching time t1 when the movement is switched from acceleration to constant-speed-movement and a switching time t2 when the movement is switched from the constant-speed-movement to deceleration are determined with respect to a designated time T0. Then, a constant-speed-movement start position A and a deceleration start position B are set. Next, the constant speed (inclination of a straight line AB) during the constant-speed-movement period is found. An operation equation of the acceleration period is determined with an exponential function so that the panhead is smoothly shifted from the acceleration to the constant-speed-movement. In like manner, an operation equation of the deceleration period is determined with an exponential function so that the panhead is smoothly shifted from the constant-speed-movement to the deceleration. <IMAGE> |
