Abstract:
1. An automatic tracking image pickup system, comprising: an image pickup apparatus picking up an image of an object; a driving unit changing an image pickup direction of the image pickup apparatus; a recognition unit recognizing an object to be tracked in a pickup image obtained by the image pickup apparatus; and a controller controlling a speed of the driving unit based on a difference between a position of the object to be tracked in the pickup image and a target position in the pickup image, wherein: the controller controls the speed of the driving unit in an initial mode until the object to be tracked reaches a predetermined position in the pickup image after the recognition unit recognizes the object to be tracked for first time, and in a normal mode after the object to be tracked reaches the predetermined position; and the controller controls the speed of the driving unit so that a gain for obtaining the speed of the driving unit based on the difference in the normal mode becomes larger than a gain used in the initial mode.
