Abstract: An automatic object tracking system is configured to perform an automatic object tracking method. A horizontal coordinate axis and a vertical coordinate axis are defined in image capturing data captured by a handheld device. When a feature object is recognized, a sampling frame is set to surround the feature object, and a reference point is set within the sampling frame. A horizontal distance and a vertical distance from the reference point to a target coordinate are calculated. When the horizontal distance or the vertical distance is larger than a horizontal threshold, a turning command is issued to move the reference point towards the target coordinate horizontally or vertically by at least one horizontal unit or by at least one vertical unit. In case that plural feature objects are recognized, the handheld mobile device chooses a proper one of the plural feature objects timely to perform the panning shot.

Abstract: A method for panning shot with an image-stabilizing function is adapted for having an image capturing direction of a panning shot dock to approach an optical signal source. The method comprises: receiving an optical positioning signal from the optical signal source by using an optical-signal receiving array, generating receiving strengths separately by using a plurality of optical-signal receiving units in the optical-signal receiving array; comparing the receiving strengths, and analyzing a position of the optical signal source of the optical positioning signal relative to the optical-signal receiving array according to the receiving strengths, to generate a first turning signal; and sending the first turning signal to control the panning shot dock, to enable the image capturing direction to approach the position of the optical signal source; finally, recognizing a feature object by the handheld mobile apparatus, and taking over the control over the panning shot dock.
