Provided are an imaging device and a method for recognizing a target object, said device and method making it possible to easily capture a desired target object using a telephoto optical system and to carry out image recognition on the target object by means of a telephoto image including the target object captured by the telephoto optical system. The invention is provided with: an imaging optical system that comprises a wide-angle optical system and a telephoto optical system having a common optical axis; a directional sensor; a pan/tilt mechanism that rotates an imaging unit, which includes the imaging optical system and the directional sensor, in a horizontal direction and vertical direction; and an image acquisition unit that acquires a wide-angle image received from the directional sensor via the wide-angle optical system and a telephoto image received via the telephoto optical system. A first target object (person P) is detected from a wide-angle image W1 acquired by the image acquisition unit, the pan/tilt mechanism is controlled on the basis of information on the location of the detected first target object in the wide-angle image, image recognition is carried out on a telephoto image T2 acquired by the image acquisition unit when the first target object is located in the center of the wide-angle image, and a second target object (face F) in the first target object or in the vicinity of the first target object is recognized. |
