摘要： In an imaging apparatus, when a pan/tilt head is located at a predetermined position, a photographed image acquired by an imaging unit is stored as a registered image. A photographed image, which is newly acquired by the imaging unit, is compared with the registered image when the pan/tilt head is not driven from the predetermined position after the registered image is stored. The pan/tilt head is driven to an initial position if, as a result of comparison between the photographed image and the registered image, it is determined that a degree of matching between the photographed image and the registered image satisfies a predetermined condition.

摘要： An apparatus suitably detects a recording trigger even in a low-brightness or low-light-intensity environment, and acquires, from a recorded image, a high-quality image from which a person or the like can be easily recongized. When a recording trigger is to be detected, this apparatus disables an infrared reduction filter, so a recording trigger can be suitably detected even in an environment in which the brightness or light inensity is low. When an image is to be recorded, this apparatus records a color image by enabling the infrared reduction filter.
