20080246847 | IMAGING APPARATUS AND PAN/TILT HEAD CONTROL METHOD - 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. | 10-09-2008 |
20090009655 | IMAGING APPARATUS AND IMAGING METHOD - 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 recognized. 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 intensity is low. When an image is to be recorded, this apparatus records a color image by enabling the infrared reduction filter. | 01-08-2009 |
20100271510 | FOCUS CONTROL APPARATUS AND OPTICAL APPARATUS - A focus control apparatus includes a signal generator for generating a first signal in accordance with a predetermined frequency component of an image signal obtained by photoelectrically converting an image of a subject formed by an image-taking optical system, a detector for detecting a second signal different from the first signal, and a controller for detecting a movement of the subject based on the second signal and for switching driving of the image-taking optical system based on the detection, wherein the controller controls driving of the image-taking optical system based on the first signal. | 10-28-2010 |
