An image signal processing DSP subjects an image captured by an imaging element having a zoom lens to image processing for identifying a tracking target. In accordance with zoom information generated by the image signal processing DSP, the main CPU controls the zoom lens and controls a turn table that moves the imaging element in panning and tilting directions in accordance with pan and tilt information, to track the tracking target. During tracking of the tracking target, a determination is made, from information about movements of the tracking target generated by the image signal processing DSP, as to whether or not the target to be tracked has intruded the inside of the area from the outside. In a case where the target has intruded the inside of a preset area from the outside, an alarm command is produced when the target continually remains in the area for; e.g., one second.

A camera device with a rotary base has an automatic panning function of imaging a predetermined zone while reciprocating in a preset panning direction. The camera device includes: an imaging unit configured to image a subject and output a video signal; a rotary base configured to cause the imaging unit to rotate in a panning direction and a tilting direction; a motion and face detecting unit configured to detect the motion or face of the subject based on the video signal output from the imaging unit; and a tilt control instruction creating unit configured to create a tilt control instruction based on the detection result from the motion and face detecting unit and give the tilt control instruction to the rotary base to cause the imaging unit to rotate in the tilting direction.

A dome-type camera includes a camera lens capable of rotating in a tilt direction, a dome cover for covering the camera lens, and an aperture control unit for controlling the amount of aperture of the camera lens. The amount of aperture is set to become smaller from an open value toward a closed value in accordance with the tilt angle of the camera lens becoming smaller from a zenith direction of the dome cover toward a horizontal direction. According to this dome-type camera, a desirable low tilt angle image with a reduced blur may be obtained even with a megapixel dome camera.

Dome-type camera and aperture control method

A camera device () includes an imaging unit () which outputs a long exposure signal and a short exposure signal in one field period. A face detection unit () detects a face area from an image captured by the imaging unit (). The weighting processing unit () applies a weighting process to luminance data of the long exposure signal in the detected face area using a weighting constant for reducing the luminance level of the long exposure signal. If the luminance level of the weighting-processed long exposure signal rises to a predetermined saturation level or higher, an exposure control unit () performs exposure control using the long exposure signal and the short exposure signal. This can suppress occurrence of a noise due to a short exposure signal (flickering) in the face area, thereby improving visibility in the face area.

An object of the present invention is to provide an electronic device capable of receiving payment of a charge required for a charging process even though a secondary battery of the electronic device ran into an overdischarge state and also extricating itself from the overdischarge state, and a charger used for the same. A charger () executes a power transmission before it conducts a proximity noncontact communication with an electronic device (), continues this power transmission until a preliminary charging stop notification signal is sent from the electronic device (), and conducts the proximity noncontact communication regarding to a billing process with the electronic device () when the preliminary charging stop notification signal is sent. After the communication regarding to the billing process is ended, the charger () gives a charge of electricity to the electronic device () again. The electronic device () charges a secondary battery () by using the power transmission, then executes the charging up to a level at which the proximity noncontact communication regarding to the billing process can be conducted, then conducts the proximity noncontact communication regarding to the billing process with the charger (), and then restarts the power transmission from the charger () to execute the charging until the secondary battery () is fully charged. In this manner, the noncontact charging and the proximity noncontact communication are executed between the electronic device () and the charger () in a time-division system.

A camera device () includes: an imaging unit () having a complementary color filter; a color temperature estimating unit () that estimates a color temperature on the basis of a video signal obtained from the imaging unit (); a color parameter calculating unit () that calculates a color parameter value corresponding to the estimated color temperature; and a color calibrating unit () that performs color calibration using the calculated color parameter value.

This allows performing color calibration with high color reproducibility using suitable color parameter values according to a change in an illumination condition as well as allows substantially reducing an amount of data required to determine the suitable color parameter values.

There is provided an imaging apparatus which can prevent a privacy zone from being shifted from a mask when a magnification converting lens is switched. The imaging unit () has an extender () which is a magnification converting lens capable of switching between an inserted state and an extracted state with respect to an optical axis. The signal processing circuit () composites a mask to an object region of the privacy zone in the image generated by the imaging unit ().

A camera device is provided with an imager that outputs a long exposure signal and a short exposure signal within one field period; a knee processor that compresses a long exposure signal having the luminance level of a knee point or higher at a compression rate (i.e., decreases an inclination of an incident light amount-luminance level line, representing a variation in a luminance level with an amount of incident light); and a knee controller that adjusts the knee point and the compression rate according to a luminance level of a synthesized signal obtained by synthesizing the long exposure signal and the short exposure signal. In this knee control, the knee point decreases with an increase in the luminance level of the synthesized signal, and the inclination is adjusted to approach an original inclination thereof.

In a camera, a sound input unit inputs a monitoring sound obtained from a monitoring place, and an image generation unit generates a monitoring image obtained from the monitoring place. A sound anomaly detection unit then detects a sound anomaly in the monitoring place based on the monitoring sound, and an image anomaly detection unit detects an image anomaly in the monitoring place based on the monitoring image. A comprehensive anomaly judgment unit comprehensively judges whether or not there is an anomaly based on detection results of the sound anomaly detection unit and the image anomaly detection unit. When the comprehensive anomaly judgment unit judges that there is an anomaly, an anomaly notification unit notifies a controllerof the anomaly. An anomaly can be reliably detected by the comprehensive anomaly judgment.
