Abstract: The invention aims at providing low-cost iris image pickup apparatus for picking up iris images at a high accuracy.

Abstract: A monitoring camera apparatus includes: a video camera; a panning mechanism; and a tilting mechanism; and automatic pivoting portion for operating the panning mechanism to pan the video camera by a predetermined pan (tilt) angle or to a predetermined pan (tilt) angle position when the video camera reaches the predetermined vertical (horizontal) position and a tilt command is inputted. The predetermined vertical position may be determined when the video camera directs the downward in the vertical direction. The auto-pivoting function may be started in response to both predetermined pan and tilt positions. During the auto-pivoting, controlling the video signal processing is stopped, pan and tilt speed is set to maximum, the direction of panning may be judged when the predetermined angle position is set. After auto-pivoting, tilt is made upwardly though the tilt command indicates downward and the screen image may be inverted and the pan and tilt positions are held until pan (tilt) command is inputted.

Abstract: Monitor camera units, a data storing unit, a control server, a monitor display are coupled by a network. The monitor camera unit includes a motion detector for detects a motion from video data, a microphone, a traffic monitor, a memory for storing the video data, a sensor signal input circuit. The traffic monitor monitors the traffic of the network. If the traffic is high, only necessary data or sound data is transmitted. The memory stores the video data in response to the motion detector and a thinning circuit thins the video data from the memory in response to a sensor signal. The control server receives the alarm data from the monitor camera and further receives the alarm type data, time data, position data of a pivoting unit for pivoting the camera unit and transmits the data to the display terminal. In the presence of a loud sound, alarm data is also generated but it is not sent if a switch is OFF. The control server includes a data base storing set of alarm data.

Abstract: A television camera equipped with a continuously-variable-speed electronic shutter function which can control the charge-storing time of a solid-state image sensor and an amplifier so that a video signal follows the optimum light amount for a subject at high speed and with high accuracy. A shutter-equipped image sensor which is controlled by a shutter pulse generating unit, converts light incident on an optical lens into an electric signal. The electric signal, after being passed through an amplifier and a signal processing unit, is detected by a video level detecting unit as a video level. A shutter control unit holds the shutter amount corresponding to the video level for each field to immediately calculate an estimated shutter amount by using a predetermined equation, and supplies the calculated shutter amount to the shutter pulse generating unit for each field. A control mode decision unit exclusively controls a gain control unit serving as an AGC and the shutter control unit.

Abstract: A video camera specifies as a photometric area any block of a field of image to be picked up and picks up a subject to be seen by optimizing the amount of light regardless of the position where a television camera is located. The video camera comprises a solid-state image pick-up element (CCD), a display device and devices for controlling the diaphragm of a lens. In operation, the image picked up by the solid-state image pick-up element is divided into plural blocks to be displayed. Any block of these plural blocks can be specified as a photometric area. The amount of light for the photometric area is calculated and the diaphragm of the lens is controlled so that the subject can be seen by optimizing amount of light.
