An iris authentication apparatus includes a camera for obtaining the image of an eye; a display panel arranged on the same plane as where the lens of the camera is arranged; and guide character generation means, wherein a guide character is displayed on a display panel, and the eye of a person to be authenticated who watches the guide character is guided. As a result, a satisfactory iris image can be obtained by the iris authentication apparatus of one camera type that does not have a zooming function, so that the iris authentication apparatus that can be mounted to a small body, such as a portable telephone, can be provided.

The present invention aims to expand a range through which a guiding visible light for guiding a position of an eye appears in shooting an image of the eye and to put easily the position of the eye onto an optical axis of an imaging optical system in shooting. In the present invention, an eye image pick-up system (10) includes a lens (13), a lens-barrel (12) for supporting the lens (13), a mirror (14) as a guiding mirror for turning an optical path of an imaging optical system at an almost right angle and guiding a guiding visible light, an imaging device (16) for picking up an image of an eye (11), and an LED (15) provide at the back of the mirror (14) on a prolonged line of an optical axis (17) extending from the lens (13) to the mirror (14) to emit the guiding visible light. The mirror (14) has a reflecting film (18) formed by depositing reflecting material onto a transparent substrate, and a circular-ring light guiding portion (19) made of transparent material. The guiding visible light from the LED (15) is guided to pass through the light guiding portion (19) and arrives at the eye (11) via the lens (13). Full circular-ring guiding visible lights are viewed when the position of the eye (11) is put onto the optical axis (17), and the circular-ring guiding visible lights a part of which is lost are viewed when the position of the eye (11) is out of the optical axis (17).

In a monitor camera system capable of understanding a direction, a monitor camera follows, through a picture taken by the monitor camera, the monitor camera makes 360-degree pan rotation and 180-degree tilt rotation, and generates image data in which a character representative of a photographing direction (for example, north) of the monitor camera is superimposed on a picture taken by the monitor camera. Accordingly, the monitor camera provides a picture in which the photographing direction indicating character appears. This enables an operator to easily understand the camera direction through the monitor picture, thus achieving efficient and accurate camera manipulation.

To provide a security camera system for displaying a picture so as to easily know a place where an abnormal situation occurs. The security camera system includes a security camera 61 having at least more than one rotation axis and a controller 70 for controlling the security camera 61. The controller 70 is provided with a moving picture detector 80 for detecting a motion from pictures taken by the security camera during an automatic monitoring operation. The controller switches an operation of the security camera from automatic monitoring to still monitoring in the case when the moving picture detector detects a motion from monitored pictures. Therefore, in the case when a suspicious person, fire smoke, or the like is detected in a subject building at night, for example, during an automatic monitoring operation for shooting target monitoring places sequentially, a shooting point of the security camera is fixed there so as to shoot and display an abnormal situation on a monitor screen.

A single video camera is installed on a vehicle body. Two still pictures of an obstacle are obtained at different vehicle traveling positions. A picture memory stores the obtained still pictures. A feature point extracting section extracts at least one feature point from the data of the stored still pictures. A three-dimensional coordinate data calculating section calculates the distance from the vehicle body to the feature point and the height of the feature point based on the positional data of the feature point on the screen and the vehicle traveling distance data. A stereoscopic picture forming section forms a stereoscopic picture image of a detected obstacle based on three-dimensional coordinate data of the feature points. A monitor displays a plan view or a side view showing the relationship between the vehicle body and the obstacle, thereby allowing a driver to directly grasp the distance of the obstacle. When the obstacle is located within a predetermined distance from the vehicle body, the driver is cautioned against a predictable collision by the alarm sound or related image.

In an imaging apparatus with rotary table having a plurality of control items, operation completion of control items, such as horizontal angle, vertical angle, zoom and focus, of the imaging apparatus and the rotary table is detected by respective completion detectors and so on. On the basis of the logical product of all operation completion signals, an AND circuit 3 permits control toward the next desired value.

A surveillance camera device is provided which has an impact absorbing structure. The camera device includes a rotary base supporting a camera unit, a rotary bracket supporting the rotary base, and coil springs. The coil springs work to elastically urge the rotary base away from the rotary bracket to as to permit the rotary base to move straight against the mechanical pressure of the springs when subjected to a damaging impact on the device, thereby absorbing the impact to avoid damage to the camera unit.

A pivoting unit pivots a video camera at a pivoting speed. The video camera includes a zoom mechanism and a zoom amount signal generation circuit for generating a zoom amount signal. A pivoting speed command signal generating circuit responsive to an operation generates a pivoting speed command signal and a speed controlling circuit controls the pivoting speed in accordance with the zoom amount signal and the pivoting speed command signal. Controlling is made such that the pivoting speed is relatively decreased from the pivoting speed command signal when the zoom amount signal indicates a telephoto side and is relatively increased from the pivoting speed command signal when the zoom signal indicates a wide-angle. A joystick generating the pivoting speed command signal includes two coil springs for generating a reaction force which is made stronger when the operation angle of thereof exceeds a reference. The pivoting speed is also accelerated when the operation angle exceeds the reference.

In a monitor camera system includes a monitor camera capable of rotation 360 degrees in pan directions and 180 degrees in tilt directions and a control unit for controlling the monitor camera remotely, the control unit sends control data indicative of a photographing position or photographing direction of the monitor camera to said monitor camera, while the monitor camera receives the control data to calculate, on the basis of the control data, a pan rotation quantity and a tilt rotation quantity by which the monitor camera is to be rotated from the present camera position, thus accomplishing its pan rotation or tilt rotation according to the calculated rotation quantity. Accordingly, with this configuration, an operator can align the monitor camera in a target direction by merely manipulating a joystick in the target direction, that is, can face the monitor camera to a target position through a simple manipulation. Additionally, this configuration makes it unnecessary for the operator to understand the present camera direction.
