摘要： PROBLEM TO BE SOLVED: To provide a device for monitoring the monitoring range by using at least one camera, wherein a controller is composed so as to detect a shadow of the minimum range of a bright color partial stripe and/or a dark color partial stripe as a shadow obtained when an object target intrudes into a monitoring range.
SOLUTION: The controller is configured so as to detect a shadow existing in a frame perpendicular to a contrast stripe 12 within an image of a camera 4, that is, a shadow which falls below the least number of bright color pixels between the start point Y2 of the bright color and the end point Y3 of the bright color of a bright color partial stripe existing in the frame and/or the second least number of dark color pixels between the start point Y1 of a dark color and the end point Y2 of the dark color of a dark color partial stripe 14 existing in the frame as a shadow obtained by damaging a mark of the contrast strip 12 and with a shadow of the smallest range as a shadow of the specified number of adjacent frames.

摘要： PROBLEM TO BE SOLVED: To provide a method for triggering of image recording of a camera device by means of an image recording surface itself as a triggering sensor instead of providing an additional sensor. SOLUTION: At least a part of the image recording surface of the camera device is acted on by at least one radiation source in a non-recording state, a signal thereby derived from the image recording surface is supplied to an evaluation device and is evaluated as a non-recording signal and, upon change of the non-recording signal, the image recording is triggered automatically. Thus, the image recording is triggered by at least one camera device and the image recording surface is used as the triggering sensor so that the additional sensor is not required.

摘要： PROBLEM TO BE SOLVED: To immediately assist a special action, for example, trigger of an alarm signal or switch-off of machine according to the detection of an object advancing to a protective zone. SOLUTION: This monitoring method for protective zone comprises transmitting one beam in the direction of the protective zone by a device, receiving the beam reflected/returned by the object arranged in the protective zone, and quantitatively determining the distance between the device and the object. Otherwise, this method comprises transmitting at least two beams having an angle between the both; receiving a first beam reflected/returned by the object when the object is present in the protective zone; receiving a second beam reflected/ returned from a position arranged out of the protective zone when no object is present in the protective zone; and arranging the device so as to be capable of quantitatively determining both the distances to the object and the second position from the device. This monitoring device is applied to this monitoring method.

摘要： PROBLEM TO BE SOLVED: To make it possible to improve the suppression of stary light in stable light by a method wherein individual photosensitive elements are equipped individually with stray-light suppression circuits. SOLUTION: In a light receiver unit at a photoelectron-sensor array which transmits optical pulses to an object and which receives their reflection, a plurality of cells which are provided with photosensitive elements formed as photodiodes 1 are arranged in a row or in a matrix. A potential point P which is common to every photodiode 1 and to a current source 2 is connected to the input of a regulating device 3, and its output is connected to the regulating input of the current source 2 via parallel filters 4, 5. The potential point P is maintained at an applied voltage Vref independently of the amplitude and the frequency of environmental light while operating light is suspended. When the operating light is received, switches 6, 7 are operated by a control signal SE, an electric-charge difference which corresponds to the component of the operating light is generated in a capacitor 8, it is supplied to a sample-and-hold circuit 12 by a switch 10 which is excited when an address is designated, it is stored as a difference signal, and a prescribed processing operation is performed further.
