ABSTRACT:
The automatically operated door is controlled in dependence upon the presence and movement conditions of one or more persons present on a support surface within a predeterminate space on a predetermined side of the automatically operated door. A radiation source, particularly an infrared radiation source emits a radiation field along and at a predetermined height above the support surface so that the at least one person present on the support surface is irradiated and infrared reflections originate from the at least one irradiated person. The infrared reflection is received at an active imaging device such as, for example, an infrared camera. Such imaging device contains a liquid crystal display (LCD) unit with an associated microshutter and a linear image sensor arranged in a plane extending substantially parallel to the plane of the liquid crystal display unit. Data representative of the infrared reflection images are processed in a programmable evaluation and control unit with respect to the contour representative of the at least one person and with respect to temporal variations in the reflection images. The recognition capability of the apparatus can be improved by alternatingly producing optical reflection images and infrared reflection images.
