Abstract
In order to ascertain what a person really sees, a monitoring, picture recording system has at least one video camera ( ) arranged in such a way that the captured images at least approximately match the field of vision observed by the person. For that purpose, at least one eye parameter, such as the viewing direction and/or the refractive power of at least one eye ( ), is determined and the picture recording monitoring system ( ) is controlled depending on the thus determined parameters. The position of the center of the pupil is determined by image sensors ( ) associated to the eyes and the visual axis is derived therefrom. At least one video camera ( ) secured in an adjustable manner to the head is oriented according to the visual axes. Focusing may also be adjusted depending on the refractive power of the eye. The parallel capture of visual information may be used in many fields, in particular for monitoring tasks and also for therapeutic uses.
