Abstract: A camera with an objective and a sensor serving as an optoelectronic transducer is known in prior art. Said camera can be used, for instance, to monitor traffic in a vehicle or to assist during reverse driving. Conventional CCD sensors have limited brightness dynamics thus making it necessary to provide a controllable diaphragm or a brightness control device for the objective. Novel semiconductor sensors have substantially higher brightness dynamics in the range of 120 dB and can utilize all brightness values occurring in practice without a controllable diaphragm. In a camera having no controllable diaphragm, the entire amount of light always hits the objective. In the presence of intensive brightness, this causes considerable scatterings and reflections and ghost images in the resulting picture. The invention aims at making it possible to achieve practically no disturbing reflections even when no controllable diaphragms are used. This is achieved by combining a sensor (5) having a non-linear conversion characteristic curve (W) and high brightness dynamics and an objective having means for reducing reflections and scattered light. Said means consist, for instance, of an optical gel (8) mounted between the components of the objective or a special configuration of the lens (2, 3) and/or the holder (1) receiving the lens.
