The invention relates to a method for generating a computed digital image of a scene, which can be illuminated with different luminous intensities at a first illumination angle by a first light source. An image sensor records a number of individual images of the scene under different lighting conditions, and these images are set against one another in a pixel-by-pixel manner in a data processing device in order to generate a resulting image. The invention is characterized in that at least one additional light source is provided by means of which the scene can be illuminated at an illumination angle that is different from the illumination angle of the first light source. The different lighting conditions when recording the individual images are obtained by various combinations of luminous intensities of the first and of the at least one other additional light source. The invention also relates to a device for carrying out the inventive method.

Method and device for compensating for shadows in digital images

A method for operating a spatial-resolution opto-electronic sensor device is provided. In order to produce a computed image of the surroundings, the sensor surface is activated as a sequence of n-tuples of pairs from activation intervals and assigned subsets of sensor elements in such a way that, within an n-tuple, n subsets of sensor elements are activated during n activation intervals under different lighting conditions for the surroundings caused by appropriate control of the lighting source, and fields recorded within an n-tuple are processed with one another in a data-processing device.

Method for operating an optoelectronic sensor device

A method and apparatus for monitoring the interior space of a motor vehicle by means of IR radiation include at least one stationary IR transmitter and at least one stationary IR receiver arranged in a central position in the vehicle interior space. The interior space is at least temporarily irradiated. The reflected IR radiation is received by an IR camera as IR receiver. For suppression of interfering effects two images of the same object are recorded at different illumination levels. The two images are subtracted from one another with respect to their gray scale values.
