Zusammenfassung: | Acquisition device, more particularly for use in a motor vehicle (13), for acquiring an image having a plurality of pixels with respectively assigned brightness information and assigned depth information, comprising a detector device (2), a lighting device (20) and a control device (1), wherein the control device (1) is designed for providing a modulation signal (12) for controlling the detector device (2) and the lighting device (20), and wherein the detector device (2) is designed for acquiring the depth information depending on the modulation signal (12) and a time-dependent illuminance of a region of the detector device (2) that is assigned to the respective pixel, wherein the lighting device (20) comprises at least one first and one second luminous element (3, 4, 5), the luminances of which are jointly modulatable depending on the modulation signal (12), wherein the modulation amplitude of the modulation is predefined separately for the first and second luminous elements (3, 4, 5) depending on a first and second amplitude signal (9, 10, 11) that can be provided by the control device. In this regard, when overillumination of an image region is detected, the amplitude of the modulation of one or a plurality of the luminous elements can be reduced in order to decrease the brightness in the corresponding image region. Correspondingly, for underilluminated image regions, the amplitude of the modulation of one or a plurality of luminous elements can be increased. |
