The invention relates to a device for improving the visibility conditions in a motor vehicle, having a radiation source for infrared radiation for irradiating the surroundings of the vehicle, having an infrared-sensitive camera for taking images of at least part of the irradiated surroundings, having a display unit for displaying collected image data, and having a control unit for controlling the device. In this context, the control unit is embodied in such a way that the display is switched off after a time period t which is selected as a function of the collected image data has expired. The camera is preferably selected in such a way that it is sensitive in the range of visible light. The time period t is preferably selected as a function of the brightness values and/or the contrast values of the collected image data. This device ensures very reliable operation for the user.
