Automobile infrared night vision device and automobile display
First Claim
1. Automobile display unit for representation of image data of a night vision device including an image processing unit, to which image data is supplied, and which is adapted for processing the image data supplied to it such that contiguous areas of image data are determined, of which the image points exhibit a greater lightness than a predetermined lightness threshold value, the image data of the image points of these contiguous areas are replaced by image data, which exhibit at least a partially reduced light intensity value, a display for representation of the image data supplied by the image processing unit, and a control unit for controlling the display unit thereby characterized, that the image processing unit includes a unit for determining a central area and an edge area of the contiguous areas and is adapted for assigning the image points of the central area image data with reduced lightness, in comparison to which the image points of the edge area of the image data are assigned light intensity values which are different therefrom.

Abstract
The invention concerns an automobile display unit, an automobile infrared night vision device and an automobile with such a display unit or, as the case may be, with such an infrared night vision device. The display includes an image processing unit which processes the image data supplied to it such that contiguous areas of maximal light intensity are recognized and these image data are adapted to the extent that they are at least partially replaced by image data with reduced light intensity values. These changed image data are supplied to the display, which reproduces these image data. This display unit makes possible a reduction or a prevention of blinding by brilliant light, which is particularly disturbing in a case of display of infrared night vision image information.
