Abstract
A camera system for a vehicle has an image acquisition unit (2) having an image sensor (4), an optical element (3) and at least one IR-blocking filter (5) for acquiring image data of an object, a processing unit processing the image data acquired from the image acquisition unit (2) for displaying the object (7) on a display unit (9), and at least one illumination unit (10) for illuminating the object (7) with light (12) having a wavelength at least partly within the upper region (13) of sensitivity of the human eye and at least partly below the blocking limit of the IR-blocking filter (5).
Claims9
A camera system for a vehicle comprising:
- an image acquisition unit comprising an image sensor, an optical element and at least one IR-blocking filter for acquiring image data of an object;
- a processing unit processing the image data acquired by the image acquisition unit for displaying the object on a display unit;
- and
- at least one illumination unit for illuminating the object with light having a wavelength entirely within or partly below the upper region of sensitivity of the human eye comprising the range between about 680 nm to about 780 nm and entirely below or partly below a blocking limit of the IR-blocking filter,
- wherein below the blocking limit the IR-blocking filter is 100% IR-transmissive in the range from 380 nm to 730 nm and not IR-light transmissive in the remaining range of wavelength.
