Patent ID: 8670024

Claim:
A camera system having a digital camera, in particular a digital motion picture camera, for taking images, wherein the camera includes a camera objective ( 10 ) having a mask ( 18 ) with a plurality of masking sections ( 20 ) which are permeable for radiation of a first spectral range and are impermeable for radiation of a second spectral range different from the first spectral range; and wherein the camera includes an optoelectronic sensor arrangement ( 26 , 26 a , 26 b ) having a plurality of sensor elements ( 36 a - 36 d ) for generating exposure-dependent received signals which form a respective image; wherein the plurality of sensor elements ( 36 a - 36 d ) includes a first group of sensor elements ( 36 a - 36 c ) for generating received signals in dependence on radiation of the first spectral range, but not of the second spectral range, and a second group of sensor elements ( 36 d ) for generating received signals in dependence on radiation of the second spectral range, but not of the first spectral range, wherein the sensor arrangement includes two separate sensors ( 26 a , 26 b ), wherein a first sensor ( 26 a ) includes the sensor elements of the first group of sensor elements and a second sensor ( 26 b ) includes the sensors elements of the second group of sensor elements, wherein a beam splitter ( 24 ) is arranged between the camera objective ( 10 ) and the two sensors ( 26 a , 26 b ) and is designed to direct a portion of radiation passing through the camera objective ( 10 ) to one of the two sensors ( 26 a , 26 b ) and to direct another portion of the radiation passing through the camera objective ( 10 ) to the other of the two sensors ( 26 a , 26 b ), wherein the camera system furthermore has an evaluation unit ( 34 ) which is made to determine a depth value for a respective picture element or a partial picture region on the basis of a blur of an image taken by the second group of sensor elements ( 36 d ), wherein the first spectral range is formed by at least one spectral range of visible radiation, and wherein the second spectral range is formed by at least one spectral range of non-visible radiation, wherein the camera objective ( 10 ) comprises a diaphragm ( 16 ), and wherein the mask ( 18 ) is arranged within the diaphragm ( 16 ) of the camera objective ( 10 ) or directly adjacent to the diaphragm ( 16 ) of the camera objective ( 10 ), wherein the mask ( 18 ) has passage sections ( 22 ) which are complementary to the masking sections ( 20 ) and which are permeable both for radiation of the first spectral range and for radiation of the second spectral range.
