Patent ID: 7391456

Claim:
A digital motion picture camera, at least comprising an optoelectronic sensor device ( 31 ) for the recording of motion pictures, with the optoelectronic sensor device having, in an areal arrangement, a plurality of sensor elements ( 53 , 55 , 57 ) for the generation of a respective received signal in dependence on a light exposure; a control device ( 45 , 47 ) for the control of the read-out of the received signals of the sensor elements, with the optoelectronic sensor device ( 31 ) being controllable by means of the control device ( 45 , 47 ) for the recording of the motion pictures at a pre-settable variable picture recording frequency; a digitizing device ( 35 ) for the digitizing of the received signals of the sensor elements; an optical viewfinder ( 27 , 29 ) for the visual observation of the motion pictures to be recorded; and a rotationally movable mirror diaphragm ( 15 ) which is disposed upstream of the optoelectronic sensor device ( 31 ) and by means of which a received beam path ( 13 ) can be divided at least into a recorded beam path ( 19 ) for the optoelectronic sensor device and a viewfinder beam path ( 21 ) for the optical viewfinder, wherein the control device modifies the frequency at which the received signals of the sensor device are read out, in order to vary the picture recording frequency, and matches the rotational frequency of the rotationally movable mirror diaphragm ( 15 ), in order to bring about an exposure or a masking of the sensor device at a reduced or increased rate.
