A digital motion picture camera, 11, for taking a sequence of moving images comprises a rotating mirror sector shutter, 15, which alternately transmits (via a translucent sector of the shutter, 27) a received optical path, 25, of the motion picture camera as a first imaging optical path, 31, and deflects (via a reflecting sector of the shutter, 29) the received optical path as a second imaging optical path, 33. A first image sensor, 17, is located in the first imaging optical path and a second image sensor, 19, is located in the second imaging optical path. The image sensors may be sensitive in different spectral ranges such as visible light and infrared radiation. The camera may further comprise a illumination means (Figure 3, 39) that emits radiation of a wavelength that is contained in one of the spectral ranges such that it can be detected by only one of the image sensors. |
