PAN-TILT CAMERA
The present invention relates to a pan-tilt camera comprising a camera head (102), a stationary unit (106), an intermediate member (104) arranged between the camera head (102) and the stationary unit (106), a first rotary joint (108) rotatably connecting the camera head (102) to the intermediate member (104), a second rotary joint (112) rotatably connecting the intermediate member (104) to the stationary unit (106), a communication path between the camera head (102) and the stationary unit (106), the communication path including an optical waveguide (116) arranged between the camera head (102) and the stationary unit (106), the optical waveguide (116) having a first end (118) and a second end (120), the first end (118) being positioned at the first rotary joint (108) and being arranged to receive light from the camera head (102) through said first rotary joint (108), and the second end (120) being positioned at the second rotary joint (112) and being arranged to send light to the stationary unit (106) through said second rotary joint (112). Further, the pan-tilt camera includes an image processing unit (314) arranged in the stationary unit (106), said image processing unit including a color interpolator (330) arranged to perform a first color interpolation of the image data from the image sensor (304).
