Abstract
A camera comprises a sensor such as a CCD or ICCD for receiving radiation representative of a scene, a filter such as an arrangement of parallel neutral density stripes, arranged to attenuate the radiation reaching the sensor, and decoding electronics such as comb filters which decode the encoded video output of the sensor, to produce a compressed video image, from which the pattern of the filter has been removed.
Claims15
A camera, comprising:
- a sensor for receiving radiation representative of a scene;
- filter means for attenuating the radiation reaching different spatial regions of the sensor to different extents;
- and decoding means for combining contributions to an output of the sensor from the different spatial regions, to produce a camera output representative of lines of an image of the scene of extended dynamic range, the filter means comprising stripes orientated so that lines of the stripes are inclined to the lines of the image, the decoding means being operative for removing a pattern of the stripes from the output of the sensor.
