    摘要: A ceramic arctube preferably for a high pressure discharge lamp. The ceramic arctube can have an anti-reflection interference coating on the outside or inside surface of the bulb section of the arctube. The outside and/or inside surface of the outer wall of the bulb section of the arctube can be substantially spherical to increase efficiency. The wall thickness of the outer wall of the bulb section can be shaped to lens rays from the arc toward a preselected region of a reflector optically coupled to the arctube to increase efficiency.

    摘要: A ceramic arctube for use in a high intensity discharge lamp. The arctube includes a ceramic light transmitting tube which surrounds the arc. The light transmitting tube has two or more features selected from the group consisting of (a) an inner diameter less than 2.6 mm, (b) a wall thickness of less than 1.4 mm, (c) an average grain size of greater than 20 microns or less than 5 microns or real in-line transmission (RIT) greater than 20%, and (d) an inner surface or outer surface having an Ra value less than 100 nm. These features lead to a smaller apparent size of the arc source and less scattering of light, resulting in improved performance of the arctube in a reflector lamp.

    摘要: A method and system to supply current to a high pressure lamp is provided, the method and system comprising an alternating lamp current waveform with a half cycle mean amplitude I1 and a half cycle time duration T, a current pulse waveform including at least one current pulse with a half cycle mean amplitude I2 and at least one current pulse occurring after the trailing edge of a half cycle of the alternating lamp current, the pulse having a half cycle duration of Tp. These waveforms are combined to generate a current waveform including a current pulse waveform, the current pulse waveform starting after a time delay Td from the trailing edge of a half cycle of the alternating lamp current waveform, the time duration Tp of the at least one current pulse lasting less than the remaining time before the leading edge of the second half cycle of the alternating lamp current waveform. The combined current waveform supplies current to a high pressure lamp and produces a cone shaped tip protrusion which reduces lamp flicker.

    摘要: A method of producing a compressed video data stream (12) by compressing a stream of relatively high dynamic range video frames (2). A bilateral filter (3) extracts a base frame (4) with luminance information. The base frame (4) and the original frame (2) are used to provide a detail frame (5) with chroma information. A tone mapping operation (6) is selected (7, 11) and applied to the base frame to generate a relatively low dynamic range base frame (8), which is then compressed (9). The detail frame (5) is compressed separately. Final frame data (12) is then created, consisting of the compressed relatively low dynamic range base frame, the compressed detail frame, and stored information in respect of the tone mapping operation that had been applied to the base frame.

    摘要: A method for increasing dynamic range of original image data representing an image comprises applying an expansion function to generate from the original image data expanded data having a dynamic range greater than that of the original image data and, obtaining an expand map comprising data indicative of a degree of luminance of regions associated with pixels in the image. The method then combines the original image data and the expanded data according to the expand map to yield enhanced image data. Apparatus for boosting the dynamic range of image data comprises a dynamic range expander that produces expanded data, a luminance analyzer that produces an expand map and a combiner that combines the original and expanded data according to a variable weighting provided by the expand map.
