Title: Image data transmission system
Inventor: NAKAO MASAFUMI
IPC: H04N19/503
Filed: 2004-12-27
Abstract: <P>PROBLEM TO BE SOLVED: To provide a compression technology appropriate to transmission of, particularly, image data.  <P>SOLUTION: Upon the receipt of image data (0 to 255), a gradation conversion means 2 converts the expression of the gradation of the data into positive/negative data relative to a halftone (128) expressed in "0". A mantissa/exponent separation means 4 receives the converted image data to separate the converted image data into exponent part image data and mantissa part image data. A mantissa part compression means 8 compresses the mantissa part image data into compressed mantissa part image data. Further, an exponent part compression means 10 compresses the exponent part image data into compressed exponent part image data. A transmission means 10 transmits the compressed mantissa part image data and the compressed exponent part image data. In this case, the transmission means 10 transmits the compressed exponent part image data preferentially to the compressed mantissa part image data. Thus, it is possible to attain a progressive processing wherein an image with a rough contrast is transmitted earlier and then an image with a detailed contrast is transmitted later.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

IPC: H01L31/032
Filed: 2003-11-24
Abstract: According to a similar known method, the light of a light coherent source is transmitted to the surface of an actual layer, and a back scatter which is diffused by a microroughness and varies with respect of a growth is detected with the aid of a detector, thereby making it possible to define a time-dependent relation for a process by means of intermediate singular points. Said known method without a spatial resolution is however usable only for fixed substrates. The inventive method for continuous co-evaporation processes mainly used for thin chalcogenide layer engineering for solar cells. Said method consists in cyclically and continuously guiding a visible light beam (VLB) to a movable substrate (S) at a speed significantly higher than the moving speed of the substrate (S). Back scattered light is detected on the surface of the actual layer according to the incidence point thereof. The local profile of the diffused light is defined by allocating of the measured singular points (1, 2, 2a, 3, 4) to a known deposition process. Said profile makes it possible to anticipate the quality of the layer at any moment and place of the deposition process, thereby making it possible to adjust in situ spaces by modifying the corresponding parameters of the process.
