Title: System for inputting picture
Inventor: ISOBE YUJI
IPC: H04N1/41
Filed: 1987-08-20
Abstract: PURPOSE:To output an image which looks approximately equal to a former variable-density picture by converting the digital picture data of an N gradation to the data of an M gradation smaller than the N based on the appearing frequency of respective gradation levels, quantizing them to be binary with a dither method and obtaining a dither picture. CONSTITUTION:By using a variable-density histogram stored in a work memory 16, a logarithmic gradation conversion is executed, and thereafter, the dither picture is obtained. The data necessary for executing such a logarithmic gradation conversion are stored in a program memory 15. Consequently, an image processing circuit 11 executes the logarithmic gradation conversion by using the variable-density histogram in the memory 16 obtained through a bus 17 and using the data in the memory 15, and, for example, digital picture data gradation-converted from N=256 to M=64 are obtained. The memory 15 quantizes multivalue data to binary data by the dither method and stores also data for a dither expression necessary for obtaining the dither picture data. Then, the circuit 11 uses the data for the dither expression in the memory 15 and quantizes the digital picture data of 64 gradations to binarizing data.

Abstract: PURPOSE:To form the titled high-quality polycrystalline silicon with little unevenness on its surface by producing the polysilicon layer by chemical gas-phase growth technique and subjecting that polysilicon layer to a heat treatment at 1,000Angstrom  or more after heat diffusion of phosphorus. CONSTITUTION:A polysilicon 1 is produced on an Si substrate 4 by chemical gas-phase growth technique at about 600 deg.C. At this stage, there is no polysilicon grain having a diameter over a few hundreds Angstrom . After that, the polysilicon is exposed to the atmosphere of a gas including phosphorus, e.g., phosphorus oxytrichloride to diffuse phosphorus. Then, polysilicon grains grow and increase their diameters. Furthermore, when the polysilicon is subjected to a heat treatment in an inert gas at 1,000 deg.C or more, the phosphorus existing in a grain boundary diffuses into a polysilicon grain and their diameter further increases. Accordingly, the unevenness on the surface of the polysilicon decreases and the polysilicon of better quality can be produced.
