Title: Image processing method for certification photograph, and printer for certification photograph
Inventor: TAIMA TAKASHI
IPC: H04N1/387
Filed: 2002-12-19
Abstract: <P>PROBLEM TO BE SOLVED: To make inconspicuous "white stripes" or "stepwise stripes" produced on a print image, caused by irregular transport speed of recording paper unclear.  <P>SOLUTION: From an image data for certification photograph, consisting of a personal image and the background image, background image color is identified after a background image is extracted. Target tone values are then determined for each color. Prevalence for each tone value is determined from normal distribution, produced by dispersing the tone values larger and smaller, such that the target tone values become the mean values. New background image data are obtained by randomly arranging pixels having respective tone values, based on the above prevalence. The new background image data are then composited with the personal image data. Thus, by randomly changing densities on a pixel-by-pixel basis, the background image, having dispersively disposed pixels of various tone values, is obtained, while retaining the apparent tone.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Patent JP-2004512686-A (JP)
IPC: H01L31/10
Filed: 2001-10-12
Abstract: A method in which thin-film p-i-n heterojunction photodiodes are formed by selective epitaxial growth/deposition on pre-designated active-area regions of standard CMOS devices. The thin-film p-i-n photodiodes are formed on active areas (for example n<SUP>+</SUP>-doped), and these are contacted at the bottom (substrate) side by the "well contact" corresponding to that particular active area. There is no actual potential well since that particular active area has only one type of doping. The top of each photodiode has a separate contact formed thereon. The selective epitaxial growth of the p-i-n photodiodes is modular, in the sense that there is no need to change any of the steps developed for the "pure" CMOS process flow. Since the active region is epitaxially deposited, there is the possibility of forming sharp doping profiles and band-gap engineering during the epitaxial process, thereby optimizing several device parameters for higher performance. This new type of light sensor architecture, monolithically integrated with CMOS, decouples the photo-absorption active region from the MOSFETs, hence the bias applied to the photodiode can be independent from the bias between the source, drain, gate and substrate (well) of the MOSFETs.
