Title: Thinning processing system of binary picture
Inventor: HIRASHIMA KOUJI
IPC: H04N1/393
Filed: 1984-04-18
Abstract: PURPOSE:To perform the uniform thinning at a high speed with simple constitution by preparing two kinds of thinning patterns and by thinning pictures while thinning pattern along with an optimum approximate curve from an original picture is sequentially selected with the aid of the thinning pattern. CONSTITUTION:A control part 1 stores numbers of total application times of two kinds of thinning patterns (u) and (v) in counters I2 and I3, respectively. A digital differential analyzer DDA6 decides the application order of the thinning pattern in accordance with each number of application remaining times of thinning patterns stored in counters 2 and 3. A thinning circuit 7 arbitrarily sets the thinning pattern for storing thinning patterns signaled from the DDA6 in a thinning pattern I memory part 4 and a thinning pattern II memory part 5, and therefore a high speed and uniform thinning can be performed with simple constitution.

Title: Picture contrast adjustment device
Inventor: INAMINE SEIGO
IPC: H04N1/407
Filed: 1993-03-12
Abstract: PURPOSE:To obtain a picture with sharp contrast even in the case of an original including much of tone. CONSTITUTION:An A/D converter converts an analog picture signal outputted from an image pickup element into a multi-gradation digital picture signal. A main correction circuit generates a histogram H1 from the digital picture signal to correct a picture element density distribution area in the histogram H1 so as to spread to the entire picture element density and to generate a histogram H2 whose picture element density distribution is corrected to spread to the entire area. Then gamma correction is applied by a correction conversion circuit to set a point (gravity center) G bisecting the area of the histogram H2 to be a center of the entire density range and then a corrected histogram H3 is generated. Thus, the multi-gradation digital picture signal with excellent contrast is obtained.

Abstract: PURPOSE:To improve responsibility and detection precision by leading out a detection signal, which shows whether a surface printed form contacting and leaving a pressure drum is present on the pressure drum and also shows the prescribed contacting/leaving angle position of the form on the pressure drum, after photoelectric conversion. CONSTITUTION:The form S is wound around a drum part 7 where the pressure drum 3' rotates counterclockwise by a center angle beta from a reference position P, so detection light reflected from the form S is returned to a lead-out optical fiber and made incident to photodetecting elements 17 at photodetectin parts P and Q to turn on pilot lamps. Then, the forms S is clamped by a pawl part C'' of a feed drum 4 where the pressure drum 3' further rotates counterclockwise by a center angle gamma, and the form S is not present near a pawl part C' of the pressure drum 3'. Therefore, no detection light is returned to the lead-out optical fiber 11 and the pilot lamp at a position R is not turned on. Thus, the passing state of the form S at the pressure drum 3' and the position of the pawl part C' are detected successively to improve the response property and precision of the detection.

Abstract: PROBLEM TO BE SOLVED: To improve the response speed of a photorefractive element by controlling the silanol content in a polysilane. SOLUTION: Though a polysilane has hole transferring ability, silanol groups contained in the polysilane act as hole traps and deteriorate the hole transferring ability.

A soln. contg. the polysilane, nonlinear optical dye and sensitizer is freed of the solvent by a means such as heating or pressure reduction to obtain the massive polysilane compsn. This compsn. is held between transparent electrode plates. The objective polysilane photorefractive element is composed of a polysilane compsn. layer 1, transparent ITO electrode layers 2 and transparent substrate layers 3. The element has a remarkably improved response speed.
