Title: Color correction method for color picture signal
Inventor: NAKAGAWA TSUTOMU
IPC: H04N1/48
Filed: 1989-02-14
Abstract: PURPOSE:To surely correct the color with high accuracy even when a color space of the color reproducing system is narrow or wide by correcting the difference from the color reproduction in the different system over the entire color space. CONSTITUTION:Lots of color patches able to express each color reproducing area of two kinds of different color reproducing systems are generated corresponding to the data of each system in the case of forming a color picture from a color signal being a digital data, they are measured by a substantially common measuring instrument (such as color meter or densitometer) to form a color space for each system. When one color space is narrower than the other color space, the color space is reproduced with a signal over a limit able to be reproduced by the system forming the narrower color space thereby expanding the color space virtually. Then the relation of data corresponding the measurement in each color space is obtained, the color signal of the 1st system is converted by the relation of correspondence to apply color correction and the color reproduced by the 2nd system is formed to a desired color. Thus, both the reproduced colors are surely matched.

Abstract: PROBLEM TO BE SOLVED: To remove toner residue and a foreign matter, etc., adhering to the surface of a transfer roller by cleaning the surface of the transfer roller while a cleaning roller is rotating in a state that it comes in contact with the transfer surface of the transfer roller. SOLUTION: While the cleaning roller 210 is rotated in tight contact with the outer peripheral surface of the transfer roller 124, a toner image formed on a photoreceptor belt 110 as an electrostatic latent image is transferred to the roller 124 and printed as the image on printing paper 126 in a state where the roller 124 made nearly half rotation, and then the remaining toner residue is removed. In such a case, the remaining toner residue adheres to the outer peripheral surface of the roller 210 due to the difference of surface energy between the rollers 124 and 210. It is desirable to produce the roller 210 of metallic material excellent in heat conductivity, and a heat source 211, for example, a heater lamp is installed around a rotary shaft so as to transmit the generated heat to the outer peripheral surface of the roller 210.
