Abstract: PURPOSE:To accurately determine the quantity of exposure by extracting a main image area and a background image area from images recorded on an original picture and independently extracting an image feature value from respective area to calculate the quantity of exposure. CONSTITUTION:For example, average red density, average green density and average blue density in the areas are used as the image feature values, a value obtained by adding respective color density values of respective picture elements and dividing the added value by the number of picture elements or an intermediate value between the maximum color density and the minimum color density is used as the average color density and a color correcting value Ci and a reference exposure value Di are calculated based on the found average color density. The obtained exposure value Di' is sent to a filter adjusting part 19, a color filter having complementary relation to the corresponding color is extracted stepwise from a reference position or inserted further into the center of an optical path 20, so that the quantity of insertion of the color filters 16-18 into the optical path is adjusted in stages and three color light components for printing color can be adjusted. Components which can not be corrected by the color filters 16-18 are sent to a shutter control part 27 to increase/decrease the exposing time of the shutter 25 properly.

Title: Information reader
Inventor: TAKIMOTO SHIGERU
IPC: G03B27/32
Filed: 1989-02-09
Abstract: PURPOSE:To smoothly eject a defective original by setting the carrying speed of an original in the eject part of an ejecting means upwardly ejecting an original after it passes through a reading position higher than the carrying speed in a reading position. CONSTITUTION:When the original 1 is set to a paper feeding tray 2, it is carried by a paper feeding roller 4 between a overlapped carry detecting roller 5 and an accompanied carry detecting roller 6 with the delay of the prescribed timing. If the original is judged to be overlapped carry or accompanied carry, it is sent by carrying rollers 13a to 13c to a solenoid 19 as a defective original. A carrying path 20 is changed upward by the expanding action of the solenoid 19, and the defective original is carried until it abuts on the nip part of ejecting rollers 21a and 21b. Since the diameter of a driving pulley 23 is less than that of a pulley 15a, the speed of revolution of the ejecting roller 21a is lower than that of the carrying roller 13a. Thus, the defective original is ejected to a defective original tray 22 without being jammed between the ejecting rollers 21a and 21b.

Filed: 1983-02-23
Abstract: PURPOSE:To improve noise characteristic of a gain control circuit by connecting a variable element to an emitter of a transistor (TR) having an amplification function so as to control the amplitude while amplifying the signal. CONSTITUTION:A resistance value of a diode 4 connected to the emitter of TRs 2, 3 is changed by a voltage applied to a bias voltage terminal 11 and a cur rent feedback amount is changed so that the gain between an input terminal 10 and an output terminal 12 is controlled. Further, since the impedance of the diode 4 is changed continuously against the continuous change of a voltage applied to the terminal 11, the gain between the input terminal 10 and the output terminal 12 is controlled continuously. Thus, since the amplitude is controlled while amplifying the signal, excellent noise characteristic is attained.
