Abstract: PURPOSE:To perfectly jump the proper color of an original without inviting the deterioration of the quality of a picture by jumping even the proper color (density) which could not be jumped perfectly by correcting the output level of a corrected picture signal. CONSTITUTION:The ON/OFF signal of an original irradiating lamp 8 is outputted to a lamp regulator 21c from a CPU 21a. At the time of controlling the original irradiating lamp 8, if the quantity of light larger than the maximum quantity of light of the original irradiating lamp 8 is required in order to jump the proper color, the AE correction processing of two stages is performed. Namely, first AE correction processing is performed by irradiating the original by the maximum quantity of light by letting lighting voltage of the original irradiating lamp 8 be maximum. Next, second AE correction processing to jump the proper color of the density from 1m to 1h by changing a shading compensating coefficient is performed. Namely, when the proper color of the original can not be jumped perfectly even though the original irradiating lamp 8 is adjusted to the maximum quantity of light, the remaining proper color (density) is jumped further by shading compensating correction or gamma correction as well.

Title: A/d converter device
Inventor: YAMAGUCHI TSUTOMU
IPC: G06F3/05
Filed: 1994-08-09
Abstract: PURPOSE:To enable digital conversion of an input A.C. signal to be executed at a lower sampling clock Fs by setting Fs to make prescribed relation among one cycle portion fetched from an A.C. signal Fm, the number N of pieces of data and the sampling clock Fs. CONSTITUTION:A comparator 15a receives the A.C. signal Fm to convert it into the square wave of 50% duty ratio. Control is executed to permit the frequency of a signal obtained by frequency-dividing the oscillation frequency of an oscillator by N to match that of the signal Fm in a PLL circuit 15b and the original frequency of an internal oscillator, which is transmitted from the circuit 15b, becomes N.Fm. A frequency divider circuit 15c frequency-divides the output frequency N.Fm of the circuit 15b by (WN+1) and gives it to an S/H circuit 12 as the sampling clock Fs1. The circuit 12 sample-and-holds the level of the signal Fm at the rising of the clock. It takes a little time to make a hold voltage stable when the circuit 12 samples and holds the signal Fm. Therefore, Fs2 is made behind Fs1 by a phase shift circuit 16 in order to execute digital conversion after the delayed time elapses.
