Abstract: PURPOSE:To especially improve the reproducibility of a dark part when gradation is expressed on a recording medium by altering dark time digital data according to the change of an amplification degree, and correcting the digital data from a photoelectric converting sensor by means of the altered dark time digital data. CONSTITUTION:The change of the illuminance of an illumination light is detected by an amplification degree regulating circuit 6 as the change of a reference white level outputted from a photoelectric converting sensor 1, the amplification degree regulating circuit 6 sends an amplification degree regulating signal to an AGC amplifier 2 so that the white level may be set at a prescribed constant value, and sets the amplification degree of the AGC amplifier 2 at a new value. Correspondingly, the multiplier of a multiplying device 7 is altered, and the value obtained by multiplying the multiplier by the changing ratio of the amplification degree of the AGC amplifier 2 is made into the new multiplier. The dark time digital data multiplied by the new multiplier are converted into an analog signal voltage by a D/A converter 8, applied to a reference voltage terminal Vref of an A/D converter 3 as the new reference voltage, and the digital data can be highly accurately corrected.

Filed: 1986-11-13
Abstract: PURPOSE:To measure how many times the input data of an unvarying value, i.e., a constant code, is inputted by supplementing a selector and an OR gate. CONSTITUTION:When a WRITE pulse (a) arrives at a RAM 3 through the OR gate 5, the input data from a data input terminal 107 is written in the RAM 3 through the selector 2, and at that time, an address is inputted from a WRITE address input terminal 103 and is impressed to the RAM 3 through the selector 1. When it goes to the period of a READ pulse (B), the selector 1 selects a signal from a READ address input terminal 104, and the selector 2 selects the '0' side of the data. The data from the RAM 3 is read out by a latch pulse (c), and appears at a data output terminal 108, and the data 0 is written in the RAM 3 by a refresh pulse (d). Thus, an output waveform to correspond to the number of the times of the inputs is obtained.
