Title: Optical picture input device
Inventor: TAKENAKA SHINYA
IPC: G06T1/00
Filed: 1987-07-10
Abstract: PURPOSE:To select a constantly proper binarization condition irrespective of a printing state by comparing the level of a picture signal with a prescribed slice level and deciding the slice level based on the result. CONSTITUTION:A comparator 1 compares a picture signal P with the prescribed slice level A and when the picture signal P is higher than the level A, a high level control signal CH is outputted and when it is low, a low level control signal CL is outputted. A delay circuit 2 delays the picture signal P to form a time allowance until and A/D converting circuit 3 normally operates. Then, the A/D converting circuit 3 raises the slice level B at the time of inputting the signal CH from a comparator 1 and on the contrary, at the time of inputting the signal CL, it lowers the slice level B. The slice level B can be fixed to change the level of the picture signal P.

Title: Voltage control type oscillating circuit
Inventor: SHIMANO OSAMU
IPC: H04N9/45
Filed: 1982-10-06
Abstract: PURPOSE:To always obtain a desired phase shift degree despite a phase shift circuit incorporated into an IC by producing the pulse signal having a prescribed phase difference to the oscillation signal from a D-FF circuit. CONSTITUTION:The transmission signal led to a terminal P1 is squared by a squaring circuit 21, undergoes the waveform shaping to be changed to a pulse signal S3 of 50% duty through a waveform shaping circuit 22 and supplied to a D-FF circuit 23 in the form of a clock pulse. While the oscillation signal led to the terminal P1 undergoes the waveform shaping to be changed to a pulse signal S4 of 50% duty through a waveform shaping circuit 24 and is supplied to the circuit 23 in the form of a D input. In such a constitution, the fall phase of the signal S3 has a 45 shift compared with the fall phase of the signal S4. Here the circuit 23 is set so that the signal S4 is read in the fall timing of the signal S3. Therefore a Q output signal S5 has a phase delayed by 45 compared with the signal S4. As a result, the variance of phase shift degree is reduced, and no problem is produced although an oscillated signal is converted into an IC.
