Filed: 1988-01-22
Abstract: PURPOSE:To simplify an adjusting work by controlling the phase of the synchronizing signal or three primary color signal of a display circuit in correspondence to the phase difference of a three primary color signal output and setting the phase difference to a value which is determined in advance. CONSTITUTION:When a display position automatic adjustment start instruction is given to a display position control circuit 16, the display position control circuit 16 instructs a display circuit 11 to output R, G and B signals for picture display for display position adjustment. In a phase comparing circuit 15, phase comparison between a deflecting output pulse and R, G and B output pulses in a picture for display position adjustment is executed. In the display position control circuit 16, the delay part of the display circuit 11 is controlled in order to cause the phase difference from the circuit 15 to be a prescribed value. Thus, regardless of an influence such as the manufacture dispersion of a receiving device, the display picture can be always adjusted so as to be set to the center of a CRT automatically.

Title: Image reader
Inventor: KANEKO ATSUSHI
IPC: H04N1/04
Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of an image due to speed fluctuation of a scanning member, without the need for a special addition voltage and complicated image processing. SOLUTION: A motor 8 is driven as normal in the preliminary scanning first. A line sensor reads a speed fluctuation read pattern for a correction period before the speed of motor reaches a steady-state speed, and a control section 1 calculates speed fluctuation data, based on increment data of a pattern read width. Then the speed fluctuation of a motor 8 is generated intentionally, and a speed fluctuation read pattern and a speed fluctuation (gain) and a fluctuation delay (phase) of a carriage are acquired. When the motor is driven as normal in the main scanning, the motor speed is made to fluctuate intentionally to eliminate vibration of the carriage based on the speed fluctuation data, the speed fluctuation (gain) and the fluctuation delay (phase) of the carriage for the correction period.
