Title: Color image pickup device
Inventor: TANAKA YOSHIKUNI
IPC: H04N9/04
Filed: 1982-04-14
Abstract: PURPOSE:To obtain a video signal of excellent picture quality, by separating the two output signals of a solid-state image pickup element and the 1H-delay output signal into four signals, limiting each maximum amplitude and obtaining red and blue color signals with a logical operation. CONSTITUTION:The output signal OH of a solid-state image pickup element 15 in which color filters are combined is delayed by a 1H delay line 16 by a time equivalent to a scanning line. The signal OH and a 1H-delayed signal 1H are applied to four gate circuits 17-20, and four signals are separated. In this case, a gate signal 21 is applied to the circuits 17 and 19, and a signal 22 having a 180 deg. phase difference to the signal 21 is applied to the circuits 18 and 20. Thus signals (a), (c), (b) and (d) are separated respectively. Then these signals are applied to limiters 23-26 with limitation given to each maximum amplitude. The output of this limitation is sent to arithmetic circuits 29 and 30. A blue signal is obtained from the circuit 29; while continuous red signals are obtained out of the output of the circuit 30 via an inverting circuit 31. Then a luminance signal Y is obtained from a gain control circuit 33.

Filed: 1995-02-24
Abstract: PURPOSE: To enhance the operational efficiency by detecting the rotor position accurately at all times regardless of the load in the control.method for brushiess motor. CONSTITUTION: A voltage induced in the armature winding of a brushless motor 3 is compared with a reference voltage at a position detecting section 4 and a rotor position detection signal is delivered to a control circuit 10. A switching element at an inverter section 4 is then turned ON/OFF to switch the armature winding current thus subjecting the switching element at an inverter section 3 to chopping control and performing rotation control and speed control. The control circuit 10 detects the ending timing of spike voltage occurring at the time of switching the armature winding current and calculates the Lime up to time cross point of the induced voltage and the reference voltage. Finally, the current switching timing of armature winding is determined at least based on the time thus calculated and the armature winding current of the brushless motor 3 is switched.
