Title: Peak detecting circuit
Inventor: KINOSHITA OSAMU
IPC: G01R19/04
Filed: 1988-12-02
Abstract: PURPOSE:To reduce the generation of a peak detection error due to the change of a mark rate by equivalently decreasing the input bias currents of first and second amplifiers. CONSTITUTION:Since a switching transistor TR Q2 goes to an interrupted condition when an input signal is an H level, a charge accumulated in a capacitor 3 starts discharge. However, an input bias current Ib3 of a differential amplifier 1 and an input bias current Ib5 of a buffer amplifier 4 are equivalently decreased by a current Ib7 and discharging quantity is changed according to the size of the current Ib7. With this change, the potential of the capacitor 3 is changed. Here, by adjusting a resistor R10 so that the current Ib7 can be smaller than the sum of the currents Ib3 and Ib5, the potential of the capacitor 3 is prevented from being higher than the H level of the input signal. Thus, discharging loss is extremely reduced and the generation of the peak detection error due to the change of the mark rate can be reduced.

Abstract: PROBLEM TO BE SOLVED: To enable shift photographing improved in operability by including a resetting means for resetting the displacement of an imager to a reference position by driving a drive mechanism. SOLUTION: The optical system comprises a base block 1 containing a first mirror section 2 having a half mirror, an image pickup section 3 having the imager 32 which is an image pickup element, a finder optical system and a drive section 7 for causing the shift displacement of the image pickup section 3 and a visual frame section 4 of the finder optical system. Whether a shift mode changeover switch is set at a shift mode or not is checked. If the shift mode is not set, the reset operation of a shift state is executed. Namely, if the imager 32 exists in the shift position, the imager 32 is moved to the position where its photoelectric conversion plane center is aligned to an optical axis O without depending on the value of a shift volume. A shift mode flag F is thus reset at zoro.
