Abstract: An automatic focus control method and apparatus are capable of correctly controlling the focus even when an object having a high contrast enters or leaves goes out from a distance measurement frame during the focusing operation. A control microcomputer monitors the detecting position of the focusing signal generated by an automatic focus detection circuit. If the control microcomputer concludes that the detecting position of the focusing signal is in a peripheral area of the distance measurement frame, the control microcomputer outputs a distance measurement frame control signal to change the location or the size of the distance measurement frame so that an object having a high contrast no longer either enters or goes out from the distance measurement frame.

Abstract: An image which is seen as a natural feeling can be attained in such a manner that a resolution of a photographed image is kept substantially constant irrespective of any variation in condition of an optical system such as an iris diaphragm diameter and a zoom position. For example, in the case that it is adapted for an iris diaphragm diameter, an MTF corresponding to a variation of an iris diaphragm diameter is measured (FIG. 6A) and then a gain of an output of an aperture control circuit capable of canceling a reduction of high frequency component of the image signal corresponding to the measured MTF (FIG. 6B). Then, an iris diaphragm diameter varied during a photographing operation is detected, a gain set in response to the detected iris diaphragm diameter is applied to the aperture control circuit, thereby a control is carried out such that an amplitude of the high frequency component of the brightness signal (FIG. 6C) being kept substantially constant without having any relation with the iris diaphragm.

Abstract: An electrical power efficiency of the driving circuit is improved. The OP amplifier in the control arithmetic circuit compares a controlling amount with an added value of a target value and an AC signal and then outputs the comparing signal to the driving circuit. Since the transistor in the driving circuit is controlled in switching by the comparing signal, its loss of electrical power is reduced. Accordingly, an electrical power efficiency of the driving circuit is improved. In addition, the driving circuit drives the actuator section, a controlling amount of the actuator is detected by the position sensing unit and it is fed back as the controlling amount to the controlling arithmetic circuit.
