Abstract: An imaging device includes an imaging element, a shutter mechanism, an actuator, a rotatable transmission member, a position detector, and a drive controller. The shutter mechanism is switchable between an open and a closed state to control the light incident on the imaging element. The transmission member is configured to transmit a driving force produced by the actuator to the shutter mechanism. The position detector is configured to detect the rotational position of the transmission member. The drive controller is configured to direct the actuator to begin storing the driving force while image data is being read from the imaging element, to control the timing at which the actuator begins driving the shutter mechanism based on the position of the transmission member detected by the position detector, and to switch the shutter mechanism from the closed state to the open state after the actuator has stopped storing the driving force.

Abstract: An image capture device includes: an imager for imaging an object and generating image data; an image file generator for generating an image file by adding, to the image data generated by the imager, a header portion which stores at least one type of information concerning shooting circumstances; a timer for outputting information indicating a current time; and a manipulation section which is used to set period information specifying a period. The image file generator changes the type of information to be stored in the header portion depending on whether a time of imaging as indicated by the information which is output from the timer at the time of the imaging falls within the period specified by the period information.

The driving apparatus includes a control system for controlling the piezoelectric element in such a manner that a continuous supply of a certain number of drive pulses to the piezoelectric element and a non-supply thereof during a certain period of time are repeated by a “block pulse drive” at time of slow speed driving, and that the continuous supply thereof are continuously supplied to the piezoelectric element by a “continuous pulse drive” at time of high speed driving.

Abstract: In addition to a focus detecting sensor for phase difference detection, a camera is provided with a light source or a generator for emitting light or ultrasonic waves, and a light receiver or a receiver for receiving the light or the ultrasonic waves reflected from the object. The distance to the object is detected from the intensity of the reflected light or ultrasonic waves and the focusing lens is set at a position close to the in-focus position. Then, the driving range of the focusing lens is limited in accordance with the detected distance, and from the set focusing lens position, focusing by the phase difference detection method is performed within the limited driving range.
