A digital camera of the present invention includes a receiving portionthat receives a control signal from a remote controller, and a microcomputerhaving a live view mode controlling so that image data generated by a CMOS sensoror image data obtained by subjecting the image data generated by the CMOS sensorto predetermined processing is displayed on a liquid crystal monitoras a moving image in real time, wherein when the receiving portionreceives the control signal from the remote controller, the microcomputercontrols so as to shift the digital camera to a live view mode. Due to this configuration, in a digital camera that includes a movable mirror and is capable of displaying a subject image in a live view through an electronic viewfinder, the operability thereof can be enhanced.

Digital camera

An objective lens element which has excellent compatibility with optical discs having different base material thicknesses is provided. An objective lens elementhas optically functional surfaces on an incident side and an exit side. Either one of the optically functional surfaces is divided into an inner partB including a rotational symmetry axis and an outer partF which is a ring-shaped region surrounding the inner partB. On the inner partB, a plurality of discontinuous steps are provided. The plurality of steps change in height in the same direction from the optical axis toward the outer part, and each of the steps causes a constant optical path difference longer than the wavelength &#x3bb;to the first incident light beamand causes a constant optical path difference shorter than the wavelength &#x3bb;to the second incident light beam

A digital camera of the present invention includes a microcomputerhaving a live view mode controlling so that image data generated by a CMOS sensoror image data obtained by subjecting the image data generated by the CMOS sensorto predetermined processing is displayed on a liquid crystal monitoras a moving image in real time, wherein when a release buttonreceives an instruction regarding start of an autofocus operation in a live view mode, the microcomputercontrols a movable mirror to enter an optical path to measure by an AF sensor, and thereafter, allow the movable mirror to retract from the optical path to return the digital camera to the live view mode. Due to this configuration, in a digital camera that includes a movable mirror and is capable of displaying a subject image in a live view through an electronic viewfinder, the operability thereof can be enhanced.

Digital camera with movable mirror for AF in live view mode and optical viewfinder mode

Provided is an imaging device capable of accurately and rapidly selecting a main image from a plurality of continuously captured images and simplifying handling of image files recorded on a memory card. With one operation, it is possible to capture a plurality of continuous images at a predetermined time interval. A main image is selected from the captured images and the image data on the main image and the image data on sub images other than the main image are recorded as one image file on a recording medium ().

Imaging device

The camera system is constituted by the camera main body and the interchangeable lens, which is removably attachable to the camera main body. The camera main body has an imaging unit, a main body shake detector, a main body image blur corrector, and a body microcomputer configured to control the imaging unit, the shake detector, and the image blur corrector. The interchangeable lens has a shake detector, an image blur corrector, and a lens microcomputer configured to control the shake detector and the image blur corrector. The body microcomputer selects either the main body or lens shake detector, activates the selected shake detector, and stops the other shake detector.
