Digital camera

1. A digital camera having a movable mirror provided so as to enter or retract with respect to an optical path of an image pickup optical system for purpose of guiding a subject image to an optical viewfinder or a display, comprising:

an image pickup element that captures the subject image formed by the image pickup optical system to generate image data;

a display portion that displays the image data generated by the image pickup element or image data obtained by subjecting the image data generated by the image pickup element to predetermined processing;

a receiving portion that receives control signals from a remote controller in response to manipulations of the remote controller by a user; and

a control portion having a live view mode controlling so that the image data generated by the image pickup element or the image data obtained by subjecting the image data generated by the image pickup element to predetermined processing is displayed on the display portion as a moving image in real time,

wherein in response to the receiving portion receiving any control signal from the remote controller, the control portion controls so as to shift the digital camera to a live view mode and retract the movable mirror from the optical path of the image pickup optical system.

2. A digital camera having a movable mirror provided so as to enter or retract with respect to an optical path of an image pickup optical system for purpose of guiding a subject image to an optical viewfinder or a display, comprising:

an image pickup element that captures the subject image formed by the image pickup optical system to generate image data;

a display portion that displays the image data generated by the image pickup element or image data obtained by subjecting the image data generated by the image pickup element to predetermined processing;

a tripod fixing portion for fixing the digital camera to a tripod;

a contact detector for detecting that the digital camera to a tripod by the tripod fixing portion; and

a control portion having a live view mode controlling so that the image data generated by the image pickup element or the image data obtained by subjecting the image data generated by the image pickup element to predetermined processing is displayed on the display portion as a moving image in real time,

wherein in response to the contact detector detecting that the digital camera is fixed to the tripod by the tripod fixing portion, the control portion controls so as to shift the digital camera to a live view mode and retract the movable mirror from the optical path of the image pickup optical system.

3. The digital camera according to claim 2 , further comprising:

a distance-measuring portion that receives the subject image and obtains information on a distance from the subject to the digital camera in a state where the movable mirror enters the optical path; and

an autofocus portion that adjusts a focus of the subject image by adjusting the image pickup optical system in accordance with measurement results of the distance-measuring portion, wherein when the digital camera is fixed to the tripod by the tripod fixing portion, the control portion controls the autofocus portion first so that an autofocus operation is performed immediately after the digital camera is fixed to the tripod or after a predetermined time elapses from the time when the digital camera is fixed to the tripod, and thereafter, the control portion controls so that the digital camera is shifted to the live view mode.

4. The digital camera according to claim 3 , further comprising a setting portion that sets the control portion in the live view mode,

wherein when the digital camera is fixed to the tripod by the tripod fixing portion, the control portion controls so as to shift the digital camera to the live view mode after controlling the autofocus portion first so that the autofocus operation is performed, in accordance with setting of the live view mode by the setting portion.

5. The digital camera according to claim 2 , further comprising an autofocus portion that adjusts a focus of the subject image by adjusting the image pickup optical system, using contrast of the image data generated by the image pickup element or image data obtained by subjecting the image data generated by the image pickup element to predetermined processing,

wherein when the digital camera is fixed to the tripod by the tripod fixing portion, the control portion controls the autofocus portion so that the autofocus operation is operated immediately after the digital camera is fixed to the tripod by the tripod fixing portion or after a predetermined time elapses from the time when the digital camera is fixed to the tripod.

6. The digital camera according to claim 5 , further comprising a setting portion that sets the control portion in the live view mode,

wherein when the digital camera is fixed to the tripod by the tripod fixing portion, the control portion controls so as to shift the digital camera to the live view mode and controls the autofocus portion so that the autofocus operation is performed, in accordance with setting of the live view mode by the setting portion.

7. The digital camera according to claim 1 , wherein after the digital camera has been shifted to the live view mode by the control portion and in response to a manipulation of the digital camera by the user, the control portion shifts the digital camera to an optical viewfinder mode and causes the moveable mirror to enter into the optical path of the image pickup optical system.

8. The digital camera according to claim 2 , wherein after the digital camera has been shifted to the live view mode by the control portion and in response to the contact detector detecting that the tripod has been detached from the tripod fixing portion of the digital camera, the control portion shifts the digital camera to an optical viewfinder mode and causes the moveable mirror to enter into the optical path of the image pickup optical system.
