Abstract

PROBLEM TO BE SOLVED: To provide a camera with a monitor which does not allow irregularities to be produced in an image on an electronic finder, when a mirror is set up and prevents the unsightliness. SOLUTION: Whether a 1st release is turned on is decided (S5). When it is on, photometry, range-finding an focus driving before photographing are performed (S80 to S90). Meanwhile, when it is turned off, image-pickup operation is permitted (S10) and monitor display is permitted (S15). Whether a 2nd release is turned on is decided (S20). When it is turned on, whether the 1st release is turned on is decided (S25). When it is turned on, whether a subject is already focused is decided (S30). When it is not been focused yet, the operation advances to S10 after performing steps S80 to S90. Meanwhile, when the 2nd release is turned on at the step S20, the monitor display is 'fixed' (S35). Continuingly, the mirror is set up, diaphragm control and shutter control are performed, and a mirror is set down (S50). A film is wound by one frame (S60), and whether power SW is turned on is decided (S70). When it is turned on, the operation returns to the step S5. When the power SW is turned off, a series of steps is finished.
