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 guiding a subject image to an optical viewfinder, comprising: an image pickup element that captures the subject image formed by the image pickup optical system to generate image data; a display element 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 photometric element that measures an amount of light from a subject when the movable mirror is positioned in the optical path of the image pickup optical system; an illumination element that illuminates the subject with light; and a control element 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 element as a moving image in real time, characterised in that, when the digital camera is being operated in a live view mode, in a case of measuring the amount of light from the subject without allowing the illumination element to flash light, the control element controls so that the amount of light is obtained based on the image data generated by the image pickup element, while in a case of measuring the amount of light from the subject by allowing the illumination element to flash light, the control element controls so that the movable mirror enters the optical path of the image pickup optical system, the illumination element flashes light, and measurement results of the photometric element are obtained. an image pickup element that captures the subject image formed by the image pickup optical system to generate image data; a display element 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 photometric element that measures an amount of light from a subject when the movable mirror is positioned in the optical path of the image pickup optical system; an illumination element that illuminates the subject with light; and a control element 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 element as a moving image in real time, characterised in that, when the digital camera is being operated in a live view mode, in a case of measuring the amount of light from the subject without allowing the illumination element to flash light, the control element controls so that the amount of light is obtained based on the image data generated by the image pickup element, while in a case of measuring the amount of light from the subject by allowing the illumination element to flash light, the control element controls so that the movable mirror enters the optical path of the image pickup optical system, the illumination element flashes light, and measurement results of the photometric element are obtained.
