In a digital camera, when a shutter button is depressed into its half stroke, a subject is photographed as a preparatory image, in which the face of a person is identified as a face area. Such a face area at the latest time is compared with a corresponding face area in another preparatory image taken immediately preceding to the latest time. If no substantial difference exists between both, the face area is determined as a stationary object and excluded from a set of identified face areas, of which the remaining ones are adopted as the face areas selected, based on which, optimum exposure and focusing values are calculated. When the shutter button is depressed into its full stroke, the calculated optimum exposure is carried out with the optimum focusing value to photograph a subject as a live image. The face area of the subject is freely selectable.
