In a digital camera, in an automatic shooting stand-by state, when it is judged that an automatic shooting condition has not been satisfied, it is judged whether or not to issue an AE re-processing command (that is, it is judged whether or not the current shooting condition is similar to a condition where the automatic shooting condition is satisfied). When it is judged to issue the AE re-processing command, exposure tracking in an aperture-priority mode is performed, and shooting exposure conditions excluding the aperture value for still-image shooting in the aperture-priority mode are determined. Then, storage is updated. When it is judged that an automatic shooting condition has been satisfied, record processing for still-image shooting is performed with the updated shooting exposure conditions without changing the aperture value.
