Abstract: A digital camera has a detachable recording medium of either a first type into and from which data can be written and erased a plurality of times or a second type into which data can be written only once. A recording switch arrangement has a first-stage switch and a second-stage switch. In cases where the recording medium is of the first type, still-picture data are written into the recording medium when the first-stage switch is actuated. In cases where the recording medium is of the second type, data representative of a still picture are captured and the still picture represented by the captured data is indicated as a preview picture when the first-stage switch is actuated. Then, the captured data are written into the recording medium provided that the second-stage switch is actuated while the first-stage switch remains actuated.
