To surely detect an operating state on a touch panel and surely execute a desired operation according to the operation.
A digital camera having the reproducing unit comprises a touch panel detecting circuit 19 determining an orthogonal coordinate system on the touch panel 7 and outputting, upon detecting an operating position on the touch panel 7, position data of the operating position by the orthogonal coordinate system; and a system controller 12 or the like for displaying content data and an operation support mark showing an operating area on a liquid crystal monitor 18, performing, in a case that the position data from the touch panel detecting circuit 19 are present in an area shown by the operation support mark, coordinate conversion according to the shape of the operation support mark to the position data, calculating an operation quantity from the converted position data, and selectively displaying content data from storage media 13 according to the operation quantity.
