Claim:
An image pickup apparatus, comprising: an image pickup unit configured to capture a subject to obtain image data; an accessing unit configured to access an storage medium in which the image data is stored; a connecting unit configured to connect the image pickup unit to an information processing apparatus; a receiving unit configured to receive information about the information processing apparatus when the image pickup apparatus is connected to the information processing apparatus; a first storing unit configured to store the information received from the information processing apparatus; a generating unit configured to generate an identifier on the basis of a plurality of information, the plurality of information including information received from the information processing apparatus and count-up information which is updated every time an image is captured using the image pickup unit; a second storing unit configured to store the identifier therein so that the identifier is associated with the image data stored in the storage medium; and a determining unit configured to determine whether image data which is not associated with the identifier is stored in the storage medium, wherein when the determining unit determines that the image data which is not associated with the identifier is stored in the storage medium, the second storing unit associates the identifier generated using the generating unit with the image data and stores the image data therein, wherein the determining unit determines whether the image data which is associated with the identifier assigned by another apparatus is stored in the storage medium, and when it is determined that the image data which is associated with the identifier assigned by the another apparatus is stored in the storage medium, the generating unit generates a new identifier using the information received from the information processing apparatus and the count-up information.
