Abstract
A digital camera of a digital camera system includes an image capture unit and a storing unit for storing the captured image in a memory. A computer of the system issues a capture command for capturing an image by the digital camera or a delete command for deleting the image stored in the memory. The digital camera generates an event signal indicating a change in stored content in the memory by a common sequence when stored content is changed in response to the capture or delete commands and when the stored content is changed in response to a digital camera operation. The computer issues a control command for collecting the stored content by a common sequence in response to the event signal when the stored content is changed in response to the capture or delete commands and when the stored content is changed in response to a digital camera operation.
