An image acquisition architecture includes a device class representing a physical image acquisition device, a storage class representing storage areas of the image acquisition device, a package class representing sets of data files stored in a storage area of the image acquisition device, and an item class representing individual data files within the sets of data files stored in the storage area of the image acquisition device. |

DETAILED DESCRIPTION The present invention addresses the foregoing by providing an image acquisition architecture including a device class representing a physical image acquisition device, a storage class representing storage areas of the image acquisition device, a package class representing a set of data files stored in a storage area of the image acquisition device, and an item class representing individual data files within the set of data files stored in the storage area of the image acquisition device.
By virtue of the foregoing, the present invention allows simple manipulation of many types of image acquisition devices.
In particular, a digital camera can be represented by a device class, its internal memory card may be represented by a storage class, each "picture" in the memory card may be represented by a package class, and a full-resolution image, a thumbnail image file and a sound file corresponding to each "picture" may be represented as item classes within a single package.
Similarly, multiple storage devices in a digital video camera can each be represented as separate storage classes within a single device class.
As a result, manipulation and access of storages, packages and items within a device is greatly simplified.
In another aspect, the present invention concerns an application programming interface for use in interfacing with image acquisition devices, the interface including a function to access properties of a device class, the device class representing a physical image acquisition device, a function to access properties of a storage class, the storage class representing storage areas of the image acquisition device, a function to access properties of a package class, the package class representing sets of data files stored in a storage area of the image acquisition device, and a function to access properties of an item class, the item class representing individual data files within the sets of data files stored in the storage area of the image acquisition device
