System and method for accessing data of a digital camera from a personal computer
First Claim
1. A digital photographic system comprising:
- (a) a digital camera having memory for storing digital images captured by the camera;
(b) a personal computer having an operating system and a communication port;
(c) means, disposed in said personal computer, for accessing the memory in the digital camera through the communication port to make the memory appear as a disk to the operating system;
said accessing means including a dynamic file directory for accessing and retrieving a file size from the memory, and a virtual file allocation table for indicating virtual captured image location computed from the file size retrieved by the dynamic file directory for creating the appearance of a file allocation table, which stores a location of recorded datum for ultimately permitting said operating system to access the captured images, wherein the virtual file allocation table includes correlating captured image location to a captured image by adding each file size corresponding to a captured image that precedes a desired image to be retrieved for determining the captured image location.

Abstract
A digital photographic system comprises a digital camera having memory for storing digital images recorded by the camera and a personal computer having a disk operating system and a serial communication port. A software program permits the computer to access the memory in the digital camera through the serial communication port to make the memory appear as a disk to the operating system. The program includes a dynamic file directory for accessing and retrieving a file size from the memory, and a virtual file allocation table for indicating virtual captured image location in the memory computed from the file size retrieved by the dynamic file directory for creating the appearance of a file allocation table, which stores a location of captured datum for ultimately permitting said operating system to access the captured images.

6. A method for accessing data of a digital camera from a personal computer having a disk operating system and a communication port, the method comprising the steps of comprising:
-
(a) accessing memory in the digital camera through the communication port of the personal computer to make the memory appear as a disk to the operating system; (b) creating a dynamic file directory for accessing and retrieving a file size from the memory of the digital camera; (c) providing a virtual file allocation table for indicating a virtual captured image location in the memory computed from the file size retrieved by the dynamic file directory for creating the appearance of a file allocation table, which stores a location of stored datum for ultimately permitting the operating system to access the captured images; and (d) correlating virtual disk image file location to a correct captured image in the camera by matching location information provided by the virtual disk with entries in the dynamic file directory so that the desired image is retrieved. - View Dependent Claims (7, 8)
