Abstract

A method and system for managing a removable memory used in a digital camera. The method and system includes creating a camera folder on the removable memory corresponding to the digital camera when the removable memory is first inserted into the digital camera. When images are captured, the images are stored only in the folder, such that the removable memory can be used with more than one digital camera without image name conflicts.

Claims

1. A method for managing a removable memory used in a digital camera, comprising the steps of:

(a) in response to the removable memory being inserted into a first digital camera, automatically creating a camera folder on the removable memory that uniquely identifies the first digital camera;

(b) storing images captured by the first digital camera in the camera folder;

(c) in response to the removable memory being transferred from the first digital camera to a second digital camera, automatically creating a second camera folder on the removable memory that uniquely identifies the second digital camera; and

(e) storing images captured by the second digital camera in the second camera folder, such that image name conflicts between the first and second digital cameras are avoided.

2. A method as in claim 1 wherein the digital camera includes an assigned serial number, step (a) further including the steps of:

(a1) generating a folder name using the serial number; and

(a2) assigning the folder name to the camera folder.

3. A method as in claim 2 wherein step (a1) further includes the steps of:

(a1)(i) providing the folder name with a serial number field; and

(a1)(ii) using the serial number field to represent the serial number assigned to the digital camera.

4. A method as in claim 3 wherein step (a1) further including the steps of:

(a1)(iii) providing the folder name with a prefix to identify what type of device the folder corresponds to.

5. A digital camera comprising:

a non-volatile memory for storing a serial number assigned to the digital camera;

a memory device removably inserted in the digital camera for storing sets of image data, each of the sets of image data corresponding to a captured image; and

a processor coupled to the non-volatile memory and to the memory device for controlling operation of the digital camera, the processor functioning to automatically generate a first folder on the memory device when the memory device is first inserted into the digital camera, and for generating a unique folder name for the first folder using the serial number, wherein images captured by the digital camera are stored in the memory device only in the first folder; and

in response to the removable memory being transferred from the first digital camera to a second digital camera, automatically creating a second camera folder on the removable memory that uniquely identifies the second digital camera.

6. A digital camera as in claim 5 wherein the folder name includes a serial number field for displaying the serial number.

7. A digital camera as in claim 6 wherein the folder name includes a prefix that identifies what type of device the first folder corresponds to.

8. A digital camera as in claim 7 wherein the digital camera further includes a user interface, the processor further functioning to scan to the memory device and to display in the user interface any folders and image data found in the memory device.

9. A digital camera as in claim 8 wherein the processor removes references to the folders and image data found in the digital camera when the memory device is removed from the digital camera.

10. A method for managing a removable memory in a digital such that the removable memory may be used with more than one digital camera without image name conflicts, the method comprising the step of:

(a) inserting the removable memory into the digital camera;

(b) scanning the removable memory and inventorying any folders and images found on the removable memory;

(c) generating a unique folder name that uniquely identifies the digital camera;

(d) attempting to create a first folder having the unique folder name on the removable memory for the digital camera;

(e) generating an error condition in response to the first folder being found on the removable memory;

(f) creating the first folder on the removable memory in response to the first folder not being found on the removable memory; and

(g) in response to a user capturing an image, storing the image on the removable memory only in the first folder; and

(h) in response to the removable memory being transferred from the first digital camera to a second digital camera, automatically creating a second camera folder on the removable memory that uniquely identifies the second digital camera.

11. A method as in claim 10 wherein step (c) further includes the step of:

(c1) generating the folder name using a serial number assigned to the digital camera.

12. A method as in claim 11 wherein step (b) further includes the step of:

(b1) displaying any folders and images found in the removable memory in a view finder on the digital camera.

13. A method as in claim 12 wherein step (b) further includes the step of:

(b2) in response to the user ejecting the removable memory, deleting any reference, to the folders and images found on the removable memory.
