Abstract

A digital camera includes a capability for recovering memory by converting an existing digital photograph to a lower quality setting so that the photograph consumes less memory. The camera'"'"'s user interface associates the conversion capability with the deletion of photographs. The original higher quality photograph may optionally be automatically deleted as part of the conversion process.

Claims

1. A digital camera comprising:

a) storage that holds digital photographs;

b) logic that processes digital photographs; and

c) a user interface by which a user directs the logic to carry out operations, the user interface associating operation choices for deleting a digital photograph from the storage and for re-compressing a digital photograph.

2. The digital camera of claim 1 wherein an original photograph from which a re-compressed photograph is made is deleted from storage when the operation choice for re-compression is selected.

3. The digital camera of claim 1 wherein an original photograph from which a re-compressed photograph is made is kept in storage when the operation choice for re-compression is selected.

4. The digital camera of claim 1 further comprising an operation choice in the user interface comprising two settings such that:

a) when the user selects the first setting, an original photograph from which a re-compressed photograph is made is deleted from storage; and

b) when the user selects the second setting, an original photograph from which a re-compressed photograph is made is kept in storage.

5. The digital camera of claim 1 further comprising multiple quality levels at which photographs may be stored, and wherein the operation choice for re-compressing a photograph is indicated to be inactive when a photograph is already stored at the lowest quality setting.

6. A digital camera user interface wherein a choice by which a user directs the camera to delete a photograph is associated with a choice by which a user directs the camera to re-compress a photograph.

7. The digital camera user interface of claim 6 wherein the choice by which a user directs the camera to re-compress a photograph is indicated to be inactive when a photograph is stored at a lowest available quality level.

8. The digital camera user interface of claim 6 further comprising a second level with two choices such that:

a) when a user selects the first choice, an original photograph from which a re-compressed photograph is made is deleted; and

b) when a user selects the second choice, an original photograph from which a re-compressed photograph is made is kept.

9. The digital camera user interface of claim 6 comprising a choice by which a user directs the camera to re-compress all photographs contained in the camera.

10. A digital camera comprising:

a) logic means for deleting and re-compressing photographs;

b) user interface means by which the camera receives direction from a user, the user interface means associating operation choices by which the user directs the logic to delete a photograph and by which the user directs the logic to re-compress a photograph.

11. The camera of claim 10 wherein a photograph from which a re-compressed photograph is made is deleted.

12. The camera of claim 10 wherein a photograph from which a re-compressed photograph is made is not deleted.

13. The camera of claim 10 wherein the user interface means allows the user to specify whether to delete a photograph from which a re-compressed photograph is made.

14. The camera of claim 10 wherein the user interface means allows the user to direct the camera to re-compress all photographs contained in the camera.

15. A method of interacting with a user of a digital camera comprising the steps of:

a) presenting a selection of operation choices including choices for deleting and re-compressing an original image;

b) detecting the actuation of a user control directing the camera to re-compress the original image; and

c) re-compressing the original image, creating a re-compressed image from the original image.

16. The method of claim 15 further comprising the step of deleting the original image.

17. The method of claim 15 further comprising the step of presenting a second selection of operation choices including a choice indicating that the original image is to be deleted after re-compression, and a choice indicating that the original image is to be preserved.

18. The method of claim 15 wherein the operating choice for re-compressing an image is presented as inactive when the image is already stored at a lowest available quality setting.

19. The method of claim 15 further comprising the step of presenting an operation choice that allows the user to direct the camera to re-compress all of the images contained in the camera.
