Abstract

In cameras and methods, a series of archival images are captured in a film unit in the camera. A series of electronic images corresponding to the archival images are captured in the camera. The electronic images are stored in memory of the camera. Unloading of the film unit from the camera is detected. Responsive to the unloading, selective clearance of the electronic images in memory is enabled.

Claims

1. A method for managing electronic images in a camera, said method comprising the steps of:

capturing a series of archival images in a film unit in the camera;

capturing a series of electronic images corresponding to said archival images;

storing said electronic images in memory of said camera;

detecting unloading of said film unit from said camera; and

responsive to said unloading, enabling selective clearance of said electronic images in said memory.

2. The method of claim 1 further comprising signaling the availability of said clearance of said electronic images.

3. The method of claim 1 further comprising enabling clearance of metadata corresponding to said electronic images with said clearance of said electronic images.

4. The method of claim 1 further comprising retaining selected said electronic images following said enabling, loading another film unit and overwriting said selected electronic images following said loading.

5. The method of claim 1 further comprising, following said enabling, clearing one or more of said electronic images and retaining, in said memory, one or more others of said electronic images.

6. The method of claim 1 further comprising disabling clearance of said electronic images in said memory prior to said detecting of said unloading.

7. The method of claim 1 further comprising accepting user input identifying selected ones of said electronic images.

8. The method of claim 7 further comprising, following said accepting, clearing said selected ones of said electronic images.

9. The method of claim 8 wherein said clearing produces an empty space in said memory and said method further comprises assigning said empty space to the head of an overwriting queue.

10. The method of claim 9 further comprising, following said clearing, loading another film unit, and following said assigning, capturing one or more additional electronic images and storing said one or more additional electronic images in said empty space.

11. The method of claim 10 further comprising retaining, in said memory, one or more others of said electronic images of said series during said clearing and assigning.

12. The method of claim 11 further comprising sequentially overwriting said one or more others of said electronic images of said series following said storing of one or more additional electronic images in said empty space.

13. A method for managing electronic images in a camera, said method comprising the steps of:

capturing a series of archival images in a film unit in the camera;

capturing a series of electronic images corresponding to said archival images;

storing said electronic images in memory of said camera;

detecting unloading of said film unit from said camera;

responsive to said unloading, enabling selective clearance of said electronic images in said memory; and

disabling clearance of said electronic images in said memory prior to said detecting of said unloading.

14. A hybrid electronic-film camera for use with a photographic film unit, said camera comprising:

a body having a film space holding the film unit;

a signaler disposed in operative relation to said film space, said signaler generating a removal signal responsive to removal of said film unit;

a capture system disposed in said body, said capture system being selectively actuable to capture a series of light images as image pairs, each said image pair having an archival image and an electronic image of the same light image, said capture system having an archival image capture unit capturing said archival images in the film unit in a first aspect ratio, said capture system having an electronic capture unit capturing said electronic images;

memory disposed in said body, said memory being operatively connected to said electronic capture unit, said memory storing said electronic images, said memory having a predetermined storage capacity, said memory filling with said electronic images to said storage capacity and then sequentially replacing a plurality of said electronic images in said memory on a first in-first out basis; and

a controller operatively connected to said signaler and said memory, said controller allowing selective clearing of said electronic images from said memory responsive to said removal signal.

15. The camera of claim 14 further comprising one or more displays mounted to said camera, said displays communicating user instructions following said clearing signal.

16. The camera of claim 14 further comprising a plurality of user controls disposed on said body, said user controls being operatively connected to said controller, said user controls being selectively actuable to designate selected ones of said electronic images for said clearing.

17. The camera of claim 16 further comprising an image display mounted on said body, said image display showing said electronic images.

18. A hybrid electronic-film camera for use with a photographic film unit, said camera comprising:

a body having a film holder removably holding the film unit;

a signaler disposed in operative relation to said film holder, said signaler being switchable between a first state and a second state, said signaler being in said first state when said film unit is in said film holder and in said second state when said film holder is free of said film unit;

a capture system disposed in said body, said capture system being selectively actuable to capture a series of light images as image pairs, each said image pair having a latent film image and electronic image of the same light image, said capture system having a film capture unit capturing said latent images on the photographic film in a first aspect ratio, said capture system having an electronic capture unit capturing said electronic images;

memory disposed in said body, said memory being operatively connected to said electronic capture unit, said memory having a predetermined storage capacity, said memory filling with said electronic images to said storage capacity and then sequentially replacing a plurality of said electronic images in said memory on a first in-first out basis; and

a controller operatively connected to said signaler and said memory, said controller blocking selective clearing of said electronic images when said signaler is in said first state, said controller allowing selective clearing of said electronic images when said signaler is in said second state.

19. The camera of claim 18 further comprising a plurality of user controls disposed on said body, said user controls being operatively connected to said controller, said user controls being selectively actuable to designate selected ones of said electronic images for said clearing.

20. The camera of claim 19 further comprising an image display mounted on said body, said image display selectively showing said electronic images.

21. A method for managing electronic images in a camera, said method comprising the steps of:

capturing a series of archival images in a film unit in the camera;

capturing a series of electronic images corresponding to said archival images;

storing said electronic images in memory of said camera;

detecting unloading of said film unit from said camera; and

responsive to said unloading, enabling editing of said electronic images in said memory.
