Abstract

An image capture system (100) having an image capture module (102) and a terminal unit (104) captures both photo images and coded images. An alterable optical path of the system (100) operates in a first configuration when capturing coded images and in a second configuration when capturing photo images. Captured images are presented on a display (114) as they are captured. A user of the system (100) may parse through captured images to select one or more of the captured images for permanent storage and/or transmission to a remote location. The system (100) operates to identify coded targets within captured images, to prompt the user to select one or more of the identified coded targets and to decode the selected coded targets. The image capture system (100) may direct a user to reposition the system (100) so that a decodable coded image will be captured. The image capture system (100) communicates over wireless and wired networks with remote computer systems (307), personnel, and mobile units (307).

Claims

1. An image capture system comprising:

an optical path;

a photo-detector that captures via the optical path images that comprise coded images and non-coded, photo images;

a controller, coupled to the photo-detector, selectively operable in a first mode and a second mode; and

the controller, when operating in the first mode, attempts to decode images captured by the photo-detector, and, when operating in the second mode stores captured images without attempting decoding.

2. The image capture system of claim 1, further comprising:

an illuminator unit operable in a first position to provide background lighting during capture of a non-coded, photo image and in a second position during capture of a coded image.

3. The image capture system of claim 1, further comprising image transfer interface circuitry connected to the controller.

4. The image capture system of claim 1, wherein the controller further comprises coded image decode circuitry.

5. The image capture system of claim 1, further comprising at least one image buffer.

6. The image capture system of claim 1, wherein the controller further comprises coded image quality determination circuitry.

7. The image capture system of claim 1 wherein the controller supports storage of pluralities of non-coded, photo images.

8. The image capture system of claim 7 further comprising a display that interacts with the controller to present the non-coded, photo images to a user of the image capture system.

9. The image capture system of claim 8 wherein the image capture system comprises a hand-held system.

10. An image capture system having a camera mode and a decode mode, the image capture system comprising:

an optics system that captures images;

an image buffer;

a processor that decodes images captured during the decode mode; and

the processor stores, without attempting to decode, images captured during the camera mode in the image buffer.

11. The image capture system of claim 10, further comprising:

an illuminator operable in a first position to provide background lighting when in the camera mode, and operable in a second position when in the decode mode.

12. The image capture system of claim 10 wherein the image buffer supports storage of pluralities of captured images.

13. The image capture system of claim 10 wherein images captured during the decode mode are treated as comprising coded images, while images captured during the camera mode are treated as comprising non-coded, photo images.

14. The image capture system of claim 13 wherein the non-coded, photo images comprise snapshot images.

15. The image capture system of claim 13 wherein the non-coded, photo images comprise frames captured at a rate acceptable for video reproduction.

16. The image capture system of claim 13 further comprising a display that interacts with the processor to present captured images to a user of the image capture system.

17. The image capture system of claim 16 wherein the image capture system comprises a hand-held system.

18. The image capture system of claim 17 used with a remote computing device wherein the image capture system communicates captured images to the remote computing device.

19. The image capture system of claim 17 wherein the image capture system comprises a terminal unit and an image capture module.

20. The image capture system of claim 10 wherein the optics system comprises an adaptive optical path.
