Abstract

An example eye fundus imaging apparatus can include: a display device; an image capture device configured to capture at least one image of a fundus of an eye; and a control module programmed to: display a target, the target indicating a desired position for the image capture device to capture the at least one image of the fundus of the eye; monitor a relative position of the eye with respect to the target; and when the relative position of the eye corresponds to the target, automatically capture the at least one image of the fundus of the eye.

Claims (27)

1. An eye fundus imaging apparatus, comprising:

a display device;

an image capture device configured to capture at least one image of a fundus of an eye; and

a control module that:

displays a target, the target indicating a desired position for the image capture device to capture the at least one image of the fundus of the eye;

determines a delta vector between the eye and the image capture device, the delta vector corresponding to a difference in position between a current location of a pupil of the eye and a desired location of the pupil; and

moves the target, based upon the delta vector, to position the eye relative to the image capture device to allow for capture of the at least one image of the fundus of the eye.

2. The eye fundus imaging apparatus of claim 1 , wherein the eye fundus imaging apparatus is a handheld apparatus.

3. The eye fundus imaging apparatus of claim 1 , wherein the control module further displays the target for the pupil of the eye.

4. The eye fundus imaging apparatus of claim 1 , wherein the target is a cursor.

5. The eye fundus imaging apparatus of claim 1 , wherein the eye fundus imaging apparatus is a wearable apparatus.

6. The eye fundus imaging apparatus of claim 5 , wherein the wearable apparatus includes a display device to show the target.

7. The eye fundus imaging apparatus of claim 6 , wherein the display device includes a projector that projects the target.

8. The eye fundus imaging apparatus of claim 1 , wherein the control module continues to calculate the delta vector to position the eye relative to the image capture device.

9. The eye fundus imaging apparatus of claim 8 , wherein the control module continues to reposition the target to position the eye relative to the image capture device.

10. A method for eye fundus imaging, comprising:

displaying a target, the target indicating a desired position for the image capture device to capture the at least one image of the fundus of the eye;

determining a delta vector between the eye and the image capture device, wherein the delta vector corresponds to a difference in position between a current location of a pupil of the eye and a desired location of the pupil for fundus imaging; and

moving the target, based upon the delta vector, to position the eye relative to the image capture device to allow for capture of the at least one image of the fundus of the eye.

11. The method of claim 10 , wherein the eye fundus imaging apparatus is a handheld apparatus.

12. The method of claim 10 , further comprising displaying the target for the pupil of the eye.

13. The method of claim 10 , wherein the target is a cursor.

14. The method of claim 10 , wherein the eye fundus imaging apparatus is a wearable apparatus.

15. The method of claim 14 , wherein the wearable apparatus includes a display device to show the target.

16. The method of claim 15 , wherein the display device includes a projector that projects the target.

17. The method of claim 10 , further comprising continuing to calculate the delta vector to position the eye relative to the image capture device.

18. The method of claim 17 , further comprising continuing to reposition the target to position the eye relative to the image capture device.
