1. An apparatus comprising:
- a display;
a camera; and
processing logic in communication with the display and the camera, the processing logic configured to;
receive image data associated with the camera;
determine a degree to which the camera is in focus based on the image data;
blur a visible base image having content that is independent of content in the image data from the camera to generate a proxy image that has a same degree of blurring across an entirety of the proxy image that inversely correlates with the degree to which the camera is in focus;
display the proxy image on the display; and
instruct a user to adjust a camera focus mechanism to better focus the proxy image,wherein the processing logic receives updated image data associated with the camera after displaying the proxy image, determines a new degree to which the camera is in focus, modifies the degree of blurring of the proxy image to inversely correlate with new degree to which the camera is in focus, and displays an updated proxy image based on the modified degree of blurring.

Abstract
A system and method for focusing a camera is disclosed. The system may generate a proxy image that is blurred to an extent that is correlated to a degree to which a camera is out of focus. A user may be asked to adjust a focusing mechanism to attempt to bring the proxy image into focus. This allows the camera to be focused without the user needing to see an image from the camera. This can be used, for example, to focus an infrared camera. The infrared camera could be a tracking camera in a device such as a head mounted display device.

10. A method comprising:
-
receiving image data associated with a camera; determining a degree to which the camera is in focus based on the received image data; accessing a visible base image from processor readable storage, wherein the visible base image has content that does not match content in an image from the camera; blurring the visible base image to generate a proxy image that has a same degree of blurring across an entirety of the proxy image that inversely correlates with the degree to which the camera is in focus; displaying the proxy image on a display; instructing a user to adjust a focus mechanism that is configured to focus the camera to bring the proxy image into better focus; repeating said receiving, determining, blurring, and displaying until the camera is focused to an adequate degree, including receiving updated image data associated with the camera, determining a new degree to which the camera is in focus, modifying the degree of blurring of the proxy image to inversely correlate with the new degree to which the camera is in focus, and displaying the modified proxy image on the display. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A head mounted display (HMD), comprising:
-
a near-eye, see-through display; an infrared (IR) camera; processor readable storage; an IR camera focus mechanism configured to focus the IR camera; and a processor in communication with the infrared camera and the near-eye, see-through display, the processor configured to; receive an infrared image from the IR camera; determine a degree to which the infrared image is out of focus; access a visible base image from the processor readable storage, wherein the visible base image is an image other than an image from the IR camera and has content that does not match content in the image from the IR camera; blur the visible base image to create a proxy image that has a same degree of blurring across an entirety of the proxy image that correlates with the degree to which the infrared image is out of focus; display the blurred proxy image on the near-eye, see-through display; and determine whether the IR camera is adequately focused responsive to a change in the IR camera focus mechanism after the blurred proxy image is displayed, wherein the processor is further configured to receive updated image data associated with the IR camera after displaying the proxy image, determine a new degree to which the IR camera is in focus, modify the degree of blurring of the proxy image to inversely correlate with new degree to which the IR camera is in focus, and display an updated proxy image based on the modified degree of blurring. - View Dependent Claims (18, 19, 20)
