## Abstract

A near-to-eye display device is provided that includes a camera for capturing images in a first field of view; at least one display positioned near to an eye of a person wearing the device for displaying images captured by the camera in a second field of view, wherein the second field of view is smaller than the first field of view; and a controller for selecting a portion of the images from the camera to display on the display. The controller being configured to automatically enter a reading mode upon detecting one of a downward tilt of the device and reading material within the images. In a reading mode, the controller selects a lower portion of the images to display on the display. When not in a non-reading mode, the controller selects a higher portion of the images to display on the at least one display.

## Claims

### Claim 1

A near-to-eye display device comprising:
a camera for capturing images in a first field of view;
at least one display positioned near to an eye of a person wearing the device for displaying images captured by the camera in a second field of view, wherein the second field of view is smaller than the first field of view; and
a controller in communication with the camera and the at least one display for selecting a portion of the images from the camera to display on the at least one display, the controller being configured to automatically enter a reading mode upon detecting one of a downward tilt of the device and reading material within the images captured by the camera, in a reading mode, the controller selects a lower portion of the images to display on the at least one display, and when in a non-reading mode, the controller selects a higher portion of the images to display on the at least one display.

### Claim 2 (depends on 1)

The near-to-eye display device of claim 1, wherein the controller selects a narrower field of view in the reading mode and a wider field of view in the non-reading mode.

### Claim 3 (depends on 1)

The near-to-eye display device of claim 1 and further including a sensor for sensing at least a downward tilt to which the controller responds by entering a reading mode.

### Claim 4 (depends on 3)

The near-to-eye display device of claim 3, wherein the sensor further senses pan and rotation of the device, wherein the controller responds to the detection of pan or rotation by entering another mode of operation.

### Claim 5 (depends on 3)

The near-to-eye display device of claim 3, wherein the sensor is an inertial sensor.

### Claim 6 (depends on 3)

The near-to-eye display device of claim 3, wherein the sensor is a six-axis inertial sensor.

### Claim 7

A near-to-eye display device comprising:
a camera for capturing images in a first field of view forward of a person wearing the device;
at least one display positioned near to an eye of the person wearing the device for displaying images captured by the camera in a second field of view, wherein the second field of view is smaller than the first field of view; and
a controller in communication with the camera and the at least one display for selecting a portion of the images from the camera to display on the at least one display, the controller being configured to automatically enter one of a plurality of display modes upon image analysis of the images captured by the camera, wherein in each display mode, the controller selects different regions of interest from the images to display on the at least one display, wherein the controller is configured to automatically enter a reading mode upon detecting reading material within the images captured by the camera.

### Claim 8 (depends on 7)

The near-to-eye display device of claim 7, wherein the controller selects a narrower field of view in the reading mode and a wider field of view in a non-reading mode.

### Claim 9 (depends on 7)

The near-to-eye display device of claim 7, wherein the controller is configured to automatically enter a TV/movie mode upon detecting that a user is watching a TV or a movie screen by analyzing the images captured by the camera.

### Claim 10 (depends on 9)

The near-to-eye display device of claim 9, wherein the controller is configured to select a region of interest to display corresponding to the size of the TV/movie screen when in the TV/movie mode.

### Claim 11 (depends on 9)

The near-to-eye display device of claim 9, wherein the controller is configured to perform image stabilization when in the TV/movie mode.

### Claim 12 (depends on 7)

The near-to-eye display device of claim 7, wherein the controller is configured to automatically enter a sport mode upon detecting that a user is watching a sporting event.

### Claim 13 (depends on 12)

The near-to-eye display device of claim 12, wherein the controller is configured to track a ball or puck in the images and to select a region of interest to display corresponding to the ball or puck when in the sport mode.
