Method and apparatus for displaying images
First Claim
Patent Images
1. A method of displaying images using an image display device having two displays, each display being arranged in the image display device so as to be capable of presenting an image to an eye of a user, the method comprising:
- dividing image signal data into a first portion, the first portion comprising a first reduced data set defining the entire image, and a second portion, the second portion comprising a second reduced data set defining the entire image, the first portion differing from the second portion;
generating a right display signal using the first portion of the image signal data;
generating a left display signal using the second portion of the image signal data;
transmitting the right display signal to a right one of the displays;
transmitting the left display signal to a left one of the displays;
displaying a right image on the right display from the right display signal; and
displaying a left image on the left display from the left display signal, substantially simultaneously with the displaying of the right image;
wherein the image signal data includes data capable of describing a source image arrangeable into an array of columns and rows, the step of dividing image signal data comprising;
selecting a right set of image data values from the image signal data corresponding to selected points on the array of the source image, the right set of image data values being used to form the first portion of the image signal data; and
selecting a left set of image data values from the image signal data corresponding to selected points on the array of the source image, the left set of image data values differing from the right set of image data values, and being used to form the second portion of the image signal data;
wherein the step of selecting a left set of image data values includes the step of selecting image data values of which none are included in the right set of image data values.

Abstract
A method and apparatus for displaying images are addressed to displaying differing images to the right and left eyes of a user. A right image is presented to the user'"'"'s right eye by a right display, and a left image is presented to the user'"'"'s left eye by a left display. When the user'"'"'s brain processes the right and left images, it performs binocular summation on the two images, and perceives a composite image containing more information than either of the right and left images.

1. A method of displaying images using an image display device having two displays, each display being arranged in the image display device so as to be capable of presenting an image to an eye of a user, the method comprising:
-
dividing image signal data into a first portion, the first portion comprising a first reduced data set defining the entire image, and a second portion, the second portion comprising a second reduced data set defining the entire image, the first portion differing from the second portion; generating a right display signal using the first portion of the image signal data; generating a left display signal using the second portion of the image signal data; transmitting the right display signal to a right one of the displays; transmitting the left display signal to a left one of the displays; displaying a right image on the right display from the right display signal; and displaying a left image on the left display from the left display signal, substantially simultaneously with the displaying of the right image; wherein the image signal data includes data capable of describing a source image arrangeable into an array of columns and rows, the step of dividing image signal data comprising; selecting a right set of image data values from the image signal data corresponding to selected points on the array of the source image, the right set of image data values being used to form the first portion of the image signal data; and selecting a left set of image data values from the image signal data corresponding to selected points on the array of the source image, the left set of image data values differing from the right set of image data values, and being used to form the second portion of the image signal data; wherein the step of selecting a left set of image data values includes the step of selecting image data values of which none are included in the right set of image data values. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. An image display device, the device comprising:
-
a controller arranged to utilize a first portion of image signal data to generate a right display signal, and to utilize a second portion of image signal data to generate a left display signal, the first portion of the image signal data and the second portion of the image signal data being obtained from a source image signal, the first portion comprising a first reduced data set defining the entire image, and the second portion comprising a second reduced data set defining the entire image; a right display operably connected to the controller to receive the right display signal and to utilize the right display signal to display a right image to a right eye of a user; and a left display operably connected to the controller to receive the left display signal and to utilize the left display signal to display a left image to a left eye of a user, wherein the right display signal differs from the left display signal. - View Dependent Claims (9, 10, 11, 12)

13. A method, comprising:
-
generating first and second sets of pixels from an input image using different portions of the input image; and providing the first and second sets of pixels to a left eye display and right eye display, respectively; wherein the input image comprises an array of pixels having rows and columns, and wherein generating the first and second sets of pixels comprises selecting different rows and columns of the input image when generating the first set of pixels than when generating the second set of pixels.

16. An image display device, comprising:
-
a left eye display; a right eye display; and a controller coupled to the left and right eye displays, wherein the controller receives an input image and, from the input image, generates a left eye image to be shown on the left eye display and a right eye image to be shown on the right eye display; wherein the controller generates the left and right eye images using portions of the input image, wherein the portion use to generate the left eye image differs from the portion used to generate the right eye image; wherein the input image comprises an array of pixels having rows and columns, and wherein the controller selects different columns of the input image when generating the left eye image than when generating the right eye image. - View Dependent Claims (17)

18. An image display device, comprising:
-
a left eye display; a right eye display; and a controller coupled to the left and right eye displays, wherein the controller receives an input image and, from the input image, generates a left eye image to be shown on the left eye display and a right eye image to be shown on the right eye display; wherein the controller generates the left and right eye images using portions of the input image, wherein the portion use to generate the left eye image differs from the portion used to generate the right eye image; wherein the input image comprises an array of pixels having rows and columns, and wherein the controller selects different rows and columns of the input image when generating the left eye image than when generating the right eye image.
