Claim:
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.
