Patent ID: 6943799

Claim:
A gaze directed visual system, comprising: a gaze tracker for determining an area of interest; an image generator for generating an area of interest image about said area of interest and generating a background image; a pair of field buffers, comprising an odd field buffer and an even field buffer, for providing a composite image from said area of interest image and said background image; and a timing and control block for interleaving timing of read and write operations on said pair of field buffers wherein reading of said composite image commences upon completion of writing a first portion of said background image, whereby said composite image is displayed with minimized transport delay on a high resolution display device; wherein said timing and control block interleaves, between said odd field buffer and said even field buffer, timing of reading said composite image from said odd field buffer and timing of reading said composite image from said even field buffer; and wherein said reading from said odd field buffer occurs within a display field time commencing after a fixed time delay sufficient to allow time to write said area of interest image into said odd field buffer and said reading from said even field buffer occurs within a display field time commencing after a fixed time delay sufficient to allow time to write said area of interest image into said even field buffer.
