modulator (SLM) for generating an image. The invention is
particularly directed to a technique for processing two
different frames of video data at the same time.
Representative claim 1 is reproduced as follows:
1. A method of using a memory for storing data for
use in a display system having a processor for processing
pixel data and having a spatial light modulator (SLM) for
generating an image, comprising the steps of:
writing a first video frame of samples of pixel data
into said memory during a first frame period;
writing a second video frame comprised of samples of
pixel data to said memory during a second frame period, such
that each sample of said second video frame is written over
the corresponding sample of said first video frame;
reading said data from said memory in bit-planes;
repeating said reading step such that at least the
same number of bit-planes as the number of bits representing
each pixel intensity are read out during a display frame
period;
wherein one or more of the reading steps are performed
with data from said samples of said first video frame and data
from said samples of said second video frame;
delivering each of said bit-planes to said spatial
light modulator, wherein said spatial light modulator displays
such bit-planes as a display frame with said data from said
first video frame and data from said second video frame in
each said bit-plane and in each said display frame; and
wherein all of said steps are repeated to generate a
continuous display of images.
