A stereoscopic display controller supplies serial picture element data to
a scanned stereoscopic display which comprises a plurality of picture
elements. Each of the picture elements includes image data for M color
components, while M is greater than one. The stereoscopic display
controller includes: N memories, N being an integer greater than one; a
memory controller arranged to write the picture element data for N
different views of a three-dimensional image in the respective memories,
and arranged to control reading of the memories in turn so that image
data for consecutively scanned picture elements of the display are read
from different ones of the memories; and a data reordering circuit
coupled to outputs of the memories and arranged to reorder the image data
for at least one of the color components.
