memory. As discussed in connection with claim 16, in the
"output raster scan mode," for the 0-degree rotation, the
words are read out from the page memory in sequential order
(words 1, 2, ...) and since the words are output in a serial
manner starting with the LSB, the bits of the word are output
as, for example, word 1, bit 0 (the LSB), bit 1, ..., bit 7
(the MSB), word 2, bit 0, bit 1, etc. The bits are not
subject to bit-order reversal or rotation (see figure 5 for 0E
under output raster scan mode) and would be written to a
display in the same order as read out from the page memory.
For the 180-degree rotation, the words are read out in an
inverse order (words 200, 199, ...). However, the bits are
subject to bit-order reversal in the circuit of figure 3 (see
figure 5 for 180E under output raster scan mode) and therefore
would be written to a display in a different order than they
were read out from the page memory. This is an artifact of
the fact that Kajihara is a word-based system and not a
bit-based system. Nevertheless, the rejection is based on
anticipation and must be reversed because Kajihara does not
meet the function of "scanning said image data to said video
