in each row of the left eye image are read out from the data buffer and written into odd numbered pixel ddrii in frame 1 second even numbered pixels in each row of the left eye image are read out from the data buffer and written into even numbered pixel ddrii in frame 1 third the odd numbered pixel data in frame 3 are read out from the ddrii and written to the output odd numbered pixel data buffer last the even numbered pixel data in frame 4 are read out from the ddrii and written to the output even numbered pixel data buffer there are also four actions in processing the even numbered row image for the left eye first odd numbered pixels in each row of the left eye image are read out from the data buffer and written into odd numbered pixel ddrii in frame 1 second even numbered pixels in each row of the left eye image are read out from the data buffer and written into even numbered pixel ddrii in frame 1 third the odd numbered pixel data in frame 4 are read out from the ddrii and written to the output odd numbered pixel data buffer last the even numbered pixel data in frame 3 are read out from the ddrii and written to the output even numbered pixel data buffer this completes the actions in the first sequence ln the second sequence rn processes odd numbered.
