<p>PURPOSE:To rotate easily an image at 270 deg., by reading and writing words in the reverse order of address. CONSTITUTION:Respective picture elements are allowed to correspond bits and are expressed in a digital form, and words of partial image data 11 divided to square divisions of n-number of bits X n-number of words where the length of one word is n-number of bits are read out in the reverse order of address, and words are written in the reverse order of address again after the processing of the rotation at 90 deg., thus performing the processing of the rotation at 270 deg..</p> |
