IMAGE PROCESSING AND METHOD

摘要

The disclosure relates to high-speed image processing apparatus and a method for rotating two dimensional original images. Image processing apparatus as described includes a scaling means for responding to scaling values decided by a rotation angle to generate each pel row of a scaled image of the original image; means for responding to values of horizontal and vertical shears decided by the rotation angle to perform horizontal shear and vertical shear operations to generate an address in an output image memory into which the first pel of the pel row of the scaled image is stored; a line generator means for responding to the value of vertical shear and the address of the first pel to generate addresses in the output memory into which all the pels of the pel row of the scaled image are stored; and means for storing all the pels of the pel row in the addresses of the output image memory.
