PURPOSE:To simultaneously execute the affine transformation and the synthesis of a picture by simultaneously affine transforming picture information and a mask signal, associating and storing them. CONSTITUTION:When the mask signal M has a logic 1, the signal of a terminal A is outputted to a terminal Y in data selectors 4-11 according to the control of a data multiplexer 3. Therefore, an input signal B (base picture signal) and the mask signal M are inputted to a first FIFO (first in and first out) 19 through the selector 11 and the output of a i-th FIFO is inputted to a (i+1)th FIFO. When the mask signal M has a logic 0, the signal of the terminal B is similarly outputted to the terminal Y only in a k-th data selector. Therefore, only the k-th FIFO is rewritten by the affine transformed input signal A and the synthesized picture of the base picture and the input signal A is outputted from an FIFO 12. |
