PURPOSE:To obtain a circuit which can paint out an image at a high speed, by converting outline bit information of an image to paint-out information by an outline bit generating part, etc. for supplying successively said information by setting adjacent N bits on the same line as a unit. CONSTITUTION:The decoding part 11 of an outline bit information generating part 1 decodes and reproduces outline bit information based on an outline data supplied from the outside, stores it in a memory 12, and an output part 13 outputs outline bit information generated based on said information by setting adjacent N bits on the same line as a unit. A paint-out information generating part 2 is provided with a converting part 21 to which processing units of N stages are connected in a shape of a cascade, and a latching circuit 22 for latching temporarily its output, and based on the outline bit information of N bits supplied from the pre-stage, paint-out bit information related to a section corresponding to its N bit information is outputted in parallel. A write circuit 3 writes information outputted successively from the paint-out information generating part 2, in a prescribed address of a memory 4, and a paint-out data is reproduced. |
