PURPOSE:To provide a picture drawing method capable of forming a character at high speed by way of reducing stand-by time of calculation of displacement amount dx, dy or stand-by time of writing in a memory in vector font picture drawing of a character outline using a straight line and a curved line. CONSTITUTION:Displacement amount dx, dy data calculated by a straight line generation means 1 or a curved line generation means 2 is input to a shift register 5, held as held data, and the held data output from the shift register 5 is inputted to a memory 8 in accordance with a memory address found by a memory address conversion means 6. The straight line and the curved line generation means 1, 2 calculate following displacement dx, dy by a reception advice signal 31 without waiting for a write-in completion advice signal, and the memory address conversion means 6 carries out following memory address conversion by the write-in completion advice signal without waiting for a generation advice signal 29. |
