GRAPHIC DECODER INCLUDING COMMAND BASED GRAPHIC OUTPUT ACCELERATING FUNCTION, GRAPHIC OUTPUT ACCELERATING METHOD THEREFOR, AND IMAGE REPRODUCING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a graphic decoder including a command based graphic output accelerating function, a graphic output accelerating method therefor, and an image reproducing apparatus, which improve an output processing function of two-dimensional graphic images to be improved by utilizing a graphic output accelerating command utilizing horizontal line drawing.;SOLUTION: The graphic output accelerating method includes a step of interpreting graphic data to convert it to at least one accelerating command data and storing this data and a step of executing at least stored accelerating command data to output graphic image, and independently performed graphic output is accelerated in each step. Especially, it is preferable that accelerating command data includes at least one horizontal line draw command or vertical line draw command for quickly drawing a graphic image on a screen, which results from interpreting graphic data to generate a polygon and performing scan conversion of the generated polygon.;COPYRIGHT: (C)2005,JPO&NCIPI
