  • Graphic processing apparatus
    Patent number: 5889531
    Abstract: In a program storing unit (14), a dedicated processing program relating to at least one type of specific graphic data in the plurality of types of graphic data and a general purpose processing program which can deal with all of the plurality of types of graphic data are stored. A counting unit (16) counts the number of the specific graphic data included in the graphic data stored in the graphic storing unit. A processing unit (18) compares the counted number of the specific graphic data counted by the counting unit with a predetermined reference value. When the counted value is larger than or equal to the reference value, all of the graphic data are processed by the dedicated processing program, and the graphic data, which cannot be dealt with by the dedicated processing program, are processed by the general purpose processing program. When the count value is less than the reference value, all of the graphic data are processed by the general purpose processing program.
