Abstract
Abstract A graphic processing method in which a processing unit of a graphic input device is constituted by a computer, and a plurality of processing programs are stored beforehand in a memory of a host device. A predetermined processing program in accordance with the graphic processing to be executed in the graphic input device is transferred from the host device to a rewritable memory of the graphic input device, and graphic processing is executed by the graphic input device on the basis of the transferred processing program.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
138 words
A graphic processing method for entering data into a host computer from a graphic input device and executing predetermined processing based on the entered graphic data, in which a processing unit in the graphic input device for entering the graphic data into the host computer comprising a computer, said method is characterized by a first step of storing a plurality of processing programs in a memory of the host computer, a second step of requesting a predetermined processing program in accordance with graphic processing to be executed in the graphic input device, a third step of transferring the requested processing program from the host computer to a rewritable memory of the graphic input device, and a fourth step of executing graphic processing based on the transferred processing program and entering the obtained graphic data into the host computer.
Claim 2
Dependent Claim
138 words
A graphic processing method for entering data into a host computer from a graphic input device and executing predetermined processing based on the entered graphic data, in which a processing unit in the graphic input device for entering the graphic data into the host computer comprising a computer, said method is characterized by a first step of storing a plurality of processing programs in a memory of the host computer, a second step of requesting a predetermined processing program in accordance with graphic processing to be executed in the graphic input device, a third step of transferring the requested processing program from the host computer to a rewritable memory of the graphic input device, and a fourth step of executing graphic processing based on the transferred processing program and entering the obtained graphic data into the host computer.
Claim 3
Dependent Claim
78 words
A graphic processing method according to claim 1, said fourth step including a step of entering point data into the graphic input device, a step of converting said point data into graphic data indicative of line segments, circular arcs as well as curves composed of line segments and circular arcs, in accordance with a processing program stored in the rewritable memory of said graphic input device, and a step of entering this graphic data into the host computer.
Claim 4
Dependent Claim
31 words
A graphic processing method according to claim 2, including a step of defining sense by the point data input sequence, and employing said sense as a portion of the graphic data.
Claim 5
Dependent Claim
122 words
A graphic processing method for drawing a graphic obtained by executing predetermined graphic processing based on graphic data entered from a host computer, in which a processing unit in a graphic output device for drawing a graphic is constituted by a computer, said method comprising a first step of storing a plurality of processing programs in a memory of the host computer, a second step of requesting a desired graphic processing program in accordance with graphic processing to be executed, a third step of transferring the requested processing program from the host computer to a rewritable memory of the graphic output device, and a fourth step of executing graphic processing based on the transferred graphic processing program, thereby to draw a graphic.
Claim 6
Dependent Claim
122 words
