Input device for graphic processing system

Abstract

Abstract PURPOSE:To correctly input a fine part while viewing the entirety of a drawing and to remarkably improve an operability at the time of an input by enlarging only the prescribed area in the circumference of a cursor and displaying on a screen on which already inputted graphic is displayed. CONSTITUTION:In a cursor peripheral area enlarging part 5, the enlarged area in the circumference of the cursor is calculated according to the coordinate value of the cursor inputted and instructed by a mouse or the like 4 in a step (ST) 11. Then, in a ST 12, the graphic of the enlarged area is segmented from displayed graphics, in a ST 13, the segmented graphic is enlarged and processed, in a ST 14, the enlarged graphic is displayed. At the time of having no input instruction, the operation is returned to the ST 11 to continuously execute the ST 11-ST 14, again. This continuous processing is repeatedly executed until the input of a coordinate is instructed. Thereby, according to the movement of the cursor, only the prescribed area in the circumference of the cursor is enlarged to move the area. At the time of instructing the input of the coordinate according to the decision of a ST 15, a processing is shifted to a coordinate inputting part 6.
