<p>PURPOSE:To draw a picture in such a sense as drawing a picture on paper or a canvas with a colored pencil or crayon pastel, by providing a digital data detecting part, a coordinate data detecting part, a picture drawing part and a color table, etc., on a data display device. CONSTITUTION:An input from a pointing device 1 is supplied to an input/output control part 30 through a data input device 2, and a pressure signal and a coordinate signal are outputted to a digital data detecting part 31, and a coordinate data detecting part 32, respectively. Subsequently, a picture drawing part 33 inputs a coordinate data from the detecting part 32 and a digital data from a pick pressure detecting part 11, from the detecting part 31, selects one from a color table 35 by a value of the digital data, and sets a picture drawing memory 34 so as to draw a picture on a display position of a CRT corresponding to the coordinate data. A CRT display device 38 executes a display by a color selected from the table 35, based on the digital value corresponding to the pick pressure, on a position corresponding to the coordinate data, by the contents of the memory 34 and a control of a display control part 36. In such a way, a picture can be drawn in such a sense as drawing a picture on paper or a canvas with a colored pencil, etc.</p> |
