This is a data input and display method that displays the data in color at the .

[Industrial application field]

The present invention relates to a data input and display method for processing and displaying output signals of a pointing device in a drawing system using computer graphics technology.

[Conventional technology]

In a pointing device that has the function of detecting and outputting the position coordinates of a stylus pen such as a tablet or the function of detecting and outputting the amount of movement such as a mouse, it is possible to output analog signals other than the position signal or movement amount signal as well. It seems that no method has been disclosed so far for color processing and displaying the analog signal at the coordinate position.

[Problem that the invention seeks to solve]

In view of the dissatisfaction of display information mainly due to the expression of only shapes in conventional methods, the present invention is based on the concept of adding and displaying information other than coordinate signals as color information, and has developed a paper drawing system using computer graphics technology. The goal is to allow users to draw with colored pencils or Frepas on a canvas.

[Means for solving problems]

The system of the present invention includes a pointing device 1, a data input device 2, and a data display device 3. The pointing device 1 has a function of generating an analog signal in addition to generating a first digital signal representing a coordinate position or a movement amount signal. The data input device 2 receives the first digital signal and the analog signal and converts the analog signal into a second digital signal. Then, both the first digital signal and the second digital signal are output. The data display device 3 receives the output of the data input device 2,
Color display is performed at the position of the data display device 3 indicated by the first digital signal with brightness or hue associated with the value of the second digital signal corresponding to the first digital signal.

[For production]

By using the above-mentioned method according to the present invention, in addition to the shape information from the pointing device 1, it is possible to display analog signals such as data on the pressing force of a light pen in correspondence with the brightness or hue of the color signal. It becomes possible to supply a large amount of information.

〔Example〕

A block circuit diagram of a data input and display system according to one embodiment of the present invention is shown in FIG. This system comprises a pointing device 1, a data input device 2, and a data display device 3.

The pointing device 1 includes, for example, a tablet having a stylus pen 41 as shown in FIG. 2 or a mouse 45 as shown in FIG. 3. When the stylus pen 41 of the tablet is moved on the tablet surface 42, its coordinate position is detected by the pickup coil 12, and a coordinate position digital signal is output. The stylus pen 41 also includes a pick pressure detection section 11, and generates an analog signal in accordance with the pressing pressure. The mouse 45 has a ball (not shown) that is rotatable in all directions, the movement position can be calculated based on the direction and distance of rotation of the ball, and a digital signal corresponding to the output of the big amplifier coil 12 is output. The mouse 45 has a switch 46, and outputs an analog signal corresponding to the output of the above-described shock pressure detection section 11 in response to the pressure with which the switch 46 is pressed by the operator.

The data input device 2 includes an analog/digital (A/D) converter 21, a digital data detection section 22, a coordinate data detection section 23, a control section 24, and an input/output control section 25. The A/D converter 21 receives the output of the pick pressure detection section 11, converts the analog signal into a digital signal, and supplies the digital signal to the digital data detection section 22. pickup coil 1
The digital signal from 2 is supplied to the coordinate data detection section 23. Digital signals from the digital data detection section 22 and the coordinate data detection section 23 are supplied to the data display device 3 via the input/output control section 25, respectively. The control section 24 controls the digital data detection section 22, coordinate data detection section 23, and input/output control section 25 described above.

The data display section 3 includes an input/output control section 30, a digital data detection section 31, a coordinate data detection section 32, a drawing section 33, a drawing memory 34, a color table 35, a display control section 36, a color table creation section 37, a CRT (cathode ray tube) display device 38,
and a main control section 39. The output of the data input device 2 is supplied to an input/output control section 30. Input/output control section 3
The output of 0 is divided into a pressure signal and a coordinate signal, and the pressure signal is supplied to the digital data detection section 31 and the coordinate signal is supplied to the coordinate data detection section 32.

The color table creation section 37 inputs the reference color and mode.
For example, if the standard color is red and the mode is hue, a table of colors with m steps of hue changed around the standard color red is created,
It is stored in the color table 35.

If the mode is set to brightness, a table is created in which only the brightness is changed in m steps around the standard color red, and color table 35 is created.
Store in.

The drawing section 33 receives the coordinate data from the coordinate data detection section 32 and the A/D converted digital data from the big pressure detection section 11 via the digital data detection section 31, and creates a color table 35 based on the values of the digital data. The drawing memory 34 is set to draw a specific figure in the selected drawing color at the CRT display position corresponding to the coordinate data.

The CR7 display device 38 is controlled by the contents of the drawing memory 34 and the display control unit 36 to display a color selected from the color daple 35 at a position corresponding to the coordinate data using a digital value corresponding to the pick pressure. A main control 39 controls the entire system.

For example, when the mode is set to brightness, the threshold value that divides the digital data value of the stylus pen's big pressure into m pieces can be made to correspond to the brightness, so when you draw a figure on the tablet surface with the stylus pen, the pick The brightness of the color of the figure changes according to the pressure, and the figure displayed on the CRT display device can be drawn in the same way as when drawing with a frebus.

〔Effect of the invention〕

According to the present invention, in a drawing system using computer graphics technology, it is possible to draw a drawing with the feeling of drawing on paper or canvas with a colored pencil or a blank pass.
