Claim:
1. An information input/display device, comprising: a sensor detecting contact and outputting contact positions; a display displaying video signals corresponding to one screen; a first drawing component, including a processor, generating first video signals corresponding to the one screen that, when displayed, include an image of a drawing of a continuous line formed by the contact positions; a second drawing component, including hardware circuitry, generating second video signals each corresponding to an image of the drawing of the continuous line, the second drawing component generating images of the drawing of the continuous line at a higher speed than the first drawing component; an adder adding each of the second video signals to a corresponding one of the first video signals; and a setting information storage acquiring and storing therein setting information indicating luminance of the drawing of the continuous line, wherein images of the drawing of the continuous line generated by at least one of the first drawing component and the second drawing component change as time elapses in drawing processing, wherein luminance of the images of the drawing of the continuous line generated by the at least one of the first drawing component and the second drawing component changes as time elapses in the drawing processing such that luminance of the video signals displayed by the display, which are acquired through the adding by the adder, does not exceed the luminance indicated by the setting information, wherein the second drawing component includes wherein the memory, when provided with a notification of a pixel position in a given one of the first video signals, outputs a pixel signal corresponding to the pixel position, from among a plurality of pixel signals composing one of the second video signals corresponding to the given one of the first video signals, wherein the first drawing component changes images of the drawing of the continuous line to become darker in tone as time elapses in the drawing processing, and wherein the second drawing component changes images of the drawing of the continuous line to become lighter in tone as time elapses in the drawing processing.
