Abstract

A portable graphic computer apparatus is comprised of a tablet for inputting coordinates data, a detecting circuit for detecting the coordinates data inputted by the tablet, a video image data forming circuit for forming video image data corresponding to input coordinates based on coordinates data by an output signal from the detecting circuit, a memory for storing the video image data, a video signal generating circuit for generating a video signal from the video image data, an output circuit connected to the video signal generating circuit for outputting the video signal, a cabinet for accommodating therein the above elements, and a plurality of color selecting buttons formed on the tablet for selecting color informations of the video image data, wherein the video image forming circuit identifies the designation of the color selecting buttons and for forming the video image data on the basis of the designated color.

Claims
