Image Drawing Method, Portable Terminal, and Computer Program

摘要

An image drawing method for drawing an image on an input screen of a portable terminal having input keys arranged in an NxM matrix includes the steps of: determining a size of an input window formed of grid squares arranged in an NxM matrix; determining a position of the input window on the input screen; displaying the input window of the size determined in the input window size determination at the position of the input screen, the position being determined in the input window position determination; and in response to user input being performed on one of the input keys arranged in the NxM matrix, performing a drawing process at the grid square corresponding to the position in the NxM matrix at which the user input has been performed.
