ABSTRACT:
Accurate drawing without position displacement is performed irrespective of different aspect ratios on the transmission side of drawing information and on the reception side. In a drawing apparatus50, a normalized coordinate transformation section62transforms normalized coordinates (x3, y3) transmitted via a network into rear coordinates (x2, y3) in accordance with an inverse function g1−1of a function g1for normalizing an aspect ratio of an image displayed on a display, and a rear coordinate transformation section63transforms the rear coordinates (x2, y2) into front coordinates (x1, y1) in accordance with an inverse function f1−1of a function f1corresponding to the aspect ratio of the image. A drawing section67draws an image on the screen of the display in accordance with the front coordinates (x1, y1). The invention is applicable, for example, to an application sharing drawing information.
