<P>PROBLEM TO BE SOLVED: To provide a display device and a display method, clearly indicating the position of light applied to a screen by an instructing device for irradiating light. <P>SOLUTION: A light receiving position determination unit 19 adds a value of a coordinate (X, Y) of a pixel having the intensity of obtained receiving light determined to be greater than a predetermined value, to the N-th light receiving data Lpos. An instruction pointer display data creating unit 20 determines the light receiving color of the N-th light receiving position according to the light receiving data Lpos and the light receiving color of each pixel data, and copies the basic coordinate data on the pointer size and the pointer shape corresponding to the determined light receiving color to the coordinate data on the instruction pointer data. When the L color corresponding to the light receiving color is "3", the light receiving color of each pixel data is set as the color data on the instruction pointer data, and when the L color is under "3", the value of L color is set to the color data on the instruction pointer data. A CPU 15 displays an instruction pointer of the color, the size and the shape indicated by the instruction pointer data at the position indicated by the coordinate data. <P>COPYRIGHT: (C)2010,JPO&INPIT |
