Abstract

PURPOSE:To eliminate a compensation for the detection information of light pen in a higher-rank device or a softward and increase the accuracy of detection, by installing a light pen register, a light pen compensation register, a subtraction part and a compensation value set FF each. CONSTITUTION:Prior to an operation of the light pen, the compensation value set FF20 is to secure a compensation value setting enable mode. Thus the characters/ symbols at the ''0'' position of character address are displayed on the screen of the dispaly part 13. The light pen 14 is applied to the position of the above display, and the reproduction buffer address output of the refresh counter 6 is set to the light pen compensation register 18 in the form of a correction value. At the same time, the compensation value setting enable mode is secured with the light pen is operated. Then the value obtained by subtracting the storage value of the register 18 from the storage value of the light pen register 16 is given to a higher-rank device in the form of a light pen touch position.
