Abstract

PURPOSE:To specify a detailed position on a screen, by detecting the rough position on the screen in the front one of two continuous fields with the rear field surrounding the area near the rough position to display the position with a certain brightness and then using the output signal of a light pen through the display. CONSTITUTION:The light pen is under the indicating action; and in the rear field among the two continuous fields, a scan is given to the range concerning the horizontal direction of x'-alpha-x'-x'-alpha+gamma.g(t) including the X coordinates x' that is within the region concerning the vertical direction of Y'-beta-y'-y'-beta+delta.e(t) including the Y coordinates y' of the point P'(x', y') detected in the front field as a rough position meanwhile the signal gamma has a high level, and the hatched region H is displayed with a certain brightness and in a certain color. Such region is then written into the corresponding memory in the form of an accurate information about the indicated position the light pen detected.
