ABSTRACT:
A two-dimensional image information display apparatus in which an image of coordinates of display points which coincide with coordinates of designated point of input data is obtained on the display screen comprises laser beam source radiating a laser beam, drive signal generator generating a drive signal in accordance with the input data carrying the coordinates of designated point, and deflector for deflecting an angle of the laser beam in accordance with the drive signal, for irradiating the deflected laser beam onto the display screen, thereby obtaining a display point. The drive signal generator has memory for storing coordinates of reference points, memory for storing errors representing deviations of coordinates of a display point which are obtained when the coordinates of a reference point are used as the coordinates of a designated point from the coordinates of the reference point, interpolating device for producing errors corresponding to the coordinates of the designated point as interpolation errors by an interpolating method, and converting device for converting the coordinates of the designated point by the interpolation errors, and producing converted coordinates, so that the converted coordinates are used as the input data.
