Abstract
An apparatus and method are provided for displaying an image by raster scanning using a mirror. The apparatus includes a mirror control unit that controls a vertical motion of the mirror to be a triangle wave motion, and a scanning unit that repeatedly performs a forward scan and a reverse scan over the mirror in an orthogonal direction. The apparatus can reduce ringing by controlling the vertical motion of the mirror to be an isosceles triangle wave motion and increasing a sawtooth flyback time to about 50%. Also, since the reverse scan is performed during flyback after the forward scan is performed, the apparatus can compensate for a reduction in screen brightness, which is caused by the increase of the sawtooth flyback time to about 50%.
Claims13
An apparatus for displaying an image by raster scanning using a mirror, the apparatus comprising:
- a mirror control unit which controls a vertical motion of the mirror to be a substantially triangular wave motion;
- and
- a scanning unit which repeatedly performs a forward scan and a reverse scan over the mirror in a substantially orthogonal direction.
A method of displaying an image by raster scanning using a mirror, the method comprising:
- controlling a vertical motion of the mirror to be a substantially triangle wave motion;
- and
- repeatedly performing a forward scan and a reverse scan over the mirror in a substantially orthogonal direction.
A computer-readable recording medium having embodied thereon a program for performing a method of displaying an image by raster scanning using a mirror, the method comprising:
- controlling a vertical motion of the mirror to be a substantially triangle wave motion;
- and
- repeatedly performing a forward scan and a reverse scan over the mirror in a substantially orthogonal direction.
