Abstract
The laser projector system draws vector-oriented graphic by scanning laser beam with the X-Y scanner, and comprises: a laser source (201) for projecting laser beam; a galvanometer scanner (202) for scanning laser beam with the X-Y mirror (203) to freely control the direction of laser beam; a scanner amp (205) for controlling projection output of laser beam; a scanner controller (204) for controlling the galvanometer scanner and the scanner amp; and a computer (207) connected to the scanner controller (204).

1-10. (canceled)
A method of drawing vector-oriented graphic for laser projector, which draws vector-oriented graphic by scanning laser beam with the X-Y scanner, wherein a method to tune scanning speed, delay time, and blanking time is included, comprising:
- transmitting one vector-data, for drawing vector-oriented graphic, to a X-Y scanner one by one;
- controlling the scanning speed of each vector-data;
- calculating the delay time and the blanking time corresponding to the scanning speed of each vector-data;
- deciding appropriate timing to compensate the above-mentioned delay time when the command for transmitting vector-data is issued;
- and deciding appropriate timing to compensate the above-mentioned blanking time when the command for switching off/on the laser for blanked line segments is issued.
