![]() T total: the total of the delay time for one frame calculated for each vector-data according to equation (a).ġ6. FPS = 1 T total ( b ) FPS: the update rate for each frame drawing in frame per second. The method of drawing vector-oriented graphic for laser projector of claim 14, wherein FPS, which is the update rate for each frame drawing in frame per second, is calculated by using the equation (b). T = D v ( a ) T: the time assigned for the beam to move from the start point to the end point of a vector. The method of drawing vector-oriented graphic for laser projector of claim 13, wherein the above-mentioned delay time T is calculated by using the equation (a). The method of drawing vector-oriented graphic for laser projector of claim 11, wherein the above-mentioned delay time includes a delay time occurred between when the command is seen by the X-Y scanner and when the mirror of the X-Y scanner actually moves into position specified by the command.ġ4. The method of drawing vector-oriented graphic for laser projector of claim 11, wherein parameters of the scanning speed, the scanning angle, the delay time, and the blanking time are included to achieve tuning to the X-Y scanner in real time with freely setting the numerical value of each parameter.ġ3. 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.ġ2. ![]()
