摘要： An optical scanning device, a driving method of an optical scanning device, and an image drawing system that can constantly maintain a frequency ratio between a frequency of a first driving signal and a frequency of a second driving signal in a case of changing the frequency of the first driving signal and the frequency of the second driving signal are provided. A driving controller provides a first driving signal having a first driving frequency corresponding to a first set value to a first actuator, provides a second driving signal having a second driving frequency corresponding to a second set value to a second actuator, changes the first driving frequency by changing the first set value in units of a first number obtained by dividing the first set value by a greatest common divisor of the first set value and the second set value, and changes the second driving frequency by changing the second set value in units of a second number obtained by dividing the second set value by the greatest common divisor.

摘要： The invention relates to a laser pointer (1) for continuously drawing arbitrary shapes on a surface, comprising:
a MEMS mirror (14) configured to deflect an emitted laser beam (3, 8, 12), wherein the deflection angle (Φ) of the MEMS mirror (14) can be altered by means of applying a set of drive values (DV) to the MEMS mirror (14);
an orientation measurement unit (18) configured to continuously determine a current orientation (θ i ) and to output said current orientation (θ i ) at an output (20);
a memory (19) being configured to store current orientations (θ i ) received from the orientation measurement unit (18) as a set (S, S', S") of orientation samples (22); and
a drive circuit (25) configured to generate said set of drive values (DV) by subtracting the current orientation (θ i ) from the set (S, S', S") of orientation samples (22) and to apply said set of drive values (DV) to the MEMS mirror (14).

摘要： Provided is a video display device that can be miniaturized and can gradually change brightness of each gradation value of a video. The video display device includes a laser light source unit that changes an amount of emitted light depending on a drive current, a video processing unit that outputs a video gradation signal, a current gain signal, and a current offset signal, a laser driver that outputs the drive current based on the video gradation signal, the power supply gain signal, and the current offset signal, and a dimming level processing unit that divides a dimming level for designating brightness of a video into a plurality of dimming modes and divides the dimming level into in-mode levels within the divided dimming modes, wherein the video processing unit includes a video gradation value output unit that outputs the video gradation signal obtained by scaling and offsetting a gradation value of the video based on the dimming mode and the in-mode level, a current gain output unit that outputs the current gain signal depending on the dimming mode, and a current offset output unit that outputs the current offset signal depending on the dimming mode.
