Abstract: An image projection module, a mobile device including the image projection module, and a method for operating the same are disclosed. A method for operating a mobile device including an image projection module includes splitting an input image into a left-eye image and a right-eye image in a three-dimensional (3D) image display mode, driving left-eye and right-eye light sources for outputting light having different wavelengths based on the left-eye image and the right-eye image, synthesizing light output from the left-eye light source and light output from the right-eye light source, and projecting the synthesized light in a first direction and then a second direction. Therefore, it is possible to conveniently display a three-dimensional (3D) image.

Abstract: A projector and an apparatus and method for driving an optical scanner are disclosed. A sensing signal processor receives a sensing signal that represents sensing of operation of the optical scanner and generates a horizontal scan signal corresponding to a horizontal frequency of the optical scanner on the basis of the received sensing signal. A driving signal generator generates at least one of a horizontal reference signal including line information that indicates the number of horizontal lines of a horizontal driving signal of the optical scanner, a reference clock signal and a scanner driving signal for driving the optical scanner on the basis of the generated horizontal scan signal.
