Abstract:
1. A method for operating a mobile device including an image projection module, the method comprising: 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; projecting the synthesized light in a first direction and then a second direction, and performing signal processing such that a color region of the light output from the left-eye light source and a color region of the light output from the right-eye light source become equal, in the 3D image display mode, wherein the wavelength band of light output from the left-eye light source is separated from the wavelength band of light output from the right-eye light source, wherein the wavelength of the light output from the left-eye light source is shorter than the wavelength of the light output from the right-eye light source, and wherein a signal level of a right-eye color signal applied to the right-eye light source is higher than a signal level of a left-eye color signal applied to the left-eye light source.
