摘要： 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.

摘要： Disclosed herein are a dust measuring apparatus and a mobile terminal for controlling the same. The dust measuring apparatus includes a flow channel defining unit for defining a flow channel allowing a fluid containing dust to move through, a light emitter for emitting light into the flow channel, a light detector for detecting light scattered from the dust in the flow channel and converting the same into an electrical signal, and a controller for controlling the flow channel defining unit, the light emitter and the light detector. The controller is configured to verify whether a detection value received from the light detector is within an effective measurement range, vary the effective measurement range when the detection value is outside the effective measurement range, and measure, when the detection value is within the varied effective measurement range, a dust concentration based on the detection value.
