Abstract
A mobile terminal and photographing method for the same are disclosed. The mobile terminal includes an optical section receiving optical signals, an image sensor comprising color sensor elements detecting sensing-image information from a transmitted optical signal, and infrared sensor elements detecting infrared-image information from the transmitted optical signal and an image processing unit producing infrared-image information of the color sensor elements, using the detected infrared-image information.
