    Abstract: A method and an apparatus are provided for processing an image of an image signal projected through a digital camera lens. The apparatus includes an image sensor module to transform an optical signal projected through the digital camera lens into an electric signal, to generate and output an image signal. The apparatus includes a light receiving module to receive a light source, wherein the light receiving module is disposed close to the image sensor module. The apparatus also includes a light source characteristic detector to detect a frequency of the light source received by the light receiving module. The apparatus further includes an auto color adjustment controller to identify a kind of light source based on the frequency of the light source, and control a white balance gain of the image signal based on the kind of the light source.

    Abstract: An apparatus and a method for generating a motion blur in a mobile terminal are provided. It is determined whether motion halting occurs during video shooting. If the motion halting occurs, a motion vector of each block between first and second consecutive images where the motion halting has occurred is estimated. A motion blur is generated on the second image using the motion vector of each block, and the motion-blurred image is displayed on a display unit.
