A mobile terminal has an image corrector which includes a comparator for receiving a first image signal photographed by a camera in a camera mode and a second image signal displayed in a normal mode, and for comparing them with a reference signal to generate a deviation signal, and a corrector for receiving the deviation signal from the comparator, and for supplying the first or second image signal, in which white balancing and gamma are corrected, in response to the deviation signal so that luminance and white balance of the first image signal displayed in the camera mode become equal to or similar to luminance and white balance of the second image signal displayed in the normal mode.
