Abstract
An apparatus and a method for aligning images obtained by a stereo camera apparatus are provided. The apparatus receives images from a first camera and a second camera and searches for a pixel block from an image obtained by one of the cameras (a non-reference camera) having the highest consistency ratio with a pixel block in a specific position of the image obtained by the other camera (a reference camera). Then, the apparatus changes a range of the region displayed on a screen among the image obtained by the non-reference camera according to the position of the searched pixel block to generate and output a stereoscopic image using an image having a screen display region focus of the respective cameras where the two cameras are aligned in the horizontal line.
