Abstract: An image output device of a network-based intelligent service robot having a stereo camera is provided to calibrate a stereoscopic camera mounted in a robot by having a function of alternately outputting a left pre-processed image and a right pre-processed image one row by one row. The first image selecting unit(1152) selects one of a left camera image and a left pre-processed image. The second image selecting unit(1153) selects one of a right camera image and a right pre-processed image. A left/right image alternately processing unit(1151) alternately outputs the left pre-processed image and the right pre-processed image one row by one row. The third image selecting unit(1154) selects one of the alternately outputted image and a pose-processed image. The first line/frame memory unit(1156) stores and outputs of the first and second image selecting units at 1/4 quadrant and 2/4 quadrant. The second line/frame memory unit(1157) stores and outputs an output of the third image selecting unit and a stereo-matched image to a 3/4 quadrant and a 4/4 quadrant. A resolution matching unit(1155) matches resolution of the outputs of the first to third selecting unit and the stereo matched image, and displays the images of the first and second line/frame memory units as 4-divided screen images.
