<p>A stereo camera system is constituted of a stereo optical module (1) for obtaining a stereo image, a central control unit (3) for evaluating an object in the stereo image obtained by the stereo optical module (1), and a communication line (2) for causing stereo image data outputted from the stereo optical module (1) to be inputted into the central control unit (3). An image output processing circuit (8) for applying a predetermined image processing to the stereo image obtained by the stereo optical module (1) is provided in the stereo optical module (1). The stereo optical module (1) causes the image output processing circuit (8) to perform correction calculation for correcting imbalance occurred when the stereo image is imaged.</p>
