A stereo camera accurately measures the parallax of an object in real time and an accurate distance, even in a device in which the vertical positions of two cameras are mutually offset. A left camera starts to capture an image. An image capturing region of a right camera is set to be below that of the left camera, and the start of image capture by the right camera is delayed. Image capture by the right camera starts after a time difference has elapsed. Feature points in images from the left and right cameras are extracted, and feature points in the vicinity of a height set in advance in the left and right images are extracted. Detection is performed to ascertain whether the average value of a left/right difference for a plurality of points is set in advance, and a difference at the current time is calculated.
