Abstract
Both downsizing of a device and improvement of the ranging accuracy are implemented in a device for measuring a distance to an object. An image capture device includes a pair of imaging elements and a ranging unit. Regarding the pair of imaging elements in this image capture device, axes perpendicular to light receiving surfaces thereof cross each other. Furthermore, in the image capture device including the pair of imaging elements and the ranging unit, the ranging unit measures a distance to an object on the basis of a parallax obtained from a pair of images captured by the pair of imaging elements in which axes perpendicular to light receiving surfaces thereof cross each other.
