Abstract:

In order to obtain a low-cost stereo camera which can decrease the load of software-based calibration, a stereo camera (1) is provided with a first vehicle-mounted camera (11R) which comprises a first lens unit (12R) and a first imaging element (32R), and a second vehicle-mounted camera (11L) which comprises a second lens unit (12L) and a second imaging element (32L). This stereo camera is characterized in that the first imaging element (32R) has a first sensitivity value recording unit (33R) in which sensitivity values of the first imaging element (32R) are recorded, and the second imaging element (32L) has a second sensitivity value recording unit (33L) in which sensitivity values of the second imaging element (32L) are recorded, wherein the sensitivity variation width between the sensitivity values of the first imaging element (32R) recorded in the first sensitivity value recording unit (33R) and the sensitivity values of the second imaging element (32L) recorded in the second sensitivity value recording unit (33L) is within a preset reference width.
