A laser ranging unit is rotatably attached to a camera body by a hinge unit. The camera body has a first imaging unit and a laser radiation position specification unit. The laser ranging unit has a laser radiation unit, a laser receiving unit, a second imaging unit, and a distance calculation unit. The first imaging unit images a first range to generate a first image. The laser radiation unit is able to radiate a laser beam in an arbitrary direction within the first range. The laser receiving unit receives a reflected beam of the laser beam. The second imaging unit images a second range including a radiation position of the laser beam within the first range to generate a second image. The laser radiation position specification unit searches for a portion matching the second image in the first image to specify the radiation position in the first image. The distance calculation unit calculates the distance to the radiation position based on the time of receiving the reflected beam. |
