This distance measuring camera contains a first optical system for collecting light from a subject to form a first subject image, a second optical system for collecting the light from the subject to form a second subject image, an imaging unit for imaging the first subject image formed by the first optical system and the second subject image formed by the second optical system, and a distance calculating part 4 for calculating a distance to the subject based on the first subject image and second subject image imaged by the imaging part. The distance calculating part 4 calculates the distance to the subject based on an image magnification ratio between a magnification of the first subject image and a magnification of the second subject image.
