Abstract:
1. A camera module comprising: a first optical system including a first convex lens having a first focal distance, a half mirror positioned behind the first convex lens at an inclination relative to an optical axis of the first convex lens, part of light coming out from the first convex lens passing through the half mirror, and an imager positioned behind the half mirror and a second optical system including a second convex lens having a second focal distance which is different from the first focal distance and a mirror positioned behind the second convex lens at an inclination relative to an optical axis of the second convex lens, part of light coming out from the second convex lens being reflected on the mirror toward the half mirror so that the light reflected on the mirror is further reflected on the half mirror, wherein: a single image is made on the imager by combining a first image formed by the light passing through the half mirror with a second image formed by the light reflected on the half mirror, the first image and the second image being formed at the same time.
