Abstract: The present disclosure relates to an imaging lens, a camera module and an electronic device including the same. The imaging lens according to an embodiment of the present disclosure includes a catadioptric lens on which light is incident from an object side, and through which light is reflected and emitted from the inside; and a lens group including a plurality of lenses for transmitting the light emitted from the catadioptric lens to an image surface, wherein the catadioptric lens includes: an incident surface on which light is incident from the object side; a second mirror surface which is formed concave toward the object side, and reflects the light incident on the incident surface to a first mirror surface in the object side; the first mirror surface which is formed, at a central portion of the incident surface, convex toward an image side, and reflects the light reflected from the second mirror surface toward the image side; and an exit surface through which the light reflected from the first mirror surface is emitted, wherein all of the lens group is disposed between the first mirror surface and the second mirror surface based on an optical axis. Accordingly, it is possible to increase the brightness of the lens, increase resolution, suppress an increase in thickness, and reduce tolerance due to mirror assembly.

Abstract: A driver assistance apparatus and a vehicle including the same are disclosed. The driver assistance apparatus includes a stereo camera and a processor to perform a calibration based on first regions that include objects for vehicle structures or external to the vehicle in stereo images acquired by the stereo camera in a calibration mode and to detect a distance to an object ahead of the vehicle based on second regions not including the objects for the vehicle structures in the stereo images acquired by the stereo camera in a normal mode. Consequently, it is possible to accurately perform distance detection based on images photographed by the stereo camera.
