A camera module is advantageously used in a vision system mounted on an automotive vehicle. The camera module includes a first optical system focused on distant objects such as a preceding vehicle and scenery in front of a vehicle and a second optical system focused on close objects such as raindrops on a windshield. The first optical system includes a first convex lens, a mirror or a half mirror and an imager, and the second optical system includes a second convex lens and a mirror. The distant image formed by the first optical system and the close image formed by the second optical system are combined into a combined image made on the imager in a single frame. The distant and close images are taken at the same time without adjusting the focuses in the camera module.
