A method for determining presence of water droplets at an outer side of a vehicle windshield includes equipping a vehicle with a vehicular vision system having a camera disposed behind an inner side of the vehicle windshield so as to view exterior of the vehicle through the windshield. The camera includes a primary lens, a secondary lens and an imager, which has a primary sensing area and a secondary sensing area. Image data representative of images focused at the imager by the primary lens is captured at the primary sensing area of the imager. Image data representative of images focused at the imager by the secondary lens is captured at the secondary sensing area of the imager. Responsive to processing at the control of image data captured by the imager at the secondary sensing area, presence of water droplets at the outer side of the windshield of the equipped vehicle.
