This vehicle-mounted image recognition device reliably detects moving bodies from the captured images even when the lens is dirty. An image capturing unit (10) arranged in the local vehicle (5) observes the periphery of the local vehicle (5) through a lens (12) and converts to an image signal the optical signal of the observed periphery of the local vehicle (5). From the images captured by the image capturing unit (10), a vehicle detection unit (70) (image recognition application execution unit) detects other vehicles (6) (moving bodies) present in the periphery of the local vehicle (5) with a prescribed detection sensitivity. Depending on how high the white turbidity (U) is, a detection sensitivity adjustment unit (50) adjusts the detection sensitivity of the vehicle detection unit (70) in the direction for improving the detection sensitivity. An adhesion degree calculation unit (26) calculates the adhesion degree (M) of adhering matter such as water droplets or mud adhering to the lens (12), and corrections are made on the basis of said adhesion degree (M) in said detection sensitivity adjustment unit (50).
