IN-VEHICLE SYSTEM AND IN-VEHICLE DEVICE

It is possible to cope with a deviation of a relative position between a headlight and an in-vehicle camera. An in-vehicle system includes: an irradiation unit that irradiates an area other than a set light-shielding range with light; an imaging unit that images a range including an irradiation range of the light emitted by the irradiation unit to acquire a captured image; an object detection unit that detects a non-target object which is not to be irradiated with the light from the captured image; a direct irradiation prevention unit that calculates the light-shielding range on the basis of a position of the non-target object in the captured image and correction information, and sets the light-shielding range in the irradiation unit; a correction-time light-shielding range setting unit that sets the predetermined light-shielding range in the irradiation unit; and a correction calculation unit that calculates the correction information on the basis of the captured image when the correction-time light-shielding range setting unit sets the light-shielding range in the irradiation unit.
