In-vehicle system and in-vehicle device

A correction device which is mounted on a vehicle including an irradiation unit that irradiates an area other than a set light-shielding range with light and an imaging unit that images a range including an irradiation range of the light emitted by the irradiation unit to acquire a captured image, the correction device comprising:

• an acquisition unit that acquires the captured image from the imaging unit;
• 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 a 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, wherein the light-shielding range comprises a predetermined angle range;
• a correction-time light-shielding range setting unit that sets, as the predetermined light-shielding range in the irradiation unit, an area which is symmetrical with respect to at least one of a horizontal direction and a vertical direction in front of the irradiation unit, wherein the area is set with respect to the horizontal direction based on a horizontal correction amount when the correction information comprises a horizontal deviation, and wherein the area is set with respect to the vertical direction based on a vertical correction amount when the correction information comprises a vertical deviation;
• and
• a correction calculation unit that calculates the correction information on a basis of the captured image acquired by the acquisition unit when the correction-time light-shielding range setting unit sets the light-shielding range in the irradiation unit, wherein the correction information is calculated based on a deviation between a center position of the captured image of the imaging unit and a center position of the irradiation range of the irradiation unit, and wherein the deviation is at least one of the horizontal deviation or the vertical deviation.
