Vehicle-mounted optical device and vehicle-mounted optical system

A vehicle-mounted optical device comprising:

• an imaging unit that captures an outside of a vehicle through glass mounted to the vehicle to obtain an image;
• a condensation detection unit that detects condensation of the glass by determining whether an image in a predetermined range of a part of the image is in a predetermined state;
• a condensation removal device control processing unit that actuates a condensation removal device which removes condensation of the glass when the condensation detection unit detects the condensation;
• and
• an image recognition processing unit that performs a predetermined process of exerting influence on a travel control system of the vehicle using an image specified in a predetermined position and range out of the image captured by the imaging unit,
• wherein the imaging unit captures the image having a parallax,
• the image recognition processing unit performs a process of determining a distance to an obstacle included in the image having the parallax, and
• the condensation detection unit detects condensation with another range excluding an image in a range used in the process of determining the distance by the image recognition processing unit out of the image having the parallax as the predetermined range of the part,
• an irradiation unit that irradiates the vehicle glass corresponding to the predetermined range of the part of the image with light having a predetermined frequency, and
• wherein the condensation detection unit uses an image obtained by capturing a moisture sensitive member in contact with a predetermined position of an inner side of the vehicle of the vehicle glass as the image in the predetermined range of the part.
