Abstract
This vehicle-mounted camera includes a substrate on which an imaging device is mounted, a holder that holds a lens unit, and a bonding portion that is made of an adhesive having photo-curing property and bonds the substrate and the holder to each other in a direction intersecting an imaging surface of the imaging device.
Claims8
A vehicle-mounted camera, comprising:
- a lens unit;
- an imaging device configured to:
- capture an image;
- detect an object based on the captured image;
- and
- control a vehicle based on the detected object:
- a substrate, wherein
- the imaging device is on the substrate, and
- the substrate has a plurality of side surfaces, wherein the plurality of side surfaces includes a first side surface, a second side surface, a third side surface, and a fourth side surface;
- a holder configured to hold the lens unit;
