In-vehicle camera device

Abstract

An in-vehicle camera device which is mounted on a vehicle and which captures a periphery image collected from a lens (1a), wherein the surface of the lens (a1) has a water-repellent angle that is equal to or smaller than 100 degrees, preferably equal to or smaller than 60 degrees, so that the water attached to the surface turns into a film. As a consequence, the surface of the lens (1a) exhibits higher hydrophilic properties, and when water droplets attach to the film during rainfall, the water droplets spread over the surface of the lens (1a) and form a water film. Thus, it is possible to immediately remove matter such as dirt when matter attaches to the surface of the lens (1a) and it is possible to keep the surface of the lens (1a) constantly clean.

Description

technical field

[0001] The present invention relates to an on-vehicle camera device that is mounted on a vehicle and captures surrounding images. Background technique

[0002] Regarding the on-vehicle camera mounted on the rear of the vehicle to capture surrounding images to monitor vehicles driving behind or on the side of the vehicle or obstacles existing around the vehicle, foreign matter such as mud may adhere to the lens as the imaging surface when there is rainy weather In such a case, the surrounding image cannot be recorded clearly. Therefore, as a technique for preventing foreign matter from adhering to the lens surface, for example, the technique disclosed in Patent Document 1 is known.

[0003] In Patent Document 1, a waterproof film is provided so as to cover the lens surface, thereby preventing water droplets and foreign matter from adhering to the lens surface.
