Problems solved by technology

[0006] However, the conventional example disclosed in the above-mentioned Patent Document 1 uses a water-repellent film (a film with a large water-repellent angle) to prevent water droplets and foreign matter from adhering to the lens surface, so there are the following problems: It cannot cope with foreign matter and water droplets adhering to the surface of the film. If there are traces of foreign matter or water droplets remaining, the film must be replaced

Embodiment Construction

[0020] Embodiments of the present invention will be described below based on the drawings.

[0021] [Description of the first embodiment]

[0022] figure 1 It is a perspective view showing the configuration of the vehicle-mounted camera device according to the first embodiment of the present invention. Such as figure 1 As shown, the vehicle-mounted camera device 100 is installed at an appropriate position behind the vehicle, for example, to photograph vehicles traveling behind or sideways of the vehicle or objects existing in the surroundings. 1 and a lens 1a provided on the camera 1. Then, the surrounding image collected by the lens 1 a is converted into image data, and the converted image data is output to a post-stage image processing device (not shown) through the connection line 2 .

[0023] A water retaining support member 3 is provided below the lens 1a for preventing the water film (liquid film) from falling downward when a water film (liquid film) is formed on t...

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. [0004] Patent Document 1: Japanese Patent Laid-Open No. 2006-96190 Contents of the invention ...
