Embodiment Construction

[0049] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0050] figure 1 It is a block diagram showing the imaging device 10 of the present invention.

[0051] The imaging device 10 has a plurality of camera units 11A, 11B, 11C, and 11D for imaging the periphery of the vehicle, and the camera units 11A, 11A, and An ECU (Electronic control Unit: electronic control unit) section 12 for controlling the state of contamination of 11B, 11C, and 11D.

[0052] The camera section 11A has: an imaging section 14 composed of an imaging element that converts light passing through a lens into an electrical signal; an imaging element control section 15 that controls the imaging section 14; The video signal processing part 16 that converts the signal output by the part 14 into a video signal; in order to output the video from the video signal processing part 16 to the ECU part 12, the I / F (interface) that connects the video signal proces...

Abstract

Provided is a vehicle-mounted imaging device that can, at a facility, at home, or the vicinity thereof at which a user can easily eliminate contamination of a camera lens or lens protection glass, perform a notification regarding the contamination. The present invention is equipped with: an accretion diagnosis unit (22) that diagnoses the state of contamination accreted to a camera unit (11A, 11B, 11C, 11D) lens or lens protection glass; and a contamination notification determination unit (23) that determines the presence / absence of a contamination notification on the basis of position information of the vehicle and a predetermined type of facility obtained from a navigation device (31) provided with a database (31b) containing a GPS (31a), a map, and nearby facility information. When the degree of contamination has been determined to be at least a threshold by the accretion diagnosis unit (22), a path to a destination is set by the navigation device (31), and a facility is determined by the contamination notification determination unit (23) to be present in a predetermined distance range from the path, the user is notified of the contamination by means of a display device (32) and speaker device (33) provided to the vehicle.

Description

technical field [0001] The present invention relates to a vehicle-mounted imaging device having a function of detecting attachments such as water droplets or stains adhering to the surface of the objective lens of a camera mounted on a mobile body traveling in an outdoor environment or the surface of a protective member for the objective lens, And send a notification to the user of the mobile body. Background technique [0002] Conventionally, a back monitor device (for example, refer to Patent Document 1) is known as a vehicle imaging device equipped with a small camera for checking the periphery of the vehicle, for example. [0003] Since an in-vehicle camera is usually installed outside the vehicle, there are cases where images are blurred due to dirt on the lens surface of the camera or the like. [0004] In order to solve this problem, it is judged based on the image whether the lens in the camera is dirty or not, and if the judgment is "stained", the vehicle is inform...
