Problems solved by technology

In JP2009-201756A, in such a case that the imaging unit is blocked by the steering wheel and the driver's face cannot be accurately detected, the reason for the failure of facial information acquisition is notified
However, none of these documents propose a solution to the above-described problem of sensitivity change after turning the steering wheel

Abstract

An occupant monitoring apparatus includes: an imaging unit capturing an image of an occupant; an image processor performing predetermined processing on the image of the occupant captured by the imaging unit; and a sensitivity controller changing imaging sensitivity of the imaging unit. The occupant monitoring apparatus monitors the occupant according to the image of the occupant processed by the image processor. The imaging unit is disposed so as to face the occupant with a steering wheel located therebetween. In a case where the steering wheel is turned, the sensitivity controller maintains the current imaging sensitivity without changing the imaging sensitivity.

Description

technical field [0001] The present invention relates to an occupant monitoring device that captures an image of an occupant of a vehicle using an imaging section and monitors the occupant, and in particular, relates to a technique for appropriately adjusting the imaging sensitivity of the imaging section. Background technique [0002] A driver monitor mounted on a vehicle is known as a device that monitors the condition of the occupant. A driver monitor is a device that analyzes the image of the driver's face captured by an imaging unit (camera) and monitors the presence or absence of drowsiness and inattentive driving while driving based on eyelid closure degree, gaze direction, etc. Generally, the imaging unit of the driver monitor includes an imaging element that captures an image of the driver's face and a light emitting element that emits light toward the driver's face. An example of such a driver monitor is disclosed in JP2010-50535A. [0003] In many cases, an imagi...
