Abstract

[Problem to be Solved]To reduce the influence of ambient light when monitoring a vehicle occupant.[Solution]A vehicle occupant monitoring device 3 includes: an acquisition unit 31 that acquires a near infrared image and a color image in which a vehicle occupant is captured, the color image being an RGB image or a YUV image; a selection unit 32 that, when the color image is an RGB image, converts the RGB image into a YUV image and selects the near infrared image or the YUV image; and a determination unit 33 that determines a state of the occupant using the near infrared image or the YUV image selected by the selection unit.The selection unit divides a region in which the occupant's face is captured in the YUV image into a plurality of subregions, and calculates a mean value of brightness values of pixels included in each of the subregions, selects the near infrared image when the mean value is equal to or greater than a predetermined threshold, and selects the YUV image when the mean value falls below the threshold.
