Publication number: 20200084356Abstract: An image monitoring device includes a luminance calculator and a darkness determiner. The luminance calculator calculates a first average luminance value of an illuminated region which is illuminated with a lamp and a second average luminance value of a non-illuminated region which is not illuminated with the lamp. The illuminated region and the non-illuminated region are included in a video signal generated by capturing with a lens. The darkness determiner determines whether or not the video signal is captured in dark by comparing a difference between the first average luminance value and the second average luminance value with a first threshold value.Type: ApplicationFiled: November 14, 2019Publication date: March 12, 2020Inventors: TOMOYUKI TSURUBE, NOBUYUKI HIROSE, KOHEI YAMAGUCHI
