The present invention addresses the problem of providing a darkness determination device, a darkness determination method, and a computer-readable storage medium capable of determining a predetermined entry into a darkness before entering the darkness. The dark place determination device includes: an acquisition unit that acquires a composite image in which a first captured image captured in front of a vehicle at a first sensitivity and a second captured image captured in front of the vehicle at a second sensitivity lower than the first sensitivity are combined; a dark place degree calculation unit; time for calculating the ratio of the number of first pixels of the first captured image included in a predetermined determination region or the number of second pixels of the second captured image included in the determination region to the number of determination pixels included in the determination region of the composite image the variable quantity is used as a dark place proceeding degree; and a determination unit that determines that it is scheduled to enter a dark place when the degree of progress in the dark place is equal to or greater than a predetermined threshold value.
本发明的课题在于提供可在进入暗处之前判定预定进入暗处的暗处判定装置、暗处判定方法及计算机可读存储介质。暗处判定装置包括:获取部,获取将以第一灵敏度拍摄到车辆前方的第一拍摄图像与以比所述第一灵敏度低的第二灵敏度拍摄到所述车辆前方的第二拍摄图像合成后的合成图像;暗处进行度算出部,算出预先规定的判定区域中所含的所述第一拍摄图像的第一像素的第一像素数或所述判定区域中所含的所述第二拍摄图像的第二像素的第二像素数相对于所述合成图像的所述判定区域中所含的判定像素的像素数而言的比例的时间变化量作为暗处进行度;以及判定部,在所述暗处进行度为预先规定的阈值以上的情况下,判定为预定进入暗处。
