Abstract
A vehicular image pickup device includes an image capturing unit, a fill light unit and a processing unit. The image capturing unit captures driving images. The fill light unit provides a fill light. The processing unit obtains a grayscale quantity distribution of pixels of the driving images on a plurality of grayscale levels. The processing unit numbers the pixels sequentially in the direction from the highest grayscale level to the lowest grayscale level according to the grayscale quantity distribution until the numbering reaches a predetermined number. The processing unit adjusts a fill light intensity of the fill light unit or a gain of the image capturing unit according to the grayscale level of the pixel whose number is the predetermined number.
