A vehicular image pickup device includes an image capturing unit, a fill light unit and a processing unit. The image capturing unit captures a driving image. The fill light unit provides a supplementary light of a fill light intensity. The processing unit retrieves an object image from the driving image and calculates, by conversion, a brightness distribution of a plurality of pixels on a straight line penetrating the object image. The processing unit fine-tunes a shutter speed of the image capturing unit, a gain of the image capturing unit or the fill light intensity of the fill light unit according to a waveform of the brightness distribution.
