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.

Claim (Index 12):
A vehicular image pickup device, comprising:\n an image capturing unit for capturing a driving image; a fill light unit for providing a fill light; and a processing unit for obtaining a grayscale quantity distribution of a plurality of pixels of the driving image on a plurality of grayscale levels, numbering the pixels sequentially in a direction from a highest grayscale level to a lowest grayscale level among the grayscale levels according to the grayscale quantity distribution until the numbering reaches a predetermined number, and adjusting 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 wherein the qrayscale levels are divided into a first grayscale section, a second grayscale section, a third qrayscale section and a fourth grayscale section sequentially in the direction from the highest qrayscale level to the lowest qrayscale level, allowing the processing unit to decrease the fill light intensity or the gain if the grayscale level associated with the pixel numbered with the predetermined number falls inside the first grayscale section, not to adjust the fill light intensity or the gain if the grayscale level associated with the pixel numbered with the predetermined number falls inside the second qrayscale section or the fourth grayscale section, and to increase the fill light intensity or the gain if the grayscale level associated with the pixel numbered with the predetermined number falls inside the third grayscale section.
