Abstract: A vehicular image pickup device includes an image capturing unit and a processing unit. The image capturing unit captures a plurality of driving images sequentially. The driving images each include an object image. The processing unit performs an image analysis on two of the plurality of driving images to obtain a variance of the object image and sets a shutter speed of the image capturing unit according to the variance.

Abstract: 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.

Abstract: A waterproof structure including a housing, a display element assembled to the housing, and a sealing member is provided. The housing has a frame and an opening located on a plane. A portion of the display element is exposed out of the opening. The sealing member disposed between the housing and the display element has a first portion extending toward the opening from the frame and parallel to the plane and a second portion squeezed by the housing and the display element. A first end of the second portion next to the opening leans against the housing, and a second end of the second portion far away from the opening leans against the display element. A gap along a direction between the first portion and the display element is equal to or greater than deformation of the second portion along the direction, wherein the direction is orthogonal to the plane.

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.
