Vehicle image capturing device and image capturing method

Abstract

The invention relates to an image capturing device for a vehicle and an image capturing method. The image capturing device for the vehicle comprises an image capturing unit, a light supplementing unitand a processing unit, the image acquisition unit is used for acquiring a driving image; the light supplementing unit is used for supplementing light according to the light supplementing intensity; the processing unit is used for taking out the object image from the bicycle image and converting brightness distribution of a plurality of pixels on a straight line penetrating through the object image, and the processing unit finely adjusts the shutter speed of the image acquisition unit, the gain value of the image acquisition unit or the light supplement intensity of the light supplement unit according to the waveform of the brightness distribution; the image capturing method comprises the following steps: capturing a driving image by using an image capturing unit, taking out an object image from a bicycle image, and converting brightness distribution of a plurality of pixels on a straight line passing through the object image, and finely adjusting the shutter speed of the image acquisition unit, the gain value of the image acquisition unit or the light supplement intensity of the light supplement unit according to the waveform of the brightness distribution.

Description

【Technical field】 [0001] The present invention is an image capture technology, in particular a vehicle image capture device and an image capture method. 【Background technique】 [0002] The imaging device has a wide range of uses because it can record images. For example, it can be installed in places that need to be monitored, such as the entrances and exits of buildings, to assist in tracing, evidence storage, and other purposes. [0003] A general imaging device is usually installed at a fixed point and performs image capture within the range of image capture according to a fixed operating mode. However, when the imaging device is installed on a moving object, such as a car body, the image quality captured by the imaging device will be affected by the speed of the moving object and degrade, which will further affect the subsequent image capture. The accuracy of image recognition. 【Content of invention】 [0004] In one embodiment, an image capture method includes using ...
