Abstract: A vehicle camera device is suitable to be provided in a first vehicle. The vehicle camera device receives a distance between the first vehicle and a second vehicle, detects the environment brightness information, and generates an angle value and a power value according to the distance and the environment brightness information, so as to adjust an angle of depression and a power of an infrared illumination module according to the angle value and the power value.

Abstract: A vehicle camera device is suitable to be provided in a first vehicle. The vehicle camera device receives at least one of a vehicle speed value of the first vehicle, a distance value between the first vehicle and a second vehicle, and an afterimage motion amount of an image of the second vehicle, and selects one of a plurality of exposure parameter functions according to at least one of the vehicle speed value of the first vehicle, the distance value and the afterimage motion amount to determine an optimized parameter value.

Abstract: An image processing method based on adjustments performed according to environment includes capturing an environmental parameter of an image, determining a scene mode of the image according to the environmental parameter, estimating a brightness correction parameter of the image according to the scene mode, and performing an image area determination to obtain an image area and an area brightness of the image area, followed by performing brightness correction on the image according to the image area, the area brightness and the brightness correction parameter, so as to ensure image quality. An image processing system based on adjustments performed according to environment is further provided.
