Abstract: PURPOSE: A method for enhancing a night time image for a vehicle camera is provided to secure safety driving at night by improving detailed information of image through a retinex algorithm. CONSTITUTION: A method for enhancing a night time image for a vehicle camera includes a brightness conversion unit(20), a noise range judging unit(30), and a video color processing unit(40). The brightness conversion unit converts an RGB(Red, Green, Blue) value of a night time image into the brightness value. The noise range judging unit detects the difference between pixels and determines a noise region and a non-noise region. The image processing unit applies an enhancement algorithm to only non-noise region.
