Apparatus for enhancing low light level image and method thereof

The present invention relates to a low-illuminance image improved apparatus and method for detecting an LED (Light Emitting Diode) of interest (Region Of Interest) by using a sensor in the front image of the vehicle, and a low illuminance to improve the parameters calculated in the region of interest by improving the brightness and color of the image it is based, to provide a low-illuminance image improvement apparatus and method in the brightness and color of an image with no distortion to improve compensation. To this end, the present invention provides a low-illuminance image improvement device, interest for detecting the preceding vehicle in the front image of the vehicle in the region of interest detector; First pre-processing unit for calculating a first parameter based on the detected brightness of the region of interest by detecting the region of interest; The second pre-processing unit for calculating a second parameter based on the distance between the rear lamp in the region of interest detected by the detection region of interest; After the vertical bisecting the region of interest detected by the detection region of interest, the third pre-processor for calculating a third parameter based on the brightness difference between the two areas; Calculation parameters for calculating a final parameter by summing all of the third parameter calculated by the third pre-processing unit and a second parameter calculated by the second pre-processing unit to the first parameter calculated by the first pre-processor unit .; And comprises, based on the corresponding set value is written to the table for each parameter, by retrieving the set value corresponding to the final parameter calculated by the parameter calculation unit parts of the image improvement to improve the image.
