A real-time image defogging apparatus and method

The present invention relates to an image defogging apparatus and method, in particular one for an image at low contrast defogging conditions of fog or haze conditions to haze, real-time image enhancing apparatus and method of enhancing details. The present invention includes a decoder for decoding a video signal, converts it into a sequence of images; the FPGA, the image enhancement processing sequence fast Retinex algorithm; memory for storing the sequence of images; encoder, the enhancement processing the sequence of images into a video signal. The present invention does not require expensive computational resources and a large data storage capacity, to meet the fog, haze effect to enhance the video image detail fog, haze and other conditions of the day, to enhance the visual quality of the image, while satisfying real-time processing requires hardware, The initial delay is less than 40ms, without affecting the original video frame.
