Apparatus for Estimating Airlight of Reducing Computational Burden of Dehazing in Unit Image and Driving Method Thereof

摘要

The present invention relates to an atmospheric intensity estimating device that reduces the amount of fog removal calculation for a single image, and a driving method for the device. The atmospheric intensity estimating device for reducing the amount of calculation for removing fog from a single image according to an embodiment of the present invention includes: An image receiver that receives a single image of red (R), green (G), and blue (B) included, and a plurality of patches having a preset size are applied to the received single image for each line. An image that calculates the average brightness value in the patch area, estimates the atmospheric intensity candidate by comparing the maximum value of the calculated average brightness value between rows, and extracts the atmospheric intensity of a single image by comparing the maximum value of the average brightness value up to the last row. It includes a processing unit.
