In present situation security and observation applications require various sorts of images as wellsprings of information for comprehension and survey. Image enhancement is technique for put on balanced adjustments to an information image to make the following image logically appealing or to pass on an improved redesign age for best in class motorized image getting ready systems. Image enhancement of any underexposed or overexposed image are pressing to bring the information as evacuating information is extraordinarily inconvenient and every so often this information is completely lost. The enthusiasm of overexposed and underexposed images might be irksome or to a great extent, it may be hard to collect such images for indistinguishable packaging. In this exploration, an estimation has been proposed which uses either overexposed image or underexposed image and still improves the idea of the image. Figuring Entropy, and histogram have been broke down which demonstrates the adequacy of proposed calculation. will wear down spatial region undertaking and frequency space movement too. This proposition outlines and thinks about the proposed changes tanlog revision, histogram leveling, gamma adjustment and homomorphism sifting calculation to different underexposed and over uncovered images. Figure of benefits, for example, PSNR.
