Unfortunately, images acquired by users from image acquiring devices like cameras could be under-exposed, overexposed, or backlit. These under-exposed, over-exposed, or backlit images are not suitable for recognizing the information contained in the images. In this paper, we propose a new technique which corrects the brightness of already acquired images from image acquiring devices. This technique divides the image area to determine the state of brightness and operates according to the results of the state analysis without any threshold or magic value. It effectively corrects the brightness of under-exposed, overexposed, or backlit images using only image data analysis.
