A system and method for enhancing the contrast within an image. An
enhanced image can be generated in a real-time or substantially real-time
manner from an initial image. A low-contrast image is enhanced, including
the visibility of text within the low-contrast image. A logarithm
transform method is used to enhance the overall contrast and visibility
within the image. A power transform method is used to enhance the
visibility and contrast of written text, symbols and other forms of signs
within the enhanced image.
