An original image of text is captured in a low-light environment using a camera on a mobile device, whereby the imaged text comprising images of characters. A brightness setting and a contrast setting of the original image are adjusted to increase the contrast of the imaged text relative to a background of the original image. Optical character recognition is applied to the adjusted image to generate computer readable text or characters corresponding to each of the imaged text. The original image of text is displayed on the mobile device. The computer readable text is also displayed, overlaid the original image, wherein the computer readable text is aligned with the corresponding imaged text.
