Reading text in any scene is useful in the context of wearable computing, robotic vision or as an aid for visually handicapped people. Here, we present a novel automatic text reading system using an active camera focused on text regions already located in the scene (using our recent work). A region of text found is analysed to determine the optimal zoom that would foveate onto it. Then a number of images are captured over the text region to reconstruct a high-resolution mosaic of the whole region. This magni ed image of the text is good enough for reading by humans or for recognition by OCR. Even with a low resolution camera we obtained very good results.
