23. A reading machine comprises: a computing device; an image input device coupled to the computing device for capturing images; and a computer program product tangible embodied on a computer readable medium for causing the computing device to examine multiple individual images, the computer program product comprising instructions for causing the computing device to: perform optical character recognition on a pair of captured images to produce recognized text from each of the images; detect text in one of the pair of individual images that is also found in the other one of the pair of images; combine recognized text from each of the images based on the detected common text; analyze the combined text to determine if incomplete text phrases are present in the combined text from the pair of images at edge portions of either of the images, and when incomplete text phrases are present in the combined text from the pair of images. generate commands to signal a user with user-instructions that guide a user to move an image input device that captures the pair of individual images in a direction to capture more of the text, with the user-instructions to guide based at least in part on the detected incomplete text.
