Abstract
A data input apparatus includes an image pickup with a zooming function, for converting an original image into an electrical signal, an area judger for judging at least a character area from the image taken by the image pickup and a character recognizer for converting the character image, in the character area judged by the area judger, into a character code. A detector detects errors in the character recognition and a controller controls the zooming function of the image pickup according to an output of the detector thereby effecting the character recognition with an enlarged image when errors increase.
