When a user positions a handheld Braille converting device on an object, a CCD camera captures an image of a predetermined range around it. The presence/absence of character(s) is detected based on the captured image. When the characters exist, the characters are recognized, and the recognized characters are converted to Braille and displayed. When the relative position between the moving direction of the handheld Braille converting device and the character string existing in the captured image is not correct, an error is displayed.
