An apparatus and method for recognizing characters in image information includes inputting image coordinate data corresponding to the handwritten image, displaying a calligraphic image on the basis of the image coordinate data, recognizing characters in the image coordinate data, and erasing the calligraphic image and displaying recognized characters recognized in the recognizing step in the event that a recognized character is a predetermined character such as a period ('.').

Apparatus and method for recognizing characters

An optical recording medium comprising a substrate and a thin organic film containing at least one kind of dye selected from polymethine family dyes, perylium family dyes, and cyanine family dyes, and a recording process comprising scanning the optical recording medium with a high intensity light beam such as a laser beam to form optically detectable pits on the recording medium.
