Abstract
This disclosure relates to a character recognition method and apparatus through which highly accurate character recognition is capable of being executed inexpensively and at high speed. Character recognition is raised in speed by executing segmentation of character images from an input image and character recognition from the segmented character images in parallel by separate processors without use being made of a special communication processor. After the character images have been segmented from the input image, the results of segmentation are evaluated and the character images are segmented further based upon the results of evaluation. Methods of evaluation include a method involving finding a standard character size from characters written in character images segmented initially, and adopting the difference between the standard size and the size of each segmented character image, and a method involving quantifying results of character recognition of character images segmented initially, and evaluating the results of quantification.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
