Abstract
An image coding device capable of securely controlling a total code amount to a fixed amount in coding image data including a character image region and a natural image region mixed together. The image coding device includes a first circuit for extracting a character image region having a variable size from input image data; a second circuit for controlling a code amount of image data of the character image region; a third circuit for multivaluing image data of the character image region extracted by the first circuit; a fourth circuit for reversible coding image data of the character image region multivalued by the third circuit; a fifth circuit for subtracting the image data of the character image region from the input image data to generate image data of a natural image region; and a sixth circuit for non-reversible coding the image data of the natural image region generated from the fifth circuit; wherein the size of the character image region to be extracted by the first circuit is controlled by the second circuit so that the code amount of the image data of the character image region becomes a first preset target code amount, and the image data of the natural image region is coded by the sixth circuit so that a code amount of the image data of the natural image region becomes a second preset target code amount.

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.
