摘要： In coding through adaptive quantization after transforming an image into frequency areas, such as JPEG, quantization step width control information and other information are efficiently coded. An input image is processed in a blocking circuit and a quantizer. A quantization step width is determined by multiplying a matrix of a basic quantization table by an SF value of a scaling factor calculating circuit. Quantized AC components are coded in an AC component coding circuit 51. Quantized DC components are converted into DC differences and further into group numbers and additional bits. SF values are also converted into SF value differences and further into group numbers and additional bits. The DC components and the group numbers of the SF values are converted into two-dimensional Huffman codes. The above described code elements are multiplexed and outputted.

摘要： An image processing apparatus includes a reception unit, a determination unit, a handwriting separation unit, an image generation unit, an image recognition unit, and an output unit. The reception unit receives handwriting information. The determination unit determines whether first handwriting indicated by first handwriting information and second handwriting indicated by second handwriting information overlap each other on the basis of the handwriting information. The handwriting separation unit separates the first handwriting from the second handwriting by changing a first/second handwriting position in the first/second handwriting information when the determination unit has determined that the first and second handwriting overlap each other. The image generation unit generates an image from handwriting information obtained through the separation, and information regarding handwriting that has been determined not to overlap other handwriting. The image recognition unit recognizes the generated image. The output unit outputs the recognition result.

摘要： A translation device analyses image data that includes characters, to separate and extract a character region, and another region whose structural elements differ from those of the character region; recognizes characters in the region determined to be the character region; extracts a character string related to the other region, from a result of the character recognition, to associate the character string with the character region from which the character string is extracted and the other region; translates the resulting recognized characters; and, based on the association between the character string and the other character region, pastes the resulting translation that includes the character string onto the same page as the other region that is associated with the character string.

摘要： A decoding apparatus includes a classification section, a distribution-information generation section and an inverse-quantization-value generation section. The classification section classifies quantization indices contained in input code data into a plurality of groups. The distribution-information generation section generates distribution information of the quantization indices for each group, based on the quantization indices classified by the classification section. The inverse-quantization-value generation section generates inverse quantization values, which correspond to the respective quantization indices, based on the distribution information generated by the distribution-information generation section.
