    摘要: The present invention allows an image to be coded within a target size without necessitating the image to be input again during the coding of the image, with a mode reflecting a user's intention for coding. To solve this problem, input image data is coded at coding unit 102 and stored into first and second memories, respectively. Coding sequence unit 108 monitors the quantity of codes. When a set value is determined to be reached, coding sequence unit 108 makes data in first memory to be discarded and directs coding means to further increase a quantization step, and continues coding. As previous coded data is stored in second memory, the data is re-coded with the same quantization step as that of coding unit 102 after changing of a parameter at re-coding unit 109, and the re-coded data is stored into first and second memory. At this moment, coding unit 102 and re-coding unit 109 perform an operation and coding on quantization error according to a mode of quantization operation designated at mode designation unit 125.

    摘要: An image input through an input unit is compressed by an encoding unit and stored in first and second memories. A first counter counts the data in its code amount. When the amount of encoded data generated reaches a predetermined size, an encoding sequence control unit sets quantization steps in the encoding unit and re-encoding unit to increase compression ratios. The encoding sequence control unit clears the first memory, causes the re-encoding unit to re-encode the encoded data stored in the second memory, and stores the resultant data in the first memory. Since the encoding unit continues encoding data with the set quantization step, the encoded data are stored in the first memory from the start of the image. Subsequently, every time the data amount stored in the first memory reaches a predetermined amount, the quantization step is increased, and the processing is repeated.

    摘要: According to this invention, encoded data of a target data amount is generated by one image input operation while both lossless encoding and lossy encoding are adopted. For this purpose, a first memory stores encoded data of a shorter encode length among encoded data generated by a first encoding unit which performs lossy encoding and encoded data generated by a second encoding unit which performs lossless encoding. A second memory stores encoded data from a second encoding unit. When an encoding sequence control unit determines that the encoded data amount in the first memory has exceeded the target data amount, the encoding sequence control unit discards data in the first memory, sets a quantization parameter for a higher compression ratio for the first encoding unit, and causes the first encoding unit to execute encoding. Encoded data before the encoded data amount is determined to have exceeded the target data amount is re-encoded by a re-encoding unit.

    摘要: Stored digital data is searched for on the basis of an input image, difference information is extracted by comparing the retrieved digital data and the input image, and the difference information is composited to the digital data. Digital data generated by composition is stored. When no digital data is retrieved, the input image is converted into vector data, and the image that has been converted into the vector data is stored as digital data. Obtained region segmentation information and an input image are composited, the composite image is displayed on an operation screen of an MFP, and a rectangular block to be vectorized is designated as a specific region from the displayed region segmentation information. A user designates the specific region by designating rectangular blocks in an image using a pointing device.

    摘要: This invention provides the following environment. That is, an original document file corresponding to a document to be copied is specified from image data of that document to be copied, and a print process is made based on the specified file so as to prevent deterioration of image quality. Also, when a document to be copied is not registered, a registration process is executed to suppress deterioration of image quality in an early stage. Furthermore, since the document is converted into vector data, re-use of such document is facilitated, and deterioration of image quality can be suppressed even when an image process such as enlargement or the like is made. To this end, when an original digital file cannot be specified, an apparatus of this embodiment executes a vectorization process (S54), converts the obtained vector data into a data format that can be re-used by an application (S55), and registers the converted file in a file server (S56). With this registration process, since the location of the file is settled, that location information is composited on an image to be scanned using an identifier such as a two-dimensional barcode or the like (S48), and the composite image can be printed (S49). Even when the printed document is scanned again, a registered digital file can be easily specified.
