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.
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 an image processing method which allows easy re-use of image information that is stored to minimize deterioration of image quality and the storage capacity. Storage means is searched for original digital data corresponding to each input image. If no original digital data is found, the input image is converted into vector data, and is stored as digital data in the storage means. A sheet including at least one of information associated with the found original digital data when the original digital data is found in the search step and information associated with digital data which is obtained by converting the image into the vector data in the vectorization step and is stored in the storage step when no original digital data is found in the search step is generated, thus providing a sheet that allows easy re-use.

An image processing apparatus capable of performing high-quality image reproduction to even low-density and color characters in an original is provided. The character is recognized from an image, the character of the original is expanded into a dot font based on the recognition result, and the image is reproduced. Furthermore, the character density of the original is detected, a character style of the character used in the reproduction image is determined according to the detected character density, a size of the character used in the reproduction image is determined according to the detected character density, and density of the character used in the reproduction image is also determined according to the detected character density. Furthermore, a color of the character of the original is detected, and a color of the character used in the reproduction image is determined according to the detected character color.
摘要:
An image processor includes a first reader which obtains a first signal corresponding to visible information read on an original, and a second reader which obtains a second signal corresponding to invisible information on the original. A comparator compares the first and second signals to discriminate a predetermined pattern on the original.

An image processor which processes an image signal using a DSP (digital signal processor), wherein a shading correction process, a logarithmic transformation process, an edge emphasizing process, a density adjustment process and a binarization process of the like are performed utilizing the DSP and a look-up table outside the DSP. An image signal is input in an order of raster scanning, and each pixel data of the image signal is set to an input register of the DSP. Calculations necessary for shading correction are performed in parallel on the pixel data by a plurality of ALUs in the DSP, and a logarithmic transformation is performed on the calculation results utilizing the look-up table. Further, the logarithmically-transformed signal is input to the DSP and set to the input register for an edge emphasizing process which is performed by the plurality of ALUs. The result is again input to the look-up table for a density adjustment process and input to the DSP for binarization and subsequent output.
