There are cases in which an effective search index cannot be provided to an image data only by extracting character codes from a character object in PDL data. An image processing apparatus of the present invention obtains image data by rendering PDL data, and extracts a character object from the image data. The image processing apparatus performs character recognition processing on the extracted character object to obtain character code information, and provides metadata including the character code information to the image data.

In a system that performs object division of a manuscript and adds metadata, a method is provided which can edit the metadata by an intuitive operation when no appropriate metadata is added or when it is desired that the metadata be increased by adding. An image processing device, which divides an manuscript acquired through an input component into a plurality of objects and adds the metadata, has a user interface for editing the metadata of the objects, and switches, after selecting first and second objects, a retouching method of the metadata in accordance with the contents of the respective metadata of the first object and second object.

An input image is segmented into regions based on attributes of the input image. It is determined whether each segmented region is an illustration region. When it is determined that the segmented region is an illustration region, the color of the determined illustration region is compared with that of a region around the illustration region. When these colors coincide with each other as a result of the comparison, attribute information of the illustration region is changed to that of the region around the illustration region. Print data is generated based on the changed attribute information.

The objective of the preset invention is to easily determine an optimal method for the use of transparent toner. In order to resolve this problem, an image forming apparatus according to the present invention includes an addition unit for adding, to each of objects that constitute an original document, information indicating either that transparent toner is to be printed for the entire surface of the original document or that transparent toner is to be printed for only part of the original document, a storage unit for storing the object and a generating unit for generating image data by employing the object stored in the storage unit, wherein, based on the information added to the object that is stored in the storage unit, the generating unit controls a number of pixels used for printing the transparent toner.

An image processing apparatus has a separation unit for separating objects constituting an image input by an image input unit, a setting unit for setting a criterion to determine whether or not a separated object is stored, and a determination unit for determining whether the separated object is stored based on the criterion set by the setting unit. The image processing apparatus also has a unit for displaying the separated object, responding to a user access via an interface unit, when the separated object is determined to be stored by the determination unit and storing the separated object such that the separated object can be reused.

An image processing device includes a dividing unit for dividing objects of an input image, a metadata adding unit for adding metadata to each of the divided objects by performing OCR processing and morpheme analysis, a display unit for displaying at least one of the divided objects and the metadata added to the divided object, and a metadata accuracy determining unit for determining accuracies of the added metadata. The display unit preferentially displays metadata determined as being low in accuracy by the metadata accuracy determining unit.

This invention has as its object to provide an image processing apparatus, which can obviate the need for image re-input, can effectively generate encoded data that falls within a set size, and can minimize deterioration of image quality. To this end, an image processing apparatus according to this invention includes first discrimination unit for discriminating the type of image of each of a plurality of regions, which form image data input, second discrimination unit for discriminating if the image data is inputted by a continuous scan of images, selection unit for selecting an encoding method used in compression of each region on the basis of discrimination results of the first and second discrimination unit, first compression unit for compressing image data of each region using the encoding method selected by the selection unit, and second compression unit for compressing information that pertains to the type of image of each region.

From inputted multilevel image data it is generated, for each pixel, image area information constituted by an image area component indicating whether the pixel exists in a character•line drawing area or halftone area and an image area component indicating whether the pixel is chromatic or achromatic. The information is encoded by a lossless encoding unit on a block basis and stored, and an amount of code is monitored. When the amount of code exceeds a target amount, the lossless encoding unit performs encoding upon changing image area components, of subsequently input image area components, which coincide with a condition. The codes that have already been stored are temporarily decoded by a lossless code re-encoding unit, and the above image area components are changed. The resultant data is then re-encoded and stored.

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.
