摘要:
A data processing device first reads directory data provided for each directory by a file management system which manages files using a directory structure. When meta-data to be attached to the directory data is written in proper XML format, the device appends the meta-data to the end of the read directory data, and outputs the entirety of the data obtained thereby as a directory data file. By appending the meta-data to the end of the directory data in this way, meta-data can be registered by directory with respect to existing data managed by the directory, without affecting existing applications.

An image processing method and apparatus for forming a mosaic image by combining a plurality of material images, dividing a first image that is the basis of the mosaic image into a plurality of tile areas, comparing each tile area with each of the material images, selecting a material image that most resembles the tile area in terms of color or luminance and pasting this material image to the tile area, thereby creating a mosaic image.
摘要:
To generating a mosaic image by combining a plurality of material images, an original image is divided into tiles and a material image having a characteristic similar to that of an image in each tile is applied to the tile. If more than one version of image data having different resolutions is provided as the image data for the material image, a low-resolution version of the image data is used to calculate a characteristic quantity of the image. Thus, the amount of time required to generate the mosaic image can be reduced.

An image processing apparatus is composed of an image memory comprising a plurality of memory elements, and a processor unit comprising a plurality of processor elements. By suitably engineering the arrangement of the image memory of memory elements, the arrangement of the processor unit of processor elements and the connections among the memory elements and processor elements, it is possible to realize, through a simple construction, high-speed image processing such as image density conversion, image color conversion, image masking, image spatial filtering, image enlargement, image reduction, image rotation, image compression, image extension and image color correction. Also provided are an image processing apparatus for a color image, composed of a plurality of image memories and a plurality of processor elements, and a generalized, multifunctional data parallel processing apparatus capable of processing a large volume of data at high speed.

Apparatus and method for processing hierarchically-coded image data includes structure and steps for storing hierarchically-coded image data and providing a first image data by decoding the hierarchically-coded image data. The first image data having a first resolution is stored in a display memory. The stored first image data is displayed on a display, and an area within the displayed first image is designated for a second image. The second image data is provided by decoding the hierarchically-coded image data and is representative of an image in the designated area of the first image. The second image data having a second resolution is stored in a portion of the display memory while the memory maintains the first image data stored therein. Finally, the display displays a combined image including the first image having the first resolution and the second image having the second resolution.

摘要:
In the retrieval of images that resemble a target image from a plurality of images, the image feature quantity of the target image is calculated when the target image is specified. The feature quantity is calculated upon removing an unnecessary area from the specified target image, and retrieval of resembling images is performed using the feature quantity that has been calculated. The unnecessary area is determined automatically based upon a change in luminance in directions vertically and horizontally of the periphery of the target image. Thus, the calculation of feature quantities from which unnecessary portions in an image have been eliminated can be executed with ease and more effective retrieval of resembling images can be carried out.

In an image processing apparatus for managing hierarchical encoded image data by using a server/client system, a server machine transmits encoded image data in one layer designated in units of layers from hierarchical encoded image data to a client machine through a network. The client machine receives the encoded image data transmitted in units of layers from the server machine through the network. The received encoded image data in each layer is reconstructed into one hierarchical encoded image data. That is, latest received encoded image data is stored while converting the latest received encoded image data into one hierarchical encoded image data by combining the latest received encoded image data with previously received encoded image data.
摘要:
A moving image processing method and apparatus for efficient access to a large amount of moving image data. By the hierarchical structure of storage media for storing the compressed moving image data, when reproduction of compressed moving image data is displayed, the data can be transferred with an adjustment of the transfer speed to a predetermined display speed of the moving image. More specifically, the compressed moving image data is transferred from a first storage medium having a large capacity and a slow access speed to a second storage medium having a small capacity and a fast access speed and further transferred from the second storage medium to an expander which expands the data and displays the expanded data. The compressed moving image data and the corresponding administrative information are stored separately in different storage media which are accessible independently of each other. However, the moving image data and the administrative information are regarded as one logical file, preventing an access conflict of the moving image data and the administrative information. Thus efficient access and reproduction of moving image data can be performed.
