Abstract

PURPOSE:To quickly display a target compressed document picture by registering identification information indicating a compression system corresponding to individual compression documents stored in a storage medium in a prescribed storage area. CONSTITUTION:At the time of retrieving the compressed document picture from an optical disk, the optical disk to be retrieved is specified first, the list of file names inside a specified directory is displayed on the screen of a CRT display device 15 and the target file name is selected. Thereafter, the presence/ absence of the setting of an expander for indicating the compression system to the document picture of the file name is investigated. When the setting of the expander is present, a data expansion rule table on a magnetic disk is referred to from the expander and pertinent rule information is retrieved. Consecutively, pertinent picture data are read out of the optical disk and a picture processing part 27 executes the expansion processing of the picture data corresponding to rules on a picture memory. The expanded picture data are developed in a display memory 25 and displayed at the display device 15.

In an image information processing apparatus for visually displaying, identification information for registering identification information indicating a compression method of the compressed document image in a predetermined storage area in association with each compressed document image stored in the storage medium. When a registration unit, a rule storage unit that stores in advance a plurality of decompression rule information items respectively corresponding to a plurality of types of compression methods in association with the individual identification information items, and a compressed document image to be displayed are selected. Discriminating means for discriminating the identification information associated with the compressed document image with reference to the storage area, and decompression rule information corresponding to the identification information discriminated by the discriminating means. It is characterized in that it is provided with decompression means for decompressing the compressed document image based on the decompression rule information detected by the rule storage means, and display means for visually displaying the document image decompressed by the decompression means. .

[0006]

According to the present invention, the compressed document image to be displayed by registering the identification information indicating the compression method of the compressed document image in a predetermined storage area in association with each compressed document image stored in the storage medium. When is selected, the identification information associated with the selected compressed document image is determined by referring to the storage area. Subsequently, the expansion rule information corresponding to the determined identification information is detected from the rule storage means, the compressed document image is expanded based on this expansion rule information, and the expanded document image is visually displayed. Therefore, according to the present invention,
Displaying a compressed document image can be performed in exactly the same operation procedure as displaying an uncompressed document image, and the burden on the user when referencing a compressed document image can be significantly reduced. .
