Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to an information processing device that searches for desired image information from a plurality of types of image information, and particularly relates to an information processing device that searches for desired image information from a plurality of types of image information. The present invention relates to an information processing device.

(Prior Art) In recent years, a large number of printed materials consisting of multiple manuscripts, etc. are sequentially read by an image scanner device and stored as image information in a storage device such as an optical disk device, and this stored image information is used as needed. Various information processing apparatuses have been proposed that search according to the information and output it to a printer or display device.

Conventional information processing devices input search information to specify desired image information using a keyboard, select the desired search information from among a large amount of search information stored in a magnetic disk device, and The desired image information registered in the optical disc g device is searched based on the selected search information.

The image information retrieved in this way is transferred from the optical disk device to the G via the interface circuit and buffer memory.
Given to ODEC.

In GODEC, the searched image information is restored by processing such as expansion, and displayed on a display device via a display memory or the like.

Furthermore, conventional information processing devices have a quick search function for quickly performing search processing.

Specifically, in the quick search mode, when desired image information is retrieved from the optical disk device, the retrieved image information is directly output to the display memory without being stored in the buffer 7 memory. The image information stored in the display memory is sequentially displayed on the display device. Therefore, when image information corresponding to a plurality of pages of a document is retrieved in the quick search mode, the image information for each page is sequentially displayed on the display device.

(Problem to be Solved by the Invention) However, in the conventional quick search mode, after all the image information of one page is displayed on the display device, the image information of the next page is displayed on the display device. Search processing sometimes required waiting time.

For example, it may be possible to determine whether or not the desired image information is displayed when 1/4 of one page of image information is displayed.
Even in such a case, the next image information is not displayed until all of the remaining image information is displayed on the display device, leaving room for improvement.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an information processing device that further reduces the time required for search processing.

It is possible to delete 3/4 from the end and output the image information of the remaining 1/4 from the beginning that was not deleted to the display device 77. In the "quick search" mode, 3/4 of the image information for each page read from the optical disk device 33 based on other types of commands input from the keyboard 101 or the like is deleted from the end; Only the remaining 1/4 of the image information from the beginning that has not been deleted can be stored in the display memory 73.

The display device 77 normally uses the display memory 7
The image information stored in 3 is displayed as is. In addition, if image information for each page is entered in the normal "quick search" mode in which no special command is entered, 3/4 of the image information for each page will be deleted from the end, and the rest will be deleted. Only the image information from the top 1/4 that was not displayed is sequentially displayed.

In other words, when the image information is displayed in the 1/4 area from the top of the entire area of the display screen, the display device 77 displays
This is detected and the display of the remaining image information is stopped.

The CODEC 95 is an encoding/decoding circuit unit, and by compressing image information, that is, reducing redundancy, it is possible to reduce the storage area of a storage medium such as an optical disk used at the time of registration. Also C0DEC95
The compressed image information is decompressed, that is, the reduced redundancy is restored to its original value, and the image information is output as the original image information.
