Embodiment Construction

[0043] Detailed description of the preferred embodiment

[0044] Referring now to the drawings, various embodiments of the present invention will be described in detail.

[0045] FIG. 1 is a block diagram for showing an image processing system (hereinafter, simply referred to as "system") in which an image processing apparatus according to the present invention is installed. The system 1 includes an image input terminal 3 , an image processing device 5 and an image output terminal 7 .

[0046] The image input terminal 3 may include any number of image sources for performing processing operations to form a digital document (hereinafter will be simply referred to as "document") DOC and to edit the document DOC, such as a personal computer 31, a color scanner 32, a digital camera 33 and a storage medium such as a hard disk unit. For example, the image input terminal 3 may be a terminal device having a communication function capable of acquiring images through a communication ne...

Abstract

A domain block extracting unit extracts a domain block image from an original image. A range block extracting unit extracts a range block image from an area in the vicinity of the domain block image. The range block image has size being larger than a domain size and being smaller than an enlarged size. A reduced range block forming unit reduces the range block image to the domain size to produce a reduced range block image. A similarity judging unit compares each of the reduced range block images with the domain block image to select the highest similarity range block image. An enlarged range block forming unit forms an enlarged range block image by enlarging the size of the highest similarity range block image to an enlarged size thereof. An enlarged image acquiring unit produces an enlarged image of an original image by employing the respective enlarged range block images.

Description

technical field [0001] The present invention relates to an image processing apparatus for enlarging an image expressed in a multi-gradation manner, and to a program for performing image enlarging processing operations using a computer. Background technique [0002] One of signal processing operations for digital images is an enlargement processing operation. For example, various image processing functions with high image quality are required in both the database field and the high-precision color printing field. Among these image processing functions, an image enlargement function is required. Image enlargement processing operations may constitute one of the basic processing operations for a system capable of editing, filling, displaying, and printing images. For example, in the case that digital images input from an external source are printed out in an enlarged manner by printers with different resolutions or displayed on a display unit, it is necessary to perform an enl...
