発明の名称 (英語) EDGE-INDUCED ILLUSION GENERATION DEVICE, EDGE-INDUCED ILLUSION GENERATION METHOD, EDGE-INDUCED ILLUSION GENERATION PROGRAM, PRINTING MEDIUM, AND RECORDING MEDIUM
発明の概要(英語) The present invention addresses the problem of providing an edge-induced illusion generation device, an edge-induced illusion generation method, an edge-induced illusion generation program, a printing medium, a recording medium, etc., that can be applied to a given image, is able to automatically generate an edge-induced illusion without requiring complicated tasks, and enables achieving contrast improvement by taking advantage of an edge-induced illusion. The present invention is characterized by generating an edge-induced illusion image by applying, to image data, a two-dimensional digital filter which is a non-oriented filter or an oriented coupled filer, and which is at the same time a filter capable of transmitting a band of relatively high frequencies or a high-frequency pass filter, or an orientation selective wavelet frame or an orientation selective filter bank that is an assembly made up of a non-oriented approximate filter and a plurality of oriented precision filters, so as to extract a band component of relatively high frequencies or a high frequency component and/or to apply color to an edge of the extracted band component or high frequency component.
従来技術、競合技術の概要(英語) BACKGROUND ART
Conventional, the brightness and colour of the edge of a region having a luminance different from the actual visible illusion has been found.
For example, conventional, crake, o'brien, corn suite effect has been known. In this optical illusion, in practice the same brightness at the boundary of an area, the gradation abruptly changes to a gentle variation portion between such as by providing the edge, the brightness of the regions on both sides of the edge appear different. Here, the table below, crake, o'brien, corn suite change in the luminance of an image diagram indicating the effect, the solid line, and the actual brightness, perceived brightness is shown by a broken line. In this way, crake, o'brien, corn suite effect, edge defined by the two adjacent regions 2 in the same brightness, from one area to the edge of the sharp portion of the change in the luminance of the dark smooth, and the other is case of a change in a smooth bright, the brightness of the two regions 2 appear to differ from effect to cause an optical illusion.
TABLE 1
In addition, the prior art, ink painting effect has been known (see Non-Patent Document 2). In effect this ink painting, to practically the same brightness boundary of an area, different from the uniform gray scale in accordance with the present line 2 adjacent to an edge by producing a sudden change, the brightness of the regions on both sides of the edge appear different. The table below, the effect of ink painting an image diagram indicating a change in luminance, the luminance of the rectangular wave 2 of the wavy edge of the mold when forming, a region surrounded by the respective edge, despite the same brightness appears different from each other to cause an optical illusion.
TABLE 2
With respect to color, the conventional, a watercolor illusion has been known (non-patent document 6, see 7). Watercolor illusion is, the actual area enclosed by an optical illusion and appear to have different colors, the color of the bright and dark lines adjacent to the region surrounded by the color of a line color of the inner line may appear as a thin colored. In addition, the shape of the line, the broken straight line is a strong illusion, when the inside of a bright color, the white point is higher when the optical illusion effect has been known. In addition, dots may be the illusion in a dotted line have been reported to occur (non-patent document 6).
In this way, the luminance of the edge of a region having a color, different from the actual visible illusion (hereinafter 'optical illusion due to the edge' is called.) Has been found that several (see Non-Patent Document 1-7).
