A region of interest extracting section automatically extracts regions of interest from within original images by obtaining the degree by which the features of portions within the original images differ from the features of surrounding portions, based on the colors of the original images, brightnesses of the original images, and the orientations of linear components that appear in the original images. A partial image generating section generates partial images by cutting out images of predetermined sizes that include the regions of interest, which are extracted by the region of interest extracting section, from the original images. The generated partial images are displayed.

The image processing method and apparatus calculate and store gradients representing directions and intensities of a pixel of interest and its surrounding pixels from pixel values of the pixel of interest and its surrounding pixels of image composed of the color image signals that are to be subjected to image processing, calculate connectivity of the pixel of interest with its surrounding pixels from the directions of the stored gradients, calculate directivities of respective R, G and B of the pixel of interest by calculating gradients of respective R, G and B channels of the pixel of interest and decide whether the pixel of interest is an edge portion or not from the calculated connectivity and directivities of respective R, G and B to extract the edge portion. As a result, the method and the apparatus can raise extraction precision of the edge portion, accurately perform the edge portion extraction and increase image quality. Moreover, the method and apparatus calculate correction amounts of degree of sharpness enhancement and granularities of a plurality of the specified regions formed by dividing the image data based on the extraction result of the edge portion and correct the image data based on these correction amounts. Accordingly, careful and minute corrections of granularity and degree of sharpness enhancement can be performed on the image recorded in one frame.

In a relief printing plate according to an aspect of the present invention, the relief can be formed to have resistance to pressure applied to the apex thereof thanks to the depth (d) and the ridge tilt angle (x). In particular, the resistance to pressure against a relief serving as a highlight halftone dot can be improved to prevent the relief from falling over by the pressure applied to the apex of the relief. Thereby, the relief serving as a highlight halftone dot can be made not to be dipped in a cell of the ink roller (e.g., anilox roller).
摘要:
According to an aspect of the invention, on the relief printing plate where a relief serving as a halftone dot is formed on a surface of a plate material, an elliptical frustoconical relief is formed as the relief as well as the minor direction of the elliptical frustum matches the printing direction so that the longitudinal section of the relief in the same direction as in the printing direction is smaller than the longitudinal section of the relief in a direction orthogonal to the printing direction. Thereby, the relief having the aforementioned sectional shape has resistance to pressure as a whole of the relief as well as flexibility in the printing direction.
