Abstract: 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.

Abstract: A first processed signal is extracted by extracting an input spatial frequency component corresponding to a periodic pattern by performing filtering processing on an image signal. A subject component of an image included in the extracted first processed signal is extracted from the first processed signal. A second processed signal is extracted by subtracting the first processed signal from the image signal and also by adding the extracted subject component to the image signal.

Abstract: A subject component removed signal is obtained from an image signal representing an image by performing, with respect to a first direction and/or a second direction that is different from the first direction, one-dimensional filtering processing using a subject component removal filter that removes a low frequency component including a subject component of the image to roughly remove the subject component. Further, frequency components corresponding to the periodic pattern in the subject component removed signal are detected with respect to both of the first direction and the second direction.

Abstract: A peak position and a peak width of a frequency spectrum corresponding to a periodic pattern are detected by performing, with respect to at least one direction, frequency analysis on an image signal representing an image including the periodic pattern. The passband characteristics of a one-dimensional filter suppressing a spatial frequency component corresponding to the periodic pattern in the image signal are determined based on the detected peak position and the detected peak width.

Abstract: The image processing apparatus and method process image data of an original image by compressing a dynamic range of the original image. The apparatus and method process the image data of the original image by continuous filtering with at least two edge preserving smoothing filters having different characteristics to generate blurred image data which represents a blurred image of the original image, and process the image data of the original image by compressing the dynamic range of the original image based on the blurred image data. The apparatus includes a blurred image generating unit for generating the blurred image data and having the at least two edge preserving smoothing filters, and a processing unit for compressing the dynamic range of the original image.

Abstract: An image trimming device involves: extracting a region of interest from an original image; detecting a set of features for each region of interest; determining whether each region of interest should be placed inside or outside a trimming frame based on the set of features and setting the trimming frame in the image; extracting an image inside the trimming frame; determining a positional relationship between each region of interest and the trimming frame and increasing or decreasing probability of each region of interest to be placed inside the trimming frame depending on if the region has a set of features similar to that of another region of interest previously placed inside the trimming frame or previously placed outside the trimming frame.

Abstract: When image processing is performed on image data representing an image to obtain processed image data, an image processing condition setting unit calculates a recommended correction amount for compressing the dynamic range of the image. Further, a display unit displays information representing the recommended correction amount.

Abstract: A sealing device for a rotary shaft is provided with a spiral member having a determined pitch and a determined thickness on a rotating portion and/or a stationary portion corresponding to the rotating portion. The spiral member may be provided via a shaft sleeve, or may be directly attached on a rotating portion and/or a stationary portion corresponding to the rotating portion. The spiral member may be in advance shaped in a spiral form, or may be a string-like flexible member which may be shaped in a spiral form.
