摘要： An apparatus for determining the probability that the shadow of a tumor designated on a radiation image of an object is the shadow of a malignant tumor on the basis of an image signal representing the radiation image includes a spectrum calculating means, a characteristic value calculating means, and a judging means. The spectrum calculating means obtains the spectrum distribution of the image signal D(r,.theta.) whose coordinates are expressed in polar form with the origin taken as the approximate center of the shadow. From the spectrum distribution the characteristic value calculating means obtains a characteristic value, which the judging means uses to determine the probability that the shadow of a tumor is the shadow of a malignant tumor.

摘要： Calculations are made to find the differences, .DELTA.ij=fij-f0, between the value of an image signal component f0 representing as picture element P0 in a radiation image and the values of image signal components fij representing the picture elements Pij, which are located on each of a plurality of lines Li, where i=1, 2, . . . , n, extending from the picture element P0 to the peripheral parts of the radiation image, and which are spaced a plurality of distances rij, where j=1, 2, . . . , m, from the picture element P0. A representative value, which is representative of the differences .DELTA.ij, is then found for each of the lines Li. A mean-level value of two representative values for each set of two lines, which extend from the picture element P0 in approximately opposite directions, is then calculated. From the mean-level values, which have been calculated for a plurality of the sets of lines, a judgment is made as to whether the picture element P0 falls or does not fall within the region corresponding to a circular pattern in the radiation image.

摘要： Disclosed is a technique for correcting a pixel defect in the capture of two radiological images with parallax therebetween. Radiation beam is directly radiated to a radiation detector 15 in two radiographing directions, without passing through a subject, thereby acquiring two defect detecting radiological images. A pixel defect in each of the two defect detecting radiological images is detected in advance. A pixel position where the pixel defect occurs is stored in advance so as to be associated with each radiographing direction. Then, radiation beam is radiated to the subject from the two radiographing directions to acquire two radiological images for diagnosis. A target pixel which is disposed at the stored pixel position where the pixel defect occurs in each of the two radiological images for diagnosis is corrected.

摘要： To acquire a high-resolution frame from a plurality of frames sampled from a video image, it is necessary to obtain a high-resolution frame with reduced picture quality degradation regardless of motion of a subject included in the frame. Because of this, between a plurality of contiguous frames FrN and FrN+1, there is estimated a correspondent relationship. Based on the correspondent relationship, the frames FrN+1 and FrN are interposed to obtain first and second interpolated frames FrH1 and FrH2. Based on the correspondent relationship, the coordinates of the frame FrN+1 are transformed, and from a correlation value with the frame FrN, there is obtained a weighting coefficient α(x°, y°) that makes the weight of the first interpolated frame FrH1 greater as a correlation becomes greater. With the weighting coefficient, the first and second interpolated frames are weighted and added to acquire a synthesized frame FrG.

摘要： Processing speed is improved, by decreasing the amount of calculations required in face detecting processes. A human subject is photographed, and light is received by light receiving elements for each color component, to obtain pieces of pixel data. Next, a raw color image is generated from the pixel data, and a green signal image is generated from green pixel data. Thereafter, faces within the raw image are detected, by performing face detecting processes on the green signal image.

摘要： Sharpness is adjusted for more appropriately representing a predetermined structure in an image. A parameter acquisition unit obtains a weighting parameter for a principal component representing a degree of sharpness in a face region detected by a face detection unit as an example of the predetermined structure in the image, by fitting to the face region a mathematical model generated by a statistical method such as AAM based on a plurality of sample images representing human faces in different degrees of sharpness. Based on a value of the parameter, sharpness is adjusted in at least a part of the image. For example, a parameter changing unit changes the value of the parameter to a preset optimal face sharpness value, and an image reconstruction unit reconstructs the image based on the parameter having been changed and outputs the image having been subjected to the sharpness adjustment processing.
