摘要： PROBLEM TO BE SOLVED: To quickly change the magnification of a multivalue image while holding its high quality. SOLUTION: In the case of changing the magnification of a multi-valued image, a binary image preparing part 31 prepares a binary image set up by using each density level as a threshold from the multi-valued image. The contour of the prepared binary image becomes an equal density line in the density gradient of the original multi-valued image. Therefore, an outline variable magnification part 32 extracts the outline vectors of each binary image and applied magnification change/smoothing to the vectors. Since the obtained outlines of respective binary images express equal density lines in the density gradient of the variable magnification multi-valued image, picture elements having the threshold used at the time of generating each binary image as density are written in the multi-valved image area corresponding to the black picture elements of each binary image. The writing processing is applied to all corresponding binary images in order from a binary image with low density up to a binary image with high density and a multi-valued image reproducing part 33 generates a multi- valued image. Processing for smoothing the density gradient of the obtained multi- valued image is executed and a variable magnification multi-valued image is obtained.

摘要： PURPOSE:To display pictures accompanying the movement of the view point of an observer. CONSTITUTION:For the pictures inputted from cameras 20-23 provided with the different view points, corresponding points in the respective pictures are detected by straight line detection on an epipolar plane by a CPU 25. When the corresponding points are detected, the point provided on a straight line connecting the corresponding points is defined as the position of a picture element constituting the picture for interpolating the picture from the view point of the camera and the value is defined as the picture element value of the corresponding points. By performing this operation for the entire pictures, the pictures from the view point present on the line connecting the cameras are continuously generated. Further, by detecting the view point of the observer generated and displayed at a display, the pictures matched with the view point of the observer are displayed.

摘要： PROBLEM TO BE SOLVED: To provide an image processor for efficiently performing an image processing such as a dynamic range changing. SOLUTION: A first image processing means 112 performs image processing (an informal image processing for generating an image for display with a first processing load (the dynamic range change processing which comprises a smoothing processing, etc.)), to an object image (a radiation image). A display means 115 displays the image after processing in the first image processing means 112. A second image processing means 113 performs image processing with a second processing load (a formal image processing, etc.), to the object image when a user decides and inputs by the display image in the display means 115.

摘要： PROBLEM TO BE SOLVED: To prepare blurred images at a high speed in the case of preparing the blurred images of a large blur amount by performing a blurring processing by reduced images obtained by reducing the number pixels of input image and turning the blurred reduced images to an original number of pixels. SOLUTION: Images are inputted in an image input process P0, a reduction rate is obtained from a blur amount inputted in a blur amount input process P1 and the blur amount is decided based on the blur amount from the input process P1 and the reduction rate from a reduction rate decision process P2 in a reduced image blur amount decision process P. Then, the input images are reduced based on the reduction rate decided in the image reduction rate decision process P2 in an image reduction process P4 and the reduced blurred images are prepared in a reduced image blurring process P5 from the reduced images reduced in the image reduction process P4 by the reduced image blur amount. Then, the reduced blurred images prepared in the reduced image blurring process P5 are magnified to the same size as the input images in an image magnification process P6 and magnified blurred images are outputted.

摘要： PROBLEM TO BE SOLVED: To accelerate processing by reducing a memory capacity without deteriorating its picture in an image processor extracting a uniform density line shape from a multi-valued image so as to execute variable magnification processing. SOLUTION: A multi-valued image acquired by a multi-valued image acquiring part 101 is divided by each of prescribed number of lines by a multi-valued image dividing part 102 to prepare a stripe image. Then an equi-density line outline smoothing and variable-magnifying part 103 extracts the outline vector of the equi-density line of each stripe image, smooths and variable-magnifies it. A multi-valued image reproducing part 104 reproduces the multi-valued image from the outline vector of each smoothed and variable-magnified stripe image and successively stores each reproduced image (multi-valued image) in an image buffer to form the multi-valued image for the part of one screen.

摘要： PURPOSE:To project images photographed by a plurality of cameras on the same plane and correct images of the cameras to an image on the same plane. CONSTITUTION:A coordinate system of a reference projecting surface is indicated by X and Y, and a coordinate system of an input image is shown by (x) and (y). The input image is converted on the basis of a reference parameter and a camera parameter to be a re-projected image on the reference projecting surface. A target corrected image is an image obtained by cutting an area of nx by ny pixels centering an intersection B of a perpendicular from the center of a lens of an (m)th camera to the reference projecting surface and the reference projecting surface. When the area is cut in this manner, it is possible to obtain an image assumed to have optical axes of tone cameras crossed at right angles to the reference projecting surface and be parallel to each other. Accordingly, if an epipolar plane is formed to interplate the image, corresponding points are aligned on a line on the epipolar plane, thus making it easy to detect the corresponding points.

摘要： PROBLEM TO BE SOLVED: To smooth the equal-density linear shape as expected even in any multi-level image and to provide a magnified result having further higher picture quality. SOLUTION: A multi-level image inverting means S2 investigates the average density of input multi-level images, and when the average density is higher than a prescribed value, the input multi-level image is inverted. Then, the equal- density line is extracted for every density gradation of the multi-level image by an equal-density line outline smoothing/magnifying means S3, and that line is magnified to a designated magnification and smoothed. Based on the equal- density line, the multi-level image is reproduced by a multi-level image reproducing means S4, and the distribution of density is smoothed by a density smoothing means S6. Afterwards, when the multi-level image is inverted, the image is inverted again by a multi-level image reinverting means S7. Thus, since the image having a density higher than a prescribed value is processed after being inverted, the quality of the image can be kept.

摘要： PURPOSE: To suppress jaggy, moire or grating distortion in the case of magnifying a multi-level image. CONSTITUTION: A multi-level image acquisition section 10 obtains a multi-level image. A binary image generating section 11 converts the multi-level image into a binary image corresponding to each gradation. In this case, each gradation of the multi-value image is taken notice of and a gradation value and the picture pixel value are compared and a binary image is generated from the result. A binary image outline smoothing magnification section 12 extracts a contour vector from each binary image and conduct smoothing and magnification processing based on the contour vector to provide each binary image after the magnification. A multi-level image generating section 13 reproduces the multi-level image form the binary image after the magnification corresponding to each gradation.
