摘要： In a color reproduction device, an input profile that is referenced in converting an input image from an image input device into a device-independent color image is created based on image input device information, shooting- and observation-time lighting data, and subject data, allowing accurate conversion of the input image to the device-independent color image. In reproducing the image by an image output device, the spectral reflectance of the subject itself is calculated from image input device information and shooting-time lighting data, thereby reducing the effect of the shooting-time lighting. The colors of the subject under observation lighting are calculated from observation-time lighting data. A color reproduced image is estimated accurately on the basis of the subject data even if the input image has little information.

摘要： An optical image reconstructing apparatus includes an optical image forming system. A focused surface controller moves the position of an object surface focused by the optical image forming system. An image pickup converts an image of an object formed by the optical image forming system into an electrical signal and outputs the electrical signal as an image signal. An adder adds a plurality of image signals output from the image pickup while the position of the object surface is moved by the focused surface controller. A frequency filtering device performs a frequency filtering operation on an image signal outputted from the adder to produce a filtered image signal. A rotation controller rotates the object or the optical image forming system at a predetermined angular interval around one point on an optical axis of the optical image forming system. An image synthesizing device performs interpolation on a plurality of filtered image signals output from the frequency filtering device while the object or the optical image forming system is rotated at the predetermined angular interval by the rotation controller, to synthesize images in a surface direction parallel to a rotation control surface of the rotation controller, thereby preparing a reconstructed three-dimensional image.

摘要： A process and an apparatus for measuring the biocurrent distribution call for initially assuming a number of multiple currents which is more than the number of isolated currents possibly existing in a living body and calculating the virtual magnetic field created by the assumed currents at actual measuring points. The estimated location and current vectors of said assumed currents are consecutively changed to decrease the difference between said virtual and actual magnetic fields so that the estimated location and current vectors of the assumed currents having the number corresponding to the true isolated currents substantially approximate the true values and the estimates of the other assumed currents approximate zero. This enables the biocurrent distribution to be exactly determined even when the number of isolated currents is not preliminarily known.
