摘要： PROBLEM TO BE SOLVED: To improve the color reproducibility of image by exchanging color information so as not to make the impression of entire image by different by dividing a color space, which is formed by chrominance signal data for each transmission device and each reception device, into plural color categories while collecting colors sensed by an observer, and exchanging the color information between the same categories. SOLUTION: A transmission color vector C on a CRT display is expressed by C=[γgb] (101) and concerning the color category to which that vector belongs, a color category Q applying a minimum value among 11 pieces of maha;lnobis' distances D is detected (102). Since this color category Q becomes the color category to which the transmission color vector belongs, a color data group Qm' (103) classified into the color category on the liquid crystal display becomes a mapping point candidate. Then, these color candidate color vectors Q' (105) form a color data group, in which the mahalaobis distance of color category is made minimum among all the light-emitting colors on the liquid crystal display.

摘要： PROBLEM TO BE SOLVED: To provide a color conversion table preparing method and a color conversion method capable of easily preparing a color conversion table fit for a color conversion purpose in each color area and synthesizing color areas so that colors are continued in an image area overlapped to plural color areas. SOLUTION: A matrix preparation part A211 prepares a color conversion matrix for all areas form read color chip data and input color chip data and a color conversion table operation part A221 prepares a total color conversion table Ta. A data selection part 203 selects reading color chip data and input color chip data in each color area and a matrix preparation part B212 prepares a selected color conversion matrix for selected data and a color conversion table operation part B222 prepares a selected color conversion table Tb. A color conversion table synthesis part 206 synthesizes both the tables Ta, Tb based on a contribution ratio to prepare a synthetic color conversion table Tc.

摘要： PURPOSE:To enable measurement of a distance at a high speed and with high precision by enabling modulation of a laser light by a plurality of modulation frequencies, by conducting primary measurement of a long distance by a low modulation frequency and by conducting highly-precise distance measurement by a high modulation frequency. CONSTITUTION:A laser light emitted from a laser oscillator 1 is modulated in intensity by a light modulator 2. In order to conduct modulation by a plurality of frequencies, two light-modulating elements 202 and 203 are provided. A distance range for measure ment is divided in a plurality and a long distance is measured primarily at a low modulation frequency, while the range of a relatively short distance is measured with high precision at a high modulation frequency. By combining these two measurements, it is made possible to measure the long distance with high precision. By raising the ratio of the modulation frequencies to (n)th power of 2, in addition, a value of the distance measured by the low modulation frequency is recorded in upper bits, while a value of the distance measured by the high modulation frequency is recorded in lower bits, and they are read out as continuous data, whereby distance measurement of a wide dynamic range is conducted. As the result, high-speed and highly-precise measurement of distances can be realized.

摘要： PROBLEM TO BE SOLVED: To suppress the increase of multiplication frequency of the multidimensional interpolation, to simplify the calculation of a weight coefficient for interpolation and to attain the rational extension up to a multiple dimension by selecting the ridgelines in each axial direction and in the order of larger axial positions against the input point of a unit hypercube and obtaining an interpolation hypercube that is symmetrical to an interpolation operation. SOLUTION: The relation is shown between a unit hypercube and every input axis, and the axes A and B show the 4-dimensional and 5-dimensional axial directions respectively (1). The ridgeline set in the X axis direction, i.e., the maximum direction of sequencing is selected among five ridgelines obtained from the 1st ridgeline extended from an original point 0 of the unit hypercube (2). The ridgeline of the Y direction, i.e., the 2nd sequencing is selected as the 2nd ridgeline by the ridgeline extended newly from an end point of the 1st ridgeline (3). Thus, the ridgelines are successively selected, and the 5th ridgeline is selected in the B direction as the final ridgeline. Finally, a hypercube that is surrounded by six apexes of end points of six segments connecting the end point of the 5th ridgeline and the point O of the unit hypercube is selected as an interpolation hypercube (6).

摘要： PURPOSE:To suppress the deterioration of a picture, and to improve picture quality by obtaining the center of sway, and re-arranging a swaying partial picture or a swaying picture element at this center of the sway. CONSTITUTION:Provided that a measuring sampling interval is sufficiently shorter than the cycle of the sway, the center 10 of the sway can be well approximated by using the center of the motion 9 of a very small part 8 with time, and by shifting the very small part 8 on the picture gr to its center 10 of the sway, the sway can be corrected. By executing this processing for the very small parts enough to fill up the picture gr, the sway of the whole picture gr can be reduced.
