    Abstract: A solution method for solving an underdetermined system of linear equations, in which the number of elements of a variable to be determined is N and the number of linear equations is M (where M and N are integers satisfying 1?M<N), using iterative calculations, comprises, in each iteration: an extraction step of extracting at least M non-zero element candidates from the N elements of the variable; a subproblem solving step of setting a subproblem having only the extracted non-zero element candidates as a variable, and solving the subproblem as an ill-posed problem; and an updating step of updating values of the N elements of the variable to be determined on the basis of values of the non-zero element candidates obtained in the subproblem solving step.

  • Patent number: 9652687
    Abstract: An image processing apparatus capable of performing development by adjusting the saturation level of each color signal, without losing gradation in a high-luminance area. Saturation levels of color signals of three colors are calculated on photographed data. Color signal values in each pixel of the photographed data are acquired as pixel information. If it is determined, based on the saturation levels and the pixel information, to perform substitution, substitution for a color signal having the second highest saturation level is performed according to a color signal having the highest saturation level, and substitution for a color signal having the lowest saturation level is performed according to the color signals having the highest and second highest saturation levels. Predetermined processing is performed on photographed data on which substitution processing has been performed to thereby generate the developed data.

  • Patent number: 9653249
    Abstract: The present invention relates to a transmission type target having a diamond base material as the transmissive base material. The transmission type target includes a target layer containing a metal carbide constituted of at least one metal selected from the group consisting of molybdenum, tantalum, and tungsten and carbon; and a diamond base material supporting the target layer. The transmission type target inhibits the composition of the target layer from varying with the drive history of the transmission type target and inhibits the output of radiation from varying over a long time.
