Latest Patents

One of Hamashima's latest patents involves a method for color modification utilizing two coefficients. This method transforms a pictorial image comprising pixels represented by a combination of density values in respect to first color components (R, G, B) into a pictorial image represented by second color components (C, M, Y). The first color modification method employs an operation expressed as Q = .alpha.P + .beta., where the original density value P is modified using two correction coefficients .alpha. and .beta. that are predetermined. The second color modification method determines density values after transformation through the calculation of a k-th degree masking equation using k-th degree masking coefficients. A color cube is defined concerning the first color components, which is divided into an n number of blocks, with the k-th degree masking coefficients defined for each block. The calculation of the k-th degree masking equation is then performed using these coefficients, which are associated with points indicative of original density values within the color cube.
