摘要： To allow for generation of an image in which a false pattern occurring in a red or blue photographic subject having a higher signal value of R and B signals than that of a G signal is reduced.SOLUTION: An imaging processing apparatus calculating a first color signal, includes: means (305) calculating a vertical color difference signal of an input image signal; means (306) calculating the horizontal color difference signal of the input image signal; first filter processing means (310 and 311) performing a filter processing on the vertical color difference signal; second filter processing means (312 and 313) performing the filter processing on the horizontal color difference signal; and means (309) calculating intensity of a second color signal different from the first color signal. The first filter processing means and second filter processing means change characteristics of the filter processing on the basis of a calculation result of the means (309).SELECTED DRAWING: Figure 3 (From JP2019097062 A)
