1. An image processing apparatus comprising at least one processor configured to:
acquire, with respect to a pixel of interest, a combination of a plurality of pixel values representing respective ink application amounts of a plurality of color inks including at least one basic color ink and a first fluorescent ink containing a dispersion element having a fluorescent property;
determine whether a total value of the plurality of pixel values is larger than a threshold value;
reduce, in a case where it is determined that the total value is larger than the threshold value, a first pixel value for at least one ink of the at least one basic color ink so an amount by which to reduce a second pixel value for the first fluorescent ink becomes smaller than an amount by which to reduce the first pixel value corresponding to the at least one ink of the at least one basic color ink; and
apply the plurality of color inks to a recording medium so that an image is recorded on the recording medium.
