In a signal processing apparatus which can output a chroma signal of m bits into
a chroma signal of n bits via an output apparatus, the chroma signal of m bits
is gamma converted into a chroma signal of k bits, the gamma converted chroma signal
of k bits is converted into a signal of k bits showing a brightness and a color
tone, and the signal converted into the signal of k bits showing the brightness
and color tone is converted into a signal of n bits showing a brightness and a
color tone. Thus, a signal processing apparatus is provided in which color crush
in a high luminance area of an image can be remarkably reduced, and white skip
of the image and discoloration are remarkably improved.
