A video signal processing apparatus for processing a video signal containing first and second color difference signals so as to adjust colors of an image represented by the video signal is provided. The video signal processing apparatus comprises a first gain setting section for setting a first gain conversion characteristic relevant to a first saturation indicated by the first color difference signal, a second gain setting section for setting a second gain conversion characteristic relevant to a second saturation indicated by the second color difference signal, a third gain setting section for setting a third gain conversion characteristic relevant to a third saturation indicated by the first and second color difference signals, a first conversion section for converting a gain of the first color difference signal based on a first input value of the first color difference signal, the first gain conversion characteristic, and the third gain conversion characteristic, and a second conversion section for converting a gain of the second color difference signal based on a second input value of the second color difference signal, the second gain conversion characteristic, and the third gain conversion characteristic.
