IMAGE SIGNAL PROCESSING METHOD AND DEVICE

摘要

The purpose of the present invention is to provide high-quality images in which color shift and noise have been minimized. As a means of achieving this purpose, an image signal processing device, which converts a first image signal to a second image signal, is provided with: a luminance/color difference separation unit that separates or generates a first luminance signal and a first color difference signal from the first image signal; a luminance signal processing unit that converts the first luminance signal to a second luminance signal using a first spatial filter; a color difference signal processing unit that converts the first color difference signal into a second color difference signal using a second spatial filter which differs from the first spatial filter; and a luminance/color difference signal joining unit that outputs the second image signal from the second luminance signal and the second color difference signal.
