Abstract
In a method and apparatus for processing an image signal, luminance signals are generated for an object pixel and local pixels. A luminance dispersion value is then generated for the object pixel from the luminance signals of the object and local pixels. A control factor is determined from the luminance dispersion value, and at least one image signal of the object pixel is low-pass filtered according to the control factor.
