SATURATION CONTROL FOR HIGH-DYNAMIC RANGE RECONSTRUCTION

A system and method is provided for generating a tone mapping function to reduce dynamic range of a first image to produce a second image. A luma signal and a plurality of chroma components associated with the first and second image are then determined. A gamut color correction is then performed on...

Zusammenfassung:A system and method is provided for generating a tone mapping function to reduce dynamic range of a first image to produce a second image. A luma signal and a plurality of chroma components associated with the first and second image are then determined. A gamut color correction is then performed on the second image using an adaptive function. The adaptive function is generated by comparing said luma signal and at least one chroma component of said first and second image.
