Abstract

In various embodiments, a dynamic range converter includes at least one circuit including a logarithm base 2 (log 2) domain circuit that uses piecewise linear interpolation to perform as at least a portion of one of: a linearizer configured to convert nonlinear color space signals to linearized color space signals; a delinearizer configured to convert linear color space signals to nonlinearized color space signals; a chrominance tone mapper for scaling gamut shaped components in accordance with dynamic color transform metadata to generate chrominance mapped components; or a luminance tone mapper for scaling color remapped components in accordance with the dynamic color transform metadata to generate luminance mapped components. Other embodiments are disclosed.
