ABSTRACT:
An apparatus and method for image rendering includes a first buffer operative to receive first video data. A motion mad updater receives video data from the first buffer and updates a motion map using the first video data. A grain information generator is coupled to the first buffer and receives the first video data to generate slope information based on the first video data. A grain information filter receives the slope information and filters the slope information to generate filtered slope information. A spatially interpolated field generator receives the filtered slope information and generates a spatially interpolated field. A maximum difference value generator generates a maximum difference value based on the update motion map. A base value generator receives the first video data and the spatially interpolated field and generates a base value therefrom. A missing video data generator generates missing first video data.
