Claim:
1. A method enhancing a video, the method comprising: accessing a first frame of the video, the first frame including first pixel data, each pixel of the first pixel data having an intensity value within one of a plurality of non-overlapping ranges of intensity values that includes a first range of intensity values and a second range of intensity values; compressing the intensity values of the first pixel data to generate non-linearly compressed (NLC) pixel data such that pixels of the first pixel data that have intensity values within the first range are reassigned to intensity values within a sub-range of the first range, and such that pixels of the first pixel data that have intensity values within the second range are reassigned to intensity values within a sub-range of the second range, wherein the sub-range of the first range includes a different number of intensity values than are included in the sub-range of the second range; upsampling the NLC pixel data based on an upsampling ratio to generate upsampled pixel data; and decompressing the intensity values of the upsampled pixel data by reassigning intensity values of the upsampled pixel data to intensity values in the first range and the second range, to generate decompressed pixel data.
