Claim 1:
2. The method of claim 1, wherein the acquiring the one or more elements of the equation comprises:
acquiring a first differential value based on a first difference between the maximum luma average value and the minimum luma average value;
acquiring a second differential value based on a second difference between the maximum chroma average value and the minimum chroma average value;
acquiring a first element (α) related to a ratio of the second differential value and the first differential value; and
acquiring a second element (β), based on the first element, the minimum luma average value, and the minimum chroma average value,
wherein acquiring the predicted chroma sample of the current chroma block comprises acquiring the predicted chroma sample of the current chroma block, based on the down-sampled luma sample of the current luma block, the first element (α), and the second element (β).
