Claim 11:
12. The method of claim 9, wherein determining the parameter of the component linear model according to the filtered maximum first picture component reference value, the maximum to-be-predicted picture component reference value, the filtered minimum first picture component reference value and the minimum to-be-predicted picture component reference value comprises:
the parameter of the component linear model comprises a multiplicative factor and an additive offset;
calculating a first difference value between the maximum to-be-predicted picture component reference value and the minimum to-be-predicted picture component reference value;
calculating a second difference value between the maximum first picture component reference value and the minimum first picture component reference value;
setting the multiplicative factor to be a ratio of the first difference value to the second difference value; and
calculating a first product between the maximum first picture component reference value and the multiplicative factor and setting the additive offset to be a difference value between the maximum to-be-predicted picture component reference value and the first product; or calculating a second product between the minimum first picture component reference value and the multiplicative factor and setting the additive offset to be a difference value between the minimum to-be-predicted picture component reference value and the second product.
