Claim 10:
11. The system of claim 10, wherein the first mapping weight s determined based on:

W1=(P1_max−thr_1)×k_1,

wherein W1 refers to the first mapping weight; P1_max refers to the first block weight of the first image block; thr_1 refers to a fifth threshold; and k_1 refers to a first mapping slope; and
wherein the second mapping weight is determined based on:

W2=(P3×gain_a−thr_2)×k_2,

wherein W2 refers to the second mapping weight; P3 refers to the third block weight of the corresponding second image block; thr_2 refers to a sixth threshold; and k_2 refers to a second mapping slope.
