2:MT6752/MT6732/mt6735/MT6753/MT6735M/MT6735P 请参考如下修改。
FAQ 提供demo code以实现：
(1)，定义指定的CCM参数以固定当前环境的CCM值不变
(2)，CCM 会根据当前环境达到的real ISO动态调整饱和度
(3)，需要注意的是，如果是 MT6735M/MT6735P 的话 ，下面demo code 里面如下部分要做客制化。
需要将chip_sumValue 修改成256 。反之 维持512 即可。

  1. const MINT32 chip_sumValue = 512; // for MT6752/32/35/53
  2. //const MINT32 chip_sumValue = 256; // for MT6735M/MT6735P
