AM62A3: About RGB value cliped after CCM in tidss

Ding Y

Part Number: AM62A3

Tool/software:

Dear TI experts，

In the CCM of tidss module, if we set the CCM which will cause the RGB value to exceed the range of 0~255, such as -5 or 260. I would like to know in this case the RGB value after CCM will be clipped to 0~255? Or there will be other processing logic?

Hello,

Could you confirm if the query refers to MCU+ SDK or Linux SDK?

Hi，

The CCM I mentioned refers to the CPR function in the Video Port Output of the DSS module. I'm sorry if it bothers you. I think it's part of the Linux SDK. The following picture is the mathematical formula of CPR, please refer to.
