Description

Ca2In[CA_LITE_NODE]

An array of six values that determine the input saturation level

Value range: [0x0, 0xc0]

Data type: CVI_U8

Ca2Out[CA_LITE_NODE]

An array of six values defining the UV gain for the output. Find the UV gain according to the input saturation, the larger the value, the higher the saturation; otherwise, the smaller
