How does the dual native ISO technology of DJI Mini 3 work?

DJI Mini 3 features the dual native ISO values of ISO 100 and ISO 800.

Photo mode and video mode (24/25/30fps): The sensor will algorithmically integrate the images gained by the two sets of analog amplifier circuits for a better dynamic range of actual imaging.

Video mode (48/50/60fps): When you set an ISO value below 800, the drone will use the low-gain analog amplifier circuit. When you set an ISO value above or equal to 800, the drone will use the high-gain analog amplifier circuit. When recording with a frame rate of 48/50/60fps, it is recommended to set the ISO value to 100 in strong lighting environments, or 800 in low-lit environments for better imaging effects.
