Video samples from a camera or cameras of a mobile device are sent as analog levels to a system-on-chip (SoC) or other processor of the device. The analog levels are the analog video samples or be an encoded form of the video samples. The samples are converted to digital and interpolated within the SoC to produce digital RGB samples suitable for display. Or, the analog video samples are interpolated within the SoC using analog processing to produce analog RGB samples. Or, only the G samples are transmitted to the SoC, and processed using analog processing. After processing within the SoC, the samples are sent as analog levels or in encoded form to a corresponding receiver of a display integrated with column drivers. Digital functionality of the DDIC of the display is moved into the SoC or into circuitry separate from, and connected to, the SoC via an MIPI DSI interface.
