Power supplying and image processing system and operating method thereof

A power supplying and image processing system adapted to a camera comprising:

• a boost converter with a power input port, wherein the boost converter receives an input power through the power input port and converts the input power to output a boosted power;
• an Ethernet power circuit electrically connected to the boost converter and configured to electrically connect to the camera, wherein the Ethernet power circuit is configured to receive the boosted power to output a Direct Current (DC) power to the camera and is configured to forward an image signal captured by the camera;
• a signal-conversion circuit having a first interface and a second interface, wherein a type of the first interface is different from a type of the second interface, the signal-conversion circuit electrically connects to the Ethernet power circuit to receive the image signal through the first interface and converts a format of the image signal;
• and
• a host electrically connected to the signal-conversion circuit through the second interface, wherein the host is configured to obtain a format-converted image signal and perform an artificial intelligence (AI) computation according to the format-converted image signal, the AI computation is configured to generate a control signal, and the host is further configured to selectively send the control signal to at least one of the camera and a display device, wherein the control signal is configured to control an operation of the camera or show an image corresponding to the format-converted image signal on the display device;
• wherein the signal-conversion circuit is further configured to receive the control signal through the second interface and send the control signal to the Ethernet power circuit through the first interface, and the Ethernet power circuit is further configured to forward the control signal to the camera.
