Video processing apparatus and method of operating the same

A video processing apparatus, comprising:

• an image sensor configured to acquire a video signal;
• a main board comprising a main computing device configured to transmit video data generated based on the video signal;
• and
• a connector board connected to the main board via a communication interface and comprising a socket on which a modular computing device is removably mounted, the modular computing device being configured to process the video data received from the main board via the communication interface,
• wherein the connector board comprises:
• a power control logic configured to, in response to a control signal received from the main board via the communication interface, control power supplied through the socket to the modular computing device, independently of power supplied to the main board;
• and
• a mode setting logic configured to, in response to the control signal, set an operation mode of the modular computing device selectively to a firmware update mode or a normal operation mode, and
• wherein, in the firmware update mode, the connector board is configured to update a firmware of the modular computing device without physically separating the modular computing device from the socket, while the power supplied to the main board is maintained and the connector board is operable.

A method of operating a video processing apparatus, the method comprising:

• processing, by a first circuit portion, video data received from an image sensor;
• generating, by a first computing device of the first circuit portion, a control signal;
• controlling, by a power supply control circuit of a second circuit portion in response to the control signal, power supplied to a second computing device mounted on an interface of the second circuit portion;
• setting, by an operation mode setting circuit of the second circuit portion in response to the control signal, an operation mode of the second computing device selectively to a normal operation mode or a firmware update mode;
• and
• updating, by the first computing device in the firmware update mode, a firmware of the second computing device while power to the first circuit portion is maintained and a second circuit portion is operable.
