Data communication between capsulated camera and its external environments

A method for transmitting data or command to a camera, comprising:

• using optics of the camera, capturing an image of a predetermined pattern presented in the camera's field of view, wherein the image includes multiple sub-areas which encode a command or data to be communicated to the camera;
• using one or more lighting devices in the camera to provide a parallel data bus;
• decoding the captured image to recover the command or data;
• and
• operating the camera in accordance with the recovered data or in accordance with a result of executing the recovered command.

A method for transmitting data or command to a camera, comprising:

• using optics of the camera, capturing an image of a predetermined pattern presented in the camera's field of view, wherein the image includes multiple sub-areas which encode a command or data to be communicated to the camera;
• using one or more lighting devices in the camera to provide a clock signal;
• decoding the captured image to recover the command or data;
• and
• operating the camera in accordance with the recovered data or in accordance with a result of executing the recovered command.

A method for transmitting data or command to a camera, comprising:

• using optics of the camera, capturing an image sequence presented in the camera's field of view that includes one or more predetermined patterns each of which encodes a command or data to be communicated to the camera based on an amount of change in pixel value in a spatial direction;
• using one or more lighting devices in the camera to provide a parallel data bus;
• decoding the captured image sequence to recover the command or data;
• and
• operating the camera in accordance with the recovered data or in accordance with a result of executing the recovered command.
