Optical communications for portable electronic devices

An optical data system comprising:

• an optical-communication device comprising:
• a housing having a window;
• a connector;
• an electrical-to-optical circuit to convert electrical data received at the connector to first optical data;
• a first magnet;
• and
• an optical transmitter to transmit the first optical data through the window;
• and
• an electronic device comprising:
• a housing having a window;
• a display on a surface of the electronic device;
• a first camera for use in photography and to receive the first optical data through the window from the optical-communication device when the electronic device is mated to the optical-communication device;
• a digital-signal processor coupled to the first camera to process the first optical data received by the first camera from the optical-communication device, the digital-signal processor to at least partially compensate for artifacts in the received first optical data caused by marring of the window of the electronic device and the window of the optical-communication device;
• and
• a second magnet, wherein the first magnet and the second magnet secure the optical-communication device to the electronic device.
