I'd argue that this is a bit too tin foily. But it is possible for camera manufacturers to build the logic into the camera's firmware.
For example, if it detects the infrared signal, it'll just send a blank feed to the phone's OS.
- jhasse 10y agoGood point. But the camera would need a processor then to decrypt the infrared signal, wouldn't it?
- Jonnax 10y agoBut they already have processors. Calculating white balance, compensating for lens characteristics, and converting the raw data into the format wanted by the OS. The GPS receiver handles all the calculations for determining position. Same with the accelerometer, gyroscope and magnetometer.
- jhasse 10y agoOh didn't know that. Could an infrared filter help in that case?
- Jonnax 10y agoIn this case if it used infrared, sure. But you have to remember that humans can't really notice the high frequency changes in light. There's plenty of scope to encode data in visible light. I'm sceptical if this would be implemented it would be quite a negative selling point for mobile phone cameras. And I don't see why mobile phone manufacturers would consider implementing this functionality.
