A digital camera's
sensor,
buffer,
LCD,
autofocus, etc. are controlled by a set of microprocessors which in turn are controlled by "firmware", which is software stored in the Read Only Memory (
1) of the camera. Many cameras allow the firmware to be upgraded (
2) in order to enhance performance and/or add new features. This is done by downloading an installer from the camera manufacturer's website, followed by running it from a computer connected to the camera via a USB cable, or by running the installer from the memory card inside the camera.
