Embedded Camera Remote Control

Abstract

Modern digital single-lens reflex cameras allow remote control access via a bidirectional digital interface, as well as a unidirectional remote shutter control interface. Available products use the unidirectional interface that only allows control of autofocus and shutter, while a PC is required to access any of the camera’s settings remotely. This report describes a prototype implementation of an advanced remote control that uses bidirectional digital communication over USB to access and change common settings. The prototype is developed to support Canon DSLRs, and is tested with an EOS 5D mark II camera. Hardware and software have been developed; the hardware is based on a template design. The prototype is implemented on an FPGA development board. A custom input device has been developed as primary input to the remote control prototype.
