A computer-implementable method of adjusting a control parameter of an image capture device includes detecting, determining, and transmitting. At an interactive display device, a substantially continuous user selection of values of a control parameter of the image capture device is detected from user manipulation of a continuously-variable input control of the interactive display device. A rate of change is determined of the user selected values of the control parameter during user manipulation of the continuously-variable input control. Based upon at least the determined rate of change, it is determined whether to transmit each of the selected values. The selected values are sequentially transmitted to the image capture device, via a communications network, where the selected values are determined to be transmitted. Each of the transmitted values is transmitted as an interim control parameter value, and the transmitted values are adapted to adjust the control parameter of the image capture device.
