ABSTRACT:
An image controlling system in which an image to be displayed is controlled by a control device is to be improved in its operating performance. A control device3and a projector2are interconnected over a USB cable5and an RGB cable6to make bi-directional data transmission/reception to display a picture by the projector2on a display screen S. The projector2includes a projection display unit18fed with display data from the control device3to project light to display a picture represented by the display data, a hub11connected to the control device3and to a USB device to make data input/output based on the supplementary information and a display controller19for controlling a picture demonstrated by the projection display unit18based on a display control signal generated by the control device3. The control device includes a connector32, connected to the projector2, and a controller33for outputting the control signal and the display data to have a picture displayed by the projector2.
