The present invention relates to a universal device provided with means to be controlled by a control unit which forms part of a projector. The device exhibits different operational characteristics in accordance with different applications imposed on it by the control unit. In conjunction with this control unit, the device can inter alia be used for the automatic adjustment of the projector, more specifically of convergence, geometry, focus, astigmatism, contrast modulation, gamma correction, soft edge and adjacent and overlapping geometry. In addition, the invention relates to methods used to execute each of these automatic adjustments. Furthermore the same universal device can also be used for other applications, such as signal decoding, signal testing and analysis, peak detection, RAM expansion, co-processor, wire-free transmission of information between at least two projectors. |
