Abstract

A video signal has a data location which indicates whether the signal is originally derived from an optical image by a camera source or a telecine. This data is used (140, 136) in a projection display which received an interlaced video signal and which comprises a spatial light modulator (110) in the form of a deformable mirror device (DMD) so as to selectively vary both the interpolation mode and the updating mode used in the DMD. In one interpolation mode, a complete frame of image data is interpolated from one of the interlaced input video fields, so as to reduce motion artefacts (Fig. 12). In one updating mode, (mode B) odd lines are updated at the commencement of one field and even lines are updated at the commencement of the next, and so on (Fig. 9).
