Abstract:
1. An image signal processor comprising: a pattern generating unit which generates an illuminating pattern of subfields that constitute one frame of a received image signal to produce a given graylevel, in which a non-illuminating subfield never exists between a first illuminating subfield and a second illuminating subfield; and a pattern moving unit which moves the illuminating pattern and outputs the moved illuminating pattern, wherein all subfields existing between the first illuminating subfield and the second illuminating subfield are selectively illuminated for a plurality of frames such that an average level of illumination for one of the plurality of frames corresponds to the given graylevel; and wherein the first illuminating subfield is a beginning subfield of the one frame, and the second illuminating subfield is a subfield of a frame that has a maximum brightness.
