PROBLEM TO BE SOLVED: To provide a signal processor for PDP(plasma display panel) capable of reducing the occurrence frequency of spurious profiles and also capable of reducing the number of subfields. SOLUTION: This processor is provided with a first means which calculates the number of pixels having the possibility that spurious profiles are to be occurred as the number of pixels in which the occurrence of the spurious profiles are predicted when a signal level is assumed to be converted by respective signal level converting equations for every predetermined plural kinds of signal level converting equations, a second means which selects a signal level converting equation in which the number of pixels in which the occurrence of the spurious profiles are predicted is the least and a third means which converts the signal level based on the selected signal level converting equation. |
