<P>PROBLEM TO BE SOLVED: To provide a plasma display device for immediately responding to a request to increase density and definition and displaying an image with a stable operation. <P>SOLUTION: An image signal processing part 40 includes a nonvolatile memory 54 storing parameter data used for image signal processing, a master LSI 50 and slave LSI 51 capturing parameter data from the nonvolatile memory 54 and performing image signal processing in parallel using the parameter data. Each of the master LSI 50 and the slave LSI 51 calculates a checksum value of the captured parameter data. A control part 45 compares the checksum value stored in advance and the checksum value calculated in each of the master LSI 50 and the slave LSI 51, and determines an error in the captured data on the basis of the comparison results. <P>COPYRIGHT: (C)2009,JPO&INPIT |
