A three-dimensional image display apparatus comprising a display panel, which displays a parallel projection image corresponding to a three-dimensional image, and an array plate disposed on a front of the display panel and having pinholes arranged two-dimensionally. Further, the invention relates to nucleic acid sequences encoding said polypeptide, and to the complements of such nucleic acid sequences. The sent signal may consist of a calibration offset value to correct the indicated temperature in the instrument. In one embodiment, the detectors comprise a PS-IIR filter to split the electrical signal into the subbands.
