摘要： Provided are a projector capable of correcting a polarization state properly and improving image quality, a retardation plate being used in a projector or the like and being capable of correcting a polarization state properly, and a method of placing a retardation plate. A quarter-wave plate (22) is placed between a reflective spatial light modulator (21) and a PBS (20). The quarter-wave plate (22) includes a combination of a first retardation plate (41) and a second retardation plate (42) each producing a different phase difference. The phase differences produced by two retardation plates (41), (42) are set to be suitable amounts of phase difference according to a position state, so in spite of the fact that the quarter-wave plate (22) including the combination of two retardation plates, the quarter-wave plate (22) can correct the polarization state properly with performance equal to or higher than that in the case where the quarter-wave plate includes a single plate.

摘要： Signals are provided which allow colors in a wider color range than predetermined standards, which can be handled by apparatus according to such predetermined standards. A primary color converter converts first color signals having primary color points in a wider color range than the primary color points according to BT.709 into second color signals based on the primary colors according to BT.709. A photoelectric transducer converts the second color signals into third color signals according to photoelectric transducer characteristics defined in a numerical range wider than a range from 0 to 1.0 of color signals corresponding to a luminance signal and color difference signals according to BT.709. A color signal converter converts the third color signals into a luminance signal and color difference signals. A corrector incorporated in the color signal converter corrects the color difference signals into color difference signals.
