摘要： It is an object of the present invention to provide signals 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 62 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 63 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 64 converts the third color signals into a luminance signal and color difference signals. A corrector 64A incorporated in the color signal converter corrects the color difference signals into color difference signals in a range from −0.57 to 0.56 containing a range from −0.5 to 0.5 according to BT.709, which color difference signals are assigned to an integral value in a range from 1 to 254 containing a range from 16 to 240 according to BT.709. The present invention is applicable to a video camera, for example.

摘要： Disclosed is a color liquid crystal display (LCD) apparatus employing a transmissive color liquid crystal display panel. The apparatus includes, as a light source, a main white light source (21) having a three wavelength phosphorescent lamp emitting light with three or more wavelengths, and an auxiliary light source (22) having at least one of a red light emitting diode (22R), a green light emitting diode (22G) and a blue light emitting diode (22B). The red light emitting diode emits red light with a peak wavelength λpr=645 nm, the green light emitting diode emits green light with a peak wavelength λpg=555 nm and the blue light emitting diode emits blue light with a peak wavelength λpb=440 nm. The light sources act for completely covering the color reproducing range of the sRGB standard and further enlarging respective color ranges.
