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.

Signal processing apparatus and method, and program

A three-dimensional image pickup apparatus, a three-dimensional display apparatus and a three-dimensional image pickup and display apparatus are disclosed by which high-definition three-dimensional display from a plurality of eye points of different directions can be achieved by a simple apparatus configuration. The incoming directions and the intensities of a plurality of lights incoming from different directions to a light reception section are coordinated with each other for individual pixels to form video signals. A light emission section emits lights based on a coordinated relationship between the outgoing directions and the intensities of lights to be emitted therefrom for the individual pixels. The light incoming directions and the light outgoing directions are time-divisionally selected by means of light path selection elements, and a plurality of pixels are formed to pick up and display images having a parallax.

A projection screen comprises a red-reflecting particle layer, green-reflecting particle layer and blue-reflecting particle layer sequentially stacked on a substrate. In each particle layer, particles are accumulated by eleven cycles in a regularly alignment such as close packed structure. Diameter of red reflecting particles is approximately 280 nm, diameter of green-reflecting particles is approximately 235 nm, and diameter of blue-reflecting particles is approximately 212 nm. Each particles layer is accumulated by self-organized technique. The substrate used here can absorb light of wavelengths other than those of red, green and blue three primary colors.

Such a structure is to be provided in that in the case where a material, such as a protective film, is coated on a fine particle accumulated layer, such as a photonic crystal, penetration of the material into gaps among the fine particles is suppressed, whereby the mechanical strength against bending stress and tensile stress is improved, and peeling and breakage of the fine particle accumulated layer are suppressed, without adverse affect on the optical characteristics, such as reflection characteristics. The fine particle structure contains a visible light absorbing material absorbing visible light as a substrate, having accumulated thereon in this order silica fine particles having a particle diameter of 290 nm as a fine particle layer for reflecting red light, silica fine particles having a particle diameter of 240 nm as a fine particle layer for reflecting green light, and silica fine particles having a particle diameter of 210 nm as a fine particle layer for reflecting blue light, and further provided thereon a polymer layer or a gelatin layer containing a polymer having a size larger than the gaps among the fine particles. The optical medium, such as a reflective type screen, further contains a diffusion film on the polymer layer or the gelatin layer.

The printed matter for regenerating a three-dimensional image derived from a parallax image string obtained on interpolating shape changes between images constituting the parallax image string is to be produced. An image printing device morphs images constituting a plurality of sets of parallax image strings of an object obtained on photographing by an image pickup device . Based on the morphed parallax image string, the printed matter regenerating a three-dimensional image is formulated by the printer . The image printing device executes processing in which the morphing rate of change is changed depending on the actuation of the actuating unit to display the resulting image on the display unit . The image printing device also morphs the image of the object photographed by the image pickup device with an image stored in the external memory
