A transmitter that outputs an image signal for displaying a first image and outputs an image signal of a synthesized image made of the reversal image of the first image and a second image. A display apparatus, based on the image signals output from the transmitter, displays the first image and the synthesized image with circular polarizations having different senses of rotation from each other. A receiver includes a circular polarization selecting and transmitting means that separates the first image and the synthesized image displayed on the display apparatus, based on the sense of rotation of the circular polarization, and selectively allows the images to pass therethrough, so as to be able to photograph the first image displayed on the display apparatus.

A light control film including transparent layers and light absorbing layers arranged alternately is provided. The film is capable of controlling emission angle of light from the light source relatively strictly, and the light use efficiency thereof is improved. Further, a lighting device and a display device using thereof are provided. A transparent layer includes a high refractive index area and a low refractive index area, and further, a light reflective layer is provided at least on the light incident surface of the light absorbing layer out of the light absorbing layer and the low refractive index area. Thereby, a light control film having high light use efficiency is realized by utilizing reflection on the refractive index interface. At the same time, a lighting device capable of switching lighting angles and a display device capable of switching view angles, incorporating the control film, are realized.

An image processing apparatus sequentially provides a display device with a plurality of image output including a first image, a second image set to become at least a part of an image that is not correlated with the first image when luminance values of pixels of the first image are added to it, and a third image set to become an image, which is obtained by adding luminance values of pixels of all pluralities of images, higher spatial-frequency components than those of the first image. The image processing apparatus has an optical shutter control unit for controlling an optical shutter provided between the display device and a viewer to make the shutter be in a light transmission state while a part of or all the first image is displayed, and in a light interception state while other images are displayed.

A display device is provided with a display section; a drive section driving the display section; and a light shutter control section controlling a light shutter. The display section is configured to display first and second images on the display section during a specific period. The drive section is configured to allow perceiving an image only from a direction in a specific viewing angle range at least during the specific period. The light shutter control section controls the light shutter so that the light shutter is placed into a transmitting state allowing transmitting light during a period during which the first image is displayed in the specific period and placed into a shielding state shielding light during a remaining period in the specific period. The first and second images are generated so that an image generated by adding brightnesses of respective pixels of the first and second images has no correlation to the first image.
摘要:
A light source is arranged at a side face of a light guide plate, and a beam direction regulator and a reflection plate are sequentially arranged at a side of the light guide plate opposite to an illumination direction. Furthermore, a transmittance/scattering switching device is arranged at an illumination direction side of the light guide plate. Light from the light source entering the light guide plate emerges in a direction opposite to the illumination direction, passes through the beam direction regulator, and is reflected by the reflection plate. The reflected light once again passes through the beam direction regulator, passes through the light guide plate, enters the transmittance/scattering switching device, and then emerges as light in a transmitting state or a scattering state. Thus, the occurrence of moiré effects and uneven luminance are suppressed, and an illumination apparatus capable of controlling an emerging light angular distribution is obtained.
