摘要： A clear color image having a high contrast ratio without particular coloration is displayed on a screen by improved display apparatus. Such display apparatus is comprised of a spatial light modulator including a photo-conductive layer, a photo-modulator layer and a dielectric mirror, a device for writing color images of different colors onto the spatial light modulator time-divisionally in a sequence of the different colors, a reading device for producing reading lights having different colors in synchronism with time-divisional writing of the color images, and for projecting the reading lights to the spatial light modulator, a driving device for supplying the spatial light modulator with different voltages and frequencies correspondingly with the reading light of different colors and in synchronism with time-divisional projections of the reading lights, and a device for projecting the color images read out from the spatial light modulator on the display device.The dielectric mirror may have a light absorbance characteristic controlled to be wavelength-selective to absorb a color of light to which the photo-conductive layer is most sensitive, so that lights having different colors leaked into the photo-conductive layer through the dielectric mirror are controlled to cause a uniform impedance of the photo-conductive layer.

摘要： An image formation apparatus using a recording medium including a scattering-mode light-modulation member which takes an opaque state in response to a heat and takes a transparent state in response to an electric field. The apparatus comprises an electrode device disposed in opposed relation to the recording medium and a charge removal device facing or in contact with the recording medium. The electrode device applies an electric field to the recording medium thereby completely erasing an image previously recorded in the recording medium and the charge removal device removes charge left in the recording medium due to application of the electric field by the electrode device. After the erasure, the recording medium is heated by a thermal head in accordance with an information signal from an external device so as to form a new image in the recording medium.

摘要： An optical system is disclosed which is for a display apparatus having a light source for emitting read light and a reflection type spatial light modulator for modulating the read light incoming thereto into in accordance with image written thereon. The modulated light is projected onto a screen by a projection lens to display the image. A field lens is provided between the modulator and screen at such a position that both the read and modulated light pass therethrough. The field lens focuses the modulated light on near an entrance pupil of the projection lens so that the intensity of the modulated light is increased.

摘要： The present invention provides an image processing apparatus for use with an image projector to allow the image projector to project a magnified image on a screen without a trapezoid distortion or a keystone distortion even when a normal line of the screen is declined to an optical axis of a projector lens of the projector. Digital image data from AD converter are stored in the image memory (6-9) through a selector (3). From the image memory, the image data of four pixels nearby a deformed coordinate position are read out through a selector (4). The image data of the deformed coordinate position is obtained by calculating an average of sum of arithmetic results obtained by giving a weight to each of image data of the four pixels. The weight given corresponds to a positional deviation value from the deformed coordinate position to the respective coordinate positions of the four pixels nearby the deformed coordinate position.

摘要： In a color image display apparatus, light beams intensity modulated by a green color image signal are deflected by an ocillating mirror, and then focused on a photo-conductive layer (PCL) member of a light-written type spacial light modulation element (SLM) through two focusing lenses for light write operation. Light beams intensity modulated by a time-axis compressed time-divisional image signal of two remaining colors (red and blue) are deflected by another mirror oscillated simultaneously with the ocillating mirror, and then focused on a PCL member of a SLM of the same type through two focusing lenses for light write operation. A read light beam is resolved into the light of the green wave length band and the lights of red and blue wave length bands, respectively, and then given to the SLMs, respectively for light read operation. The two read light beams reflected by the SLMs are synthesizing, and then projected on a screen through a common projection lens.
