摘要： An image pickup device comprises an image pickup tube and an index generator having a light shield box; a light emitting diode held in the light shield box; a stripe screen provided on the photosensitive layer of the image pickup tube and shading compensation filter having transmittance pattern which equalizes illuminance variation on the stripe pattern of the stripe screen caused by the light emitting diode so that illuminance at any point of the stripe pattern becomes uniform. The image pickup tube generates picture signal together with index signal which is derived from the projected stripe pattern image on peripheral portion of the photosensitive layer through the shading compensation filter which equalizes index signal output level to make timing derived from the index signal accurate. A method of providing shading compensation filter is disclosed where a sheet of negative film is placed on the opening of the light shield box, exposed to the light emitting diode. Then the sheet of film is developed by chemical process.

摘要： An incident optical image is split by a single semi-transparent mirror into first and second optical images and directed onto first and second intersecting planes so that the images are in mirror-image relationship to each other with respect to a line of intersection between the two planes. First and second identical solid-state area imagers are located on the two planes, respectively. A pair of identical solid-state area imagers respectively include image sensors for generating charges corresponding to the optical images incident thereon. A vertically bidirectionally transferrable charge transfer device is coupled to each image sensor and a horizontally bidirectionally transferrable charge transfer device is coupled to the vertical transfer device. The vertical and horizontal charge transfer devices of both imagers are driven so that signals derived therefrom will produce identical electronic images.

摘要： A light-light transfer method using a spatial light modulator realizes an image display with a high utilizing of light without causing an undesirable residual image. The spatial light modulator is constituted to include two electrodes and at least a photoconductor layer member and a photo-modulation layer member used in a birefringence operating mode both being sandwiched between the two electrodes. A writing light is entered from the photoconductive layer member side so that its exposure value varies from the minimum exposure value to the maximum exposure value in a condition that a predetermined operation voltage is supplied between the two electrodes. In this instant, a voltage applied between both ends of the photo-modulation layer member corresponds to a voltage obtained by subtracting a voltage drop amount, occurring in the photoconductor layer member due to an incidence of the writing light, from said predetermined operation voltage applied in advance between said two electrodes. An operational condition of the spatial light modulator is set so that the voltage applied between both ends of the photo-modulation layer member becomes a voltage monotonously exceeding a voltage value corresponding to an extreme value of a degree of photo-modulation in a characteristic curve showing a relationship between an applied voltage and a degree of photo-modulation in the photo-modulation layer member, at the timing when the writing light of the maximum exposure value is entered into the spatial light modulator.

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： This specification discloses an image projector for projecting a tri-color composite optical image on a screen as a magnified optical image. A reading light beam emitted from a light source is separated into three color beams, e.g., Red, Green and Blue color beams through a tri-color separation and composition optical system. The separated color beams are irradiated on image forming devices provided correspondingly with Red, Green and Blue color images to read out color images respectively therefrom. Each of the reflected light beams from the image forming device carrying color image information impinges again on the tri-color separation and composition optical system to compose a composite image beam. The composite image beam is projected on the screen through an optical lens system comprising a first lens group, a second lens group and a third lens group disposed along an optical axis in order. The first lens group forms a composite color image on the second lens group by focusing the composite image beam from the tri-color separation and composition optical system. The second lens group converges the composite image beam therefrom to the third lens group. The third lens group projects the composite image beam on the screen as a magnified image. A focal length of the lens system is arranged shorter than a back-focal length defined as a distance between the front surface of the first lens group and a object focal point thereof.
