摘要： There is provided a photoelectric conversion device for an electro-magnetic radiation beam incident thereto, into a charge pattern, the electro-magnetic radiation beam carrying information intended to be recorded. The device has electrodes, a photo-conductive layer member laminated to the electrodes having maximum thickness and a surface defining the maximum thickness between the electrodes, and a gap defined between the surface and a recording member disposed to face the surface of the photo-conductive layer member. There is further provided an apparatus for recording a charge latent image without losing the high resolution. The apparatus has a photoelectric conversion device having an electrode and a photo-conductive layer member on which the charge latent image is generated by projecting an optical image carrying information signals to the photo-conductive layer member, and a recording member having an electrode and a charge holding layer member facing the photo-conductive layer member to form a gap therebetween. A predetermined voltage is applied between the electrodes of the photoelectric conversion device and the recording member to transfer the charge latent image to the charge holding member by spark discharge.

摘要： A spatial light modulator and a lighting system used in, for example, projection displays are provided. The lighting system has a polarizing plate optically disposed in parallel to a light modulating layer of the spatial light modulator, thereby orienting the polarization of readout light beams incident on the spatial light modulator in the same direction to increase the contrast of images projected on a screen. The spatial light modulator is provided with a coupling prism having a side surface opposed to an entrance surface on which the readout light beams are incident. The side surface is so inclined inward as to allow stray light in the coupling prism to go out of the coupling prism without being reflected, thereby eliminating a decrease in contrast of images with a screen caused by the stray light.

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 a heater and an electrode device which are disposed in opposed relation to the recording medium. The heater preheats the recording medium in accordance with a control signal from an external device and the electrode device applies an electric field to the recording medium after the heating, thereby completely erasing an image previously recorded in the recording medium. 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： Color image information is recorded on a recording medium. The recording medium includes a color stripe filter having different-color filter stripes. Marks are provided on the recording medium in correspondence with the filter stripes of the color stripe filter. A detection is given of the marks on the recording medium. During the recording of the color image information, color line sequential signals are recorded on the recording medium. The recording of the color line sequential signals is synchronized with the detection of the marks on the recording medium.

摘要： There is disclosed a recording/reproducing system comprising an optical system for directing along a path of an electromagnetic radio ray from an object toward a recording medium, and a recording head disposed in the path for generating a charge latent image onto the medium. The feature of the system resides in that the recording head (system) forms the detection region which is not entirely subject to the influence of the electromagnetic radio ray and which is provided in a portion of the charge recording region of the medium, and in that a reproducing system discriminates the polarity of charges or the recording mode of the charge latent image recorded onto the medium by detecting the charges in the dectection region.

摘要： A color separation stripe filter in a color image pickup apparatus in which a color image is focused on a photo-electric conversion target through the filter to be converted to an electrostatic image so as to generate a color multiplexed signal. The filter comprises a plurality of recurrent groups of three different color stripes successively arranged at periodic intervals. The first color stripe has a characteristic showing a peak transmission factor in a red color region, the second color stripe has a characteristic showing a peak transmission factor in a green color region which is substantially equal to the peak transmission factor of the first color stripe, and the third color stripe has a characteristic showing a negative peak transmission factor at a wavelength between 500 nm and 530 nm so as to produce first and second peak transmission factors in a blue region and said green region. The first peak transmission factor is substantially equal to each of the peak transmission factors of the first and second color stripes and the second peak transmission factor existing in the green color region to be 50% to 80% of each of the peak transmission factors of the first and second color stripes, a curve of the characteristic of the third color stripe in the green region being substantially similar in configuration to that of the second color stripe.

摘要： A single tube color video camera apparatus having a camera tube including a color separation stripe filter and producing an output signal containing a color multiplex carrier signal, utilizes an envelope detector for directly detecting the camera tube output signal to produce an envelope detection signal which varies in accordance with an electrical charge pattern of the tube target. Phase control of the color multiplex carrier signal extracted from the camera tube output signal is executed based upon the envelope detection signal, to thereby correct for color signal phase deviations caused by variations in light intensity of scenes viewed by the camera.

摘要： In a color television camera, a light ray from an object to be taken is split into a plurality of rays to be respectively incident on two or more solid-state imaging devices each equipped with a color separation stripe filter where the imaging devices are positioned so that pixels thereof are horizontally shifted by a predetermined distance from pixels of remaining imaging devices with respect to an image applied thereto. The imaging devices are driven in a sequence, and output signals therefrom are sampled in a sequence so as to produce a single multi-color video signal by combining the plurality of sampled signal components. With this arrangement, the frequency of color signal components within the multi-color video signal is increased from the frequency of each of the output signals from the imaging device. The sampled signal components may be further sampled so that a plurality of color signals corresponding to the colors of the color stripe filters are obtained and their levels are respectively adjusted for obtaining level-adjusted color signal which are then combined to produce a single multi-color video signal.
