摘要： A color imaging system for use as an electronic still camera, for example, includes a color separator for separating the optical image of a subject from a lens into a plurality of different color images, an optical shutter selectively openable for transmitting the optical image of the subject to the color separator, a photoconductive layer for converting the different color images into respective electric charge images, and an information recording medium for recording images corresponding to the electric charge images under an electric field developed between the photoconductive layer and the information recording medium. The timing with which the optical shutter is opened and the timing with which the electric field is generated by the power supply, are controlled by a control unit depending on imaging conditions selected by the user. The color imaging system also has an optical viewfinder for allowing the user to visually observe the optical image of the subject introduced by the lens.

摘要： A polyphase image signal generating device has a latch selection to latch original polyphase image signals of a first to an N-th phase original image signal (N being a natural number of two or more), and a selector connected to the latch section. The selector selects the original polyphase image signals in a first order from the first to the N-th phase original image signal or a second order from the N-th phase to the first original image signal, to output the selected polyphase image signals. The latch section may include N latches of a first to an N-th latch where an L-th original image signal and a {N−(L−1)}-th original image signal are latched by both an L-th and a {N−(L−1)}-th latch, L being a natural number of N or less. The selector selects the L-th original image signal in response to a control signal indicating the first order, whereas the {N−(L−1)}-th original image signal in response to another control signal indicating the second order.

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.

摘要： A first linearly polarized bundle of rays of incident rays is converted by optical modulation with an input video signal into a second linearly polarized bundle of rays orthogonal to the first rays in polarization. The first rays pass through a polarizer before optically modulated. A second linearly polarized bundle of rays originally involved in the incident rays is reflected by the polarizer in a first direction. The second rays obtained by the optical modulation are reflected by the polarizer in a second direction. The second rays reflected in the second direction pass through another polarizer. A first linearly polarized bundle of rays involved in the reflected second rays is reflected by the other polarizer. The reflected first rays is detected by an optical sensor that is positioned outside an optical path of the second rays originally involved in the incident rays and reflected in the first direction.

摘要： In an information recording apparatus, light containing information to be recorded is generated, and a photo-to-electric converting device serves to convert the light into a charge latent image. The photo-to-electric converting device includes a photoconductive member exposed to the light. Information corresponding to the charge latent image is recorded on a recording medium. A first recording device serves to record main information on a first region of the recording medium. A second recording device separate from the first recording device serves to record sub information on a second region of the recording medium. The second region is different from the first region.
