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： A color filter has a plurality of succesively arranged recurrent groups of different color stripes. An image pickup tube has a photoelectrical conversion target exposed to light passing through the color filter and an index signal generation pattern. The image pickup tube outputs a signal containing a color signal component determined by a carrier which is modulated with the individual color stripes of each recurrent group of the color filter. The output signal from the image pickup tube also contains an index signal component which depends on the index pattern. A first memory holds at least part of the index signal component. The index signal component held by the memory is periodically updated. A second memory holds a portion of the output signal from the image pickup tube which was obtained under conditions where a predetermined color light illuminates the photoelectrical conversion target via the color filter. A reference signal is generated in accordance with the index signal component read from the first memory and with the signal portion read from the second memory. A color signal is detected from the output signal of the image pickup tube by use of the reference signal.

摘要： A color filter has recurrent groups of different color stripes. An image pickup tube has a photoelectrical conversion target exposed to light passing through the color filter and an index signal generation pattern. The image pickup tube outputs a signal containing a color signal component and an index signal component which depends on the index pattern. The index signal component has a phase representing a present start position of each scanning line. A memory holds a portion of the output signal from the image pickup tube corresponding to an initial frame period which occurs under conditions where a predetermined color light is applied to the photoelectrical conversion target via the color filter. A reference signal reflects a signal read out from the memory. A color component is detected from the output signal of the image pickup tube by use of the reference signal. The reference signal contains an index signal component which has a phase representing a start position of each scanning line during the initial frame period. A closed-loop phase control system allows the present start position of each scanning line to remain essentially equal to the start position of the corresponding scanning line during the initial frame period. A phase or level shifter is interposed in a loop of the closed-loop phase control system.

摘要： In a single-tube color imaging apparatus, the pickup tube includes a photoelectrical conversion target and a filter having recurrent groups of different color stripes through which an optical image is passed to the target. The target is scanned by an electron beam to produce a video signal having a frequency inversely proportional to the intervals at which the recurrent groups are arranged. The video signal varies in phase with the relative values of primary color components contained in the image passing through the stripes of each group and in amplitude with the intensity of the primary color components. Prior to normal operation, the target is uniformly illuminated with light of a predetermined color to generate a reference video signal, which is stored in a field memory. During normal operation, the reference signal is repeatedly read out of the memory and compared by frequency and phase comparators with the video signal from the target. Frequency and phase control circuitry responds to the outputs of the comparators by controlling the frequency and phase relationships between the two signals so that they match in frequency and phase before being applied to synchronous detectors.

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： There is provided a polarization converter for producing a beam of linearly polarized light from a randomly polarized light. The randomly polarized light is separated into a first polarized light which is projected in a first predetermined direction and a second polarized light having a predetermined angular relationship with the first polarized light.

By providing a predetermined two-dimensional positional relationship between the first and third polarized lights, the beam of linearly polarized light is produced and advanced on the outside of the converter in a second predetermined direction.
