摘要： A color TV imaging apparatus comprises a TV imaging device for generating a composite color TV video signal by use of a color separation stripe filter, at least two demodulators for individually producing color signal components by demodulating a carrier signal which is generated as an output signal from the imaging device, and a bias light supply device for applying bias light to a photoelectric transducer section of the imaging device through the filter. At least one of the quantity and color temperature of the bias light is set such that the carrier color signals to be demodulated by the demodulators become greater than the peak-to-peak value of noise contained in the signal. The quantity of bias light is adjusted by controlling bias light sources of the bias light supply device, while a color temperature of bias light is selected by means of color temperature conversion filters positioned in light outlet portions of a flat light conducting element which is included in the bias light supply device.

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： In a color imaging apparatus, an optical image is focused on a photoelectrical conversion target of a color image pickup tube through a color stripe filter and converted to an electrostatic image, the latter being scanned line-by-line in rectangular raster form by an electron beam to generate a color multiplexed video signal. First and second index stripe electrodes are located adjacent to edges of the raster area to be scanned at the beginning of each field and at the beginning of each line. A memory is provided to store field and line index signals generated by the index electrodes as well as a reference video signal generated by the target illuminated with light of a predetermined color. During normal viewing operations, the stored signals are retrieved from the memory for frequency and phase comparison with signals generated by the index electrodes and the target to control the phase relationship between the retrieved reference video signal with the color-multiplexed video signal to effect synchronous detection therebetween at proper timing to produce primary color signals. The retrieved index signals prevent the loss of proper timing when the target is dimly illuminated.

摘要： In a single-tube color image pickup apparatus, an optical image is passed through a color stripe filter having recurrent groups of different color stripes to a photoelectrical conversion target, which is scanned by an electron beam to generate a video signal comprising a carrier having a frequency inversely proportional to the intervals at which the recurrent groups of filter strips are arranged. The carrier is modulated in phase with the stripes of each group and in amplitude with the intensity of the optical image. Prior to operation, the target is uniformly illuminated with light of a predetermined color to generate the carrier, which is stored into a field memory. During operation the memory is repeatedly addressed to generate a reference signal. The frequency of the reference signal is converted so that the video signal and the frequency-converted reference signal have a frequency ratio of 1:2 and an opposite phase relationship therebetween. A color demodulator receives these signals to derive a pair of color component signals for coupling to a matrix circuit to which a luminance component is also applied.

摘要： A color video signal processing device for a color image pickup apparatus which allows the saturation of a particular primary color to be enhanced with a good S/N ratio and without affecting the other colors. The image pickup apparatus generates a multiplex color signal which is made up of a low frequency range signal containing all the three primary color signal components and a high frequency range carrier signal modulated with first and second primary color signal components, which are predetermined by the colors of a color stripe filter installed in the image pickup apparatus, and in turn these signals and processed and transformed generally to three primary color video signals and a luminance signal. The low frequency range and high frequency range signals are separated from the color multiplex signal. The separated high frequency range signal contains a fundamental component and a harmonic component. The fundamental component is subjected to envelope detection. The signal level of at least one of the separated low frequency range signal and the envelope-detected signal is adjusted such that a third primary color signal component absent in the high frequency range signal is introduced into a difference signal produced by subtraction of the envelope-detected signal and the low frequency range signal.
