    摘要： This invention relates to a color imaging apparatus having a plurality of image pickup tubes (13, 14, 15) which pick up respective optical images of primary colors decomposed from one optical image, and provides a color imaging apparatus holding a picture of high quality at all times in" such a way that the registration of the images of the respective image pickup tubes is performed even during the operation of the camera. To this end, among image signals, local image signals which satisfy predetermined requisites being the most favorable for the reference signals of the registration are selected by decision circuits (91, 92, 93) and are temporarily stored in a memory (94) so as to be used for the registration. The most favorable requisites of the image are thus achieved, namely no movement is involved, the contour is sharp, and the chroma is low.

    摘要： An electric image recording camera includes an imaging device (2) which converts optical information received through a lens (1) into an electric signal, and a recorder (5, 6) which records the information of one frame read out from the imaging device (2). An optical shutter (15) can arbitrarily set for a period of time for the imaging device (2) to receive the optical information. Means (19) are provided for stopping the read-out operation of the imaging device (2) while the optical shutter (15) is open, whereby the exposure time can be varied at will.

    摘要： Disclosed is a solid state television camera with solid state image sensor for converting an optical image into electrical signals, which is comprised of a pulse generator (30, 33, 34, 39) for generating a train of pulses with a frequency equal to the horizontal scanning frequency of a television system, a frequency divider (61) for frequency-dividing the pulse train into a signal with a frequency substantially equal to the vertical scanning frequency alternately in two modes of 1/n and 1/n+1 (wherein n is a positive integer), and a selective circuitry (63, 64, 65, 66 and 67 to 69) for forming a train of pulses with a desired vertical scanning frequency on the basis of the pulse trains derived from the pulse generator (34) and the frequency divider (61).

    摘要： A solid-state imaging apparatus having a two- dimensional array (1) of photosensors such as photo diodes and MOS type FETs through which the photo signals are read out when scanned by pulse generator (2). The apparatus enhances the signal-to-noise ratio of the output signal by reducing or eliminating noise components which mix with the photo signals. An analysis of the noise components has revealed a correlation in that a noise component of a certain polarity develops in the opposite polarity again after a period that is shorter than one horizontal scanning period by the duration of one horizontal scanning pulse. With note taken of the correlation, the solid-state imaging apparatus includes a delay circuit (62) and an adder circuit (63) which cancels the noise.

    摘要： An analog signal is stored in an analog memory device (2), while lower bits of a digital signal obtained by digitizing the analog signal is stored in a digital memory device (4). An analog signal reproduced from the analog memory device (2) Is corrected on the basis of a digital signal reproduced from the digital memory device (4). The corrected reproduced signal is stored in the memory device again, whereby a recursive storage system is constructed. A minute signal component degraded by noise in the analog storage is corrected with the digital signal, with the result that storage end reproduction of favorable signal-to-noise ratio are realized.
