摘要： The present invention relates to a color imaging device which suppresses false color signals appearing in an area where the difference of brightnesses is great in the horizontal or vertical direction.When the correlation between picture elements adjacent in the vertical direction is little and the false signal appears in a boundary part in the vertical direction, the false signal is detected, whereupon a color signal is demodulated by utilizing the correlation between the signals of picture elements in the horizontal direction. On the other hand, when the correlation between picture elements adjacent in the horizontal direction is little and the false signal appears in a boundary part in the horizontal direction, the false signal is detected, whereupon a color signal is demodulated by utilizing the correlation between the signals of picture elements in the vertical direction.As a result, the moire phenomenon attributed to the false color signals can be conspicuously reduced.While embodiments of the present invention refer to color imaging devices which employ MOS type solid-state imaging devices, the invention is also applicable to an imaging device which employs CCDs and a color image pickup tube which separates colors by means of a mosaic color filter.
摘要翻译：本发明涉及一种彩色成像装置，其抑制在水平或垂直方向上亮度差大的区域中出现的伪色信号。当在垂直方向相邻的图像元素之间的相关性较小并且在垂直方向上的边界部分中出现假信号时，检测到伪信号，由此利用彩色信号中的图像元素的信号之间的相关性来解调彩色信号水平方向。另一方面，当在水平方向上相邻的图像元素之间的相关性较小并且在水平方向上出现边界部分的假信号时，检测到伪信号，从而通过利用图像元素在垂直方向上的信号。结果，归结于虚假颜色信号的莫尔色现象可以明显减少。虽然本发明的实施例涉及使用MOS型固态成像装置的彩色成像装置，但是本发明也可应用于采用CCD的成像装置和通过马赛克滤色器分离颜色的彩色图像拾取管。

摘要： The chromatic aberration of the lens of a multi-tube color TV camera is separated into a linear component and a non-linear component. Horizontal and vertical deflection correction waveforms are generated in accordance with these two components. These two correction waveforms are superimposed onto horizontal and vertical deflection waveforms employed to deflect electron beams in said camera tubes. A registration error caused by the chromatic aberration of the lens is corrected with high accuracy by employing these correction waveforms.

摘要： A charge transfer device is made up of a plurality of charge transfer stages, each stage being composed of a plurality of capacitors and corresponding transfer electrodes. Signal charges are transferred from one stage to another by impressing clock pulses from a pulse supplying circuit to respective transfer electrodes. The pulse supplying circuit sequentially applies clock pulses which are adapted to transfer a signal charge to the initial capacitor of a respective stage during a fixed transfer time period, for a predetermined period of time within a variable time period corresponding to a delay period of time, to the respective transfer electrodes. The pulse supplying circuit also applies a clock pulse which is adapted to cause charges which are transferred to the initial capacitor to be retained therein, for the remaining period of time of said variable time period, this clock pulse being applied to a corresponding electrode of the initial capacitor.

摘要： A spatial frequency filter apparatus for suppressing spurious signals of the type generated in a color television camera incorporating a mosaic color encoding filter for multiplexing color signals includes two double refraction plates for filtering natural light introduced through a lens system in both the horizontal and vertical directions and an optical plate, such as a quarter wavelength plate or a rotatory polarization plate, interposed between the two double refraction plates. By causing natural light to transmit through the two double refraction plates and the optical plate before being introduced to the mosaic color encoding filter, the spurious signals are suppressed, whereby false color which may otherwise make an appearance at the contours of an image picked up by the color television camera can be significantly reduced.

摘要： A color imaging apparatus having a plurality of image pickup tubes which pick up respective optical images of primary colors separated from one optical image includes a registration control circuit which operates to hold a picture of high quality at all times by controlling the registration of the images of the respective image pickup tubes on a real time basis during the operation of the camera. To this end a circuit detects those local image signals which satisfy predetermined requisites which are most favorable for use as reference signals to control the registration and these detected image signals are temporarily stored so as to be used for the registration operation. The most favorable requisites of the local image areas selected for registration control are (1) those having no movement, (2) those having a contour which is sharp and (3) those having a chroma which is low.

摘要： Disclosed is a solid-state imaging device wherein optical information of a number of photo-electric conversion elements arranged in a matrix is read into vertical signal lines by a vertical shift register and then the optical information on the vertical signal lines is horizontally scanned by a horizontal register of a charge transfer device. Bias charge storage means and quasi-signal sweep-out drains are disposed between the horizontal register and the vertical signal lines, and a bias charge input means is arranged in the horizontal register. In order to ensure high efficiency in transferring signals between the vertical lines to the storage means, the sweep-out drains and the charge transfer device, it is arranged for bias charges to be provided at each stage of transfer. Thus, bias charges supplied from the storage means are used to transfer charges from the vertical lines to the storage means. Similarly bias charges directly injected from the quasi-signal sweep-out drains are used to sweep out quasi-signals from the storage means to the quasi-signal sweep-out drains. Finally bias charges supplied from the bias charge input means of the charge transfer device are used to read signals from the storage means into the charge transfer device. By virtue of this, the sweep-out efficiency of the quasi-signals from the capacitances which supply the bias charges and a read-out efficiency of the signal charges are enhanced and a high quality of video signal is produced.
