摘要： Disclosed is a two-dimensionally arrayed solid-state imaging device for a television camera having a photodiode array arranged at a photo-sensing section and a readout horizontal register constructed by a charge transfer device (CTD) such as a BCD, CCD or BBD. An inverter circuit is provided for each of the vertical signal lines. An input of the inverter circuit is connected to a vertical signal line drain of at least one transfer transistor arranged between the vertical signal line and the CTD, and an output of the inverter circuit is connected to a gate of the transfer transistor. Transfer efficiency is improved by the insertion of the inverter circuit and fixed pattern noise is substantially reduced by supplying bias currents.

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.

摘要： A signal processing apparatus for use with an imaging device having an image signal output circuit inherently generating noise in operation so that noise may be superposed on the image signal. The apparatus comprises a noise suppressor having a sampling and holding circuit for producing noise-suppressed pixel signals carrying different color information to contribute to suppression of noise superposed on the image signal and at the same time to demodulation of chroma signals representative of color components of an image and adders for producing a sum of and a difference between the noise-suppressed pixel signals to thereby produce a luminance signal and chroma signals for an image. The apparatus may further comprise a gain control circuits interposed between the sampling and holding circuit and the difference producing adder so that the amplitudes of the noise-suppressed pixel signals are leveled to improve the color purity of an image reproduced from the image signal.

摘要： An image pickup apparatus for a television and a depth-of-field control apparatus used in the same. Image signals corresponding to a plurality of picture images different in focal point or length position are obtained by a mechanism for changing a focal point or length position to produce a new image signal by composing these image signals through a composition circuit, and motion information of an object is obtained by a circuit for detecting a moving portion in the object to control the image composition by the motion information. The focal point or length position is moved in synchronism with an integer multiple of a vertical scanning period of the television. The image signals corresponding to the plurality of picture images different in focal point or length position are obtained within one vertical scanning period determined by the system of the television. The amount of movement of the focal point or length position is controlled in conjunction with a value of a lens aperture of the camera lens. The image composition is controlled by a composition control circuit made up of a circuit for detecting individual powers of image signals corresponding to a plurality of different picture images, a circuit for comparing the detected powers with each other, and a circuit for detecting the position of an edge included in one of the image signals, wherein a control signal for the image composition produced by the power comparison circuit is compensated by the edge position information obtained by the edge detection circuit.

摘要： In an image pickup apparatus, an interpolation signal for interpolating a discrepancy of registration is calculated from signals of (M.times.N) pieces of arranged elements (M, N being an integer, respectively) the positions of which on a light receiving plane are mutually adjoined with each other among arranged elements corresponding to signals in 2 fields which are continuously output from the respective image pickup elements, whereby the registration error can be corrected. An image pickup element has such a structure that signals having the same element number as an arranged element number corresponding to mutually continuous 2 field signals among the signals read during the normal interlace operation are entirely independently read every 1 field. By utilizing such an image pickup element having the element numbers two times higher than that of the conventional element, the registration error is interpolated from the signals of (M.times.N) pieces of the mutually adjoining arranged elements corresponding to the 1 field signal.
