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： 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： A signal for a first scanning line including a picture element whose signal does not exist and a signal for a second scanning line adjacent to the first scanning line in the same field are obtained in the same period. Then, a coefficient representing the ratio of the level of the signal for the first scanning line to the level of the signal for the second scanning line is calculated. Multiplying by the coefficient the level of the signal for the second scanning line to thereby provide an interpolation signal. The interpolation signal is added to the signal for the first canning line.

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.

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： 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： In a solid-state imaging device, a chrominance signal different from a signal to be obtained at a specified time among a plurality of chrominance signals to be successively obtained from a solid-state image sensor is interpolated with the chrominance signal obtained directly before the time of interpolation, or with the chrominance signal of a picture element corresponding to the signal to be obtained at the time of interpolation based upon the subject being achromatic. The particular signal to be used for the interpolation is decided based upon the difference between the signal to be obtained at the time of interpolation and a signal of the same chrominance obtained one cycle before the time of interpolation, or the differences between signals obtained directly before the time of interpolation and to be obtained directly after the time of interpolation and the chrominance signals obtained one cycle before the times of these signals.

摘要： A signal read-out apparatus for a solid-state imager employing CCDs (charge-coupled devices) and CPDs (charge priming devices) includes a clamp circuit for eliminating reset noise generated in an amplifier provided at the output of the imager. For eliminating thermal noise of high frequency generated in the amplifier and incapable of being eliminated by the clamp circuit, a low-pass filter is provided in precedence to the clamp circuit. The frequency band of the low-pass filter is not higher than 1.5 times the frequency of a clock pulse signal for driving the solid-state imager. In place of providing the low-pass filter as a discrete component, a low-pass filter having the same characteristics may be constituted by a capacitance of the capacitor and ON-resistance of a switch incorporated in the clamp circuit. The capacitance of the capacitor in the clamp circuit is set to a value greater than the input electrostatic capacity of the amplifier.
