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.

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： 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 high resolution solid-state color imaging apparatus having two-dimensionally disposed photoelectric sensors are arranged in rows and columns each having a color spectral responsivity characteristic such as by employing color filters. Each of the photoelectric sensors is scanned so as to obtain an intensity signal with respect to each row of each field, and wherein scanning of each field is for the same number of rows as that of each frame. Intensity signals are obtained only by the scanned output of each row. Additional intensity signals equal to half the number of said first mentioned intensity signals are obtained by a 2:1 subsampling of bandwidth-restricted signals by a filter along the vertical temporal frequency, thereby realizing high vertical resolution by the photoelectric image sensors of conventional row numbers and having compatibility with a conventional NTSC system and, furthermore, eliminating aliasing distortion.

摘要： A packet switch identifies a communication flow carried across an IP network, observes the communication flow, and acquires statistics data thereof, such as the number of packets that passed through the switch, the number of discarded packets, time at which the packets arrived at the switch, and time at which the packets were sent out from the switch. The packet switch continues to acquire the statistics data on the communication flow while the communication flow continues. If the packet switch performs a relay function, it sends the locally obtained statistics data to the adjoining packet switch placed downstream. If the packet switch is a node placed on either end edge of the network, it gathers the statistics data obtained by and delivered from other switches in the network and sends the gathered statistics data to the network management system.

摘要： At each network node, a packet classification unit makes a judgement to transfer only a packet necessary to be processed by software to a packet processing program processor and transfer other packets directly to a routing processor. Processing history information indicating the process history executed at each network node on a network route is transferred to the other network nodes so that other network nodes can store the processing history information in respective processing history repository table. Each node refers to this table and further transfers only the packet necessary to be processed by software to the packet processing processor.
