摘要： The invention provides a two-output low-noise down converter circuit which is improved in the isolation between two outputs. In the two-output low-noise down converter circuit, an input signal is divided into two divisional signals of different polarization systems and then the divisional two signals are processed by two-system signal processing circuits which comprise low-noise amplifiers, band-pass filters, frequency converter circuits and a local oscillator, respectively. The two-output low-noise down converter circuit includes: a switching circuit for performing switching control on the outputs of the two signal processing circuits responsive to the voltages applied to two output terminals, and for selectively outputting two polarized signals to its output terminals; intermediate frequency amplifiers for amplifying the two outputs of the switching circuit and leading out the resulting outputs at the two output terminals; and a control circuit for controlling the turning-on and -off of the power of the intermediate frequency amplifiers responsive to loads of the two output terminals.

摘要： A rank order filter is disclosed in which the maximum value, the minimum value and the median value are determined in a 3.times.3 local area having three sample values in each of column and row. The three sample values in the 3.times.3 local area are rearranged in descending order of magnitude by column, and the maximum values or the minimum values in each column are compared with each other thereby to determine the maximum value or the minimum value in the 3.times.3 local area. Also, after comparing the median values with each other in each column, the maximum value in the column having the minimum median value, the minimum value in the column having the maximum median value and the median value in the column having the median median value are compared with each other. The result of comparison is used to determine the median value in the 3.times.3 local area.

摘要： A system is provided for producing image signals of a photographed subject image by a solid state image sensing device and for producing a brightness signal and line sequential color difference signals from the image signal. The subject image is sensed by the image sensing device which has a color filter formed thereon. First and second horizontal scanning lines of picture elements are alternately arranged and the picture elements are opposed to filter elements of the color filter. The first horizontal scanning lines separately transmit at least red light and green light and the second horizontal scanning lines transmit at least blue light and green light, to thereby obtain color image signals. The image signal thus obtained are signal processed to produce the line sequential color difference signals R-Y and B-Y. With this signal processing, the system can produce the image signals including the line sequential color difference signals by a simplified arrangement without impairing the color productivity.
