A solid state color imaging apparatus with a color encoding filter and a solid state area imaging device for producing a color signal representing an optical image of an object. The color filter is formed from a plurality of pairs of color filter strips arranged one above the other in a vertical scanning direction, each of which color filter strips consists of alternating transmissivity filter elements of two different colors. The color filter is placed on the imaging device so that each photosensitive element of the imaging device is covered with a corresponding filter element. During the self-scanning of the area imaging device, first and second signals which represent color difference signals are derived therefrom alternately in the successive scan lines, from which the color signal is produced.

Solid state color imaging apparatus

Solid state color imaging apparatus for producing a color video signal representing an optical image of an object. In this apparatus, a plurality of sets of horizontal lines of photosensitive elements are arranged one above the other in a vertical scanning direction, each of which photosensitive element lines consists of a plurality of photosensitive elements distributed in a line in a horizontal scanning direction. Charge signals are read out from the sets of photosensitive element lines in each horizontal scanning period and a set of output signals is processed to produce the color video signal.

An apparatus for converging three electron beams accurately on the picture tube screen of a color television reproducing system. In this apparatus, a controlled pulse is produced from a deflection drive pulse which is supplied to the reproducing system as one of several synchronizing pulses separately from the color component signals, or is produced from a synchronizing pulse which is separated from the composite signal in the reproducing system. Desired tilt controlled parabola currents are produced from the sawtooth voltage which is generated from the controlled pulse the position of the leading edge and pulse width of which are preferably set for adjusting the phase of the convergence fields relative to that of the deflection field and to avoid causing a distortion of the resultant parabola currents at the end of the blanking period.
