    Abstract: PURPOSE:To prevent an effective picture display from lacking a part of both right and left ends by compressing the time base of a video signal in an effective horizontal scanning period, and extending the time base of the video signal in the horizontal scanning period for the share of compressed part. CONSTITUTION:At the second clock generating circuit 6, the generation circuit 11 of a modulation signal SM to change a clock frequency is provided and the generation circuit 11 is controlled based on a scramble code signal SC which is supplied to a terminal 12. The modulation signal SM is a signal having the same waveform with the compressing and extending state of the time base as shown at a figure and by a scramble code signal SC which is supplied at the first field, a modulation waveform equivalent to a straight line L1 in the figure is performed and the frequency of the second clock CK2 is controlled so as to be lower than a reference frequency at the first half setting an intermediate part 0 in the figure as a border and is changed continuously to be equal to the reference frequency at the intermediate part 0 and at the latter half of the intermediate part 0, it is controlled so as to be higher than the reference frequency in order.

    Abstract: PURPOSE:To improve picture quality by displaying a non-interlaced double scanning and processing a motion adaptive interpolation which is different at a still picture part or at a moving picture part. CONSTITUTION:A double scanning conversion means which converts a received television signal of an MUSE system to the television signal of a non-interlaced double scanning system is prepared and a signal converted by the means is displayed on a color picture tube 20 as a picture. An inter-four fields interpolation means 12 and a within-field interpolation means 9 are provided at the double scanning conversion means and the inter-four fields interpolation means 12 and the within-field interpolation means 9 are controlled by the output of a means 14 which detects the motion of the picture. And at the still picture part, the picture of a scanning line which is interpolated by the output of the inter-four fields interpolation means 12 is generate and at the moving picture part, the picture of the scanning line which is interpolated by the output of the within-field interpolation means 9 is generated. Thus, a sufficient resolution power is obtained.

    Abstract: PURPOSE:To reduce the unnecessary noises included in the brightness signal Y and color signal C, by providing 2 systems of circuit, for brightness signal and color signal, which makes Y/C separation by inter-frame signal processing, and by composing each circuit with circulating type filter. CONSTITUTION:Brightness signal Y and color signal C obtained from output terminal 14 and 21 are so established so that they may include more components of brightness signal Yf and color signal Cf caused by the inter-frame processing. In this case, the still image part operates with the loop of delay line 25, mixing and comparison circuit 26 and adder 24 which consist of brightness signal separation circuit, and the separation characteristics of the brightness signal becomes acute, and noise components are eliminated resulting in the brightness signal Yf. Also the still image part operates with the loop of delay line 30, mixing and comparison circuit 31, and subtractor 29 which consist of color signal separation circuit, and the separation characteristics of the color signal becomes acute, and noise components are eliminated resulting in the color signal Cf.

    Abstract: PURPOSE:To obtain a compact projector free of image distortion and color aberration and capable of adjusting the size of the picture and white balance by providing the polarizing plates that pass polarized lights of various colors and plural means to respectively detect lights of different colors that pass the areas other than those corresponding to the screens of transmitting liquid crystal. CONSTITUTION:A dichroic mirror 9 that reflects blue lights and transmits yellow lights is used. The blue lights along the X-axis reflected by the dichroic mirror 9 is reflected by a mirror 10, and then pass through a liquid crystal 11 controlled by the signals B from a controller 25 and are polarized. By impressing voltages corresponding to the signals B to the transparent electrodes of different picture elements, the polarization axis of the incident lights is controlled. The luminance signals corresponding to the luminance aberration which are successively derived from the photoelectric element in accordance with the picture scan, controls through an amplifier 37 the gains of AC drive amplifiers 30, 31, and 32. Thus, the luminance aberration of the picture is corrected.
