    Abstract: A double-scanning non-interlace television receiver with a vertical aperture correction circuit for receiving an interlace television signal having alternating odd and even fields of scanned lines which are interlaced, as displayed, comprises a receiver circuit which receives the interlace television signal and which generates interlace scanning line signals for each of the fields, a visual display apparatus, a non-interlace converting circuit which converts the interlace scanning line signals for each of the fields to non-interlace scanning line signals which are displayed on the visual display apparatus, with each of the scanned lines being scanned twice, and a high frequency emphasizing circuit which emphasizes the high frequency components of the interlace scanning line signals.

    Abstract: PURPOSE:To attain interlace display without switching a horizontal deflection frequency in the case of display of a still picture by providing a vertical deflection switching means so as to switch an electron beam twice each in one and same line. CONSTITUTION:When a detection circuit 21 decides a picture not to be a still picture, a connection switch 19 is opened, a deflection signal Svo is fed to a vertical deflection coil 20 and a color picture of noninterlace display is obtained on a picture tube 11. On the other hand, the detection circuit 21 decides the picture to be a still picture, the connection switch 19 is closed and a signal S'vo added with the deflection signal Svo is fed to the vertical deflection coil 20. Thus, two scanning lines by a same signal are formed on a same position in the noninterlace display through the double scanning of the electron beam on to the same line and a color picture of the interlace display is equivalently obtained.

    Abstract: PURPOSE:To easily attain each adjustment by operating a prescribed switch so that the data of prescribed adjustment items among adjustment items represent a maximum or a minimum data. CONSTITUTION:A set of data is transferred from a transmission section 50 to a shift register 101 and a data is latched (103) by a pulse from an AND circuit 104. An analog control voltage of each adjustment item is extracted by a D/A converter 103. Switches S0-S15 are in matrix connection and a dynamic scan pulse is supplied from a CPU 51 via a port 61 and fetched to the CPU 51 through a port 62. Moreover, the mode switch Sm is switched depending on the adjustment by the user and that by the maker and various significances are switched by the switches S0-S15. In case of the normal mode, the corresponding item is changed by one step at every operation of the switches S0-S15, but in case of the quick mode, the corresponding item is maximized or minimized only by operating switches S0-S15 once.
