1. a kind of signal processing method is it is characterised in that this signal processing method includes:

  • S1, the picture signal of acquisition original image;

    S2, the picture signal to original image carry out enhancing process, are not less than the final of original image to obtain pixel resolutionThe picture signal of image, wherein,The pixel resolution of described original image is selected from any one in multiple different pixels resolution ratio, described processing method bagInclude and obtain, using LVDS receiving port, the original image that pixel resolution is 1920 ×

    1080, be utilized respectively two different DVIReceiving port obtains the original image that pixel resolution is 3840 ×

    2160 and 7680 ×

    4320 original image, described finalThe pixel resolution of image is 7680 ×

    4320;

    Described signal processing method also includes:

    S5, the picture signal of described final image is converted into the picture signal with scanning sequence;

    AndCarried out before described step S1:

    Obtain excitation signal, get execution step S1 after described excitation signal;

    Described step S2 includes:

    S21, the picture signal of described original image is converted to middle YUV signal by rgb signal;

    S22, the Y-signal to described middle YUV signal carry out edge enhancing, respectively to the U signal in described middle YUV signal andAny one in the color level of V signal, black and white level and form and aspect is adjusted, to obtain enhanced middle YUV signal;

    S23, enhanced middle YUV signal is converted to middle rgb signal, described final figure is shown based on this middle rgb signalPicture;

    The pixel resolution of described original image is less than the pixel resolution of described final image, and described step S21 includes:

    S21a, the picture signal of described original image is converted to the YUV signal of described original image by rgb signal;

    S21b, the YUV signal to described original image are amplified, to obtain described middle YUV signal.
