Any number of terminal devices, networks and servers may be provided according to implementation requirements, and the terminal devices 101, 102 and 103 in the embodiments of the present application may specifically correspond to application systems in actual production.
Referring to fig. 2, fig. 2 shows a method for automatically adjusting color saturation according to an embodiment of the present invention, and the method is applied to the server in fig. 1 for illustration, and is described in detail as follows:
s201: and receiving the composite video signal, and decoding the composite video signal to obtain an image signal.
The above-mentioned composite video signal is also called CVBS signal, which is a video signal formed by transmitting the spectrum of the chrominance signal (C) with the spectrum of the luminance signal (Y) interposed therebetween, and the principle of spectrum interleaving is utilized to solve the problem that the spectrum of the luminance signal (Y) is scattered in the video signal, which leads to the problem of broadband waste. Specifically, the embodiment receives the composite video signal to be played, and decodes the composite video signal to obtain the frame-by-frame image signal, which is beneficial to processing the image signal subsequently.
Preferably, in the present embodiment, the decoding process is performed by using a Video decoder, which is a Video decoder, and the composite Video signal is decoded by the Video decoder to obtain a frame-by-frame image signal.
S202: detecting the color saturation of the image signal as the color saturation to be compared;
specifically, for each frame of image signal, its color saturation is detected, and the color saturation is taken as the color saturation to be compared.
S203: calculating the difference between the saturation of the color to be compared and the saturation of the standard color;
specifically, the standard color saturation refers to an optimal color saturation that can be adapted to the image signal, and is preset in advance, and when the image signal is input, a difference between the color saturation corresponding to the image signal and the standard color saturation is calculated.
And S204, when the difference value between the color saturation to be compared and the standard color saturation is not in the preset difference value range, adjusting the color saturation to be compared to obtain the target color saturation.
Specifically, in order to improve the efficiency of automatic adjustment of color saturation, a difference range between the color saturation to be compared and the standard color saturation, for example, -2% -2%, may be preset, and in order to ensure a good display effect, the difference range should be set to be not more than 5% at maximum and not more than-5% at minimum. And if the difference value of the color saturation to be compared and the standard color saturation is within the difference value range, the color saturation to be compared is not required to be automatically adjusted, and if the difference value is not within the difference value range, the color saturation to be compared is automatically adjusted until the difference value of the color saturation to be compared and the standard color saturation is within the preset difference value range, and the color saturation to be compared after the automatic adjustment is taken as the target color saturation.
Specifically, step S204 includes:
when the difference value between the color saturation to be compared and the standard color saturation is higher than the upper limit value of the preset difference value range, the adjustment difference value is reduced to the preset difference value range;
when the difference value between the color saturation to be compared and the standard color saturation is lower than the lower limit value of the preset difference value range, the saturation adjustment difference value is increased to the preset difference value range.
For example, the preset difference range is-2% -2%, when the difference between the saturation of the color to be compared and the saturation of the standard color is higher than 2%, the automatic adjustment difference is reduced to-2% -2%, and when the difference between the saturation of the color to be compared and the saturation of the standard color is lower than-2%, the automatic adjustment difference is increased to-2% -2%.
In addition, in an alternative manner of the implementation, the color saturation to be compared can also be directly and automatically adjusted to the standard color saturation, when the color saturation to be compared is equal to the standard color saturation, the color saturation to be compared does not need to be adjusted, and when the color saturation to be compared is not equal to the standard color saturation, the color saturation to be compared is automatically adjusted to the standard color saturation.
In this embodiment, the color saturation to be compared is automatically adjusted to a suitable color saturation range according to the relationship between the input color saturation to be compared and the preset standard color saturation, so that the user does not need to manually adjust the color saturation, and the efficiency of adjusting the color saturation can be improved.
Further, in step S104, adjusting the color saturation to be compared to obtain the target color saturation includes:
and sequentially performing Y/C separation, decryption processing, colorMatirx processing, white balance correction and gamma curve processing on the image signals to obtain target color saturation.
The Y/C separation is performed in the decoding process, and is mainly realized by a 2D or 3D comb filter, which is used for separating the video signal into a brightness signal (Y) and a chrominance signal (C), so that the problems of color fly, flickering and the like of a picture of a CVBS channel can be avoided. After the composite video signal is decoded, AFE processing and ADC sampling are carried out through an AFE processing module and an ADC sampling module, and the AFE processing module is also connected with the YBPR interface and the VGA interface. The AEF processing refers to analog front-end amplification, can normalize signals before entering the ADC sampling module, is beneficial to ADC sampling, and the ADC sampling module is also connected with an HDMI.
After ADC sampling, the image signal is subjected to Deinterlace processing, colormatrix processing, white balance correction, and gamma curve processing.
The de-interlacing process is also called de-interlacing process, and is performed before all interlaced signals enter the main control chip (e.g., MSD 306). The de-interlacing process is to convert an interlaced image signal into a progressive image signal for display, so that the sharpness and smoothness of a broadcast video picture can be improved.
The colormatrix processing, white balance correction and gamma curve processing are all processed in a Scalar Processor (scaler Processor), and image signals are directly sent to a display screen after the gamma processing. Through ColorMatirx processing, white balance correction and gamma curve processing, the color saturation of the image signal can be automatically adjusted to be within a preset range, so that the output color saturation can be adapted to the viewing requirement of a user.
In this embodiment, the color saturation of the film source to be played can be automatically adjusted by means of image quality processing such as Y/C separation, decryption processing, colormatrix processing, white balance correction, gamma curve processing, and the like, so that the playing image quality of the film source to be played and the efficiency of color saturation adjustment can be improved.
Further, as an implementation manner of this embodiment, the Deinterlace processing includes 2D einterlaces processing and 3D deinterlaces processing, and the control main control chip detects the motion index of each pixel in real time, adopts 2D deinterlaces processing for the moving pixels, and adopts 3D deinterlaces processing for the static pixels.
The 2D display is completed in the frame, and the moving picture is not seen as a problem, but the static picture is "flickering", especially a thin horizontal line, the 3D display is completed between frames, and the static picture is very well performed, but when the moving picture is dynamic, due to different detection algorithms, a short non-smooth picture may appear, and the moving picture is most easily generated at the moment when the picture is changed from static to dynamic. Therefore, 2 ddeinterlaced processing is adopted for the moving pixels, and 3D deinterlaced processing is adopted for the static pixels, in this embodiment, by detecting the motion state of each pixel in real time, and adopting different deinterlaced processing modes for the pixels in different motion states, a good de-interlacing effect can be achieved, and the definition and fluency of video playing are improved.
Further, the de-interlacing process includes:
if the static picture has the jitter problem, judging that only 2D decryption processing is performed, and adopting 3D decryption processing to eliminate the jitter problem;
if the problems of wire drawing and wire plugging occur in the dynamic picture, a register is adopted to forcedly carry out 2D gap processing, whether the problems of wire drawing and wire plugging are eliminated is judged, if the problems of wire drawing and wire plugging are not eliminated, 3D gap processing is continuously adopted until the problems of wire drawing and wire plugging are eliminated;
if the dynamic picture has the problem of saw teeth, judging that the dynamic picture is a problem of small-angle processing, and adopting the small-angle processing to eliminate the problem of saw teeth.
Specifically, after the de-interlacing process is performed, the played picture may have problems such as jitter, wire drawing, wire insertion and saw tooth, whether the problems are caused is determined in advance, if the problems are caused, a reason for the problems is found, and the image signal is sent to the scalar processor for processing after the problems are eliminated.
Specifically, if the above problem occurs, comparing whether the P signal (e.g. 720P) has a similar problem, if so, correcting the P signal, and if the P signal does not have, locking the problem in the default processing. If the static picture has the problem of jitter, judging that only 2D einterlaces are processed, adopting 3D deinterlaces to process and eliminate the problem of jitter, if the dynamic picture has the problem of wire drawing and wire plugging, adopting a register to forcedly process 2D deinterlaces to judge whether the problem of wire drawing and wire plugging is eliminated, if the problem of wire drawing and wire plugging is not eliminated, continuing adopting 3D deinterlaces to process until the problem of wire drawing and wire plugging is eliminated, if the problem of saw tooth appears on the dynamic picture, judging that the problem of saw tooth processing is the problem of small angle processing, and adopting small angle processing to eliminate the problem of saw tooth.
In this embodiment, corresponding measures are taken to eliminate problems existing after de-interlacing processing, so that the display effect of the playing picture can be improved.
Preferably, in another embodiment of the present application, before step S203, further includes:
and selecting a target category from preset adjustment categories based on the detected type of the current playing sheet source, and taking the color saturation of the target category as the standard color saturation.
Specifically, considering different tile sources, the color saturation required for achieving good viewing effect is different, so in this embodiment, different adjustment categories are preset for different kinds of tile sources, and each adjustment category corresponds to one color saturation. Detecting the type of a currently played film source according to an input composite video signal, automatically selecting a target type corresponding to the currently played film source from preset adjustment types, and taking the color saturation of the target type as a standard color saturation, for example, when the type of the film source is an ancient drama, selecting the color saturation of the A type as the standard color saturation; when the film source type is love play, selecting the color saturation of the B type as the standard color saturation; when the source is news program, the color saturation of C category is selected as standard color saturation.
In this example, by selecting appropriate color saturation as standard color saturation according to different kinds of film source types, and then automatically adjusting the color saturation of the input film source based on the standard color saturation, the played film source can achieve a better display effect.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present invention.
