The invention will be further explained by the description of the embodiments with reference to the drawings.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for testing a television display scale according to a preferred embodiment of the present invention. The method comprises the following steps:
and S10, acquiring the display scale of the video signal to be sent to the smart television, and controlling the smart television to configure the display scale.
Specifically, the video information is a preset video signal for sending to the smart television, and the video signal carries preset display content. Namely, when the intelligent television plays the video signal, preset display content is displayed on a display interface of the intelligent television. As shown in fig. 2, the preset display content is a black image carrying a preset number of white concentric circles, so that the acquired image of the display image of the smart television is a black image carrying a plurality of white concentric circles, and the center of the white concentric circle is located at the center of the image. Further, the preset contents carry a horizontal axis and a vertical axis, and the horizontal axis and the vertical axis pass through an image center point, respectively.
The different video information sent to the smart television has the same display content, and only the configured signal formats are different, that is, the display proportions corresponding to the video signals are different. Therefore, the preset image characteristics corresponding to the display proportion can be configured according to the preset display content, and the configured image characteristics are associated with the corresponding display proportion, so that the corresponding preset image characteristics can be found according to the display proportion. Correspondingly, an image feature list can be established in advance, and the display proportion supported by the smart television and the preset image features corresponding to the display proportions are stored in the image feature list. Meanwhile, the image feature list is associated with the model of the corresponding intelligent television, an image feature database is formed according to the image feature list corresponding to each intelligent television model, and the image feature database is stored.
In addition, after the display scale of the video signal is acquired, a remote control code needs to be generated to control the smart television to switch the display scale through the remote control code. Correspondingly, as shown in fig. 3, the obtaining of the display scale of the video signal to be sent to the smart television, and the controlling of the smart television to configure the display scale specifically include:
s11, generating a video signal to be sent to the smart television through a preset video signal generator, and extracting the display scale of the video signal;
and S12, generating a remote control code according to the display scale of the video signal, and controlling the smart television to configure the display scale through the remote control code.
Specifically, the video signal generator may generate a preset video signal and send the video information to the smart television, that is, the video signal generator is connected to the smart television in advance and may generate and send the video information to the smart television. The video signal is a fixed video signal carrying preset display content, and the video signal carries a display scale, that is, the display scale carried by the video signal can be determined according to the display scale carried by the video signal. In addition, after the display scale carried by the video signal is acquired, the remote control code can be generated according to the display scale, and the remote control code is sent to the smart television through the script, so that the smart television configures the display scale of the smart television according to the remote control code. Certainly, in practical application, the video signal generator may obtain a model of the smart television to be tested, and obtain a proportional mode supported by the smart television according to the model; and sequentially generating corresponding video signals according to the proportional modes, and after the test of one proportional mode is finished, sending a video signal corresponding to the other proportional mode so as to test all proportional modes supported by the intelligent television.
And S20, sending the video signal to the intelligent television, and collecting an image formed by the video signal on the intelligent television.
Specifically, the image is an image of a display screen formed by playing the video signal by the smart television. That is to say, after the video signal is sent to the smart television, the smart television plays the video information and displays a display picture corresponding to the video signal on a display interface configured by the smart television. And acquiring the display picture to obtain the image. In this embodiment, the image may be acquired by an acquisition card configured for the smart television, or may be acquired by a screen capture mode, or may be acquired by configuring a camera for the testing apparatus, and capturing a display interface of the smart television by the camera, where the image is acquired by any mode as long as the image can be acquired, which is not necessarily described here.
For example, as shown in fig. 4, the sending the video signal to the smart television and acquiring the image formed by the video signal on the smart television specifically include:
s21, sending the video signal to the smart television to control the smart television to display a video picture corresponding to the video signal;
and S22, collecting the video picture displayed by the intelligent television to obtain the image.
Specifically, the video frame is a display frame corresponding to the video signal, and preset display content is presented in the video frame, as shown in fig. 2, the image is a black background and carries several white concentric circles, and carries a horizontal axis and a vertical axis passing through a center point of the image.
And S30, extracting the image features of the image, and comparing the image features with the image features corresponding to the display scale.
Specifically, the image features are images carried by the images and used for judging the corresponding display proportions of the images, and different proportion modes correspond to different image features, so that the image features are extracted by searching extraction rules corresponding to the image features according to the display proportions and extracting the image features according to the searched extraction rules. The extraction rules and the corresponding relation between the extraction rules and the display proportion are pre-stored, and the corresponding extraction rules can be found according to the display proportion. The extraction rule may be found according to a display scale of a video signal corresponding to the image after the image is extracted, or may be found according to a display scale corresponding to the video signal after the video signal is generated, and the video signal, the display scale and the extraction rule are associated and stored in a temporary file, and after the image is acquired, the extraction rule is read from the temporary file, and the image feature of the image is extracted according to the extraction rule.
In this embodiment, the extraction rule is determined according to a display scale after the image is acquired. Correspondingly, as shown in fig. 5, the extracting the image feature of the image and comparing the image feature with the image feature corresponding to the display scale specifically includes:
s31, judging a proportion mode to which the display proportion belongs, wherein the proportion mode comprises 4:3, and other proportional modes supported by the smart television;
s32, when the display scale is 4:3, extracting the image features of the image according to a first extraction rule, and executing step S34;
s33, when the display scale is in other scale modes supported by the smart television, extracting image features of the image according to a second extraction rule, and executing a step S34;
and S34, comparing the image features with the image features corresponding to the display scale.
In particular, other scaling modes supported by the intelligence may include 16:9 and 16_9_ zoom _ up, etc. And the proportion modes supported by different models of intelligent televisions are also different, and other proportion modes supported by the intelligence are also different. For example, a television supporting only standard definition signals supports a scale mode of 4:3,16: 9, 16_9_ zoom _ up, cinema, and 14_9_ zoom, etc., the proportional modes supported by the tv supporting high definition signals are 4:3,16: 9, stretch _ zoom, wide _ zoom, wide _ zoom2, zoom2, etc. Correspondingly, a database is established in advance, the model of the intelligent television to be tested, the proportional mode supported by each model, the extraction rule corresponding to each proportional mode and the preset image characteristic corresponding to each proportional mode are stored in the database, and therefore the extraction rule corresponding to each proportional mode and the preset image characteristic can be found according to the proportional mode. In addition, the extraction rules corresponding to the same scale mode of different models of smart televisions are the same as the preset image features.
Meanwhile, in this embodiment, the first preset rule is to extract images within a preset range on the left and right sides of the image, and the number of white pixels carried by the images is 4:3, scale mode. The second preset rule is to extract various white pixel points contained in the preset position in the horizontal and vertical directions, and to take the number of the white pixel points contained in the horizontal and vertical directions as the image characteristics of other proportional modes supported by the smart television.
Accordingly, as shown in fig. 6, when the display scale is 4:3, extracting the image features of the image according to the first extraction rule specifically includes:
s321, when the display proportion is 4:3, respectively intercepting first images with preset sizes at the left side and the right side of the image in a proportional mode;
and S322, respectively obtaining white pixel points carried in the intercepted first image, and calculating the number of all the obtained white pixel points to obtain the image characteristics of the image.
Specifically, the ratio of 4: the image characteristic of the scale mode of 3 is that the left and right sides of the image each carry a black border of 12.5%. So that the preset size is 12.5% of the image resolution. For example, the image resolution is 1920 × 1080, that is, an image with a width of 1920 × 12.5% =240 pixels is cut on the left and right sides of the image. In this embodiment, the first image is captured by taking the coordinates of the pixel point at the upper left corner of the image as (0, 0) and the coordinates of the pixel point at the lower right corner of the image as (1919, 1079). Firstly, selecting (0, 0), (240,1079), (1680, 0) and (1919,1079) from the images, respectively taking a connecting line of (0, 0) and (240,1079) as an opposite angle and a connecting line of (1680, 0) and (1919,1079) as opposite angles, intercepting two rectangular images to obtain first images, and extracting the number of white pixel points carried by the two first images and recording the number as a first number; and finally, taking the first number as the image characteristic of the image. It is worth describing that, in this embodiment, the white pixels are pixels satisfying a preset condition, where the preset condition is that R, G and the B value are both greater than 150, and the extracted white pixels refer to pixels satisfying the preset condition.
As shown in fig. 7, when the display scale is in another scale mode supported by the smart television, the extracting the image feature of the image according to the second extraction rule specifically includes:
s331, when the display scale is in other scale modes supported by the smart television, respectively translating the central point of the image to the left/right and up/down by preset distances;
s332, extracting white pixel points contained in the horizontal direction and the longitudinal direction of the position of the center point of the moved image respectively;
and S333, respectively calculating the number of pixels of the white pixel points contained in the horizontal direction and the vertical direction, and generating the image characteristics of the image according to the calculated number of all the pixels.
Specifically, the preset distance is preset, for example, 10 pixels. Correspondingly, the step of respectively paralleling the image center point to the left/right and up/down by the preset distance means that one of four vertexes of a square with the image center point as the center and 2 times of the preset distance as the side length is selected. The lateral direction refers to a horizontal direction in which the center point of the image is located after the movement, and the longitudinal direction refers to a vertical direction in which the center point of the image is located after the movement. For example, the coordinates of the center point of the image are (960, 540), the coordinates of the pixel point obtained after moving left/right by the preset distance may be (950, y) or (970, y), and the coordinates of the pixel point obtained after moving up/down by the preset distance may be (x, 530) or (x, 550).
Further, after the central point of the image is translated, the white pixel points of the central point in the transverse and longitudinal directions are obtained, so that the influence of the horizontal white line and the vertical white line on the extraction of the white pixel points can be avoided, and the number of the white lines carried by the image can be accurately extracted. The white pixels are also pixels satisfying a predetermined condition, that is, R, G and B values are both greater than 150. Repeated white pixel points may exist when the white pixel points are extracted, and therefore after the white pixel points are extracted, deduplication processing needs to be performed to obtain the accurate number of the white pixel points. Correspondingly, as shown in fig. 8, the calculating the number of pixels of the white pixel points included in the horizontal direction and the vertical direction, and generating the image feature of the image according to the calculated number of all pixels specifically includes:
s3331, generating corresponding pixel point lists according to the white pixel points contained in the horizontal direction and the vertical direction respectively, and performing duplication elimination on each pixel point list by adopting a list circulation method;
s3332, calculating the number of pixels included in the corresponding direction according to each pixel point list after the duplication removal, and generating the image characteristics of the image according to the calculated number of all pixels.
Specifically, the specific process of performing deduplication processing by using a list circulation method may be: for a transverse pixel point list, taking out the coordinate value of a first white pixel point in the pixel point list, traversing all the white pixel points in the pixel point list, respectively calculating the distances between the first white pixel point and all the white pixel points except the first white pixel point, selecting all the pixel points with the distances smaller than the preset distance, and deleting all the selected white pixel points with the distances smaller than the preset distance to form a second pixel list; and then, taking out second white pixel points in the second pixel table, and repeating the process until all the repeated white pixel points are removed, so as to obtain the white pixel points contained in the transverse pixel point list, and extracting the number of the white pixel points. Correspondingly, the same method is adopted to extract the number of the white pixels contained in the longitudinal pixel point list. And finally, determining the image characteristics of the image according to the number of the horizontal pixel points and the number of the longitudinal pixel points.
In a modified embodiment of this embodiment, the removing process may be: and for the transverse pixel point list, calculating the distance between any two pixel points, classifying according to the calculated distance, and taking the number of the classified categories as the number of white pixel points contained in the transverse pixel point list. Correspondingly, the number of the pixels contained in the longitudinal pixel point list is obtained in the same way for the longitudinal pixel point list. The preset distance may be a length corresponding to 10 pixels.
And S40, determining the correctness of the display scale configuration of the intelligent television according to the comparison result.
Specifically, the comparison results include the same and different. When the display scale configuration of the intelligent television is the same, the display scale configuration of the intelligent television is correct, and when the display scale configuration of the intelligent television is different, the display scale configuration of the intelligent television is incorrect. In this embodiment, the preset image characteristics may be that 16:9 corresponds to 21 horizontal pixel points and 23 vertical pixel points; the longitudinal pixel point corresponding to the stretch _ zoom is 15, and the transverse pixel point is 23; the vertical pixel point corresponding to the wide _ zoom is 19, and the horizontal pixel point is 21; the longitudinal pixel point corresponding to the wide _ zoom2 is 15, and the transverse pixel point is 15; the longitudinal pixel point corresponding to the zoom2 is 15, and the transverse pixel point is 21; the longitudinal pixel point corresponding to the '16 _9_ zoom _ up' is 16, and the transverse pixel point is 19; the longitudinal pixel point corresponding to the cinema is 19, and the transverse pixel point is 21; the vertical pixel point corresponding to "14_9_ zoom" is 17, and the horizontal pixel point is 23.
