Furthermore, in the description of the present application and the appended claims, the terms "first," "second," "third," and the like are used for distinguishing between descriptions and not necessarily for describing or implying relative importance.

At present, the detection of the TV board card can also be performed by capturing a picture of each channel as a reference picture, and then determining whether the TV board card is normal or not by comparing the detected picture output by the TV board card with the reference picture. Due to the fact that the picture quality parameter adjustment (PQ) is different in each TV board card, namely, the color parameter and the brightness parameter of the image of each TV board card are different through software adjustment, a reference image needs to be captured once when each TV board card is tested, and the detection efficiency is low. And the detection image output after the software adjustment of the TV board card may have a large deviation from the reference image, so that when the detection image has a deviation, it cannot be determined whether the deviation is caused by the software adjustment or the hardware circuit, so that the detected TV board card is inaccurate.
When the hardware circuit of the TV board card is detected, the software in the TV board card is adjusted and closed, and whether the hardware circuit in the TV board card is qualified or not can be accurately detected.
Fig. 1 is a schematic view of an application scenario of a method for detecting a TV board card according to an embodiment of the present application, where the method for detecting a TV board card can be used to detect whether a hardware circuit of the TV board card is qualified. The signal source 10 is configured to send an initial image to the TV board 20 to be detected. After receiving the initial image sent by the signal source 10, the TV board 20 to be detected generates a detection image by processing the initial image through a hardware circuit, and sends the detection image to the processor 30. After receiving the detection image sent by the TV board 20 to be detected, the processor 30 analyzes the detection image to determine whether the hardware circuit of the TV board 20 to be detected is qualified, so as to achieve the purpose of detecting the hardware circuit of the TV board.
The following describes in detail a method for detecting a TV board card according to an embodiment of the present application with reference to fig. 1.
Fig. 2 shows a schematic flow chart of a method for detecting a TV board card provided in the present application, and with reference to fig. 2, the method is detailed as follows:
s101, a detection image output by a TV board card to be detected is obtained, wherein the detection image is obtained after the TV board card receives an initial image sent by a signal source, a hardware circuit in the TV board card processes the initial image, an image quality parameter adjusting function in the TV board card is in a closed state, and the image quality parameter adjusting function is used for adjusting color parameters and/or brightness parameters of the image.
In this embodiment, the signal source is a device generating a signal, such as a DVD device or a set-top box.
In this embodiment, the detection image is an image obtained by processing an initial image through a hardware circuit after the initial image is acquired by a TV board to be detected. The function of adjusting the picture quality parameters in the TV board card is realized by software.
Since the color of a television picture is related to the display characteristics of the screen, different screens of the same picture display different. Some screens are default to be reddish or greenish, and in order to achieve the best display effect, the TV main board adjusts the image quality parameters of images through software to enable the screen to display normally, namely, the effect of not being reddish or not being greenish is achieved.
If the software adjustment and the hardware circuit adjustment of the image exist in the TV board card, when the TV board card is detected, if the detected image output by the detected TV board card is unqualified, the unqualified TV board card caused by the software adjustment or the unqualified TV board card caused by the problem of the hardware circuit in the TV board card can not be determined. Therefore, in order to detect whether the hardware circuit in the TV board is qualified, the function of adjusting the image quality parameters in the TV board is turned off, and the initial image is processed by the hardware circuit in the TV board, so that whether the hardware circuit in the TV board is qualified can be accurately detected.
In this embodiment, the processing, by a hardware circuit in the TV board, the initial image includes: and a hardware circuit in the TV board card adjusts the amplitude of the initial image.

In this embodiment, the image quality parameter adjusting function in the TV board needs to be turned off only after entering the factory test mode, and the image quality parameter adjusting function in the TV board is turned on in a normal condition or in the client mode.
S102, determining whether a hardware circuit of the TV board card to be detected is qualified or not based on the detection image.
In this embodiment, since the detected image is an image that has not been subjected to the adjustment of the image quality parameters by the software and has been processed only by the hardware circuit, it can be determined whether the hardware circuit in the TV board card to be detected is qualified by determining whether the detected image is qualified.
In the embodiment of the application, a detection image output by a TV board card to be detected is obtained firstly, the detection image is obtained after a hardware circuit in the TV board card processes an initial image after the TV board card receives the initial image sent by a signal source, an image quality parameter adjusting function in the TV board card is in a closed state, the image quality parameter adjusting function is used for adjusting color parameters and/or brightness parameters of the image, and then whether the hardware circuit of the TV board card to be detected is qualified or not is determined according to the detection image; according to the method and the device, the adjustment of software to the picture quality parameters in the TV board card is closed, so that the initial image is only influenced by a hardware circuit, the hardware of the TV board card can be accurately detected whether to have problems, the defects of lack of welding and few welding can be detected, the components and parts with problems in the TV board card hardware can be detected, and the quality of the detected TV board card is improved.
In a possible implementation manner, the method may further include:
and if the detection image is not acquired, determining that the hardware circuit of the TV board card to be detected is unqualified.
In this embodiment, the processor may acquire the detection image once at intervals, and if the detection image is not acquired, it indicates that there is a problem of open circuit, lack of soldering, or lack of soldering in the hardware circuit of the TV board, so that the initial image cannot be smoothly transmitted in the transmission process, and thus it may be determined that the hardware circuit of the TV board is not qualified.
In a possible implementation manner, before step 101, the method may further include:
and acquiring an initial image sent by the signal source, and taking the initial image as a reference image.
In this embodiment, since the function of adjusting the picture quality parameters in the TV board to be detected needs to be turned off when the method detects the TV board, no matter which type of TV board is detected, the same reference image can be used for comparison detection with the detection image without replacing the reference image, so that each channel is prevented from capturing a picture as the reference image, the detection efficiency is improved, and the detection of the TV board is simpler.
In this embodiment, before detecting the TV board card, an initial signal is captured from a channel of a signal source as a reference image, because the initial image is an initial image and is an image transmitted into the TV board card to be detected, and the initial image is used as the reference image to be compared with a detection image output by the TV board card, a comparison result can be more accurate, that is, whether the determined TV board card is qualified or not is more accurate.
In a possible implementation manner, the implementation process of step S102 may include:
and S1021, judging whether the detection image meets a preset requirement.
In the present embodiment, the preset requirements include a first requirement and a second requirement. The preset requirements can be set as required.

And S1023, when the detection image meets a preset requirement, determining that the hardware circuit of the TV board card to be detected is qualified.
In this embodiment, if the detection image meets the preset requirement, it indicates that there is no problem in the hardware circuit in the TV board, and the detection image output by the TV board has no problem, and the hardware circuit in the TV board is qualified.
