Description
Technical Field
The present invention relates to the field of data processing, and in particular, to a video signal processing method and an electronic device.
Background
With the continuous development of electronic devices, the image resolution supported by the electronic devices is higher and higher. For example, the physical resolution of the screen of a commercially available 4K television can reach 3840 × 2160 pixels.
However, in displays that are currently in use, a significant portion of the supported image resolution is relatively low, for example only 1024 x 768 pixels. In practical applications, if the resolution of an image output by an electronic device outputting a video signal is greater than the resolution supported by a display, the display cannot display the image, and the display may have a black screen or the like.
In the prior art, in order to avoid the above situation, the electronic device may perform information interaction with the display. The Display may transmit Extended Display Identification Data (EDID) to the electronic device. The EDID contains parameters related to the display performance. The electronic device can recognize information such as the resolution supported by the display through the parameters. Therefore, the electronic equipment can automatically adjust the resolution of the output image so that the display can normally display the image.
However, there are still many displays that cannot provide correct EDID in the related art. When the video output port of the electronic device is connected with the displays, the display still cannot normally display the images when the resolution of the images output by the electronic device is not supported by the display because the information of the resolution supported by the display cannot be obtained. In general, in this case, the user can avoid the problem only by reinstalling the operating system or the like.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Fig. 1 is a flowchart of a video signal processing method according to embodiment 1 of the present invention. As shown in fig. 1, the method may include:
step 101: after a starting process of an operating system of electronic equipment is triggered, acquiring a first video signal with a first resolution output by a display chip of the electronic equipment;
the electronic device can be a desktop computer, a notebook computer and the like. The electronic device has a video output port. The electronic device to which the video output port is connected may be various types of displays. For example, a display supporting Video Graphics Array (VGA) format may be used.
The operating system may be various types of operating systems, such as Windows, Linux, etc. Taking the operating System of Windows as an example, the starting process of the operating System may be a process from when a start button of the electronic device is pressed, each element of the electronic device is powered on, and a Basic Input Output System (BIOS) is run until a desktop of the Windows operating System is displayed.
The video signal output by the display chip can also be a video signal in various formats. For example, it may be a video signal in DisplayPort format.
The first resolution may be a resolution of various sizes. The first resolution is typically a resolution that is not supported by the display.
Step 102: converting the first video signal into a second video signal of a second resolution;
the second resolution may be a resolution of various sizes. The second resolution is a resolution supported by the display.
Step 103: outputting the second video signal to a display unit;
the display unit is a display connected with a video output port of the electronic device.
Wherein the display unit supports at least the video signal of the second resolution.
In summary, in this embodiment, after a start process of an operating system of an electronic device is triggered, a first video signal with a first resolution output by a display chip of the electronic device is acquired; converting the first video signal into a second video signal of a second resolution; outputting the second video signal to a display unit; wherein the display unit supports at least the video signal of the second resolution; the resolution of the output video signal can be adjusted before the operating system is completely started, so that the resolution of the video signal output by the electronic equipment can be supported by the display, and the operating system does not need to be reinstalled.
Fig. 2 is a flowchart of a video signal processing method according to embodiment 2 of the present invention. As shown in fig. 2, the method may include:
step 201: acquiring a first instruction input by a user based on a basic input and output system; the first instruction is used for instructing the electronic equipment to output a video signal with a second resolution after an operating system is started;
the user may control the electronic device at the BIOS interface. A specific instruction may be set as the first instruction. And when the user inputs the first instruction, the electronic equipment is instructed to output the video signal with the second resolution after the operating system is started.
Step 202: and triggering the starting of the operating system in response to the first instruction.
After the first instruction is input, the electronic device may continue to execute the step of starting the operating system.
Step 203: after a starting process of an operating system of electronic equipment is triggered, acquiring a first video signal with a first resolution output by a display chip of the electronic equipment;
step 204: converting the first video signal into a second video signal of a second resolution;
step 205: outputting the second video signal to a display unit;
wherein the display unit supports at least the video signal of the second resolution.
In summary, in this embodiment, a first instruction input by a user based on the bios is obtained by setting the first instruction; before the operating system is completely started, a user can control whether the resolution of the video signal output by the display chip needs to be converted or not.
For example, when the user knows that the current resolution is a higher resolution and the resolution supported by the display currently connected to the electronic device is lower, the user may input the first instruction to control the electronic device to convert the resolution of the video signal output by the display chip.
It should be noted that the first instruction may further include specific information for resolution conversion. For example, the user may enter a desired converted resolution, e.g., 1024 × 768, via the first instruction. The electronic device may convert the resolution of the video signal to 1024 × 768 according to the first instruction.
Fig. 3 is a flowchart of a video signal processing method according to embodiment 3 of the present invention. As shown in fig. 3, the method may include:
step 301: after a starting process of an operating system of electronic equipment is triggered, acquiring a first video signal with a first resolution output by a display chip of the electronic equipment;
step 302: judging whether the first resolution and the second resolution of the first video signal are the same or not to obtain a first judgment result;
step 303: converting the first video signal into a second video signal of a second resolution when the first determination result indicates that the first resolution and the second resolution of the first video signal are different;
step 304: outputting the second video signal to a display unit;
wherein the display unit supports at least the video signal of the second resolution.
In this embodiment, before performing resolution conversion on the first video signal, it is determined whether the resolution of the first video signal is the same as the second resolution, and if the resolution of the first video signal is different from the second resolution, the conversion is performed, and if the resolution of the first video signal is the same as the second resolution, the conversion is not performed. This avoids unnecessary conversion of the resolution of the first video signal.
Fig. 4 is a flowchart of a video signal processing method 4 according to an embodiment of the present invention. As shown in fig. 4, the method may include:
step 401: after a starting process of an operating system of electronic equipment is triggered, acquiring a first video signal with a first resolution output by a display chip of the electronic equipment;
step 402: judging whether the first resolution of the first video signal is greater than the second resolution to obtain a second judgment result;
step 403: converting the first video signal into a second video signal of a second resolution when the second determination result indicates that the first resolution of the first video signal is greater than the second resolution;
step 404: outputting the second video signal to a display unit;
wherein the display unit supports at least the video signal of the second resolution.
Typically, a display is unable to display video signals above the maximum resolution supported by the display, but can display video signals below the maximum resolution supported by the display. In this embodiment, the second resolution may be a maximum resolution supported by the display unit. Before the resolution conversion of the video signal is carried out, judging whether the first resolution of the first video signal is greater than the second resolution, if so, the display unit cannot support the first resolution, and the resolution of the first video signal needs to be converted into the second resolution; if not, it may indicate that the display unit may support the first resolution without performing resolution conversion on the first video signal. Therefore, the conversion method in the embodiment can improve the conversion efficiency and avoid unnecessary conversion.
Fig. 5 is a flowchart of a video signal processing method according to embodiment 5 of the present invention. As shown in fig. 5, the method may include:
step 501: after a starting process of an operating system of electronic equipment is triggered, acquiring a first video signal with a first resolution output by a display chip of the electronic equipment;
step 502: converting the first video signal from a first packaging format to a second packaging format to obtain a video signal in the second packaging format;
because the packaging format of the video signal supported by the display unit may be different from the packaging format of the video signal output by the display chip. Therefore, the encapsulation format of the first video signal can be converted in this step. For example, when the first Video signal output by the display chip is in a DisplayPort format and the second Video signal is in a Video Graphics Array (VGA) format, the first Video signal in the DisplayPort format may be converted into a VGA format.
In practical applications, the first video signal may be converted into the second video signal with the second resolution by using a bridge chip having a function of converting the video signal in the DisplayPort format into the video signal in the video graphic array format.
Step 503: and converting the resolution of the video signal in the second packaging format from the first resolution to the second resolution to obtain the second video signal in the second packaging format at the second resolution.
Step 504: outputting the second video signal to a display unit;
wherein the display unit supports at least the video signal of the second resolution.
In this embodiment, the video signal in the second package format is obtained by converting the first video signal from the first package format to the second package format, so that the video signal output by the electronic device can be displayed by a display that is not supported by the display chip.
