Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The application provides a resolution self-adaption method which is applied to a processor, so that the processor which does not support resolution self-adaption adjustment can adjust the self-resolution according to the resolution of a display.
Currently, a display generally uses an HDMI interface, and a processor that does not support resolution adjustment generally does not support the HDMI interface, i.e., the processor cannot access the display of the HDMI interface, so that resolution information of the display cannot be obtained, and further, the resolution of the display cannot be adjusted according to the resolution information of the display.
Therefore, in the embodiment of the present application, before the processor is enabled to implement the resolution adaptive method provided by the present application, the embodiment of the present application further provides an HDMI module, where the HDMI module is applied to the processor, so that the processor can access a display screen of an HDMI interface.
The HDMI module 100 includes: an HDMI interface 110 and an HDMI detecting unit 120.
The HDMI interface 110 is disposed at the display interface of the processor, and is used for replacing the original MIPI (Mobile Industry Processor Interface ) interface of the processor or other interfaces connected to the display with an HDMI interface, so that the processor can be connected to the HDMI display.
The principles and structures of the MIPI interface and the HDMI interface 110 may refer to the prior art, and are not described herein.
The HDMI detecting unit 120 is configured to detect whether or not there is an HDMI display insertion.
It can be understood that the HDMI interface is a hardware interface, and functions as a display supporting the HDMI interface to be accessed. The processor itself does not support the HDMI interface, i.e., the processor itself does not have a software program corresponding to the HDMI interface, and even if the HDMI interface is set on the processor, the processor itself cannot use the HDMI interface, and cannot detect an accessed device on the HDMI interface. Therefore, in the embodiment of the present application, whether HDMI is accessed may be detected using the HDMI detecting unit 120, thereby feeding back the detection result to the processor.
In an alternative embodiment, the HDMI detecting unit 120 may be a hot plug pin.
The hot plug pin is electrically connected with the HDMI interface, and can detect whether HDMI equipment is connected or not. When the HDMI equipment is plugged in, the HDMI interface of the HDMI equipment triggers a hot plug pin positioned in the HDMI interface of the processor, so that the level of the hot plug pin is changed, and similarly, when the HDMI equipment is pulled out of the HDMI interface, the level of the hot plug pin is also changed.
In some embodiments, HDMI device access may be characterized by a level increase of the hot plug pins and HDMI device removal may be characterized by a level decrease of the hot plug pins.
In an alternative embodiment, the HDMI detecting unit 120 may further include a pin to acquire EDID (Extended display identification data ) information. The pin is electrically connected with the HDMI interface for acquiring the EDID information from the HDMI device after the HDMI device is electrically connected with the HDMI interface. EDID information is information representing the display capability of the display according to the present application, and EDID is used to store capability data of the display, for example, to store resolution information of the display.
In this embodiment, the EDID information may be obtained through a pin to determine whether HDMI device access exists. For example, if the processor can obtain the EDID information, it indicates that the HDMI device is accessed, and if the processor cannot obtain the EDID information, it indicates that the HMDI is not accessed or has been unplugged.
For the above processor configured with the HDMI module, even if the processor can access the HDMI display, the processor itself does not change the resolution, but cannot output a display signal matching the resolution of the display.
Referring to fig. 1, fig. 1 is a flowchart of a resolution adaptive method according to an embodiment of the present application, where the resolution adaptive method includes:
s110, after the display is accessed, the resolution of the display is acquired.
If the processor is required to output the display signal according to the resolution of the display, the processor is required to determine the resolution of the display to adjust the display signal output by the processor, so in this embodiment, the resolution of the display can be obtained after the display is connected. Wherein, the display is HDMI display.
In an embodiment, after the display is accessed, identification information may be obtained from the display based on the HDMI module, the identification information being used to characterize a display capability of the display; the HDMI module is used for enabling the processor to be connected to the HDMI display; finally, a resolution of the display is determined based on the identification information.
In this embodiment, after the HDMI display is connected to the processor through the HDMI module, the processor may obtain EDID information of the display, that is, identification information, through the HDMI interface. The identification information carries resolution information of the display, and the processor can extract information of the resolution of the display from the identification information so as to determine the resolution of the display.
In some embodiments, the resolution of the display includes an optimal resolution, which may be a resolution corresponding to an optimal display effect that the display itself can achieve, and a resolution supported by the display, which refers to a resolution that can be displayed on the display.
In this embodiment, the processor may not be able to support all resolutions, and by acquiring the optimal resolution of the display and the resolution supported by the display, the processor may be enabled to reasonably select the resolution according to its own performance when adjusting the resolution, so as to determine the resolution with a better display effect from among the multiple resolutions for adjustment.
And S120, modifying the resolution parameter of the processor into a parameter value corresponding to the resolution of the display, so that the processor outputs a display signal to the display based on the modified resolution parameter.
In this embodiment, after the processor obtains the resolution of the display, the processor may adjust parameters used when generating the display signal according to the resolution of the display, so that the processor generates the display signal according to the adjusted parameter values.
Wherein the resolution parameter may limit the properties of the display signal. For example, the resolution parameter may be the user interface size, i.e. the size of the user interface in which the display signal is displayed on the display. Illustratively, the resolution parameter of the processor characterizes a user interface size of 1280×720, and the processor may output a display signal having a user interface size of 1280×720.
In an embodiment, before modifying the resolution parameter of the processor to a parameter value corresponding to the resolution of the display, it may be further determined whether the current resolution of the processor matches the resolution of the display.
If the current resolution of the processor is matched with the resolution of the display, the representation does not need to change the resolution, namely the current resolution parameter of the processor is a parameter value corresponding to the resolution of the display. If the current resolution of the processor does not match the resolution of the display, the characterization requires modifying the current resolution parameter to a parameter value corresponding to the resolution of the display.
In this embodiment, after the resolution of the display is obtained, the current resolution of the processor may be obtained, the current resolution of the processor is compared with the resolution of the display, if the current resolution of the processor is the same as the resolution of the display, it is determined that the current resolution of the processor is matched with the resolution of the display, at this time, the processor does not need to adjust the resolution parameter, and compared with the resolution parameter values corresponding to other resolutions, the processor can also output a display signal with a better display effect.
If the current resolution of the processor is different from the resolution of the display, i.e. does not match, the processor may adjust the parameter value of the resolution parameter so that the resolution of the processor matches the resolution of the display, thereby outputting a display signal with a better display effect.
In the above embodiment, the resolution of the display is the optimal resolution, and when the processor does not support the parameter value modified to the resolution parameter corresponding to the optimal resolution, the processor may modify the parameter value of the resolution parameter to the parameter value corresponding to the other resolution supported by the display.
In one embodiment, the resolution parameters include a display buffer frame size for characterizing a display signal data size to be output and a user interface layout, which is a display layout of the display signal on the display. Modifying a resolution parameter of the processor to a parameter value corresponding to a resolution of the display, comprising: the display buffer frame size and the user interface layout are modified to a value of the display buffer frame size and a corresponding user interface layout, respectively, corresponding to the resolution of the display.
The display buffer frame, also called "Display Framebuffer", is used to buffer the display signal transmitted to the display. It will be appreciated that the size of the display buffer frame characterizes to some extent the size of the display signal data volume being output, as the higher the resolution the larger the data volume of the display signal. Therefore, in the application, the size of the display buffer frame can be adjusted according to the resolution, so that the display buffer frame can buffer the display signal with the corresponding size of the resolution of the display. For example, when the resolution of the processor needs to be adjusted from 800×600 to 1280×720, the size of the display buffer frame may be increased, so that the display buffer frame can carry the display signal corresponding to 1280×720.
The user interface layout, i.e., the "Android ui" of the processor, is used to represent the size of the image after the display signal is displayed on the display, for example, the user interface layout may be the length and width of each image displayed, etc. By adjusting the layout of the user interface, the display can display an image with the size matched with the resolution of the display according to the display signal, so that the display effect of the display is improved. For example, when the resolution of the processor needs to be adjusted from 800×600 to 1280×720, the user interface layout can be adjusted to increase the length and width of the output display signal, so that the display displays the display signal output after the user interface layout is adjusted.
By adjusting the display buffer frame and the user interface layout, the display signals output by the processor can be matched with the resolution of the display from the data quantity and the image size, so that the display signals output by the processor have a good display effect on the display.
In one embodiment, after modifying the resolution parameter of the processor to a parameter value corresponding to the resolution of the display, the processor may generate the display signal according to the parameter value; converting the type of the display signal into a signal type matched with the display; and outputting the converted display signal to a display.
In this embodiment, the resolution parameter is used to limit the attribute of the generated display signal, and the processor may generate a display signal matching the resolution of the display under the limitation of the resolution parameter. The type of the signal output by the processor is the signal identified by the MIPI interface, and the type of the display signal which can be identified by the display is the signal of the HDMI interface.
Since the display signal output to the display by the processor is usually the signal output to the MIPI interface at present, the signal output to the MIPI interface cannot be identified by the HDMI device, in the embodiment of the present application, the type of the display signal output by the processor may be converted into the type of the signal matched with the display, that is, into the type of the signal that can be identified by the HDMI device, so that the display can normally identify the display signal and display the same. Thus, the processor is enabled to more fully support access to the HDMI display.
Furthermore, the resolution adaptation method described above may be implemented during the operation of the processor.
It will be appreciated that the processor typically performs the configuration of the various parameters of resolution during the start-up process, such as setting the display buffer frame size, etc., and the processor performs the configuration according to the resolution of the display during the start-up process, so in the current resolution switching mode, the processor is typically required to switch the resolution of the processor by restarting after the resolution of the display is acquired.
In the resolution self-adaption method provided by the application, after the resolution of the display is determined, the processor can configure various parameters related to the resolution in the operation process without restarting, so that the resolution switching efficiency can be effectively improved, and the user experience is improved.
In the embodiment of the application, the HDMI can unify the interfaces of the displays with different resolutions, and the processor is configured to support the HDMI interface, so that the processor can access the displays with different resolutions according to the HDMI interface so as to display the display signals by using the displays with different resolutions. After the display is connected, the resolution parameter of the processor is modified into a parameter value corresponding to the resolution of the display according to the resolution of the display, so that the processor can output a display signal matched with the resolution of the display, and when the display displays the display signal output by the processor, compared with the display signal output when the resolution is not matched with the resolution of the display, the display signal output by the modified resolution parameter can have a better display effect.
