Background
A mobile terminal, an intelligent terminal, and the like, which are commonly used by people, are used as common devices capable of displaying images, and when the images are displayed, the images are displayed by adopting a fixed resolution. For example, when the display screen of such a device supports the highest resolution such as 2K and 1080P, the display screen will be displayed at the highest supported resolution when running an application program, mainly because the GPU of such a device can only render graphics according to the framebuffer size provided at the time of system initialization. Once the resolution is fixed, all of the display content will be displayed at that fixed resolution.
As the display resolution of such devices is increased, the refresh rate of the screen is increased, which poses a great challenge to the performance of the CPU and GPU in the device, as well as to the system power consumption, cruising ability, heat dissipation design, and the like. In order to solve the above problems, many equipment manufacturers adopt a technology of reducing resolution, but this operation will significantly reduce image quality, affect user experience, and cannot fully utilize a screen capable of supporting high resolution, resulting in performance overflow.

In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in themselves. Thus, "module" and "component" may be used in a mixture.
Referring to fig. 1, a schematic structural diagram of an image display system according to a preferred embodiment of the present invention is shown, in which the image display system includes three main components, an application processing unit (AP), an Image Processing Unit (IPU), and a display unit. An application processing unit (AP) is a unit that executes an operating system, a user interface, an application program, and the like, such as a CPU of a chip, or a functional module within the CPU, and the like. The Image Processing Unit (IPU) is connected between the application processing unit (AP) and the display unit via e.g. a mipi display interface, with the aim of providing full support for end-to-end data stream signal processing from Image Processing Unit (IPU) image input to the display unit. The display unit, such as an LED, LCD, etc., receives the image from the Image Processing Unit (IPU) and displays it, ultimately forming an image that is mapped to the user's vision.
To achieve the effect of switching between displays of different resolutions in an image display system, an application processing unit (AP) comprises:
two display elements
Two display elements (displays) are arranged in the application processing unit (AP), which may be elements connected with the external interface part in the application processing unit (AP) or connection elements which are assumed to be display functions. If the external interface is a mipi interface, the display element is an element which is directly connected with the mipi interface in the application program processing unit (AP), when the display element is manufactured in an actual scene, the mipi interface can be directly and programmatically divided into two independent interfaces, and the part of each independent interface connected with the application program processing unit (AP) is the display element; or two independent mipi interfaces are arranged on a hardware structure, and the part of each independent interface connected with an application program processing unit (AP) is a display element.
And the display element generates an image to be displayed according to an image display request sent in advance when the application program runs. When one or more application programs send out image display requests, the display element acquires the resolution requirements of the application programs, so that the image to be displayed also comprises the display resolution corresponding to the resolution requirements besides the image data.
The two display elements are in independent channels, i.e. the image transmitted from one display element will not be transmitted in parallel by the other display element. By setting the double channels and the double queues of the display elements, the practical requirements of application programs with different display resolution requirements can be differentiated. That is, when different applications have different display resolutions, different display elements are used as transmission carriers, and each display element displays an image to be displayed of one application, and another display element can dynamically adjust its own interface timing to match the desired display resolution of the next application. The images to be displayed corresponding to the same display resolution can be transmitted by the configured display elements without adjusting the interface time sequence of the display elements. Through transmission of different display elements, on one hand, differentiated management can be achieved, on the other hand, different display requirements can be independently achieved, and application program display with different display resolutions can be achieved.
Furthermore, considering that the number of two display elements is usually small compared to the desired display resolution of different applications, such as 4K, 2K, 1080P, 720P, etc. of the desired display resolution of all applications, the configuration of the display elements will be adjusted according to the time sequence variation of the applications. Specifically, for the display of an image, only one or two applications are usually displayed in the foreground of the display unit, and the display requirements of the different applications do not overlap in the time sequence range. That is, the application program generates the image display request in different time domains, and the display element dynamically adjusts its own interface timing sequence according to different display resolutions of different application programs in different time domains to meet the display resolution of the next application program. It can be understood that the non-simultaneous generation of the image display request will also make the display units have the reserved time to adjust the interface timing, that is, when one of the two display units is not in the image data transmission state, and the other is in the idle state, but one of the two display units is in the image data transmission state, and the other is dynamically changed according to the next application program which will display the image to be displayed.
In correspondence with the above configuration of the application processing unit (AP), the Image Processing Unit (IPU) includes:
-virtual elements
Generally, in order to display an image, an application processing unit (AP) is directly connected to the display unit to transmit image data to the display unit for display. In this embodiment, the addition of the Image Processing Unit (IPU) destroys the direct connection between the application processing unit (AP) and the display unit. Therefore, in order to control the application processing unit (AP) to work normally, the virtual unit in the Image Processing Unit (IPU) is virtualized as a display unit, and is connected with the display unit of the application processing unit (AP) through the display interface, so that the display unit can normally transmit the image to be displayed to the Image Processing Unit (IPU) through the display interface. Aiming at the setting of double display elements in an application program processing unit (AP), two virtual elements are also arranged in an Image Processing Unit (IPU), and one virtual element and one display element form a transmission channel of an image to be displayed.
-a processing unit
And a processing element for processing the image to be displayed is arranged in the image processing unit at the downstream of the transmission channel. The processing element is arranged to further enrich the display mode when the application program is displayed according to the operation of the user, for example, the processing element can be used for zooming the image to be displayed wholly or partially, enhancing the wholly or partially image (beautifying, adding a filter, highlighting, adjusting the contrast ratio and the like) or displaying the images to be displayed in a mixed (split screen) mode.
It is understood that the respective processing standards and processing manners are different for images to be displayed having different display resolutions. Therefore, two processing elements are also arranged, and one processing element is arranged on each image data transmission channel of the image to be displayed, namely, each virtual element is connected with one processing element.
-mixing element
The mixing element is connected with the two processing elements, and the images to be displayed after the images of the processing elements are processed are collected. The setting of the mixing element can simplify the load of the image display system, and all the images to be displayed can be uniformly transmitted after being collected. It is also understood that the number of the mixing elements may be one or more according to different working condition requirements, and when only one mixing element is provided, the mixing element is connected with the two processing elements; when there are two mixing elements, each mixing element can be connected with a processing element.
After the Image Processing Unit (IPU) with the configuration is arranged, the display unit is connected with the mixing unit through the display interface to receive the image to be displayed. Because the application processing unit (AP) and the Image Processing Unit (IPU) have established two image data transmission channels, and each image data transmission channel transmits display content required to be displayed by the application in the current time domain, when the application switches, the display resolution of the image to be displayed that can be transmitted by the display element is updated by adjusting the interface timing sequence of the display element, and then the image data is transmitted to the display unit for display through the different image data transmission channels.
In a preferred embodiment, the application processing unit (AP) further comprises an application control element, which, when the application generates an image display request, reads the image reality request including the display resolution to render the application on the different display elements and virtual elements. Specifically, the application control element, upon receiving the image display request, will also acquire the display resolution required by the application to display the image. The required display resolution may be a customary resolution (obtained empirically) when the content of the application is displayed, a resolution (obtained by sharing) generally adopted when other users run the application, a highest resolution supported under a configuration file of the application itself, and the like. Correspondingly, after the application program reads the display resolution, a configuration instruction is sent to the display element, and the configuration instruction also comprises the display resolution of the current application program. After receiving the configuration command, the display element modifies the original or initial configuration resolution according to the display resolution contained therein, i.e. adapts to the display resolution of the application program, so that the display interface of the display element can transmit the content of the resolution and refresh rate required by the application program.
Further preferably, when receiving an image display request generated by an application program, or when receiving an image display request generated by an application program for the first time after starting, the application program control element reads the display resolution of the application program, and sets the display resolution as the initial resolution, that is, performs corresponding initialization on the interface timing sequence according to the display resolution. When the display element is adjusted to have an initial resolution by the application program, it can be understood that, when the application program control element receives the image display requests having the same display resolution as the previous application program in turn, the display element may be directly used as the image transmission channel without adjustment because the initial resolution is matched with the display resolution. If the display resolution contained in the image display request generated by another application received by the application control unit is different from the initial resolution, the initial resolution is replaced with the display resolution of the subsequent application (the initial resolution and the display resolution are or are now included in the configuration instruction). The rear display unit stops receiving the image content of the previous application program and converts the image content into the image content of the next application program.
Further, as mentioned above, one display element, one virtual element, and one processing element connected to each other are defined as a first display channel, and the other display element, one virtual element, and one processing element connected to each other are defined as a second display channel. The image to be displayed of the first application program is transmitted through the first display channel, and when the display unit displays the image, the display element in the second display channel changes the interface time sequence of the display element according to the image display request sent by the next application program. On the contrary, if the latter application program is switched to the foreground of the display unit for displaying, the second display channel is enabled, and the display element in the first display channel changes the interface timing sequence of the display element according to the third application program or the image display request sent by the first application program and the program. The parallel processing mode of the adjustment of the second channel is transmitted through the first channel, so that the seamless switching of different resolution display can be realized when the application program is switched. That is to say, the two display elements sequentially receive image display requests sent by different application programs, sequentially generate images to be displayed, do not generate images to be displayed at the same time in the same time domain any more, and are realized by adopting a processing mode of 'cross parallel'.
In a preferred embodiment, the image display system is entirely built on the basis of the intelligent terminal, for example, the application processing unit (AP) is a CPU in the intelligent terminal or a module integrated in the CPU, the Image Processing Unit (IPU) is an image processing chip connected to the CPU or an image processing chip integrated in the CPU, the display unit is a display screen of the intelligent terminal, and the display interface is built on the basis of each electrical connection line of a main board of the intelligent terminal. Therefore, the connection between the application processing unit (AP) and the Image Processing Unit (IPU) is not limited to the connection using the connection wire, and other methods such as integration, welding on a motherboard, etc. are included in the connection method through the display interface.
In view of the rich and complicated applications, if some versions are older or the display content requires less resolution supported by the applications, even when the display queues built in the application processing unit (AP) and the Image Processing Unit (IPU) do not have corresponding resolutions, the process of searching upwards will be performed. Specifically, a threshold resolution is set in the application control element, when the application control element receives an image display request and the display resolution required by the switched-to application is smaller than the threshold resolution, a preset resolution of an upper level or an upper multi-level resolution closest to the display resolution and a display element corresponding to the searched preset resolution are searched, and then the application control element distributes the image to the display element for display. For example, if the display resolution of an application is 480P, if the application control element does not match the display element supporting 480P of the preset resolution, the application control element will search for the display element supporting 720P of the preset resolution, and if the display element does not match, the application control element will continue to search for the upper level until the display element matches. By means of the upward matching, firstly, normal display of the image can be guaranteed (the display element supporting high resolution is compatible with low resolution downwards), and secondly, the strong performance of the display queue supporting high resolution is utilized, so that the display quality and the system performance can be guaranteed. Thus, in some embodiments, the threshold resolution may be 2K, and the preset resolution include: 8K, 4K, 2K, FHD, 720P, etc. It can be understood that, when the hardware itself supports higher resolution, such as 16K, 32K, etc., a display queue combination of display elements, virtual elements and processing elements supporting the higher resolution can be added and established accordingly, so as to enrich the display mode of the image display system, and the adaptability is stronger.
In a further preferred or optional embodiment, since the preset resolution of the display unit of each intelligent terminal is different, the applications are not all optimized to have the universality that all intelligent terminals can display perfectly. Therefore, when the display resolution is different from the resolution of the display unit, the following processing will be performed. Specifically, the blending element is connected with the display unit, and acquires a target resolution, such as a pixel level and a display scale (4:3 or 16:9, etc.), which is possessed by the display unit itself in advance, and acquires the display resolution of each image to be displayed when the image to be displayed is received. The mixing element compares the display resolution with the target resolution, and when the display resolution is the same as the target resolution, or the resolution in a certain display direction (such as the length or width direction) is the same, and the display resolution does not exceed the target resolution in the other display direction, the display resolution is not adjusted, and the display resolution is transmitted to the display unit and then is directly displayed; when the display resolution and the target resolution are different in each display direction, the display resolution is preferably scaled in each display direction until the display resolution is the same as the target resolution, or the resolution in one display direction is the same and the display resolution in the other display direction does not exceed the target resolution. It is understood that the adjustment of the display resolution may also be an unequal adjustment in the display direction, directly matching the target resolution. And preferably is optimized closer to the target resolution at the display scale that preserves the display resolution.
It is understood that the "element" in the display element, the virtual element and the processing element in the present invention is only a lower description of the application processing unit and the image processing unit, and any other elements such as "device" and "device", "module" and "unit" that conform to the above-mentioned relationship are still within the protection scope of the present invention.
Example one
For example, the application processing unit is installed with application apps 0, apps 1, apps 2, …, appn, and the resolution of each application is res0, res1, res2, …, and resn (which may be the same or different). When the app0 is started, the initialized resolution of the first display element is configured to be res0 as a default, that is, the self interface timing is configured to be res0 as a default, and then the first display element is processed by the image processing unit and displayed in the foreground at the display unit. When app1 is started and is to be switched to the foreground of the display unit for display under the operation of a user, the second display element receives the image display request, adjusts the self interface timing sequence to use res1 as default configuration, and then processes the image by the image processing unit, and the image processing unit stops receiving the image content of the first display channel, receives the image content of the second display channel, and sends the image content to the display unit for display. When the app2 is started, the first display element receives an image display request of the app2, replaces the res0 with res2 in the interface timing sequence of the first display element, and after the initial configuration and the processing of the first display element by the image processing unit, the image processing unit stops receiving the image content of the second display channel, receives the image content of the first display channel, and sends the image content to the display unit for display. When the app3 is started, the second display element receives an image display request of the app3, replaces the res1 with res3 in the interface timing sequence of the second display element, and after the initial configuration and the processing of the second display element by the image processing unit, the image processing unit stops receiving the image content of the first display channel, receives the image content of the second display channel, and sends the image content to the display unit for display. And repeatedly switching the display resolution of different application programs between the first display channel and the second display channel so as to display the application programs with different display resolutions in the display unit.
It is understood that, in the above process, if the resolution of an application is the same as the resolution of the application after the reinitialization of the first display element or the second display element, the application control element may control the image data transmission of the application to take priority over the display channel with the same resolution. For example, when app3 is started, res3 of app3 is the same as res2 of app2, and the image content is transmitted by using the first display channel as the transmission channel without initializing the second display element, so that the image display process is smoother and less complicated.
Referring to fig. 2, in another embodiment of the present invention, a novel image display method may be implemented based on an application processing unit (AP), an Image Processing Unit (IPU), and a display unit. The image display method includes the steps of: s100: two display elements of the application program processing unit receive an image display request sent by at least one application program to generate an image to be displayed including display resolution; s200: when the application program sends image display requests to the display element in different time domains, the display element changes the interface time sequence according to different display resolutions of different application programs; s300: each virtual element of the image processing unit is connected with a display element through a display interface so as to receive the image to be displayed sent by the display element; s400: the processing element of the image processing unit is connected with a virtual element and performs image processing on an image to be displayed; s500: the mixing element of the image processing unit is connected with each processing element and collects the images to be displayed after the images of the processing elements are processed; s600: the mixing element is connected with the display unit through a display interface so as to send the image to be displayed to the display unit; s700: the display unit displays an image to be displayed based on the display resolution; s800: and when the interface time sequence of the display element is changed, the display element switches and displays the updated image to be displayed based on the updated display resolution.
The smart terminal may be implemented in various forms. For example, the terminal described in the present invention may include an intelligent terminal such as a mobile phone, a smart phone, a notebook computer, a PDA (personal digital assistant), a PAD (tablet computer), a PMP (portable multimedia player), a navigation device, etc., and a fixed terminal such as a digital TV, a desktop computer, etc. In the following, it is assumed that the terminal is a smart terminal. However, it will be understood by those skilled in the art that the configuration according to the embodiment of the present invention can be applied to a fixed type terminal in addition to elements particularly used for moving purposes.
It should be noted that the embodiments of the present invention have been described in terms of preferred embodiments, and not by way of limitation, and that those skilled in the art can make modifications and variations of the embodiments described above without departing from the spirit of the invention.
