These drawings and the written description are not intended to limit the scope of the inventive concepts in any way, but to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments.
Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the accompanying claims.
On many electronic devices with screens, display power consumption is a non-negligible issue. Particularly, for mobile products such as mobile phone flat panels or commercial displays, which are sensitive to power consumption requirements, it is very important to reduce display power consumption. Typically, the screen is refreshed in a manner that several frames of images (e.g., 30 frames or 60 frames, etc.) are continuously refreshed within 1 second, which results in a large power consumption.
In the related art, for a specific display interface, such as the display interface of fig. 1, the interface is playing a video, wherein the hatched area is the playing area of the video, i.e., the refresh area. For the display interface of fig. 1, the terminal device may reduce power consumption by partially refreshing a portion of the screen, and the content in other areas is not refreshed, so as to maintain the previous still content. This partial refresh scheme reduces the power consumption of the display chip and panel by reducing the amount of data refreshed.
However, in an actual scene, global refresh and local refresh often occur alternately, and when the electronic device performs global image quality (PQ) enhancement processing, for example, global contrast improvement, the above local update method may result in that the data content of the whole frame of image cannot be obtained, and the processing effect of the PQ enhancement processing depending on the statistics information of the whole image is affected, so that the display effect of the screen is poor.
Therefore, the image processing method can acquire the local refreshing indication of the target video frame, then acquire the local data of the target video frame and the static data of the static area of the previous video frame of the target video frame, so as to determine the global data of the target video frame according to the acquired local data and the static data, thereby realizing global image enhancement processing on the target video frame, reducing the influence on PQ quality enhancement processing depending on the global data and enhancing the picture display effect.
In order to facilitate understanding, a structure of a display device to which the page refreshing method of the embodiment of the present application is applied will be described below with reference to an example of fig. 2.
Fig. 2 is a schematic structural diagram of a display device according to an example of the present application, referring to fig. 2, the display device includes: a preset memory 201, an image enhancement component 202, and a control driver module 203 for receiving upper layer commands.
The control driving module 203 may receive an upper layer command, where the upper layer command may include a local refresh indication, where the local refresh indication is used to indicate that a local refresh is performed from the target video frame.
The control driving module 203 may then determine the still data of the still region of the previous video frame of the target video frame and acquire the local data of the target video frame to determine the global data of the target video frame, and send the global data of the target video frame to the image enhancement component 202, so that the image enhancement component 202 performs global image enhancement processing on the target video frame according to the global data.
The preset memory 201 is used for storing static data, where the static data is data that is not refreshed when the display device is in a local refresh state, that is, static data in a static area. The static data may be static data of a static area of a video frame preceding the target video frame, where the static data may be used to determine global data of a frame subsequent to the target video frame when the frame subsequent to the target video frame is locally refreshed, where the local refresh area is unchanged.
In the embodiment of the present application, the display device may be any device having a display screen. The apparatus includes, but is not limited to: user Equipment (UE), mobile device, user terminal, wireless communication device, handheld device, vehicle mount device, etc. For example, some examples of terminals may be: a Mobile Phone (Mobile Phone), a tablet (Pad), a computer with wireless transceiving function (such as a notebook computer, a palm computer, etc.), a Mobile internet device (Mobile Internet Device, MID), a Virtual Reality (VR) device, an augmented Reality (Augmented Reality, AR) device, an augmented Reality (XR) device, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned (Self Driving), a wireless terminal in Remote Medical (Remote Medical), a wireless terminal in Smart Grid (Smart Grid), a wireless terminal in transportation security (Transportation Safety), a wireless terminal in Smart City (Smart City), a wireless terminal in Smart Home (Smart Home), a cellular Phone, a cordless Phone, a session initiation protocol (Session Initiation Protocol, SIP) Phone, a wireless local loop (Wireless Local Loop, WLL) station, a personal digital assistant (Personal Digital Assistant, PDA), a handheld device with wireless communication function, a computing device or a wireless terminal connected to a wireless modem, a wearable device, etc.
The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with specific embodiments. The following specific embodiments may exist alone or in combination with one another, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 3 is a flowchart of an image processing method according to an embodiment of the present application, where the method may be performed by a display device, or may be performed by an image processing apparatus disposed in the display device, and the apparatus may be a chip, or may be a chip module, or may be an integrated development environment (integrated development environment, IDE), and referring to fig. 3, the method includes the following steps:
s301, acquiring a local refresh instruction, wherein the local refresh instruction is used for instructing to execute local refresh from a target video frame.
The display device may obtain a local refresh indication indicating that a local refresh is to be performed starting from the target video frame.
It will be appreciated that the display device performs a global refresh for a video frame preceding the target video frame, for example for a video frame preceding the target video frame, referred to herein as a first video frame, for which the refresh state of the display device is a global refresh.
By way of example, the partial refresh state refers to a state in which only the contents of the active region are being refreshed and the contents of the other stationary regions are not being refreshed in the display interface of the display device.
The global refreshing state refers to that in a display interface of the display device, the content of the whole display interface is refreshed.
S302, acquiring first local data of a target video frame.
The refresh state of the target video frame is a local refresh state, and then the display device may obtain first local data of the refresh region of the target video frame to enable determination of global data of the target video frame.
For example, the first local data may include transition data of at least one transition region and activity data of at least one activity region.
S303, acquiring static data of a first static area of a first video frame, wherein the first video frame is a previous video frame of a target video frame.
After acquiring the first local data of the target video frame, the display device may acquire still data of a first still region of the first video frame.
S304, determining first global data of the target video frame according to the first local data and the static data.
After the display device obtains the first local data of the target video frame and the still data of the first still region of the first video frame, the first global data of the target video frame may be determined according to the first local data and the still data of the first still region.
Fig. 4 is a schematic diagram of a display device determining first global data of a target video frame according to first local data and static data of a first static area, and as can be seen from fig. 4, the first static area of the first video frame includes two areas, and accordingly, the static data of the first static area is composed of data of the two areas, and the first local data and the static data of the first static area may compose the global data of the target video frame.
S305, performing image enhancement processing on the target video frame according to the first global data to obtain an enhanced video frame of the target video frame.
After the first global data of the target video frame is determined, the display device can perform image enhancement processing on the target video frame according to the first global data to obtain an enhanced video frame of the target video frame, so that the global data of the target video frame can be obtained under the local refreshing state of the target video frame, and global image enhancement processing on the target video frame is realized.
For example, the display device may perform image enhancement processing on the target video frame according to the first global data, for example, may reduce backlight, global contrast enhancement, and the like.
In this embodiment, the display device may obtain a local refresh indication, where the local refresh indication is used to indicate that local refresh is performed from a target video frame, then obtain first local data of the target video frame, and obtain still data of a first still region of the first video frame, where the first video frame is a previous video frame of the target video frame, then determine first global data of the target video frame according to the first local data and the still data of the first still region, perform image enhancement processing on the target video frame according to the first global data, obtain an enhanced video frame of the target video frame, determine global data of the target video frame based on a characteristic that the still data of the still region is not refreshed, thereby reducing an influence on PQ quality enhancement processing depending on the global data, and enhancing a picture display effect.
Next, an image processing method provided in the present application will be described by way of example two.
Fig. 5 is a flowchart of another image processing method provided in the second embodiment of the present application, where the method may be performed by a display device, or may be performed by an image processing apparatus provided in the display device, and the apparatus may be a chip, or may be a chip module, or may be an IDE, etc., and referring to fig. 5, the method includes the following steps:
S501, acquiring a local refresh instruction, wherein the local refresh instruction is used for instructing to execute local refresh from a target video frame.
S502, acquiring first local data of a target video frame.
In order to acquire global data of a target video frame, the display device may acquire target first local data, and in particular, the display device may acquire first local data of the target video frame.
In the embodiment of the present application, a video frame corresponding to a display interface may be divided into three areas: a still region, an active region, and a transition region, for example, fig. 6 is a schematic diagram of a picture region of a display interface illustrated in the application, where the transition region is located between the still region and the active region, and the active region is overlapped on the still region, and transition data of the transition region is used for enhancing an image by an image enhancing component, and transition data of the transition region is not displayed in a page.
In one possible implementation, the first local data includes transition data of at least one transition region and activity data of at least one activity region, and the display device may obtain the first local data according to the following manner:
the display device may acquire the activity data of at least one activity area of the target video frame, acquire preset data from the activity data of the at least one activity area, and then determine transition data of the at least one transition area according to the preset data.
In one possible implementation manner, the display device may obtain the preset data from the activity data of at least one activity area by:
for any one of the active areas, the display device may determine an upper boundary and/or a lower boundary of the active area, and then determine preset data according to data of a preset range adjacent to the upper boundary of each of the active areas and/or data of a preset range adjacent to the lower boundary of each of the active areas.
Illustratively, in the example of fig. 6, the upper and lower boundaries of the active area are the boundary line 1 and the boundary line 2, respectively, the preset range may be a line interval, the data of the 6 th line is the data of the preset range adjacent to the upper boundary, and the data of the 12 th line is the data of the preset range adjacent to the lower boundary, that is, the preset data may include the data of the 6 th line and the data of the 12 th line.
In another possible implementation, the display device may obtain still data for a second still region of the target video frame, determine the second still region based on the still data for the second still region, and determine the at least one active region based on the active data for the at least one active region.
For any one of the active areas, the display device may determine a boundary between the second stationary area and the active area, and obtain preset data from the active data of at least one of the active areas according to the boundary.
For example, the still data of the second still region may be composed of a plurality of pixel data, each of which may include a pixel value and a pixel position, and the display device may divide the second still region in the target video frame according to the pixel positions of the plurality of pixels. And dividing at least one active region in the target video frame according to the activity data of the at least one active region.
For convenience of description, the display interface in fig. 6 is divided into a plurality of rows according to the same row spacing, as can be seen from fig. 6, the boundary 1 between the static area 1 and the active area is shown in the drawing, the display device may acquire the data of the 7 th row adjacent to the boundary 1 in the active area, and determine the data of the 7 th row as a part of preset data, where the part of the data of the preset data may be the data of the transition area 1, and as can be seen from the drawing, the transition area 1 overlaps with the area corresponding to the 6 th row of the static area 1.
Similarly, as shown in the figure, the boundary line 2 between the static area 2 and the active area may acquire the data of the 12 th row adjacent to the boundary line 2 in the active area, and determine another part of the preset data from the data of the 12 th row, where the part of the preset data may be used as the data of the transition area 2, and it is known from the figure that the transition area 2 overlaps with the area corresponding to the 13 th row in the static area 2. That is, in this example, the preset data is composed of two parts, namely, data of line 7 and data of line 12.
When the image enhancement component performs image enhancement processing on the display interface, for processing the active data of the active area, when the data processing is performed on the first row of the active area, for example, the 7 th row in fig. 6, the data of the transition area 1 can be acquired, and the data of the 7 th row can be subjected to data enhancement processing, for example, pixel value averaging, etc., so that the accuracy of data enhancement is improved by performing data enhancement on the transition data of the transition area relative to the data of the acquired still area or the complementary 0 pixels.
S503, obtaining second global data of the first video frame.
The refresh state of the display device for the first video frame is global refresh and the display device may obtain second global data for the first video frame.
S504, determining the static data of the first static area according to the second global data and the first local data.
Since the display device is in a local refresh state starting from the target video frame, i.e. the local area of the target video frame is refreshed, the display device displays for the non-refreshed area (i.e. the still area) by using the data of the still area of the first video frame.
Then, the still data of the first still region of the target video frame may be derived from the second global data of the first video frame and the first local data of the target video frame.
For example, as shown in fig. 7, the display device may determine an active area where first local data is located in the target video frame, determine data of the active area in the first video frame, and then determine data other than the data of the active area in the second global data as still data of the first still area of the target video frame.
S505, determining first global data of the target video frame according to the first local data and the static data of the first static area.
S506, performing image enhancement processing on the target video frame according to the first global data to obtain an enhanced video frame of the target video frame.
For the description of S505 and S506, reference may be made to the above embodiments, and the description thereof will not be repeated here.
It will be appreciated that for a subsequent video frame to the target video frame, which may be referred to herein as a second video frame, the second video frame is the video frame prior to receiving the global refresh indication or the region change indication, and the global data for the second video frame may be determined based on the still data of the first still region of the first video frame and the local data of the second video frame.
Specifically, the display device may obtain the active data of the active region and the transition data of the transition region of the second video frame, determine third global data of the second video frame according to the still data of the first still region, the active data of the active region of the second video frame, and the transition data of the transition region of the second video frame, and perform image enhancement processing on the second video frame according to the third global data to obtain an enhanced video frame of the second video frame.
The transition data of the transition region of the second video frame may be determined according to the activity data of the active region of the second video frame, and the display device may determine data of a preset range adjacent to an upper boundary and/or a lower boundary of the active region as the transition data of the transition region.
