Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Before explaining the embodiments of the present invention in detail, an application scenario and a system architecture related to the embodiments of the present invention are explained separately.
First, an application scenario related to the embodiment of the present invention is described.
The image updating method provided by the embodiment of the invention can be applied to a terminal with an electronic ink screen as a display screen. In a general case, a time image related to time, a weather image related to weather, a user-defined image, and the like may be displayed on the electronic ink screen of the terminal. When the terminal is in a screen locking state, if the installed application detects that the image currently displayed on the electronic ink screen needs to be updated, the terminal needs to perform image updating operation. The following describes a case where the terminal needs to perform image update in the embodiment of the present invention, by taking time image update, weather image update, and user-defined image as examples.
Time image
Since, in a general case, the time image displayed on the screen of the terminal may include the year, month, date, hour, and minute. Generally, the displayed time is accurate to minutes, and since the change of minutes to a certain degree causes the change of hours, the change of hours to a certain degree causes the change of dates, the change of dates to a certain degree causes the change of months, and the change of months to a certain degree causes the change of years, the time image needs to be updated once every time the displayed minutes change, that is, the time image needs to be updated once every minute by the terminal. For example, when the time is changed from 8 o 'clock 20 to 8 o' clock 21, the terminal needs to update the displayed time image from 8 o 'clock 20 to 8 o' clock 21.
Weather image
After the terminal is connected to the network, the terminal can acquire the relevant conditions of the current weather, if the weather conditions are not changed all the time, the weather image cannot be updated, and when the weather conditions are changed, the weather image needs to be updated. For example, when the weather condition changes from cloudy to light rain, the terminal needs to update the displayed weather image from cloudy to light rain.
User-defined images
The user can set a plurality of user-defined images, the terminal can update the user-defined images once at specified time intervals (2 minutes, 30 minutes and 1 hour), and the terminal can update the user-defined images of the plurality of users according to a set sequence or randomly. For example, a user sets a custom image a, a custom image B and a custom image C, when the currently displayed image of the electronic ink screen is the custom image a, if the display time of the custom image a reaches 2 minutes, the terminal needs to update the user-defined image, so as to update the displayed custom image a to the custom image B or the custom image C.
Next, a system architecture according to an embodiment of the present invention will be described.
Fig. 1 is a schematic structural diagram of an image update system according to an embodiment of the present invention. The system can comprise an application 1, a display management module 2, an ink screen control module 3 and a shared storage space 4. The application 1 may communicate with the display management module 2; the display management module 2 can communicate with the ink screen control module 3, and can store information related to the display control module into the shared storage space 4; the ink screen control module 3 can access the shared memory space 4.
The application 1 is configured to detect whether image updating is currently required, and send a first update notification to the display management module 2 when image updating is required; the display management module 2 is used for storing the target image in the shared storage space 4 and sending a second update notification to the ink screen control module 3 when receiving the first update notification; the ink screen control module 3 is configured to, upon receiving the second update notification, obtain a target image from the shared storage space 4, and display the target image for image update.
In addition, in the embodiment of the present invention, the operating system installed in the terminal may be an Android system or another operating system. The display management module 2 may be located in an application Framework layer (Framework) of an operating system installed in the terminal, the display management module 2 may be an epdmanager service (epdms) module, and the shared storage control may store information related to the application Framework layer; the ink screen control module 3 may be located in a Hardware Abstraction Layer (HAL) of the terminal-mounted operating system.
As can be seen from the above description, the image updating situation of the terminal may include multiple situations, and the terminal mainly updates the image through the application, the display management module and the ink screen control module. The specific operation of performing the image update will now be explained in detail with reference to fig. 2, which may specifically include the following steps.
Step 201: when the installed application detects that the image currently displayed on the electronic ink screen needs to be updated in the screen locking state, a first update notification is sent to a display management module, the first update notification carries a target image to be updated, and the display management module is a module which is independent from a display system in an installed operating system.
Therefore, when the time is changed, the weather condition is changed or the user-defined image display time is reached, the terminal needs to update the image, so that the application can detect the current time, the weather condition and the user-defined image display time, and determine whether the image currently displayed on the electronic ink screen needs to be updated.
The application can call a preset interface and send a first update notification to the display management module through the preset interface, and the preset interface is an interface which is externally provided by the display management module and used for accessing the display management module.
In addition, because the image updating situation of the terminal includes a plurality of situations (clock image updating situation, weather image updating situation and user-defined image updating situation), the image updating situation may only occur one at a time, for example, only the situation that the clock image updating needs to be performed occurs, or only the situation that the weather image updating needs to be performed occurs, or only the situation that the user-defined image updating needs to be performed occurs. It is also possible that multiple image updates occur simultaneously, for example, a clock image update, a weather image update, and a user-defined image update occur simultaneously, or any two of the above three image updates occur simultaneously. Therefore, when the application detects that the image currently displayed on the electronic ink screen needs to be updated in the screen locking state, only one image update may be detected, and multiple image updates may also be detected at the same time.
For example, the application may only detect that the time is changed from 8 o ' clock 20 to 8 o ' clock 21, or only detect that the latest weather condition is changed from cloudy to light rain, or only detect that the current time is the time for changing the custom image set by the user, or the application may also detect that the current time is changed from 8 o ' clock 20 to 8 o ' clock 21 and that the current time (8 o ' clock 21) is the time for changing the custom image set by the user, that is, the application may detect both the time image update condition and the user custom image update condition.
When the application only detects one condition that the image needs to be updated, the application can acquire a target image corresponding to the image updating condition and send the target image to the display management module; when the application detects multiple situations needing image updating at the same time, the application can simultaneously acquire multiple target images and send a first updating notice to the display management module, wherein the first updating notice carries the multiple target images. Of course, the application may also select one target image from the plurality of target images and send the selected target image to the display management module through the first update notification.
For example, when the application detects that the time image and the user-defined image need to be updated at the same time, the application may obtain the time image and the user-defined image at the same time, and send a first update notification to the display management module, where the first update notification carries two target images (the time image and the user-defined image). Alternatively, the application may acquire any one of the time image or the user-defined image, and send the acquired time image or the user-defined image to the display management module through the first update notification.
Step 202: and when the display management module receives the first updating notice, sending a second updating notice to the ink screen control module.
In a possible implementation manner, the first update notification may carry one target image (a time image or a weather image or a custom image), or may also carry a plurality of target images (at least two of the time image, the weather image and the custom image), and when one target image is carried in the first update notification, the display management module may directly send a second update notification to the ink screen control module, where the second update notification carries the target image.
In another possible implementation, the display management module may store the target image to a shared storage space, which is a preset space for storing information related to an application framework layer of the installed operating system. Since the display management module stores the target image, in order to ensure that the ink screen control module can accurately acquire the target image subsequently, the second update notification sent by the display management module to the ink screen control module may carry a storage path of the target image or an image identifier of the target image.
It should be noted that the image identifier of the target image is used to uniquely identify the target image, and the image identifier of the target image may be a name of the target image. In addition, the information of the application framework layer stored in the shared storage space may be information of modules included in the application framework layer, an application layout file, a process in which the application runs, and the like.
As can be seen from the above, the application may detect a situation of multiple image updates, and when the application detects the situation of multiple image updates, the first update notification sent by the application to the display management module may carry multiple target images, and at this time, for convenience of management, the first update notification may also carry image types; when the display management module receives the first update notification, the plurality of target images can be stored in the shared storage space according to the type of the carried image.
It should be noted that, because the display management module may obtain a plurality of target images at the same time, and the electronic ink screen updates only one image in the electronic ink screen at the same time, the display management module may select one target image from the plurality of target images according to a preset rule, and send a storage path or an image identifier of the selected target image to the ink screen control module through a second update notification.
It should be noted that the preset rule may be set in advance, for example, the preset rule may be that an image corresponding to an image update condition with the highest priority is selected according to a priority of the image update condition, where the priority is that the update of the time image is higher than the update of the user-defined image, the update of the user-defined image is higher than the update of the weather image, and the like; the preset rule may also be to select an image corresponding to an image update condition with the least number of image updates performed within a preset period (1 hour, 2 hours, one day, etc.) according to the history update record.
For example, when the plurality of target images carried in the first update notification are time images, weather images, and user-defined images, respectively, and the preset rule is that an image corresponding to the image update condition with the highest priority is selected according to the priority of the image update condition, the display management module may send the storage path of the time image or the image identifier to the ink screen control module through the second update notification.
Further, since the application sends the first update notification to the display management module, it is likely to carry not only the target icon image and the type of the target image, but also some spam information, such as various types of promotional advertisements. Therefore, in order to avoid displaying the spam information on the electronic ink screen, the display management module can also verify the security of the first update notification before sending the second update notification to the ink screen control module; when the security verification of the first updating notice passes, sending a second updating notice to the ink screen control module; when the security verification of the first update notification is not passed, no operation is performed, or the display management module sends prompt information to the ink screen control module, wherein the prompt information is used for prompting that the spam information exists in the first update notification.
The operation of the display management module for verifying the security of the first update notification may be: verifying the source of a target image carried in a first updating notice, determining that the first updating notice is not verified when the source of the target image is detected not to be a designated source, and determining that the first updating notice is verified when the source of the target image is the designated source.
It should be noted that the specified source may be set in advance, for example, the specified source may be a web page address, a file location in the terminal where a photo or an image is stored, and the like.
In addition, in the embodiment of the present invention, the display management module may verify the security of the first update notification by using the above method, and may also verify the security by using other methods, for example, the first update notification may carry a verification code, and the display management module may compare the verification code carried in the first update notification with the stored verification code, and when the two are the same, determine that the first update notification passes the verification; when the two are different, the first update notification verification is determined not to be passed.
Step 203: and when the ink screen control module receives the second updating notice, displaying the target image on the electronic ink screen to update the image.
In a possible implementation manner, since the display management module sends the second update notification to the ink screen control module, the target image may be directly carried in the second update notification, and therefore, when the ink screen control module receives the second update notification, the target image may be directly displayed on the electronic ink screen for image update.
It should be noted that, the ink screen control module displays the target image on the electronic ink screen, so as to perform the image updating operation, reference may be made to related technologies, and details of this are not repeated in this embodiment of the present invention.
In another possible implementation manner, since the second update notification sent by the display management module to the ink screen control module may carry the storage path of the target image or the image identifier of the target image, when the ink screen control module receives the second update notification, if the second update notification carries the storage path of the target image, the target image is obtained from the shared storage space according to the storage path of the target image; and traversing the shared storage space based on the image identifier if the second update notification carries the image identifier of the target image, so as to acquire the target image from the shared storage space.
In a normal situation, various images may be stored in the shared storage space, and the stored images are not all available for image updating, so that the ink screen control module acquires the target image according to the storage path or the image identifier of the target image, thereby preventing the ink screen control module from acquiring an incorrect image and improving the accuracy of image updating.
In the embodiment of the invention, when the application detects that the image currently displayed on the electronic ink screen needs to be updated, a first update notification carrying a target image can be directly sent to the display management module, and the display management module can send a second update notification to the ink screen control module based on the target image, so that the ink screen control module displays the target image on the electronic ink screen. Because the display management module is a module which is independent from the display system in the operating system installed on the terminal, when the image is updated through the display management module, the terminal does not need to carry out the bright screen operation, thereby reducing the power consumption of the terminal and prolonging the endurance time of the terminal.

The device comprises a display management module 301 and an ink screen control module 302;
the display management module 301 is configured to send a second update notification to the ink screen control module when receiving the first update notification;

and the ink screen control module 302 is configured to display the target image on the electronic ink screen for image update when receiving the second update notification.
Optionally, the display management module 301 is further configured to: storing the target image into a shared storage space, wherein the shared storage space is a preset space for storing information related to an application framework layer of an installed operating system;
correspondingly, the storage path of the target image or the image identifier of the target image is carried in a second update notification sent by the display management module to the ink screen control module.
Optionally, the ink screen control module 302 is configured to:
when the second update notification carries the storage path of the target image, acquiring the target image from the shared storage space according to the storage path of the target image;

Because the display management module is a module which is independent from the display system in the operating system installed on the terminal, when the image is updated through the display management module, the terminal does not need to carry out the bright screen operation, thereby reducing the power consumption of the terminal and prolonging the endurance time of the terminal.
