Detailed Description

The technical solutions of the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which are obtained by a person skilled in the art based on the embodiments of the present application, fall within the scope of protection of the present application.

The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

In the RGB sub-pixels, the light emitting efficiency of the blue sub-pixel light emitting material is low, and a higher current is generally required to be applied to the blue sub-pixel to make the blue sub-pixel have similar brightness to the red sub-pixel and the green sub-pixel, which leads to an increase in the aging speed of the blue sub-pixel. Thus, over time, the RGB sub-pixels wear differently after the screen is used for a long period of time, resulting in uneven screen display brightness.

In view of this, an embodiment of the present application provides an image processing method, which may be used to solve the above technical problems.

The image processing method provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.

As shown in fig. 1, one embodiment of the present application provides an image processing method that can be performed by a processing chip, for example, the method can be performed by a single-display chip, i.e., can be applied to a single-display chip. The method may comprise the steps of:

step 101, obtaining target image data and compensation data of the target image data.

In practical applications, a Central Processing Unit (CPU) generally sends original image data without brightness attenuation to a display driving chip, and the display driving chip controls a screen to display an image based on the original image data. However, since the RGB sub-pixel loss of the screen is different, the display loss of each display area of the screen is different, so that the image displayed on the screen presents uneven brightness.

In the embodiment of the present application, the target image data acquired in step 101 may be the original image data without brightness attenuation. Then, acquiring the target image data in step 101 may include: target image data transmitted by a Central Processing Unit (CPU) is received, wherein the target image data is original image data without brightness attenuation.

In an embodiment of the present application, the compensation data may be used to compensate the target image data. The compensation data may be derived based on information related to the screen display. The information related to the screen display can be used for representing the display brightness attenuation condition or the display loss condition of each display area of the screen.

And 102, compensating the target image data based on the compensation data to obtain image compensation data, wherein the image compensation data is used for enabling the screen to display an image with uniform brightness.

The compensation of the target image data may be to compensate data related to display brightness in the target image data.

Further, after the image compensation data is obtained by the display driving chip, the brightness of at least a part of the area of the image displayed by the screen according to the image compensation data is changed compared with the brightness of the image displayed by the screen according to the target image data, so that the screen displays an image with uniform brightness. In this embodiment, the image displayed on the screen according to the target image data is an image which is affected by the screen display loss and exhibits uneven brightness display.

And step 103, outputting the image compensation data.

In the embodiment of the application, the single-display chip can output the image compensation data to the display driving chip, namely, the single-display chip outputs the image compensation data to the display driving chip. After receiving the image compensation data, the display driving chip can control the screen to display an image corresponding to the image compensation data. The single-display chip and the display driving chip can be arranged in the electronic equipment, and the single-display chip can be connected with the display driving chip.

It can be understood that by adopting the image processing method provided by the embodiment of the application, the image processing method comprises the following steps: acquiring target image data and compensation data of the target image data; compensating the target image data based on the compensation data to obtain image compensation data, wherein the image compensation data is used for enabling a screen to display an image with uniform brightness; and outputting the image compensation data. Since the target image data can be compensated, image compensation data which can be used for making the screen display brightness uniform image is obtained; further, when the screen displays an image based on the image compensation data, an image with uniform brightness can be displayed; thus, the problem of uneven screen display brightness in the related art can be solved.

In one embodiment, as shown in fig. 2, the acquiring compensation data of the target image data in step 101 includes:

step 1011, acquiring first display information corresponding to the target image data.

Wherein the first display information is information related to display of a screen. The first display information may be acquired in real time.

In an embodiment of the present application, the first display information may include at least one of gray-scale information, display brightness level information, frame rate information, display duration of the light emitting material, and temperature information of the light emitting material of the display screen.

When data acquisition is specifically performed, gray scale information, display brightness level information and frame rate information of a display picture can be acquired from a CPU. The display duration of the luminescent material may be obtained from a clock in the electronic device. The temperature information of the luminescent material may be obtained from a temperature sensor in the electronic device.

Wherein the frame rate information may be used for determining the compensation data on the one hand and for performing an interpolation process on the screen image display on the other hand. The frame inserting process is performed on the screen image display based on the frame rate information, and particularly, the following contents can be seen.

Step 1012, obtaining compensation standard data of the screen, where the compensation standard data indicates a correspondence between the first display information and the compensation information.

The compensation standard data may include a correspondence between a luminance decay condition of the screen display and compensation information.

When the information capable of reflecting the display brightness attenuation condition of the screen is the target information in the gray scale information, the display brightness level information, the frame rate information, the display time length of the luminescent material and the temperature information of the luminescent material of the display picture; accordingly, the compensation standard data may include a correspondence between the target information and compensation information. The target information may include any one or more of gray-scale information, display brightness level information, frame rate information, display duration of the luminescent material, and temperature information of the luminescent material of the display screen.

In the case where the compensation standard data includes a correspondence relationship between the target information and the compensation information, the information type of the acquired first display information may correspond to the information type of the target information. For example, the target information includes a display period of the light emitting material and temperature information of the light emitting material, and the acquired first display information may also include the display period of the light emitting material and temperature information of the light emitting material. Further, after the first display information is acquired, the compensation information corresponding to the first display information may be determined according to the correspondence between the target information and the compensation information in the compensation standard data. Thereby, an association relationship is established between the first display information and the compensation information.

Step 1013, determining compensation information corresponding to the first display information based on the compensation standard data, and using the compensation information as compensation data of the target image data.

In this step, the compensation information corresponding to the first display information is determined based on the compensation standard data, and reference may be made to the explanation in step 1012, which is not described herein.

It is understood that with the above-described scheme, by acquiring the first display information related to the display of the screen, the compensation standard data is set, and the compensation data of the target image data is determined based on the first display information and the compensation standard data. Thus, the compensation data can be accurately determined according to the attenuation condition of the screen display brightness, and meanwhile, the compensation data can be rapidly determined under the condition that the compensation standard data is set. Therefore, quick and accurate compensation can be realized on the target image data.

In implementation, the acquiring compensation standard data of the screen in step 1012 may include: and acquiring compensation standard data of the screen from a luminescent material aging database.

Wherein the luminescent material aging database stores the compensation standard data. The luminescent material aging database may be provided in an electronic device, for example, a display driving chip, and the single display chip may acquire the compensation standard data from the display driving chip. The luminescent material aging database may also be provided in a single-display chip. In addition, the luminescent material aging database can be arranged at the cloud end, and the single-display chip can acquire the compensation standard data from the cloud end.

In practical applications, the compensation standard data in the luminescent material ageing database may be generated in a number of ways.

Mode one: before the screen leaves the factory, carrying out aging test on the same batch of materials of the screen, and obtaining compensation standard data according to the aging test result. Then, the compensation standard data is prestored in a luminescent material aging database, and after a user starts to use the screen, the prestored compensation standard data is directly obtained from the luminescent material aging database.

Based on the compensation standard data, aging curves of the luminescent material at different temperatures can be obtained, and as shown in fig. 3, the aging curves corresponding to different temperatures comprise a corresponding relationship between the screen lighting time length and the screen display brightness proportion at the temperature. The luminance at which the screen is first lit may be regarded as a reference luminance at which no display loss occurs, and the reference luminance may be regarded as a display luminance ratio of 100%, as indicated by line a. Line B may represent an aging curve at low temperatures (e.g., 0 ℃). Line C may represent an aging curve at normal temperature (e.g., 25 ℃). Line D may represent an aging curve at high temperature (e.g., 45 ℃).

Further, after the first display information is acquired, the aging curve may be located based on the temperature information of the light emitting material in the first display information, and then the screen display luminance ratio corresponding to the aging curve may be determined based on the display duration (i.e., the screen lighting duration) of the light emitting material in the first display information. Further, the absolute value of the difference between the screen display luminance ratio and the display luminance ratio of the reference luminance may be used as the compensation data.

For example, the temperature information of the light emitting material in the first display information is displayed as a low temperature, the display duration of the light emitting material in the first display information is 1000 hours, the corresponding screen display luminance ratio is 98% as determined by the aging curve B, and then the compensation data is 2%. Further, the luminance data in the target image data can be compensated based on 2%.

For example, the temperature information of the light emitting material in the first display information is displayed as normal temperature, the display duration of the light emitting material in the first display information is 1000 hours, the corresponding screen display luminance ratio is 93% as determined by the aging curve C, and then the compensation data is 7%. Further, the luminance data in the target image data can be compensated based on 7%.

For another example, the temperature information of the light emitting material in the first display information is displayed as a high temperature, the display duration of the light emitting material in the first display information is 1000 hours, the corresponding screen display brightness ratio is determined to be 87% by the aging curve D, and then the compensation data is 13%. Further, the luminance data in the target image data can be compensated based on 13%.

It should be understood that, in the above embodiment of the present application, the correspondence relationship between the aging curve including the screen lighting time period and the screen display luminance ratio is only a specific example, and does not represent an undue limitation of the present application. In practical application, the aging curve can be established by using other kinds of information in the first display information according to practical situations.

Mode two: collecting second display information between the first lighting start and the target time node of the screen, wherein the second display information comprises at least one of gray level information, display brightness level information, frame rate information, display duration of the luminescent material and temperature information of the luminescent material of a display picture; and recording the acquired second display information in the luminescent material aging database.

Wherein the first-lit luminance of the screen can be regarded as the reference luminance. The target time node may be prior to the time node that acquired the first display information.

And, the second display information may be periodically collected a plurality of times from the first lighting up to the target time node. Since a larger data volume contributes to a more accurate compensation standard data to be established later, the interval time may be as short as possible when the second display information is acquired, for example, the second display information may be acquired every second.

In the embodiment of the application, based on the second display information acquired from the first lighting to the target time node of the screen, the change condition of the screen brightness from the first lighting to the target time node of the screen relative to the reference brightness can be obtained, and the change condition can be also understood as the screen brightness attenuation condition. Based on the change in screen brightness from the first lighting to the target time node, the trend of the change in screen brightness after the target time node can be predicted. The compensation standard data can be obtained by combining the change condition of the screen brightness from the first lighting to the target time node and the change trend of the screen brightness after the target time node.

In the second mode, the aging curve may also be obtained based on the compensation standard data, and the specific details of the aging curve may refer to the relevant content in the first mode, which is not described herein.

Recording the second display information in a luminescent material aging database, which can be used to determine compensation standard data on the one hand; on the other hand, follow-up tracking observation on the use condition of the screen can be facilitated.

In one embodiment, the screen includes a plurality of sub-regions; the acquiring the first display information corresponding to the target image data includes: acquiring first display information of each sub-area in a plurality of sub-areas; the determining compensation information corresponding to the first display information based on the compensation standard data includes: and determining target compensation information corresponding to the first display information of each sub-area based on the compensation standard data, wherein the target compensation information is compensation information adapted to the first display information of each sub-area.

The pixel density of each sub-region may be the same, or the number of pixels included in each sub-region may be the same. The size of the sub-area may be set according to the size of the screen resolution. For example, the larger the screen resolution, the fewer the number of sub-regions, the more pixels each sub-region contains; or for example, the larger the screen resolution, the more sub-regions, and the fewer the number of pixels each sub-region contains; the setting can be specifically performed according to actual needs. For example, when the screen resolution is 1440×3200, the number of pixels included in each sub-region is 8×8, and the number of sub-regions is (1440×3200)/(8×8).

In the embodiment of the application, the compensation standard data can comprise compensation standard data corresponding to each sub-region of the screen. Then, when the target compensation information corresponding to the first display information of each sub-region is determined, it may be determined based on the compensation standard data corresponding to each sub-region of the screen, respectively.

The target compensation information is compensation information adapted to the first display information of each sub-area, and it can be understood that after the target image data is compensated based on the target compensation information, the display brightness of each sub-area is the same when the screen is displayed subsequently. And the display brightness of each subarea is not higher than the display brightness of the first subarea before compensation.

For example, after compensation, the display brightness of all sub-regions (including the first sub-region) is lower than the display brightness of the first sub-region before compensation. Or displaying a subarea with higher brightness than the first subarea before compensation, wherein the display brightness is the same as the display brightness of the first subarea before compensation after compensation; in this case, the display luminance of the first sub-region does not change before and after compensation. The first subarea is the subarea with the lowest display brightness in all subareas before compensation, in other words, the first subarea is the subarea with the largest display loss and the highest material aging degree in all subareas before compensation.

Further, in one embodiment, the compensation information is a compensation parameter value; the determining target compensation information corresponding to the first display information of each sub-area based on the compensation standard data includes: obtaining a plurality of compensation parameter values corresponding to the plurality of subareas based on the compensation standard data; determining a target compensation parameter from the plurality of compensation parameter values, the target compensation parameter being a largest one of the plurality of compensation parameter values; and taking the target compensation parameter or a preset parameter value as the target compensation information, wherein the preset parameter value is larger than the target compensation parameter.

When the compensation standard data includes compensation standard data corresponding to each sub-region of the screen, the compensation parameter value corresponding to each sub-region may be determined based on the compensation standard data corresponding to each sub-region. The specific determination process may refer to the foregoing, and will not be described herein.

The compensation parameter value may be, for example, the absolute value of the difference between the above-mentioned display luminance ratio of the screen and the display luminance ratio of the reference luminance.

Then, for a plurality of sub-regions, the plurality of compensation parameter values may be absolute values of differences between the respective sub-region display luminance ratios and the respective sub-region reference luminance ratios. For example, the screen includes four sub-regions, and the four compensation parameter values corresponding to the four sub-regions may be 1%, 2%, 1.5%, 1%, respectively. Further, 2% of the largest compensation parameter value among the four compensation parameter values may be used as the target compensation parameter and the target compensation parameter may be used as the target compensation information, or a preset parameter value, such as 3%, that is 2% greater than the largest compensation parameter value (i.e., the target compensation parameter) may be used as the target compensation information.

The maximum target compensation parameter of the plurality of compensation parameter values is taken as target compensation information, and it can be understood that the area where the final screen display brightness is adjusted is a sub-area where the compensation parameter value is smaller than the target compensation parameter. For example, in the above example, the object of brightness adjustment is a sub-region in which the compensation parameter values are 1%, 1.5%, and 1%; the brightness of the sub-areas with compensation parameter values of 1%, 1.5% and 1% are adjusted to 98% based on 2%.

Taking the preset parameter value larger than the target compensation parameter as the target compensation information, it can be understood that the area with the adjusted final screen display brightness is all the areas, including the sub-area corresponding to the target compensation parameter. For example, in the case where the target compensation parameter is 2% as described in the previous example of the aging curve, the brightness of the screen display may be adjusted to 97% based on 2%, and the adjusted brightness change curve may be shown as line E. The target compensation parameter is 7%, and then the brightness of the screen display is adjusted based on 7%, the brightness of the whole screen can be adjusted to 90%, and the adjusted brightness change curve can be shown as a line F. The target compensation parameter is 13%, and then the brightness of the screen display is adjusted based on 13%, which may be that the brightness of the whole screen is adjusted to 84%, and the adjusted brightness change curve may be shown as line G. The mode for reducing the brightness of the whole screen can avoid the situation that the brightness of the compensated screen is still uneven caused by calculation errors of compensation parameter values of one or more subareas.

In a specific implementation, the adjustment of the display brightness may be achieved by adjusting the voltage.

It can be understood that, by adopting the above scheme, the screen is divided into a plurality of sub-areas, the first display information of each of the plurality of sub-areas is acquired, and the target compensation information capable of adapting to each sub-area is determined. Therefore, after the target image data is compensated based on the target compensation information, when the screen is displayed, the display brightness among all the subareas is the same, so that the display effect with uniform brightness can be displayed.

In one embodiment, the acquiring the first display information corresponding to the target image data includes: acquiring first display information under the condition that the screen is in a lighting state; the outputting the image compensation data includes: and outputting the image compensation data when the screen is powered on and lightened next time, so as to control the screen to display the image with uniform brightness based on the image compensation data.

The first display information may be acquired periodically at regular intervals when the screen is in the on state. For example, in the case where the screen is in the lit state, the first display information is acquired every 1 second. Thus, the latest information related to the display of the screen before the screen is turned off can be obtained. The compensation data is determined based on the latest information, so that the screen can be further ensured to display an image with uniform brightness when the screen is powered on next time.

In the embodiment of the application, the process of determining the compensation data and compensating the target image data based on the compensation data can be set at the screen-off stage between the current screen-on stage and the next screen-on stage.

If the image compensation data is calculated in the screen-off stage, but the screen is not powered on next time, the image compensation data may be stored first, for example, in a memory of a single-display chip. And outputting the image compensation data when the screen is powered on for the next time.

It can be appreciated that by adopting the above scheme, by acquiring the first display information when the screen is in the on state and outputting the image compensation data when the screen is powered on and turned on next time, the problem of display conflict which may be caused when the image compensation data is output in the current on stage of the screen can be avoided.

It should be noted that, in the image processing method provided in the embodiment of the present application, the execution subject may be an image processing apparatus, or a control module for executing the image processing method in the image processing apparatus.

The display driving chip can be used for receiving the image compensation data and controlling a screen to display images with uniform brightness according to the image compensation data.

It can be understood that, in the image processing system provided by the embodiment of the application, the target image data and the compensation data of the target image data are obtained; compensating the target image data based on the compensation data to obtain image compensation data, wherein the image compensation data is used for enabling a screen to display an image with uniform brightness; and outputting the image compensation data. Since the target image data can be compensated, image compensation data which can be used for making the screen display brightness uniform image is obtained; further, when the screen displays an image based on the image compensation data, an image with uniform brightness can be displayed; thus, the problem of uneven screen display brightness in the related art can be solved.

Based on the image processing method provided by the embodiment of the present application, the embodiment of the present application further provides a processing chip, where the processing chip may include a memory, and the memory stores a program or an instruction, and the program or the instruction implement the steps of the image processing method provided by the embodiment of the present application when executed.

In the embodiment of the application, the processing chip can be a display driving chip, a single display chip (also called an independent display card), an integrated display card and the like.

In the image processing method according to the above embodiment of the present application, a certain storage space is required for storing the acquired data, the compensation standard data, etc., and the memory space of the display driving chip and the integrated graphics card is relatively small. If the related module for implementing the image processing method is disposed in the display driving chip or the integrated display card, the storage requirement of the image processing method may not be satisfied, and thus the compensation of the target image data may not be implemented, or the compensation effect may be not ideal. Thus, the processing chip may preferably be a single-display chip, by which the image processing method in the above-described embodiment of the present application is performed.

It can be understood that the processing chip provided by the embodiment of the application obtains the target image data and the compensation data of the target image data; compensating the target image data based on the compensation data to obtain image compensation data, wherein the image compensation data is used for enabling a screen to display an image with uniform brightness; and outputting the image compensation data. Since the target image data can be compensated, image compensation data which can be used for making the screen display brightness uniform image is obtained; further, when the screen displays an image based on the image compensation data, an image with uniform brightness can be displayed; thus, the problem of uneven screen display brightness in the related art can be solved.

In addition, by setting the processing chip to be a single-display chip, the power consumption can be further reduced. Taking the display driving chip as an example, in practical application, the display driving chip generally adopts a 40nm process, and the process adopted by the single display chip is generally smaller than that adopted by the display driving chip, for example, adopts a 6nm process, or even smaller. Thus, the image processing method is executed by the single-display chip, and power consumption can be greatly reduced.

In the embodiment of the application, the single-display chip can also perform frame inserting processing according to the acquired frame rate information, as shown in fig. 5. Specifically, whether frame insertion is needed or not can be determined based on the frame rate information and the current application scene, and if so, frame insertion processing is performed. For example, the current frame rate is low, and the current frame rate of the screen needs to be higher fluency (such as game interface), so that the frame inserting process can be performed. It can be understood that by performing the frame interpolation processing, the dynamic picture display effect can be enhanced.

As shown in fig. 5, the single-display chip has at least two functions, namely, acquiring target data, wherein the target data comprises target image data and first display information, and generating compensation data according to the first display information by the single-display chip so as to compensate the target image data in the target data and obtain image compensation data. On the other hand, the single display chip judges whether to insert frames according to the frame rate information in the target data, and when the frames are needed to be inserted, the frame inserting process is carried out.

Based on the image processing method provided by the embodiment of the application, the embodiment of the application also provides electronic equipment, which comprises the processing chip provided by the embodiment.

More specifically, the electronic device includes a single-display chip, and the above-described image processing method is performed by the single-display chip.

In the case where the electronic device includes the single display chip, in one embodiment, as shown in fig. 6, the electronic device further includes a CPU and a screen having a display driving chip. The single display chip acquires target image data, gray-scale information of a display screen, display brightness level information, frame rate information, and the like from the CPU, and also acquires related data (not shown in the figure) from a clock and a temperature sensor of the electronic device. That is, target image data and first display information are acquired, wherein the target data includes the target image data and the first display information. And then the single display chip calculates to obtain image compensation data and outputs the image compensation data to the display driving chip. The internal computing logic of the single-chip in fig. 6 may refer to the foregoing and will not be described in detail herein.

In addition to the single-display chip, the CPU, and the screen having the display driving chip, the electronic apparatus may further include a power management chip (PowerManagementIC, PMIC) that may be used to manage power supplied from the power source to the single-display chip, the CPU, the display driving chip, the screen, and the like.
