The following describes how the embodiments of the present application perform image processing by using detailed embodiments.

Fig. 6 is a flowchart illustrating an image processing method according to an embodiment of the present application. As shown in fig. 6, the processor 254 in the display device 200 is configured to perform the following steps:

in S601, a display duration of the display from the current power-on start to the current time is determined.

In S602, a first average image level value of the image displayed within the display period is acquired.

In practical applications, after the display device 200 is powered on, the display 275 will send display data to the processor 254 in real time, wherein the display data includes: the display duration and an Average Picture Level (APL) value corresponding to the current display duration. It should be noted that, as to a manner of obtaining the display data, the embodiment of the present application is not specifically limited, and in one implementation, the display data of each frame of image may be obtained once per frame of image, or the display data within the interval duration may also be obtained once at intervals of a preset duration.

Accordingly, the processor 254 determines the display duration of the current power-on time from the current time and the first average image level value corresponding to the display duration in real time according to the display data. In practical applications, the embodiment of the present application is not particularly limited to a specific scheme for obtaining the first average image level value of the image displayed within the display duration.

In some embodiments, the first average image level value of the image displayed within the display duration may be an APL value corresponding to the current time, that is, an APL value corresponding to the ending time of the display duration is determined, and the first average image level value of the image displayed within the display duration.

In other embodiments, the first average image level value of the image displayed in the display duration may also be an average value of corresponding average image level values in a plurality of time periods in the display duration. Specifically, in one implementation, second average image level values of the images displayed in the display duration within a plurality of preset time periods may be obtained, and then the first average image level value of the image displayed in the display duration may be determined according to the second average image level value of each image. For example, in the display duration, with the duration of each frame of image as a preset time period, a second average image level value corresponding to each frame of image in the display duration may be obtained, and then the average value of the second average image level values of the multiple frames of images in the display duration is determined as the first average image level value of the image displayed in the display duration, and how to obtain the APL value of each frame of image is shown in the following embodiments.

According to the scheme, the first average image level value in the display duration is determined according to the real-time APL value of each frame of image in the display duration, so that the accuracy of the first average image level value can be improved, the accuracy of image adjustment is improved, and the eye protection effect is improved to the maximum extent.

In S603, the primary color data corresponding to the current time of the display is determined according to the display duration and the first average image level value.

Wherein the primary color data is used to adjust a primary color ratio of the display, the primary color ratio including at least one of a red color ratio, a green color ratio, and a blue color ratio.

In practical application, the higher the APL value of the image is, the more easily the visual fatigue of the user is caused, and the lower the primary color proportion of the image is, the lower the light proportion received by human eyes can be made, thereby achieving the purpose of improving the visual fatigue.

For a specific scheme of determining the primary color data according to the first average image level value, the embodiment of the present application is not particularly limited, for example, in an implementation, the primary color data corresponding to the current display duration may be determined according to a corresponding relationship between the first average image level value and the primary color data, where the corresponding relationship between the first average image level value and the primary color data may be determined according to the historical image display duration and the primary color data. As to other ways of determining the primary color data, shown in the subsequent embodiments.

In S604, the display is controlled to display an image according to the primary color data.

It should be noted that, after the display device is powered on and displays an image, the processor 254 periodically executes the above steps, determines the primary color data at the current time according to the average image level value by acquiring the display duration after power-on and the average image level value in the display duration in real time, and controls the display device to display an image according to the primary color data, thereby achieving the purpose of adjusting the display effect of the display device 275 in real time, and finally achieving the eye protection effect.

In the embodiment of the application, the display duration of the display from the current power-on start to the current time is determined through the display equipment; then, a first average image level value of the image displayed within the display duration is obtained; and determining the primary color data corresponding to the current moment of the display according to the display duration and the first average image level value. And finally, controlling the display to display the image according to the primary color data. In the scheme, the primary color proportion of the display can be adjusted in real time based on the current display time of the display and the average image level value of the image, the display effect of the display can be accurately adjusted, and therefore the eye protection effect is achieved.

In some scenarios, when the display duration is longer, the data processing pressure is relatively higher by acquiring the display data of the display duration, so that the display data in the sub-display duration can be acquired once every sub-display duration, and then the display data of the current display duration is acquired according to the display data of a plurality of sub-display durations in the display duration. Next, on the basis of the above-described embodiment, the present solution is described in more detail with reference to fig. 7.

Fig. 7 is a schematic flowchart of an image processing method according to an embodiment of the present disclosure. In practical applications, the display duration includes a plurality of sub-display durations, and after the display device 200 is powered on and started each time, the display 275 acquires a third average level value corresponding to each sub-display duration of the image in real time.

Optionally, the display device 200 further includes a first memory 2601 and a second memory 2602, wherein the first memory 2601 is configured to store a third average image level value corresponding to each sub-display duration, and the second memory 2602 is configured to store primary color data within the display duration. The following describes in detail the manner of obtaining and storing the third average image level value corresponding to the sub-display duration with reference to the specific embodiment:

in practical applications, since the average image level value of each frame of the image may change, in order to save storage space, a plurality of storage entities may be disposed in the first memory 2601, and the plurality of storage entities store the APL values corresponding to the plurality of sub-display durations through a loop feedback manner.

Optionally, for the sub-display durations with the same time length, the third average image level value of the image displayed in the sub-display duration is stored in the same storage entity; and/or, for the sub-display periods with different time lengths, the third average image level values of the images displayed in different sub-display periods are stored in different storage entities.

For easy understanding, please refer to fig. 8, and fig. 8 is a schematic diagram illustrating a process of obtaining and storing an average image level value according to an embodiment of the present application. As shown in fig. 6, the first memory 2601 includes M storage entities therein: storage entity 1, storage entity 2. It should be understood that the number of storage entities of different models of display devices is different, and therefore, the embodiment of the present application is not particularly limited to the value of M. In addition, each storage entity may store a plurality of APL values, and the maximum storage quantity of the APL values stored in each storage entity may be the same or different, and the embodiment of the present application is not limited thereto. It should be noted that, in the embodiment of the present application, it is exemplified that the maximum storage quantities in the plurality of storage entities are the same, and N APL values may be stored, but not limited thereto, where N is an integer greater than or equal to 1.

Specifically, taking each sub-display duration t as an example, obtaining the third average level value corresponding to each sub-display duration t includes the following steps:

from the moment when the display device 200 is powered on and displays images, acquiring the APL value of each frame of image displayed in the display 275 in real time, storing the APL value of each frame of image into the storage entity 1, and taking the average value of the APL values of the frames of images in the storage entity 1 every time t is timed out

Emptying data in the storage entity 1, and repeating the steps to obtain the average value of the next time t

I.e. t ₁ 、t ₂ ...t _n The third average level values corresponding to the sub-display durations are respectively as follows:

further, each time the APL value at time t is obtained, the APL value is sent to the next storage entity 2 for storage, that is, the third average level value stored in the storage entity 2 is:

when the number of the third average level values stored in the storage entity 2 reaches N (i.e., when N is N), the storage entity is again paired with NAveraging the N third average level values stored in the entity 2, storing the obtained result in the next storage entity, clearing the third average level value stored in the storage entity 2, and storing the APL value corresponding to the next time t again.

Taking the secondary class, taking the example that the display device 200 is still provided with M storage entities, and each storage entity can store N data, the first memory 2601 can cumulatively store N data ^M-1 APL data at time t, i.e. storing N ^M-1 And a third average level value corresponding to each sub-display time length.

The following describes the image processing method provided in the embodiments of the present application in detail with reference to specific steps. As shown in fig. 7, the processor 254 in the display device 200 is configured to perform the following steps:

in S611, a third average image level value of the images displayed within the sub-display period is acquired.

In S612, the first average image level value of the image displayed within the display duration is determined according to the third average image level value corresponding to the plurality of sub-display durations.

In the above steps, after the display device 200 is powered on and displays an image, the processor 254 obtains, in real time, the display duration corresponding to the current time and the third average image level value of the image displayed in the sub-display duration, and determines the first average image level value of the image displayed in the display duration according to the corresponding relationship between the display duration and the sub-display duration.

For example, if the current display duration is determined to be t ₁ Then t is retrieved from the first memory 2601 ₁ Corresponding third average image level value

And determine

For the first average image level value of the image displayed within the display time period, similarly, if it is determined that the current display time period is (M-1) t, it is obtained from the first memory 2601Taking the third average image level value corresponding to (M-1) t

And determine

Is the first average picture level value of the picture displayed within the display duration.

In S613, a first coefficient corresponding to the display duration is determined.

Wherein, the first coefficient is a coefficient of a primary color corresponding to different display durations when the average image level value of the displayed image is the maximum average image level value of the display 275.

In practical applications, the first coefficient may be determined according to a corresponding relationship between the display duration and the first coefficient. The corresponding relation between the display duration and the first coefficient is determined according to the historical display duration and the coefficient of the primary color corresponding to each display duration.

It should be noted that the maximum average image level value of the display 275 is the maximum value of the signal brightness represented by the conventional chip, and the maximum average image level values of different chips are different in this embodiment, which is exemplified by that the maximum average image level value of the display 275 is 255, but not limited thereto.

In one implementation, the display duration T is used as a preset interval, and the primary color proportion of the display 275 is adjusted by adjusting the value of the first coefficient to obtain the first coefficient corresponding to each display duration T under the condition that the display 275 has the maximum average image level value, so as to obtain the corresponding relationship between the display duration and the first coefficient as shown in the following table:

t (display duration)	a (first coefficient)
		[0，T)	a ₀ ＝1
[T，2T)	a ₁
		[2T，3T)	a ₂
...	...
		[(n-1)T，nT)	a _n-1
≥nT	a _n

In practical application, when dynamic debugging is triggered by using a fixed time interval T, the dynamic debugging is not triggered when T belongs to the [0, T) interval. Through this scheme, on the one hand, can first reduce because too frequent dynamic debugging brings big image delay, in addition, can also avoid bringing unnecessary image scintillation to promote user experience.

In some embodiments, according to the correspondence table between the display duration and the first coefficient, a mapping relationship diagram between the display duration and the first coefficient as shown in fig. 9 can be obtained. In this step, according to the relationship between the current display duration and the display duration, the first coefficient corresponding to the current display duration can be obtained.

In S614, a second coefficient is determined according to the first average image level value.

It should be noted that the second coefficient is a ratio of the first average image level value to the maximum average image level value of the display. Illustratively, taking the second coefficient β and the maximum average image level value of the display 275 as 255 as an example, the value of β can be determined by the following formula:

wherein,

is the first average picture level value for the current display duration.

In S615, the primary color data corresponding to the display is determined according to the first coefficient and the second coefficient.

In practical application, due to visual fatigue and image display

In direct proportion, i.e. over a fixed time

The higher the value is, the more easily visual fatigue is caused, and then the primary color ratio needs to be greatly reduced to improve the visual fatigue, conversely, when the value is higher

The lower the value, the lower the reduction of the primary color ratio needs to be, and therefore, the adjustment of the primary color ratio is inversely related to the value of β. It should be noted that, for a specific corresponding relationship between the adjustment amplitude of the primary color proportion and β, the embodiment of the present application is not limited specifically, for example, the adjustment amplitude of the primary color proportion and β may be linearly negative correlation or non-linearly negative correlation, and for convenience of understanding, the embodiment of the present application takes the adjustment amplitude of the primary color proportion and β as an example, which are linearly negative correlation.

Specifically, the step S615 may include the following steps:

(1) and determining a primary color coefficient corresponding to the current display time of the display according to the first coefficient and the second coefficient.

Wherein the primary color coefficient is a product of a first coefficient and a second coefficient, and the primary color coefficient is used for adjusting the primary color scale of the display 275, i.e., an adjustment magnitude representing the primary color scale.

Illustratively, by representing the primary coefficients of the display 275 corresponding to the current time, by γ, it can be derived: γ ═ a ═ β.

(2) Based on the primary coefficients and the raw primary data of the display 275, the primary data corresponding to the current time instant of the display 275 is determined.

Based on the above, the original primary color data of the display 275 is S with the current primary color data being S ₀ And when β is 1, S is a _n-1 *S ₀ When β is 0, S is a _n-2 *S ₀ For example, a correspondence map between the primary color coefficients and the second coefficients as shown in fig. 10 may be derived.

Further, from fig. 10, the following formula for calculating the primary color data as S can be obtained:

s＝[a _n-2 -β(a _n-2 -a _n-1 )]*S ₀

in S616, the display is controlled to display an image according to the primary color data.

In some embodiments, S616 may specifically include the following steps:

(1) adjusting an original gamma curve of the display according to the primary color data and the original primary color data of the display to obtain the gamma curve of the display at the current moment;

(2) and controlling the display to display the image according to the gamma curve.

It should be noted that, after the primary color data corresponding to the display duration is obtained, the primary color data may also be stored in the second memory 2602, so that after the display device 200 is powered on to display an image next time, the display 275 is controlled to display the image according to the primary color data corresponding to the display duration stored in the second memory 2602.
