Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

Referring to fig. 3, fig. 3 is a schematic flowchart of an image processing method according to an embodiment of the application. The image processing method can be applied to the display screen and used for improving the color depth of the display screen by increasing the image frame rate of the target image.

As shown in fig. 3, the image processing method specifically includes steps S301 to S305.

S301, acquiring an initial image frame rate of a display screen for displaying a target image under an initial color depth.

Specifically, the electronic device obtains an initial image frame rate of a display screen of the electronic device for displaying a target image under an initial color depth through a technical index parameter interface of the electronic device. In addition, the user can obtain the initial image frame rate of the display screen of the electronic device for displaying the target image at the initial color depth by referring to the factory setting specification of the electronic device.

It should be noted that, the specific manner of obtaining the initial image frame rate of the display screen for displaying the target image at the initial color depth is not limited herein.

The user may open a technical index parameter interface in the electronic device to which the display screen belongs by means of manual operation, voice input or the like, and query a parameter value of an initial image frame rate in the technical index parameter interface, so as to obtain the initial image frame rate at which the display screen of the electronic device can display an image, where the electronic device may be an AR glasses, a VR glasses, an intelligent robot or the like.

The user may open a technical index parameter interface in the electronic device by manual operations, such as manual clicking, manual touch, and the like, where the technical index parameter interface is displayed on the display screen, and the user may query an initial image frame rate of an image that may be displayed on the display screen through the technical index parameter interface displayed on the display screen. In addition, the user can also input through voice, for example, the user sends out a voice instruction: if the image frame rate is to be queried, the electronic equipment automatically pops up the technical index parameter interface on the display screen of the electronic equipment after receiving the voice command of the user, the user can query the initial image frame rate of the image to be 4hz or 8hz or other suitable frame rate values on the technical index parameter interface, and then the initial image frame rate of the display screen for displaying the target image at the initial color depth to be 4hz or 8hz or other suitable frame rate values are obtained.

It should be noted that the initial color depth and the initial image frame rate of the display screen are technical index parameters that have been determined when the electronic device leaves the factory.

S302, determining the target color depth corresponding to the display screen.

For example, the target color depth corresponding to the display screen may be determined by performing a color depth processing operation on the display screen according to the color depth processing operation.

Illustratively, a color depth editing operation is performed on the display screen, wherein the color depth editing operation can be at least one of a voice command and a manual input, and a target color depth corresponding to the display screen is determined according to the color depth editing operation. More specifically, the manual input may be a manual click, a manual touch, or the like.

When the color depth of the display screen is required to be modified, the user receives the color depth editing operation of the display screen, and the user can execute the color depth editing operation in a voice command mode, a manual click mode, a manual touch mode and the like and determine the target color depth of the display screen according to the color depth editing operation.

For example, the initial color depth of the image that can be displayed by the display screen is 1bit, the picture display is rough, in order to improve the color depth of the display screen, the user receives a color depth editing operation that improves the color depth of the image that can be displayed by the display screen from 1bit to other bits, for example, to 4bit, 8bit or other suitable color depth. Taking the example that the color depth of the image is increased from 1bit to 4 bits, according to the color depth editing operation, the target color depth corresponding to the display screen is determined to be 4 bits.

It should be noted that, the modification to the color depth of the display screen may be to increase the color depth of the display screen or decrease the color depth of the display screen, so as to obtain the target color depth, which may be specifically set according to the specific situation, and is not limited herein. The embodiment of the application mainly describes the specific implementation step for improving the color depth of the display screen in the image processing method in detail, and of course, it can be understood that the specific implementation step for improving the color depth of the display screen can be similarly applied to reducing the color depth of the display screen.

S303, determining an image frame rate ratio according to the initial color depth and the target color depth.

Illustratively, the image frame rate ratio is determined by dividing the target color depth of the display screen by the initial color depth.

For example, if the target color depth is 4 bits and the initial color depth is 1bit, the image frame rate ratio is 4 by dividing the target color depth and the initial color depth of the display screen.

S304, determining a target image frame rate of matching the target color depth according to the image frame rate ratio and the initial image frame rate.

Specifically, the target image frame rate may be calculated from both the image frame rate ratio and the initial image frame rate.

Illustratively, the target image frame rate is obtained by multiplying the image frame rate ratio and the initial image frame rate according to the calculated image frame rate ratio and the initial image frame rate. For example, if the image frame rate ratio is 4 and the initial image frame rate is 4hz, the image frame rate ratio and the initial image frame rate are multiplied to obtain the target image frame rate of 16hz.

It should be noted that, the specific values of the image frame rate ratio and the initial image frame rate may be reasonably determined according to specific situations, which is not limited herein.

S305, controlling the display screen to display the target image at the target image frame rate under the initial color depth.

Specifically, when a target image is displayed on a display screen at a target image frame rate at an initial color depth, the target image includes at least one frame of sub-image, each of which is identical except that the second gray level information may be different.

In an embodiment, a display order of the at least one frame sub-image is determined, and the display screen is controlled to display the at least one frame sub-image at the target image frame rate at the initial color depth in accordance with the display order.

For example, if the target image frame rate is 16, the target image includes 16 sub-images, wherein the first gray information of the 16 target images may be different, but the picture contents of the 16 target images are the same except for the first gray information. Then, a display order of 16-frame sub-images needs to be determined, and the display screen is controlled to display the 16-frame sub-images at the target image frame rate under the initial color depth according to the display order.

Specifically, before the target image is displayed at the target image frame rate at the initial color depth, at least one frame of sub-images is ordered, for example, the target image includes 16 frames of sub-images, and the 16 frames of sub-images may be ordered to obtain the display order of the 16 frames of sub-images. In addition, when 16 sub-images are displayed in the display screen in sequence, the display sequence of each sub-image is recorded, the display sequence of the 16 sub-images is determined, and the display screen is controlled to display the target image at the target image frame rate under the initial color depth according to the display sequence.

It will be understood, of course, that the number of frames in which the target image includes sub-images may be appropriately set according to the specific circumstances, and that the 16-frame sub-images are used for exemplary purposes only and are not limited in any way to the number of sub-images.

It should be noted that, at least one sub-image in the target image is sequentially arranged according to the sequence, and the sequence of displaying a certain sub-image is not fixed, when each sub-image in the target image frame rate is displayed for the first time on the display screen, and the higher or lower bit image display effect is achieved, each sub-image can appear in any sequence, but after the second and third times. Otherwise, the display screen cannot completely display the target image with higher or lower bit color depth, and the picture of the target image with the target color depth seen by the user on the display screen of the electronic device can be in the conditions of intermittent or uneven color and the like, so that the watching experience of the user is reduced.

For example, if the initial color depth of the target image is 1bit and the target image frame rate is 16, the display screen displays the target image at the target image frame rate at the initial color depth, and the target image includes 16 sub-images, wherein each sub-image is identical except for the second gray level information. If the 16-frame 1-bit sub-images at the initial color depth are respectively marked as (a, B, C, D, E.,. P.), the display sequence of the 16-frame 1-bit sub-images at the initial color depth is sequentially: (a-1, B-2, C-3, d-4, e-5,..p-16), wherein a-1 represents a first display of sub-image a on the display screen, B-2 represents a second display of sub-image B on the display screen, and C-3, d-4, e-5,..p-16 represents a third, fourth, fifth, and sixteenth display of the corresponding sub-image in that order in the display screen. The display screen is sequentially and rapidly refreshed and displayed according to the display sequence (A-1, B-2, C-3, D-4, E-5, the first-order, P-16) of the 16-frame 1-bit sub-images so as to achieve the display effect of the 4-bit target image. It should be noted that the display sequence of the 16-frame 1-bit sub-images is as follows: (a-1, B-2, c-3, D-4, e-5,., P-16) is not solely fixed, and the display order of the 16-frame 1-bit sub-images may also be (B-1, D-2, c-3, a-4, e-5,., H-16), or (D-1, a-2, c-3, B-4, e-5, f-6,., P-16), or the like. That is, the display order of the 16-frame 1-bit sub-images may be any order, but once the display order of the 16-frame 1-bit sub-images is determined, the 16-frame 1-bit sub-images at the initial color depth are sequentially refreshed in the display screen in the display order after the 16-frame 1-bit sub-images are determined. It will be appreciated that the initial color depth of the target image of 1bit and the target image frame rate of 16 are merely exemplary illustrations of displaying the target image at the target color depth, and that the target image frame rate may be any other suitable value as appropriate.

According to the image processing method provided by the embodiment, the initial image frame rate of the target image displayed by the display screen under the initial color depth is obtained; when receiving the color depth editing operation on the display screen, determining the target color depth corresponding to the display screen according to the color depth editing operation; determining an image frame rate ratio according to the initial color depth and the target color depth; determining a target image frame rate of target color depth matching according to the image frame rate ratio and the initial image frame rate; the display screen is controlled to display the target image at the target image frame rate at the initial color depth. The image processing method determines a target image frame rate by the image frame rate ratio and the initial image frame rate, and displays a target image on a display screen at the target image frame rate. On the premise of not changing the technical index parameters of the electronic equipment, the color depth of the display screen is increased, the hardware technical level of the display screen of the existing electronic equipment is broken through, and the fineness of the picture is improved.

Referring to fig. 4, fig. 4 is a schematic flowchart of another image processing method according to an embodiment of the present application. As shown in fig. 4, the image processing method specifically includes steps S401 to S404.

S401, controlling the display screen to display the target image at the target image frame rate under the initial color depth.

Specifically, the number of frames of sub-images in the target image at the target image frame rate is determined according to the target image frame rate, wherein the target image includes at least one frame of sub-images, each frame of sub-image being identical except for the second gray level information.

In an exemplary embodiment, a display order of the at least one frame sub-image is determined, and the display screen is controlled to display the at least one frame sub-image at the target image frame rate at the initial color depth in accordance with the display order.

S402, determining first gray scale information.

Specifically, the first gradation information is gradation information of a display target image at a target color depth.

In some embodiments, the gray information of the target image at the target color depth may be extracted by a programming language in the embedded software, such as c language, c++, etc., to obtain the first gray information, where the target image at the target color depth may be obtained by a User Interface (UI) or other image design tools, and after obtaining the target image at the target color depth, the gray information of the target image at the target color depth may be extracted by the programming language, c language, c++, etc.

For example, if a target image at a target color depth is obtained according to a User Interface design (UI) or other image design tools, where the target color depth is 4 bits, the target image at the target color depth is associated with embedded software, and gray information is extracted according to a programming language, such as c language, c++, and the like, to obtain first gray information, where the first gray information may be represented in the form of an array, specifically [7,2,4,6, a.4 ], where each number in the array represents each first gray value in the target image.

S403, determining second gray scale information of the display target image under the initial color depth according to the first gray scale information.

For example, after determining the first gray information of the target image at the target color depth, the second gray information of the target image at the initial color depth may be obtained according to the first gray information.

In some embodiments, each first gray value of the first gray information and a first position corresponding to each first gray value may be acquired; determining a second gray value and a second position of each first gray value under the initial color depth according to each first gray value and a first position corresponding to each first gray value; and determining second gray information according to the second gray value and the second position corresponding to each first gray value.

For example, if the first gray information of the target image at the target color depth is represented in the form of an array, where each number in the array represents a first gray value, each number represents a first position corresponding to the first gray value, where the length of the array is determined by the number of the first gray values of the target image at the specific target color depth, which may be 200×200, or 640×480, or the like, where if the first gray information of the target image at the target color depth is represented in the form of an array with 640×480 numbers, that is, 307200, where the length of the array is 307200, which represents 640 gray values on the long side and 480 gray values on the short side of the target image, the gray value of the entire target image is 307200.

For example, for each first gray value calibration position in the target image under the target color depth, that is, the first position corresponding to the first gray value, where the first position corresponding to each first gray value may be represented in a coordinate form, for example, a center point of the target image under the target color depth may be taken as an origin, a horizontal direction of the center point may be rightward taken as a positive direction of an x-axis, a vertical direction of the center point may be upward taken as a positive direction of a y-axis, or a lower left corner of the target image under the target color depth may be taken as an origin, a horizontal direction of a lower left corner may be rightward taken as a positive direction of the x-axis, a vertical direction of a lower left corner may be upward taken as a positive direction of the y-axis, and specific origin of coordinates and positive directions of the x-axis and the y-axis may be reasonably set according to circumstances, without limitation.

It should be noted that, the use of an array to represent the first gray information, and each number in the array represents the first gray value and the representation of the first position for each gray value pair in the form of coordinates is merely illustrative for easy understanding, and it should be understood that the first gray information, the first gray value, and the first position may be represented in any other reasonable representation, and are not limited herein.

For example, the first gray information may be extracted according to a programming language in the embedded software, and each first gray value of the first gray information and a first position corresponding to each first gray value may be determined. Assuming that the first gradation information of the target image at the acquired target color depth is [7,2,4,6,..4 ], the lower left corner of the target image is taken as the origin, the horizontal direction of the lower left corner is rightward taken as the positive direction of the x-axis, and the vertical direction of the lower left corner is upward taken as the positive direction of the y-axis, each first gradation value of the first gradation information is 7,2,4,6,..4, respectively, and the first positions corresponding to each first gradation value of the first gradation information are recorded as (1, 1), (1, 2), (1, 3), (1, 4), (100, 150) in order. It should be noted that, in the present application, the same coordinates are used to respectively represent the first position of each first gray value and the second position of each second gray value, which are not described herein.

Illustratively, taking an initial color depth of 1bit and an initial image frame rate of 4hz as an example of the obtained target image in the display screen, the target is the display effect of the target image under the target color depth of 4 bits in the display screen. Then the display effect of the target image at the target color depth of 4 bits can be achieved by calculating the sub-image that requires 16 frames of initial color depth of 1 bit. The gray value of each sub-image of the 16 frames with the initial color depth of 1bit is then further processed.

Specifically, a second gray value and a second position of each first gray value at the initial color depth are determined according to each first gray value and a first position corresponding to each first gray value. For example, if the first gray value in the first gray information of the target image at the target color depth is 7, the first position corresponding to the first gray value is (1, 1), the second gray value of the 7-frame 1-bit sub-image in the 16-frame 1-bit sub-image is 1, the second gray value of the remaining 9-frame 1-bit sub-images is 0, the second position where the second gray value is located corresponds to the first position, the second position is also (1, 1), and the coordinate information of each of the 16-frame 1-bit sub-images is the position where (1, 1) is located. Then, a first gray value 2 in the first gray information is extracted, a first position (1, 2) corresponding to the first gray value 2 is determined, a second gray value and a second position of a target image of 1bit of each frame in the 16-frame 1bit sub-images are determined according to the first gray value 2 and the first position (1, 2), namely, the second gray value of any 2-frame 1bit sub-image in the 16-frame 1bit sub-images is 1, and the second gray value of the rest 14-frame 1bit sub-images is 0. And similarly, sequentially extracting the remaining first gray values and the first positions corresponding to the first gray values in the first gray information, and determining the second gray values and the second positions of the first gray values under the initial color depth according to the first gray values and the first positions corresponding to the first gray values until all the second gray values and the second positions in the second gray information are determined according to all the first gray values and the first positions corresponding to the first gray values in the first gray information.

S404, displaying the target image according to the second gray level information.

For example, after the second gray level information is determined according to the first gray level information, at least one sub-image corresponding to the determined second gray level information is displayed in the display screen at the target image frame rate under the initial color depth.

For example, if the initial color depth of the target image in the display screen is 1bit and the initial image frame rate is 4hz, 16 frames of sub-images with the initial color depth of 1bit are required to achieve the display effect of the target image at the target color depth of 4 bits in the display screen. After determining the second gray information of the sub-image with the initial color depth of 1bit in 16 frames according to the first gray information of the target image with the target color depth of 4 bits, refreshing the sub-image with the initial color depth of 1bit in 16 frames on a display screen in sequence, obtaining the display effect of the target image with the target color depth of 4 bits on the display screen, and referring to fig. 6, a specific display effect diagram of the target image with the target color depth of 1bit reaching the target image with the color depth of 4 bits can be referred to.

It should be noted that fig. 6 shows a schematic display effect diagram of 8-frame sub-images with 1bit color depth, and according to the above image frame rate ratio and the initial image frame rate, the actual 1-bit sub-image should be 16 frames to achieve the display effect of the 4-bit color depth target image.

The above embodiment provides another image processing method, after determining the target image frame rate at which the target color depth matches, determining first gray information, where the first gray information is gray information of the target image displayed at the target color depth; determining second gray information of the display target image under the initial color depth according to the first gray information; and displaying the target image according to the second gray level information. In the image processing method, at least one frame sub-image at a corresponding frame rate is determined according to a target image frame rate. And determining second gray level information of at least one frame of sub-image through the first gray level information, and displaying at least one frame of sub-image on the display screen according to the display sequence on the premise of determining the display sequence of at least one frame of sub-image in the display screen, so that the color depth of the display screen is increased, the display effect of the target image under the target color depth can be achieved, and the visual experience of a user is improved.

Specifically, taking a display screen in an AR glasses device as an example, an image processing method of the display screen of the AR glasses device is specifically analyzed. Referring to fig. 5, fig. 5 is a schematic flowchart of an image processing method of a display screen of an AR glasses device according to an embodiment of the present application. Specifically, the method comprises steps S501 to S505.

S501, acquiring an initial image frame rate of a target image.

By way of example, the user may obtain an initial image frame rate at which the display screen displays the target image at the initial color depth by querying a technical index parameter field in the specification of the display screen of the AR glasses device, and may also obtain the initial color depth of the target image. Assume that the initial image frame rate obtained by the user is 1hz, and the initial color depth of the obtained target image is 4 bits. Of course, any other suitable values for the initial image frame rate and the initial color depth are possible, and are not limited in this regard. In addition, the user can also obtain the initial image frame rate of the display screen of the AR glasses device by clicking, touching or voice calling the AR glasses device and opening a technical index parameter page of the AR glasses device.

S502, determining the target color depth.

For example, the user may obtain the target color depth corresponding to the display screen of the AR glasses device according to the color depth editing operation, and to improve the color depth of the display screen of the AR glasses device, it may be assumed that the color depth of the display screen of the AR glasses device is improved to 8 bits.

It will be understood, of course, that the color depth of the display screen of the AR glasses device may be increased to any other suitable color depth value such as12 bit, 16bit, etc.

S503, determining an image frame rate ratio.

Specifically, the image frame rate ratio may be determined from an initial color depth and a target color depth of a display screen of the AR glasses apparatus.

For example, if the initial color depth of the display screen of the AR glasses apparatus is 4 bits and the target color depth is 8 bits, the image frame rate ratio is 2 by dividing the target color depth and the initial color depth.

S504, determining a target image frame rate.

Specifically, a target image frame rate of the display screen of the AR glasses device is determined from an initial image frame rate to image frame rate ratio of the display screen of the AR glasses device.

Illustratively, the target image frame rate may be obtained by multiplying the initial image frame rate and the image frame rate ratio of the display screen of the AR glasses device. If the initial image frame rate of the display screen of the AR glasses device is 1hz and the image frame rate ratio is 2, the target image frame rate of the display screen of the AR glasses device is 2hz according to the product result of the initial image frame rate and the image frame rate ratio.

S505, displaying the target image on a display screen.

For example, the first gray information of the target image displayed on the display screen of the AR glasses apparatus is determined, where the first gray information is the gray information of the target image displayed at the target color depth, and may be the gray information of the target image displayed at the target color depth of 8 bits. And determining second gray information of the display target image under the initial color depth according to the first gray information, wherein the initial color depth can be 4bit initial color depth, namely determining second gray information of the display target image when the initial color depth is 4bit according to the first gray information of the display target image when the target color depth is 8 bit.

Specifically, an image with a target color depth of 8 bits can be obtained through a UI, the image with the target color depth of 8 bits is associated with embedded software, first gray information of the image with the target color depth of 8 bits is extracted through proper programming languages such as c language, java and the like in the embedded software, and second gray information is determined according to the extracted first gray information.

In some embodiments, each first gray value of the first gray information and a first position corresponding to each first gray value are acquired; determining a second position of each first gray value under the initial color depth according to the first position corresponding to each first gray value; carrying out the binary processing on each first gray value to obtain an initial gray value corresponding to each first gray value; determining a target gray value of each initial gray value under the initial color depth according to the target image frame rate; and carrying out the system processing on each target gray value to obtain the second gray value corresponding to each target gray value. And determining second gray information according to the second gray value and the second position corresponding to each first gray value.

It should be noted that, the above-mentioned method for performing the binary processing on each of the first gray values to obtain an initial gray value and performing the binary processing on each of the target gray values to obtain a second gray value may be any suitable binary processing method such as binary processing, decimal processing, etc., and a suitable binary processing method may be selected according to the specific situation.

For example, if the frame rate of the target image is 2, the target image includes 2 sub-images, and if the first gray value in the first gray information of the image extracted by the embedded software and having the target color depth of 8 bits is 77, the first position corresponding to the first gray value is recorded, and if the first position is (3, 4), the second position of the first gray value at the initial color depth, that is, the second position of the first gray value at the initial color depth is also (3, 4) according to the first position (3, 4) corresponding to the first gray value. Binary processing is carried out on the first gray value 77, so that an initial gray value corresponding to the first gray value 77 is 01001101, bit0 to bit3 and bit4 to bit7 in the initial gray value are respectively extracted, and a target gray value corresponding to the initial gray value 01001101 is 1101 and 0100 respectively. The target gray values corresponding to the first gray value are 1101 and 0100, respectively. Decimal processing is performed on the two target gray values, so that second gray values 13 and 4 corresponding to the two target gray values 1101 and 0100 are obtained respectively. The two second gray values 13 and 4 are respectively used as the second gray values of the corresponding second positions (3, 4) of the sub-image with the initial color depth of 4 bits of 2 frames. And performing the same treatment on other first gray values in the first gray information of the image with the target color depth of 8 bits until the second gray values of the sub-images with the initial color depth of 4 bits of 2 frames are all set according to the first gray values, ending the setting of the second gray values, and determining the second gray information of the sub-images with the initial color depth of 4 bits of 2 frames.

Illustratively, after determining the second gray scale information, determining a display order of at least one frame sub-image at the target image frame rate; controlling the display screen to display images at the target image frame rate under the initial color depth according to the display sequence, for example, after the second gray level information of the sub-images with the initial color depth of 4 bits of 2 frames is determined, determining the sequence of the sub-images with the initial color depth of 4 bits of 2 frames is needed, and assuming that the sub-images with the initial color depth of 4 bits of 2 frames are respectively a sub-image A and a sub-image B, wherein only the second gray level information of the sub-images A and B may be different. The display order of the sub-images with the initial color depth of 4 bits of 2 frames can be A and B; the display sequence of the sub-images with the initial color depth of 4 bits can be set arbitrarily, but when the display sequence is determined, the display sequence cannot be changed when the sub-images are displayed on the display screen of the AR glasses device in a rapid cycle mode, so that the display effect of the 8bit target color depth can be achieved, otherwise, color non-uniformity or intermittent picture display effect of the expected 8bit target color depth cannot be achieved on the display screen of the AR glasses device, and a specific display effect diagram of the target image with the color depth of 4 bits reaching the 8bit color depth can be referred to as fig. 7.

In the image processing method for the display screen of the AR glasses apparatus provided in the above embodiment, the target image frame rate is further obtained according to the image frame rate ratio and the initial image frame rate by determining the initial image frame rate and the initial color depth of the target image displayable by the display screen of the AR glasses apparatus, determining the target color depth displayable by the display screen, determining the image frame rate ratio according to the target color depth and the initial color depth. And finally, determining second gray level information of each sub-image of the target image at the target image frame rate according to the first gray level information. And displaying the sub-image after the determination of the second gray level information in the display screen at the target image frame rate. Under the condition that the factory color depth parameter value of the display screen of the AR glasses device is not changed, the color depth of the display screen of the AR glasses device is greatly increased.
