The following describes a software environment to which the image processing method provided by the embodiment of the present invention is applied, by taking an android operating system as an example.
Fig. 1 is a schematic diagram of an architecture of a possible android operating system according to an embodiment of the present invention. In fig. 1, the architecture of the android operating system includes 4 layers, which are respectively: an application layer, an application framework layer, a system runtime layer, and a kernel layer (specifically, a Linux kernel layer).
The application program layer comprises various application programs (including system application programs and third-party application programs) in an android operating system.
The application framework layer is a framework of the application, and a developer can develop some applications based on the application framework layer under the condition of complying with the development principle of the framework of the application. For example, applications such as a system setup application, a system chat application, and a system camera application. And the third-party setting application, the third-party camera application, the third-party chatting application and other application programs.
The system runtime layer includes libraries (also called system libraries) and android operating system runtime environments.

The kernel layer is an operating system layer of an android operating system and belongs to the bottommost layer of an android operating system software layer. The kernel layer provides kernel system services and hardware-related drivers for the android operating system based on the Linux kernel.
Taking an android operating system as an example, in the embodiment of the present invention, a developer may develop a software program for implementing the image processing method provided in the embodiment of the present invention based on the system architecture of the android operating system shown in fig. 1, so that the image processing method may operate based on the android operating system shown in fig. 1. Namely, the processor or the terminal device can implement the image processing method provided by the embodiment of the invention by running the software program in the android operating system.
The following describes the image processing method provided by the embodiment of the present invention in detail with reference to the flowchart of the image processing method shown in fig. 2. Wherein, although the logical order of the image processing methods provided by embodiments of the present invention is shown in a method flow diagram, in some cases, the steps shown or described may be performed in an order different than here. For example, the image processing method illustrated in fig. 2 may include S201 to S205:
s201, the terminal device collects a first image through a first camera component.
The terminal device provided by the embodiment of the invention comprises a first camera component and a second camera component, wherein the first camera component comprises a color chip, and the color chip can transmit light rays of all colors.
It can be understood that, in the embodiment of the present invention, the color chart is fixedly disposed in the first camera assembly, that is, the color chart and the lens in the first camera assembly are fixed. Namely, the relative position of the color card and the terminal equipment is fixed.
It should be noted that, lenses are included in both the first camera assembly and the second camera assembly to support the terminal device to capture images. For example, the lens in the second camera assembly is the main lens, and the lens in the first camera assembly is the auxiliary lens.
Specifically, the terminal device may capture an image (also referred to as a photograph or a picture) of the color chart through the first camera component, and capture an image of the actual needs of the user, such as an image containing some people or still things, through the second camera component.
It is emphasized that the terminal device can capture images through the first camera assembly and the second camera assembly respectively in the same light environment.
It can be understood that parameters such as the position and color temperature of the light source are different in different light environments. Thus, with the change of the light environment of the object, the color of the object, that is, the color of the image of the object, changes. For example, the higher the color temperature of a light source in a light environment, the more yellow the color of an image of an object in the light environment; the lower the color temperature of the light source in a light environment, the more blue the color of the image of the object in the light environment.
Optionally, the first camera assembly and the second camera assembly are located at different positions on the same exterior surface of the terminal device. Therefore, the view finding direction of the lens of the first camera component is consistent with that of the second camera component, and the terminal device can shoot images in the same light environment through the first camera component and the second camera component respectively.
For example, the first camera component and the second camera component may be disposed on a back side of the terminal device.
In addition, a person skilled in the relevant art may set the first camera component and the second camera component at two positions on the first outer surface of the terminal device, which are closer to each other, so as to capture images in the same light environment through the first camera component and the second camera component. For example, the second camera component is arranged at the upper left of the rear face of the terminal device, and the first camera component is arranged below the second camera component on the rear face.
Exemplarily, as shown in fig. 3, a schematic diagram of a position of a camera assembly on a terminal device is provided for an embodiment of the present invention. Wherein, the view shown in (a) in fig. 3 is a rear view of the terminal device, the view shown in (b) in fig. 3 is a side view (for example, a left view) of the terminal device, and the view of the front side where the screen of the corresponding terminal device is located is a front view of the terminal device. Specifically, the second camera assembly 31 is disposed at the upper left on the rear face of the terminal device, and the first camera assembly 32 is disposed below the second camera assembly 31 on the rear face.
Specifically, in the embodiment of the present invention, after the terminal device acquires the first image through the first camera component, the first image may be saved (i.e., the first image is captured and saved), for example, the first image is saved in a gallery application program of the terminal device.
It should be noted that the terminal device may perform the step of capturing the first image by the first camera assembly in the background. At this time, a shooting preview interface such as a view frame of the image captured by the first camera assembly may not be displayed on the screen of the terminal device, and the first image does not need to be displayed in a preview manner. It is understood that the terminal device has a camera application installed therein, and the user can trigger the terminal device to start and run the camera application, such as capturing an image or displaying a preview image on a screen. Specifically, when the terminal device runs the camera application, the terminal device may preview and display the image captured by the second camera component on the screen in real time, without previewing and displaying the image captured by the first camera component (i.e., the image of the color chip, such as the first image) in real time.
It should be noted that the terminal device may perform the step of capturing the first image by the first camera assembly in the background. At this time, a shooting preview interface such as a view frame of the image captured by the first camera assembly may not be displayed on the screen of the terminal device, and the first image does not need to be displayed in a preview manner.
Optionally, the terminal device may start to enable the first camera component and the second camera component when the camera application is started, so that the terminal device starts to capture the first image through the first camera component and starts to capture the image through the second camera component.
Optionally, the first camera assembly further includes a lens and a shielding component, and the lens, the shielding component and the color card are sequentially arranged along the first direction; the first direction is perpendicular to the first outer surface of the terminal device and far away from the first outer surface of the terminal device, and light entering the color card enters the lens through the shielding component. Wherein, the lens, the shielding component and the color card can be connected in sequence, such as adhesion.
Specifically, the light enters the lens of the first camera assembly through the color chip of the first camera assembly.
The color card is arranged in front of the lens in the first camera component, so that light rays entering the color card can enter the lens through the shielding component. Therefore, light can better enter the lens, excessive loss on a path from the color card to the lens can be avoided, and the image quality of the first image acquired by the first camera component is better.
Optionally, the second surface of the shielding member is opaque, and the second surface is not in contact with the lens and the color card in the first camera assembly. That is, the second surface is a surface of the blocking member other than the surface in contact with the lens (i.e., the auxiliary lens) and the color chart. Specifically, the shielding member may be a hollow cylindrical structure, and the second surface of the shielding member may be an outer surface and/or an inner surface of the cylindrical structure of the shielding member.
Specifically, under the condition that the second surface of the shielding component is the cylindrical outer surface, the shielding component is a sealing area between the color card and the auxiliary lens, so that light can be prevented from entering the auxiliary lens from an area outside the color card, namely, the light is prevented from entering the auxiliary lens from the shielding component.
The shielding member may be a black opaque material. The specific material of the opaque material may be determined according to actual use requirements, and this is not particularly limited in the embodiment of the present invention.
Optionally, the color chip is shaped like a hemisphere, and light enters the color chip from the outer surface of the color chip. I.e. light enters the auxiliary lens of the first camera component from the hemispherical outer surface of the color chip. The hemispherical color card can support the color card to enter more light rays, so that the auxiliary lens enters more light rays, and the quality of the first image collected by the first camera component of the subsequent terminal device is improved.
Illustratively, as shown in fig. 3 (b), the exterior of the first camera assembly 32 is a hemispherical color chip. Specifically, referring to fig. 3, as shown in fig. 4, a structural composition diagram of a camera module is shown. Fig. 4 shows the structure of the first camera assembly 32, and the first camera assembly 32 includes an auxiliary lens 41, a blocking member 42, and a color chart 43, and it is apparent that the color chart 43 has a hemispherical structure.
S202, the terminal device calculates calibration parameters according to the first parameters of the first image and the second parameters of the color chart.
The first parameter is used for indicating the color of the first image, the second parameter is used for indicating the color of the color chip, and the calibration parameter is used for calibrating the image acquired by the terminal device through the second camera assembly.
In embodiments of the present invention, the color chip may be a translucent component to support light entering (i.e., passing through) the color chip. Therefore, the terminal equipment can shoot the first image through the first camera component and know the color of the first image, namely, the first parameter of the first image is obtained.
Optionally, the material of the color chart may be glass, plastic, paper, a color filter, or the like, which may be determined according to actual use requirements, and this is not specifically limited in the embodiment of the present invention. For example, the color chip may be implemented by a translucent glass lens.
Optionally, the color chip is a gray and translucent component. That is, the color chart in the embodiment of the present invention may be a gray standard card.
It is to be understood that the color of the color chip is known and predetermined by the skilled artisan. I.e. the second parameter of the color chip is known.
A grey and translucent colour chip allows ambient light to enter the colour chip, since grey is transparent for all colours, i.e. grey is uniform for all colours projected.
It should be noted that a color has three characteristics, namely hue, lightness, and saturation. The three characteristics of color and their interrelation can be illustrated by using three-dimensional colors as an example.
The terminal device can record various colors through a color mode, namely, the various colors are expressed into a model in a digital form. Specifically, the Color mode may be classified into a red-green-blue (RGB) mode, a cyan-magenta-yellow-black (CMYK) mode, a hue-saturation-brightness (HSB) mode, a Lab Color mode, a Bitmap (Bitmap) mode, a gray scale (gray) mode, an index Color (index Color) mode, a two-tone (Duotone) mode, a multi-channel (Multichannel) mode, and the like.
It will be appreciated that the colors of an image are characterized by different components in different color modes.
Specifically, in the embodiment of the present invention, the parameter indicating the color of an image may be a component of the color of the image in a certain color mode. E.g. the first parameter of the first image, is a component of the color of the first image in a certain color mode.
For example, in HSB mode, the colors of an image are characterized by including an h (hues) component representing hue, an s (saturation) component representing saturation, and a b (brightness) component representing brightness. In the HSB mode, the higher the values of the S component and the B component in the first parameter, the higher the saturation and brightness of the first image. For example, the first parameter of the first image includes an H component, an S component, and a B component of the first image.
For example, in RGB mode, the color of an image is characterized by an R (RED) component, a G (GREEN) component, and a B (BLUE) component. For example, the first parameter of the first image includes an R component, a G component, and a B component of the first image.
For example, in CMYK mode, the color of the image is characterized by a C (CYAN) component, an M (MAGENTA) component, a Y (yellow) component, and a K (BLACK) component. For example, the first parameter of the first image includes a C component, an M component, a Y component, and a K component of the first image.
In the embodiment of the present invention, which color mode is used for recording the color of the image may be determined according to actual use requirements, and this is not specifically limited in the embodiment of the present invention.
And S203, the terminal equipment acquires a second image through a second camera component.
The first image and the second image are images collected under the same light environment.
Optionally, the second image is an image currently acquired and shot by the terminal device through the second camera assembly, or a current frame image acquired and previewed on a screen through the second camera assembly, or an image acquired in the background through the second camera assembly.
It should be noted that the order of executing the above S201 and S203 by the terminal device is not limited, for example, the terminal device may execute S201 first and then execute S203. However, the time when the terminal device executes S201 and the time when S203 are different from each other by a small amount, so as to ensure that the first image and the second image are images in the same light scene.
Specifically, the user actively uses the camera of the terminal device to take an image, and at this time, the main lens of the camera is triggered to take a picture. And if the camera is in a preview mode, the terminal equipment captures the image of the current frame acquired by the main lens.
It can be understood that, because there may be light sources with different color temperatures in the captured scene, there may be different color shifts in the captured picture by the main lens of the camera under the illumination of the light sources with different color temperatures, such as the content of the picture generally turns yellow under the illumination of the light source with a high color temperature, and the content of the picture generally turns blue under the illumination of the light source with a low color temperature. Therefore, in general, photos taken by ordinary users have a certain color cast phenomenon.
It can be understood that the second parameter of the color chart is the true color of the color chart, and the first parameter of the first image is the image of the color chart with color cast under the current light environment. Therefore, the degree of color cast of the image under the current light environment can be determined through the first parameter and the second parameter, and the calibration parameter can be obtained.
Specifically, since the gray calibration card and the scene shot by the main lens are in the light source environment with the same color temperature, the color shift of the gray calibration card and the color shift of the shot scene under the same light source are consistent. The calibration parameters calculated by the grey calibration card can correct the image shot by the main lens to a real picture.
And S204, the terminal equipment calculates a fourth parameter according to the calibration parameter and the third parameter of the second image.
Wherein the third parameter is used for indicating the color of the second image, and the fourth parameter is used for indicating the color of the target image.
It is understood that the second image with the third parameter is an image collected by the terminal device through the second camera assembly under the current light environment, and color cast may occur. The first image and the second image are images under the same light environment, so that the color cast degree of the first image and the color cast degree of the second image are the same, the calibration parameter can adjust the third parameter of the second image, and the adjusted fourth parameter is obtained.
And S205, the terminal equipment calibrates the second image into a target image according to the fourth parameter.
It is understood that the target image having the fourth parameter is an image of a true color.
Specifically, after the terminal device acquires the image with color shift from the main lens, the image captured by the main lens can be corrected by the calculated calibration parameters.
For example, if the second image is irradiated by a light source with a high color temperature, and the picture content is generally yellow, the target image with better picture content can be obtained by calibrating the yellow degree of the picture content through the calibration parameter. Therefore, the terminal equipment can restore the color of the collected image.
It should be noted that, through the above S205, the terminal device completes one calibration on the image captured by the main lens. When the user controls the terminal device to shoot the image, the image after color calibration is stored in the terminal device. And if the main lens is in the preview mode, continuing to calibrate the next frame of image according to the process.
Optionally, the terminal device may store the current calibration parameters. And subsequently, recalculating the calibration parameters once at intervals, and updating and storing the calibration parameters in the terminal equipment.
It can be understood that, in a scene in which a user controls the terminal device to capture an image, the terminal device may automatically capture a first image to automatically acquire calibration parameters in a current light environment; and calibrating the second image acquired in real time through the calibration parameter to obtain a calibrated target image. In this way, the user can manually control the terminal device to capture the second image, and does not need to manually control the terminal device to capture the first image, but can trigger the terminal device to capture the first image in the background. Therefore, the operation of the user in the process of calibrating the photo by the terminal equipment is simplified, and the man-machine interaction performance is improved.
It should be noted that, in the image processing method provided by the embodiment of the present invention, the first image may be acquired by the first camera component; calculating a calibration parameter according to a first parameter of the first image and a second parameter of the color card; acquiring a second image by using a second camera component; thereby, a fourth parameter is calculated according to the calibration parameter and the third parameter of the second image; calibrating the second image into a target image according to the fourth parameter; the first parameter is used for indicating the color of the first image, the second parameter is used for indicating the color of the color card, the first image and the second image are images collected under the same light environment, the third parameter is used for indicating the color of the second image, and the fourth parameter is used for indicating the color of the target image. Based on the scheme, the relative position of the color card and the lens in the first camera assembly is fixed, so that the terminal equipment can acquire the first image of the color card only by acquiring and shooting the image through the first camera assembly. Therefore, the method is beneficial to quickly and accurately acquiring the photo of the color card when the terminal equipment calibrates the photo. Furthermore, the method is beneficial to the terminal equipment to calibrate the photos taken by the user conveniently and quickly according to the calibration parameters, and the problem that the taken photos have color cast is solved.
In a possible implementation manner, in the image processing method provided by the embodiment of the present invention, the above S202 may be implemented by S202a and S202 b:
s202a, the terminal device calculates the ratio of the first parameter to the second parameter to obtain a first ratio.
S202b, the terminal device calculates a product of the first ratio and the first sensitivity parameter to obtain a calibration parameter.
The first sensitivity parameter is used for representing the light sensitivity of a lens in the first camera assembly.
Specifically, the terminal device calculates the calibration parameters using p (λ) ═ O1(λ)/R1 × c 1.
Where λ denotes a light environment in which the terminal device is located, p (λ) denotes a calibration parameter, O1(λ) denotes a first parameter, R1 denotes a second parameter, and c1 denotes a light sensitivity of a lens in the first camera assembly. O1(λ)/R1 is a first ratio, and c1 is a first sensitivity.
Specifically, O1(λ) represents the color of the first image of the color chart captured by the terminal device through the auxiliary lens in the light environment of λ. R1 represents the true color of the terminal device passing through the color chart, and p (λ) represents the calibration parameter under the light environment of λ.
Wherein, the value of lambda changes along with the change of the current light environment. Further, as λ changes, p (λ) and O1(λ) change.
The sensitivity of the same lens under different light environments is consistent. The first photoreception sensitivity c1 of the lens in the first camera assembly is a determined value.
Accordingly, the above S204 can be implemented by S204a and S204 b:
s204a, the terminal device calculates the ratio of the third parameter to the calibration parameter to obtain a second ratio.
And S204b, the terminal equipment calculates the product of the second ratio and the second sensitivity parameter to obtain a fourth parameter.
The second sensitivity parameter is used for representing the light sensitivity of a lens in the second camera assembly.
Specifically, the terminal device may calculate the fourth parameter using R2 ═ O2(λ)/p (λ) × c 2.
Where O2(λ) denotes a third parameter, R2 denotes a fourth parameter, and c2 denotes the light-sensing sensitivity of the lens in the second camera assembly. Specifically, O2(λ)/p (λ) is a second ratio, and c2 is a second photosensitivity.
It will be appreciated that typically the same brand or model of lens will have the same photosensitivity, e.g. c1 is the same as c2 described above.
Specifically, O2(λ) represents the color of the second image captured by the main lens in the light environment of λ by the terminal device. R1 represents the true color of the second image captured by the terminal device through the main lens.
It should be noted that, in the embodiment of the present invention, the terminal device may determine, in real time, the calibration parameter of the image acquired through the main lens of the second camera assembly in the current light environment, so that the image is calibrated through the calibration parameter, and an image with better picture quality is obtained.
