The camera's image processor (Image Signal Processor, ISP) typically has some automatic white balance (Automatic White Balance, AWB) capability. The automatic white balance processing parameter is calibrated under a standard lamp box or an illumination light source, and the principle is to simulate the color constancy of human eyes, namely, the automatic white balance processing parameter has automatic adaptation and adjustment capability to the change range of the color temperature of natural illumination or artificial common illumination light sources, so that the color finally seen by the human eyes is not changed.

In the practical application process, the camera is usually used in front on the television, and as the size of the screen of the liquid crystal television or the laser television is larger, the brightness level is higher, the emitted light can irradiate an object or a person to be reflected, and the reflected light can influence the camera. Especially when the influence caused by the reflected light exceeds the automatic white balance adjustable range of the camera, the output image is obviously color-shifted. When the ambient light is dark or the television screen is close to an object or a person, the color cast phenomenon is more obvious, and the user experience feel bad, so how to improve the color difference of the display image is a problem to be solved.

The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Example 1

Fig. 3 is a flowchart illustrating a shooting processing method according to an embodiment of the present application. The method is applied to a television, and the television comprises a display screen and a camera. The main execution body of the method can be a shooting processing device or a display device such as a television integrated with the shooting processing device. As shown in fig. 3, the method comprises the steps of:

S200, taking an original image acquired by a camera when a display screen is in an on state;

s300, acquiring a currently stored correction amount; the correction amount characterizes the difference between the display parameters of the image acquired by the camera when the display screen is in an on state and the display parameters of the image acquired by the camera when the display screen is in an off state; wherein the display parameters include white balance parameters and chromaticity values of typical colors;

s400, performing color cast correction on the original image according to the correction amount to obtain a corrected target image, and displaying the corrected target image on a display screen.

Specifically, the original image is an image which is affected by the reflected light of the screen and is color-shifted. In general, cameras themselves have some automatic white balance capability. When the color cast degree of the original image cannot realize normal color development through the automatic white balance capability of the camera, performing the color cast correction by executing the steps 200 to 400. The method comprises the steps of acquiring differences of display parameters of images acquired by a camera respectively in an on state and an off state of a display screen, and correcting color cast of an original image acquired by the camera in the on state of the display screen, so that the influence of light emitted by a television display screen on an object in a shooting scene reflected to a photosensitive element of the camera is removed, and color difference of the displayed image is improved.

In some embodiments, the correction amount described above may be acquired in real time. The step S200 specifically includes:

s201, acquiring a reference image when the display screen is in a closed state;

s202, acquiring a correction image acquired by a camera when a display screen is in an on state;

s203, comparing the corrected image with the reference image to obtain a correction amount, and storing the correction amount.

The reference image is acquired when the display screen does not emit light, and the imaging color of the reference image can reflect the current shooting scene more truly. In a possible embodiment, the reference image may be obtained by a camera of the television when the display screen is not emitting light. Specifically, a first shooting instruction of a user is received; and closing the display screen according to the first shooting instruction, controlling the camera to acquire a reference image, and storing the reference image. The first shooting instruction can be sent through a selection button of the remote controller; when the display screen of the television is a touch interactive screen, a first shooting instruction can be sent through clicking, sliding and other operations; the first shooting instruction can also be sent by detecting gesture, blink and other action behaviors of the user through a camera of the television.

In another possible embodiment, the reference image may also be acquired for photographing by a first device connected in communication with the television. Specifically, a reference image uploaded by a first device in communication connection with a television is received, wherein the reference image is acquired by the first device when a display screen is in a closed state. The first device has a photographing function, such as a smart phone having a photographing function, or the like.

Further, the corrected image is captured by a camera of the television. Specifically, a second shooting instruction of a user is received; and restarting the display screen according to the second shooting instruction, and controlling the camera to acquire a correction image. The correction image is compared with a previously stored reference image to obtain a correction amount. Further, the second shooting instruction can be sent through a selection button of the remote controller; when the display screen of the television is a touch interactive screen, a second shooting instruction can be sent through clicking, sliding and other operations; and the second shooting instruction can be sent by detecting gesture, blink and other action behaviors of the user by using a camera of the television. When the reference image and the correction image are acquired by the same camera, errors caused by different technological parameters of different image acquisition devices are not introduced, and the accuracy of the correction amount is improved.

In some embodiments, the order of acquiring the currently stored correction amounts may be to first perform step S201 to acquire the reference image, then perform step S202 to acquire the correction image, and then perform step S203 to obtain the correction amounts. In some embodiments, the order of acquiring the current correction amount may be to first perform step 202 to acquire the correction image, then perform step S201 to acquire the reference image, and then perform step 203 to acquire the correction amount. The order of acquiring the reference image and the original image is not limited in this application, and may be executed according to actual program settings.

Further, the shooting scene needs to be kept consistent when the original image and the reference image are acquired separately. For example, the photographing angle is the same, and the light of the photographing environment and the furnishing in the photographing scene need to be kept consistent in order to accurately acquire the correction amount. The display parameters include white balance parameters and chromaticity values of typical colors, and the method for obtaining the white balance parameters and the chromaticity values of the typical colors can refer to the related art. The typical color can be skin color, and when the television camera is applied to a shooting scene with a person, the skin color can be inaccurate in color development as a mixed color when the person is shot, and the color difference of a display image can be further improved by targeted adjustment according to the related technology.

The correction amount described above may be plural on the basis of the above embodiment. Specifically, step S200 further specifically includes:

s204, pushing a plurality of correction amounts to a user; wherein each correction amount is obtained and stored based on a reference image and a correction image in different shooting scenes;

s205, determining a correction amount according to a selection instruction of a user.

The correction amounts are used to adapt to different shooting scenes, for example, when the television shooting is used in the daytime and the television shooting is used at night, the light rays of the shooting environment are different, and thus the white balance parameters and the chromaticity values of typical colors are affected. For example, when the indoor light is used for shooting under the condition of cold light and when the indoor light is used for shooting under the condition of warm light, the color of the light is overlapped with the color of the object, and different colors are generated correspondingly, so that the chromaticity value of the typical color is influenced, and the white balance parameter is also influenced.

In the practical application process, the user has personalized preferences and habits, for example, the user fixes six to eight early morning video conferences by using television. When a user adjusts shooting parameters such as a proper shooting angle for the first time according to the current ambient light, and obtains a current correction amount, the correction amount can be stored. The correction amount can be directly called in the later early-morning video conference scene, and the correction amount does not need to be readjusted again, so that the time can be saved, and the user experience is improved.

Further, when an abrupt weather change condition such as a cloudy day is encountered, there is a possibility that the light of the photographing environment may change, so that the previously stored correction amount cannot meet the photographing requirement. At this time, the user can repeat the step of obtaining the correction amount to obtain a new correction amount so as to adapt to the current shooting scene, and the requirement of the user can be flexibly met. The correction amount can be directly called in the later cloudy day scene, so that the time is saved, and the user experience is improved.

Different correction amounts may be obtained and stored separately for different weather scenes, for different usage periods in a day. Further, in step S204, the order of the plurality of correction amounts pushed to the user may be sorted according to the last use time of the correction amount, and the probability that the last used correction amount is used again is high; the rule of the using time period of each correction amount can be counted, the correction amount close to the current moment is pushed, the setting of the correction amount is generally associated with the light of the shooting environment to a certain extent, the light of the shooting environment in different time periods in one day is different, and therefore the correction amount is associated with the using time period to a certain extent.

In some embodiments, before step S200, further includes:

s101, receiving a starting instruction of a self-correction function, starting a camera of a television according to the starting instruction, and displaying a preview image on a display screen of the television;

and S102, if an adjustment instruction is received, adjusting shooting parameters of the camera according to the adjustment instruction, and displaying images acquired by the camera after adjusting the shooting parameters on a display screen.

Specifically, the self-correction function can be started through the remote controller; when the display screen of the television is a touch interactive screen, a self-correction function can be started through touch screen operation; when an action gesture for starting the self-correction function is preset, the action behavior of the user is detected by the camera of the television to start the self-correction function, such as a gesture, blink, smile, or the like. After the self-correction function is started, the camera starts and shoots the current scene, and the preview image is displayed through the display screen. The original image of the current shooting scene to be shot can be determined through the preview.

Further, the user is prompted whether to adjust parameters such as shooting angle, shooting environment, shooting special effects and the like. Wherein, adjust shooting angle through the angle of adjustment camera. When the camera is detachably assembled in a clamping manner, the shooting angle needs to be manually adjusted by a user; when a rotating mechanism is arranged between the camera and the television, the camera can be rotated to a satisfactory shooting angle through the control of a remote controller or a touch screen.

Further, in general, televisions are used indoors, and the indoor ambient light is affected by the light emitted from the lamps and may also be affected by the light incident through the windows. For adjustment of the shooting environment, the user may select an appropriate light, such as warm light, cool light, etc., and the user may select whether to close the window covering. With the rise of smart home, smart televisions, smart light controls, smart curtains and the like are widely applied to every household. A user can realize cooperative control of each intelligent home through intelligent home management software such as mobile phone management software and the like so as to meet the living demands of the user.

In some embodiments, the adjustment instructions further include an adjustment to the captured special effects; step S400 specifically includes:

s401, performing color cast correction on an original image according to the correction amount to obtain a corrected target image;

s402, according to the shooting special effects, the target image is overlapped and shot special effects are generated, and the special effect image is displayed on a display screen.

For adjusting shooting special effects, a plurality of shooting special effects including overall special effects such as various filter special effects or beauty special effects and local special effects such as stickers and dressing are pushed to a user. And determining the shooting special effect according to the selection instruction of the user. Selecting and determining satisfactory shooting special effects through a selection button of a remote controller; when the display screen of the television is a touch interactive screen, satisfactory shooting special effects can be selected and determined through clicking, sliding and other operations; and the camera of the television can be used for detecting action behaviors such as gestures, blinks and the like of the user to select and determine satisfactory shooting special effects.

Specifically, when special effect processing is preset by a user, color cast processing is performed on an original image according to a correction amount, and then special effect processing is performed on the image subjected to color cast correction. The shooting processing method provided by the embodiment of the application can be used for superposing and processing for a plurality of times, and further meets the personalized requirements of users on the basis of improving the color difference of the display image.

Further, the user can select at least one of the shooting angle, the shooting environment and the special effect to adjust, and can not adjust either, so that personalized requirements of the user can be met.

In some embodiments, fig. 4 is a schematic flow chart of acquiring a correction amount according to an embodiment of the present application, which illustrates a shooting processing method in a scenario of acquiring the correction amount in real time. As shown in fig. 4, the operation is as follows:

firstly, a self-correction function is started, a correction mode is entered, a camera is started, and a preview image is displayed on a display screen. The self-correcting function can be started automatically when the television is started, or can be started manually by a user. The starting instruction can be sent through a remote controller or through a touch interactive display screen.

Further, the user is prompted to adjust to a satisfactory shooting angle, shooting environment and special effects. Wherein, the adjustment result can be seen in real time through the preview. For example, after the special effects are selected, the actual presentation effect of the special effects can be observed through the preview, so that the user can be helped to select the proper special effects.

Further, after the setting is completed, whether to take the reference image is prompted, and if not, the shooting parameters such as the shooting angle, the shooting environment, the special effect and the like can be continuously adjusted. If the reference image is shot, the backlight of the liquid crystal television is controlled to be turned off or the laser light source of the laser television is controlled to be turned off, and the shooting of the reference image is executed. The reference image removes the influence of light emitted by the television screen on objects in the shooting scene and reflected to the photosensitive elements of the camera.

Further, the reference image is stored, backlight of the liquid crystal television is controlled to be turned on or a laser light source of the laser television is controlled to be turned on again, so that a television display screen normally emits light, and at the moment, a correction image displayed by a television screen preview image is displayed.

Further, the corrected image is photographed, compared with the previously stored reference image, and correction amounts such as the white balance parameter adjustment value and the chromaticity adjustment value of the typical color are extracted and calculated, and stored.

In some embodiments, fig. 5 is a flowchart illustrating a process of applying a correction amount according to an embodiment of the present application. The correction amounts obtained in fig. 4 are stored in the memory, and a plurality of sets of correction amounts may be stored. In the application process, a real-time original image is shot by a camera and is transmitted to a decoder; the decoder decodes the original image and transmits the decoded image to the arithmetic unit; the arithmetic unit performs color shift correction processing on the decoded image according to the correction amount (white balance parameter adjustment value, chromaticity adjustment value of typical color, etc.), and transmits the processed data to the display screen, displaying the normally developed image.

In summary, the shooting processing method provided by the embodiment of the application is applied to a television, and the television comprises a display screen and a camera. The method comprises the following steps: acquiring an original image acquired by a camera when a display screen is in an on state; acquiring a currently stored correction amount; the correction amount characterizes the difference between the display parameters of the image acquired by the camera when the display screen is in an on state and the display parameters of the image acquired by the camera when the display screen is in an off state; and correcting the color cast of the original image according to the correction amount to obtain a corrected target image and displaying the corrected target image on a display screen. In the embodiment of the application, a reference image when the display screen does not emit light is taken as a reference, and is compared with a correction image when the display screen emits light normally to determine a correction amount; and the correction amount is used for carrying out color cast processing on the original image, so that the color difference of the display image is improved. In addition, the user can store the correction amount according to own habits and preferences, and can directly call the previously stored correction amount for the same shooting scene without repeated calculation, thereby being beneficial to improving the user experience; the user can flexibly update the correction amount according to the change of the environment so as to adapt to different shooting scenes.
