Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, a flowchart of a photographing method according to an embodiment of the present invention is shown, and is applied to a mobile terminal including a first screen and a second screen.

The shooting method in the embodiment is applied to a mobile terminal with a double-sided screen, the mobile terminal with the double-sided screen comprises a first screen and a second screen, and under a general condition, display surfaces of the first screen and the second screen are arranged in a back-to-back mode. Based on the above characteristics of the mobile terminal with the double-sided screen, the shooting method comprises the following steps:

step S1: and displaying the preview image through the first screen, and acquiring the main brightness information, the background brightness information and the white balance information of the preview image.

In the step, the user can open the camera software and control the rear camera to acquire images.

Generally, a mobile terminal of a dual screen includes a main screen for implementing a function and a sub-screen for implementing a function. Preferably, the first screen is a main screen and the second screen is a sub-screen. And controlling the first screen to enter a shooting preview interface so as to realize a shooting function. The method comprises the steps of shooting a preview interface to display a preview image, identifying a main body of the preview image and a background except the main body, for example, identifying a human face area as the main body by using an image identification technology, identifying an environment except the main body as the background, and further acquiring corresponding main body brightness information and background brightness information and white balance information of the preview image.

Step S2: determining the light supplementing brightness according to the main body brightness information and the background brightness information; and determining the supplementary lighting color temperature according to the white balance information.

And determining the required fill-in luminance according to the acquired main body luminance information and the acquired background luminance information so that the fill-in luminance acts on the main body and the main body luminance information is matched with the background luminance information.

And determining the color temperature of the light supplement according to the acquired white balance information, so that the color temperature after light supplement is matched with the original white balance information.

Step S3: and controlling the second screen to emit bright light according to the fill light brightness and the fill light color temperature.

In the step, the second screen is controlled to be lightened, and the second screen enters a light supplement interface, so that the second screen emits light to replace a traditional flash lamp to play a light supplement role in shooting.

In the prior art, a flash lamp is used for light supplement, and the flash lamp illuminates the face of a person to achieve the light supplement effect on a shooting main body. However, because the flash lamp usually has only one power output, the luminance of the light supplement is not controllable, so that the luminance difference between the shooting main body and the background region cannot be considered when the flash lamp supplements light, the output shooting main body is shot, the environment atmosphere does not exist, and particularly when the background is a night scene, the night scene cannot be highlighted. Based on the above process, it can be seen that the shooting method in the embodiment adopts screen light supplement, which can effectively overcome the problems in the prior art.

In addition, since a subject such as a general person is dark when shooting in a dark environment, a luminance difference between the subject and the background is reduced as a starting point of light supplement. The second screen emits a bright light to act on the photographic subject for changing the subject luminance information to adapt the subject luminance information to the background luminance information.

On the basis of the embodiment shown in fig. 1, fig. 2 shows a flowchart of a photographing method according to another embodiment of the present invention, and step S3 includes:

step S31: and controlling the second screen to emit bright light according to the fill-in light brightness.

Preferably, after the user opens the camera software, the first screen can be synchronously controlled to display the preview image, and the second screen can be controlled to emit bright light.

In the step, the fill-in luminance is calculated according to the main body luminance information and the background, the fill-in luminance obtained here is an approximate numerical value, and meanwhile, the obtained fill-in luminance is only based on theoretical data and does not act in the actual state, so that after the second screen is controlled to emit the bright light according to the obtained fill-in luminance, the effect of the second screen applied in the actual state needs to be detected, and then the next step is carried out.

Step S32: and controlling the bright light to continuously flicker, and controlling the display brightness of the bright light to gradually change in the flicker.

And on the basis of the initial supplementary lighting brightness, controlling the second screen to emit the bright light, then controlling the bright light to continuously flicker, and controlling the display brightness of the bright light to gradually change in the flicker so as to realize fine adjustment of the display brightness of the bright light in the flicker.

The display brightness of the bright light is finely adjusted by using a flickering mode, so that the bright light can be prevented from directly irradiating human eyes and the like, the phenomenon of red eyes and the like in shooting is avoided, and the quality of the shot image is further optimized.

Step S33: and acquiring the main body brightness information of the preview image after the light supplement.

The bright light of the second screen directly acts on the main body, so that the change of the main body brightness information can be reflected in the preview image, the main body brightness information after light supplement is obtained in real time, and the adaptation degree between the main body brightness information after light supplement and the background brightness information is synchronously detected.

Step S34: and if the acquired main body brightness information after the supplementary lighting is matched with the background brightness information, controlling the lighting to stop flickering and changing.

And if the acquired main body brightness information after light supplement is matched with the background brightness information, determining the final light supplement brightness, and controlling the bright light to stop flickering and changing.

Step S35: and determining the color temperature of the bright light according to the supplementary light color temperature.

In this step, a white balance analysis method is applied to determine the color temperature of the second screen emitting bright light. Specifically, first, white balance information in the preview image is obtained, where the white balance information is white balance information before light supplement, and for example, the white balance information is several K. And then analyzing the acquired white balance information to endow the same white balance information to the light supplementing light source according to the white balance information, namely controlling the color temperature of the bright light emitted by the second screen to be the same as that of the light before supplementing, and avoiding the phenomena of unnatural light supplementing and the like from occurring to influence the quality of the shot image.

The second screen can be controlled to emit bright light with infinite colors for light supplement, the effect that light supplement color temperature and white balance information of preview images are adaptive is achieved, the environment atmosphere of the output images is good, front and back scenery colors are harmonious, light supplement effects are naturally fused, and the appearance of human eyes is met.

In this embodiment, a specific light supplement scheme is provided, and by fine tuning of light supplement luminance and combining an effect applied in practice, the optimal light supplement luminance is finally determined, and the light supplement effect is further optimized.

On the basis of the embodiment shown in fig. 2, fig. 3 shows a flowchart of a photographing method according to another embodiment of the present invention, and step S32 includes:

step S321: the bright light is controlled to continuously flash at a rate greater than the first frequency.

In the step, the bright light emitted by the second screen is controlled to flicker in high frequency, wherein the flicker frequency needs to be greater than a certain value so as to meet the requirement of high frequency. Therefore, the optimal light supplement brightness can be determined quickly, too much time is avoided being spent in the process of adjusting the light supplement brightness, and the shooting experience of a user is improved.

In fig. 3, which also shows a flowchart of a photographing method according to another embodiment of the present invention, step S32 includes:

step S322: controlling the display brightness of the bright light to gradually change from low to high in the flicker; alternatively, the display brightness of the control bright light is gradually changed from high to low in the blinking.

In this step, the display brightness of the bright light may be changed from low to high or from high to low.

For example, based on the current display brightness gradually increasing, if the detected result indicates that the adaptation degree of the main brightness information and the background brightness information is higher and higher, the display brightness of the second screen brightness is continuously increased; if the detected result indicates that the adaptation degree of the main brightness information and the background brightness information is lower and lower, the change mode can be adjusted to control the display brightness to be gradually reduced.

By the scheme of gradually changing the display brightness according to a rule in the embodiment, the optimal fill-in light brightness can be determined in the gradual change.

It should be noted that if the brightness emitted by the second screen continuously increases the display brightness in the High-frequency flicker, but the adaptation of the main brightness information after light supplement to the background brightness information is not detected until the maximum display brightness of the second screen cannot achieve the effect of the adaptation of the main brightness information to the background brightness information, a High-Dynamic Range (HDR) algorithm may be used to perform High light ratio shooting to achieve sufficient light supplement.

On the basis of the embodiment shown in fig. 1, fig. 4 shows a flowchart of a shooting method according to another embodiment of the present invention, and after step S3, the method further includes:

step S4: and receiving the adjustment operation of the bright light on the first screen by the user.

The supplementary lighting adjustment area can be displayed in a shooting preview interface of the first screen. On the one hand, along with the gradual change of the bright light that the second screen sent, the user can see the light filling change in real time in the light filling adjustment region. On the other hand, the user may also manually adjust the change in the bright light. Thus, in this step, the adjustment operation of the bright light by the user on the first screen is received.

For example, the second screen emits the bright light and then acts on the preview image, and the user can see the change in the preview image in real time, so that the bright light can be adjusted according to the actual supplementary lighting effect.

Step S5: the bright light is adjusted in response to the adjustment operation.

Preferably, the light supplement adjusting area comprises a brightness adjusting area, the brightness adjusting area is arranged as a horizontal bar, an action point is arranged on the horizontal bar, and a user drags the action point on the horizontal bar to control the display brightness of the bright light emitted by the second screen to gradually change.
