The invention provides a method of filling light photographing.

Referring to FIG. 2, FIG. 2 is a schematic flow chart of a first embodiment of a photo-filling photographing method according to the present invention.

In this embodiment, the fill light photographing method is applied to a mobile terminal, and the mobile terminal includes a front camera and a front flash, and the fill light photographing method includes the following steps:

Step S10, when receiving the pre-photographing instruction, controlling the screen brightness of the mobile terminal to fill light, and acquiring the first image through the front camera when the screen is filled;

Currently, most smartphones on the market are equipped with front-facing cameras, and self-portraits or other things with the front camera have become mainstream. Taking pictures with the front camera, when the surrounding light is dim, the photos taken will be too dark due to insufficient light, which affects the sharpness of the image. There are two kinds of traditional front camera fill light photography methods, one is the flash fill light photo, the other is the screen fill light photo. However, the two have their own defects, the uniformity of the flash fill light is poor, although the face and part of the background can be illuminated, but it is easy to cause the background is clear but the face is too exposed, or the face is too dark and the background is too dark Screen fill light can evenly illuminate the face, but the fill light range is limited to the face of the face, other backgrounds are often difficult to illuminate. Therefore, these photographing methods have certain defects.

Based on the above problem, the present embodiment proposes a fill light photographing method to solve the technical problem that the front camera of the mobile terminal lacks the brightness of the photograph.

Specifically, the fill light photographing method in this embodiment is applied to a mobile terminal, and the mobile terminal in the following description will take a mobile phone as an example for description. The camera is provided with a camera on the same side of the screen, and the camera on the same side of the screen is called a front camera in order to distinguish it from the camera on the back of the mobile phone. It should be noted that the front camera in this embodiment may be a fixed camera fixed on the screen side of the mobile phone, or may be a rotatable camera whose current position is on the screen side of the mobile phone. Further, on the same side of the screen of the mobile phone, in addition to the front camera, a front flash is also provided for filling light during front camera shooting.

In this embodiment, when the user needs to use the front camera of the mobile phone to perform self-photographing, the user can open the camera interface in the mobile phone and click the front camera option to trigger the front camera command; of course, the user can also pass the text input mode. Input the command text or command code corresponding to the front camera command to trigger the pre-shooting command; of course, the front camera command can be triggered by voice input. When the mobile phone receives the pre-shooting command, it will activate the camera function of the front camera and enter the front shooting mode. When entering the front shooting mode, the mobile phone first controls the brightness of the screen to increase the display brightness of the screen, thereby filling the current shooting. At this time, the light emitted from the screen of the mobile phone can be regarded as a surface light source; in the state where the surface light source is illuminated, the face in front of the front camera of the mobile phone will be evenly illuminated, achieving the effect of soft light; At the same time, since the brightness of the screen is lowered relative to the flash, it is not irritating to the human eye, and the user can take a picture with a more natural expression on the screen fill light. While the screen is being filled, the mobile phone screen will also display the image currently captured by the front camera. The user can adjust his movements, facial expressions or the shooting angle of the mobile phone according to the content displayed on the screen; the user is determined to shoot. When the photo button is pressed on the mobile phone (the camera button can be a virtual button in the virtual keyboard of the mobile phone screen, or a physical button such as a volume button or a Home button); the mobile phone is supplemented by the screen according to the user's operation. The first image is acquired by shooting through the front camera. Of course, the user can also use the voice to control the mobile phone to take pictures, or set a delayed photo.

Step S20, the front flash is turned on to fill light, and the second image is acquired by the front camera when the flash is filled;

In this embodiment, when the mobile phone acquires the first image in the screen fill state, the photographing is not immediately stopped. At this time, the mobile phone will turn on the front flash and fill the light through the front flash; at this time, the flash fill light is similar to the point light source, and its center brightness is high, which can illuminate the face and background; the phone will fill the light in the flash In the state of the camera, the second image is acquired by the front camera. That is to say, step S10 and step S20 are performed in a state in which the screen fill light and the flash fill light are respectively performed in a short time; first, the first image is captured by the screen fill light, and then the flash is used to fill the light. The method completes the shooting of the second image to obtain the first image and the second image; of course, in the actual process, the second image may be captured by the flash fill light, and then the screen fill light is completed. The photographing of an image and the order of the filling modes do not constitute a limitation of the technical solution of the embodiment.

Step S30, synthesizing the first image and the second image to obtain a target image.

In this embodiment, the first image is captured in the screen fill state, and the screen fill light can be regarded as the surface light source; in the state where the surface light source is illuminated, the face in front of the front camera of the mobile phone will It will be evenly illuminated, achieving a soft light effect for clear imaging, and because the brightness of the screen is reduced relative to the flash, it will not irritate the human eye, and the user can fill the screen with a more natural expression. Taking pictures, but because the brightness of the screen is low, the range of fill light is limited to the face and the surrounding area. Other backgrounds are usually difficult to illuminate, so the face in the first image can be clearly imaged except near the screen of the mobile phone. In addition, the brightness of other backgrounds is darker. On the other hand, the second image is taken in the flash fill state, and at this time, the flash fill light is similar to the point light source, and its center brightness is high, which can illuminate the face and the background, but the flash brightness is high. It is also easy to cause overexposure, resulting in a clear background in the second image but the image of the face and surrounding is not clear.

According to the above problem, in the embodiment, the first image and the second image may be combined, and the clear portions of the first image and the second image are respectively taken, thereby obtaining an overall clear target image. Specifically, the mobile phone acquires the face image in the first image, acquires the background image in the second image, and superimposes the face image and the background image to obtain the target image. As with the above analysis, the face image in the first image is clear, and the background image in the second image is also clear, so the superimposed composite target image is also clear overall.

Further, the obtaining of the face image in the first image may be implemented by: when obtaining the first image and the second image, the mobile phone first performs face detection on the first image, and identifies the first image. Face area, in which face detection generally has the following methods:

1 reference template method: first design one or several standard face templates, then calculate the degree of matching between the sample collected by the test and the standard template, and judge whether there is a human face through the threshold;

2 face rule method: Since the face has a certain structural distribution feature, the method of the face rule is to extract these features to generate corresponding rules to determine whether the test sample contains a human face;

3 sample learning method: This method adopts the method of artificial neural network in pattern recognition, that is, the classifier is generated by learning the face image sample set and the non-image sample set;

4 skin color model method: This method is based on the law that the skin color distribution is relatively concentrated in the color space;

5 feature sub-face method: This method treats all face image sets as one face image subspace and determines whether there is a face image based on the distance between the detected sample and its projection in the subspace.

The specific face recognition process may adopt the above-mentioned face detection technology, and of course, other existing face detection technologies may be used, which are not specifically limited in this embodiment.

Upon identifying the face region in the first image, the handset will perform edge detection and cutting on the face region to distinguish the face region in the first image from other regions in the first image. When the distinction is completed, the mobile phone will transparently process other areas than the face area in the first image. When the transparency processing is completed, all the areas except the face area in the original first image are transparent, thereby obtaining a face image.

Still further, for the background image acquisition of the second image, a method similar to the face image acquisition may be employed. Specifically, the second image is subjected to face detection to identify a face region in the second image; when the face region in the second image is recognized, the region other than the face region is in the second image a background area; at this time, edge detection and cutting are also performed on the face area to distinguish the face area of the second image from the background area; when the distinction is completed, the face area in the second image is transparently processed; When the transparency processing is completed, the face area in the original second image is transparent, thereby obtaining a background image without the face area.

When the face image and the background image are obtained, the face image and the background image are superimposed, that is, the target image is obtained.

In this embodiment, for the second image obtained in the flash fill state, the background other than the face is mainly photographed to obtain the background image, so the requirement for the face portion is lower, and the brightness of the flash is higher. High, when the flash is flashing, the sudden bright light has a certain stimulation to the human eye. Therefore, when taking the second image, the user can close the eye to take photos, avoiding the flashing of the flash to the human eye. Of course, in order to prompt the user, the mobile phone can issue a voice prompt during the whole process of shooting to prompt the current fill mode. For example, when controlling the brightness of the screen to fill the light, the mobile phone can issue a “currently fill light” voice prompt; in the flash fill mode, the mobile phone can issue a “current flash fill light” voice prompt, the user is hearing When the voice prompts, the eyes can be closed to avoid the stimulation of the flash by the flash.

In this embodiment, when the pre-photographing instruction is received, the screen brightness of the mobile terminal is controlled to fill light, and the first image is acquired by the front camera when the screen is filled; the front flash is turned on. Filling light, and acquiring a second image through the front camera when the flash is filled; synthesizing the first image and the second image to obtain a target image. In the above manner, the embodiment performs shooting by means of screen fill light and flash fill light, and synthesizes the photos obtained by the two fill modes, extracts and clears the clear parts in each photo, thereby making Both the portrait and the surrounding environment can be clearly presented on the photo, which improves the brightness and clarity of the photo; the operation method is simple, and the camera performance and the photo quality are improved, and the cost is not increased.

Referring to FIG. 3, FIG. 3 is a diagram of controlling the screen brightness of the mobile terminal to fill light when receiving the pre-photographing instruction, and acquiring the first image through the front camera when the screen is filled. Refine the process diagram.

Based on the embodiment shown in FIG. 2 above, step S10 includes:

Step S11, when receiving the pre-photographing instruction, acquiring the current ambient light intensity, and controlling the screen brightness of the mobile terminal according to the ambient light intensity to fill light;

In step S12, the first image is acquired by the front camera when the screen is filled.

In this embodiment, when the light is supplemented by the brightness of the screen, the mobile phone controls the brightness of the screen according to the current ambient light intensity. Specifically, when receiving the pre-shooting instruction triggered by the user, the mobile phone will activate the camera function of the front camera to enter the front shooting mode; at the same time, the mobile phone will obtain the current ambient light intensity through the photosensitive element, wherein the photosensitive element It can be set separately in the mobile phone, or it can be integrated inside the front camera; when the ambient light intensity is obtained, the ambient light intensity is compared with the preset standard light intensity to determine whether the ambient light intensity is less than the preset standard. Light intensity, wherein the preset standard light intensity is a preset parameter value, which can understand the light intensity value that the front camera can clearly image, and can have different preset standard light intensity for different front cameras; If the light intensity is less than the preset standard light intensity, it indicates that the ambient light intensity is relatively high. At this time, the difference between the preset standard light intensity and the ambient light intensity is calculated, and then the preset screen brightness control is controlled according to the difference. Find the corresponding screen brightness parameter on the parameter table, and increase the screen according to the brightness parameter. The brightness is complemented, wherein the preset screen brightness control parameter table can be understood as a relationship between the light intensity difference and the screen brightness. The table can be used to determine whether the screen brightness should be adjusted in the case of a certain light intensity difference. The screen fills the light best; if the ambient light intensity is greater than or equal to the preset standard light intensity, then the phone will maintain the current screen brightness.

When the adjustment of the screen brightness is completed, the image can be taken while the screen is being filled, and the first image is acquired.

Step S40, when receiving the image adjustment instruction, adjusting an image parameter of the target image according to the image adjustment instruction, wherein the image parameter includes at least one or more of contrast, saturation, and exposure.

In this embodiment, after the first image and the second image are combined to obtain the target image, the mobile phone will display the target image on the screen to facilitate the user to view; if the user thinks that the target image does not meet the requirement, The target image can be manually adjusted twice. Specifically, when the mobile phone displays the target image, an image parameter adjustment option is also displayed, and the image parameters that can be adjusted include image contrast, saturation, exposure, brightness, size, and the like. Of course, the mobile phone can also call the original first image and the second image, and display the target image, the first image and the second image respectively in the same interface for the user to compare and view; the user can also manually use the first image in the first image. And the overlapping area is selected in the second image, and then the new target image is re-synthesized. Of course, the phone can also support other common image editing operations, such as rotation, cutting, graffiti, and so on.
