At present, the camera has become the standard configuration of most mobile terminals. With the continuous improvement of camera performance, the camera function in mobile terminals has become more and more powerful, which has brought convenience to users who like to take pictures.

Many mobile terminal users like to use the front camera on the mobile terminal to take photos, but the front cameras of existing mobile terminals are not equipped with fill light. When taking selfies at night or in a poorly lit environment, it will be caused by insufficient exposure. It is difficult to obtain the ideal self-timer effect, so the screen fill light function was developed. The screen fill light is based on the screen itself emitting white light to fill the screen self-timer in the dark. The white light hits the human face will reflect the skin color and facial details, which are captured by the camera to respond to night scenes or dark light selfies.

【detailed description】

In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Referring to FIG. 1, a screen fill light correction method according to the present invention includes:

S101. Control a screen of a mobile terminal to emit white light for supplementary light, and a front camera of the mobile terminal and the screen face a white reference object;

The mobile terminal may be a mobile terminal device such as a mobile phone or a tablet computer. The mobile terminal has a front camera and a screen. In this embodiment, the mobile terminal is described by using a mobile phone as an example. When it is necessary to correct the screen light of the mobile phone, The front camera and screen of the mobile phone need to be directed to a white reference object, so that the object captured by the front camera is the white reference object, and the light emitted by the screen can be reflected by the white reference object. The white reference object can be a white wall or other white object.

It should be noted that, in order to improve the user experience, the user can be guided to correct the screen fill light. Before step S101, when it is detected that the screen fill light event is triggered, guide information is issued, and the guide information is used for guidance. The user turns on the front camera of the mobile terminal, and makes the subject of the front camera the white reference object. Specifically, a screen fill light option can be set in the operation interface of the mobile phone. When the user clicks the screen fill light option on the screen, it is detected that the screen fill light event is triggered. At this time, an interactive operation can also be issued for the user Select whether to perform screen fill light correction. For the case of screen film, the user can choose to perform screen fill light correction, and then issue the above-mentioned guidance information. The guidance information can prompt the user in the form of a prompt box or a voice; In the case where the screen is not filmed, the user can also choose not to perform correction of the screen fill light to improve the interactive experience.

S102. Receive reflected light reflected by the white reference object collected by the front camera;

In the case of the screen film, the white supplementary light emitted by the mobile phone screen will first pass through the film, and then irradiate the white reference object, and then reflect the white reference object to the front camera, and collect the reflected light through the front camera.

S103: Perform chromatographic analysis on the reflected light to determine a color of the reflected light;

Among them, the sapphire film on the screen of the mobile phone is taken as an example to explain. Since the sapphire film is light blue, the white light emitted by the screen will also become light blue after passing through the film, because the film absorbs In addition to blue light, only light blue light passes through the film; the light blue light hits the white reference object and is reflected back to form light blue reflection light, light blue reflection The light is then captured by the front camera. Therefore, by performing spectral color analysis on the reflected light, it can be determined that the color of the reflected light is light blue, that is, the white supplementary light emitted by the previous screen is turned into a light blue light after passing the film. Among them, the spectral color analysis can be implemented by presetting an image processing program in a mobile phone and analyzing the RGB values of the collected light.

S104. Attenuate the color of the reflected light among the white light emitted by the screen.

Among them, because the color of the reflected light is light blue light, that is, after the white light emitted from the screen passes through the film, the light blue light remains more than the light of other colors. Therefore, the light emitted by the screen is weakened. The light blue light of the white light to offset the effect of the film on the white fill light emitted by the screen. Specifically, white light can be regarded as a combination of three primary colors of red (R), green (G), and blue (B). When the RGB values of the three primary colors are R = G = B = 255, the light emitted by the screen is For white light, you can adjust the R value of the red primary color light, the G value of the green primary color light, and the B value of the blue primary color light to weaken the light blue in the white light emitted by the screen and achieve fill light correction.

Please refer to FIG. 2, a screen fill light correction method according to a second embodiment of the present invention. The method includes:

S201. Control the screen of the mobile terminal to emit white light for supplementary light, and the front camera of the mobile terminal and the screen face a white reference object;

S202: Receive reflected light reflected by the white reference object collected by the front camera;

S203: Perform chromatographic analysis on the reflected light to determine a color of the reflected light, and calculate a weight ratio of the color of the reflected light to white light;

In this embodiment, the sapphire film on the screen of the mobile terminal is also taken as an example for explanation. Since the sapphire film is light blue, the white light emitted by the screen will also become light blue after passing through the film. This is because the film absorbs light of other colors except blue light, so only light blue light passes through the film; the light blue light hits the white reference object and is reflected back to form a light blue reflection. The light, light blue reflected light is then captured by the front camera. Therefore, by performing spectral color analysis on the reflected light, it can be determined that the color of the reflected light is light blue, that is, the white supplementary light emitted by the previous screen is turned into a light blue white light after the film is applied. At the same time, the spectral color analysis can Calculate the weight ratio of the reflected light blue light in the overall spectrum (that is, white light), for example, calculate the weight ratio of the reflected light blue light in white light, which is 15%, that is, light blue in white The proportion of light is 15%.

S204, attenuate the color of the reflected light in the white light emitted by the screen according to the weight ratio;

Among them, since the weight ratio of the reflected light blue light in the white light is calculated in step S203, 15% of the light blue light weight in the white light is weakened when the supplemental light correction is performed.

S205. Determine whether the reflected light after attenuation is white light;

S206. If not, repeat steps S203-S204 until the reflected light is white light.

The method provided in this embodiment is based on the first embodiment. In addition to the effects of the first embodiment, it can accurately calculate the supplementary correction to ensure that the light emitted by the final screen after the film is white, further improving the selfie experience. .

It should be noted that this embodiment focuses on the differences from the previous embodiment. The same or similar parts between the embodiments are not described repeatedly and can be referred to each other.

Referring to FIG. 3, a screen fill light correction method according to a third embodiment of the present invention, the method includes:

S301. Control the screen of the mobile terminal to emit white light for supplementary light, and the front camera of the mobile terminal and the screen face a white reference object;

S302. Divide the preview image or captured image of the front camera into several first regions, and simultaneously divide the screen into several second regions according to the ratio of the preview image or captured image to the screen. The first area corresponds to the second area in a one-to-one correspondence;

For example, the preview image or captured image of the front camera is divided into n * m first areas, and the shape of the first area is, for example, rectangular. Similarly, the screen of the mobile terminal (specifically, the display area) is corresponding to the corresponding proportion. Divided into n * m second regions, the shape of the second region is the same as that of the first region, and the first region corresponds to the second region one by one, that is, the first region is the enlarged second region.

S303. Perform brightness analysis on the preview image or the captured image of the front camera to determine a first region in the preview image or the captured image that is weaker in brightness;

For the case where a film is attached to the screen of the mobile terminal, the white light emitted by the screen passes through the film, and then is reflected by the white reference object and enters the front camera. After the front camera is turned on, it can be performed by previewing or capturing images. Brightness analysis. The thicker the film, the more difficult it is for the fill light from the screen to penetrate, resulting in a lower brightness of the fill light. Conversely, the thinner the film, the easier it is for the fill light from the screen to penetrate, resulting in a brighter fill light. For the reason of the filming process, the thickness of the filming may be different in different regions. Therefore, by performing a brightness analysis on the preview image or the captured image of the front camera, a first region with weaker brightness in the preview image or the captured image can be determined.

Specifically, when determining the first area having a relatively low brightness in the preview image or the captured image, a corresponding brightness value may also be determined, for example, the first area in the second row and the third column is relative to other first period areas. The brightness is weak. The brightness value of the first region of the second row and the third column is specifically 0.5L, while the brightness values of the other first period regions are all L.

S304. Enhance the brightness of the white light emitted by the corresponding second region in the screen according to the first region in the preview image or the captured image that is relatively weak.

Specifically, the brightness of the second region in the second row and the third column of the screen of the mobile terminal needs to be enhanced. Specifically, according to the brightness value (0.5L) of the first region in the second row and the third column and other first periods The difference between the brightness values (L) of the areas enhances the brightness of the second area in the second row and the third column, and enhances the corresponding second area in the screen according to the preview image or the first area in the captured image that is relatively weak. The brightness of the white light emitted from the area is equal to the brightness value of each first area in the preview image or captured image.

According to the screen fill light correction method provided in this embodiment, the thickness of the film can be compensated and corrected. For thicker areas, the brightness of the fill light is actively increased, so that the fill light can pass through the thick and uneven film. The overall brightness of the rear light is uniform, so as to better fill the screen.

Please refer to FIG. 4, a screen fill light correction method according to a fourth embodiment of the present invention. The method includes:

S401. Control the screen of the mobile terminal to emit white light for supplementary light, and the front camera of the mobile terminal and the screen face a white reference object;

S402. Divide the preview image or captured image of the front camera into several first regions, and simultaneously divide the screen into several second regions according to the ratio of the preview image or captured image to the screen. The first area corresponds to the second area in a one-to-one correspondence;

S403: Perform a chromatographic analysis on the preview image or the captured image of the front camera to determine a first area in the preview image or the captured image that has more color retention;

The film may also have a problem of color unevenness. Therefore, in this embodiment, the first area in the preview image or captured image that has more color retention is first determined. Specifically, the preview image or captured image may be determined in the first area. The first region with more color retention and the corresponding color weight ratio.

S404: Attenuate the colors corresponding to the regions with more color retention among the white light emitted from the corresponding second region on the screen according to the first region with more color retention in the preview image or the captured image.

Wherein, this step may specifically be to weaken the white light emitted from the corresponding second area on the screen according to the first color area in which the preview image or the captured image retains more colors and according to the corresponding color weight ratio. The color retains the colors corresponding to the more areas until the color of the preview image or captured image is white.

According to the screen fill light correction method provided in this embodiment, the color difference of the film can be compensated and corrected. For areas with more color retention (that is, areas with the largest color difference), the corresponding colors in the fill light in the area are actively weakened. In the end, the supplementary light is still white after passing through the chromatic aberration film, so as to better perform screen supplementation.

It should be noted that, for a film that has both uneven thickness and color difference, the technical content of the third embodiment and the technical content of the fourth embodiment can be combined, and the thickness and color difference can be adjusted at the same time to ensure that the light of the fill light is transmitted through. The brightness after the film is uniform, and the color is still white, so as to better fill the light.
