Exemplarily, as shown in fig. 3, an application scenario of the light supplement method according to the embodiment of the present invention is shown, in fig. 3, a is a terminal device for taking a picture, a1 is a first screen of the terminal device, and a2 is a second screen of the terminal device; b is the object photographed, D is the desk lamp light source. Due to the fact that the terminal device shields light, the B object has two regions with alternate light and shade, wherein the brightness of the B1 region is low due to the fact that the light is shielded, and the brightness of the B2 region is high due to the fact that the light is not shielded.

In the embodiment of the invention, in order to improve the brightness of the B1 area of the object B in fig. 3, the terminal device lights the second screen, and light of the second screen is used for supplementing light to the B1 area. Specifically, the terminal device may determine a dark region in the first preview image displayed on the first screen (i.e., a preview image of a captured B object), then determine a first display region C1 in the second screen corresponding to the dark region according to the position of the dark region in the first preview image on the screen of the terminal device, and finally fill the B1 region with light by lighting the C1 region, where the C2 region is a non-light region in fig. 3.

The embodiment of the invention provides a light supplementing method.A terminal device comprises a first screen and a second screen, and when a first preview image is displayed on the first screen, a dark area in the first preview image is determined, wherein the first preview image comprises n image areas, and the dark area is an image area of which a first brightness value is less than or equal to a preset brightness value in the n image areas; and lightening a first display area corresponding to the dark area on the second screen by using a second brightness value, wherein the first screen and the second screen are arranged at a preset angle. Through the scheme, the terminal equipment can light the first display area corresponding to the dark area on the second screen by the second brightness value under the condition that the dark area exists in the first preview image in the first screen, so that the second screen can be adopted for light supplement, the brightness value of the original dark area in the first preview image can be improved, or the dark area does not exist in the first preview image any more, so that the light and shade difference of different areas in the shot picture is small, and the imaging quality is improved.

Optionally, the second brightness value is a default brightness value. Referring to fig. 2, as shown in fig. 4, after the step S12, the light supplement method according to the embodiment of the present invention further includes the following steps S13 and S14.

S13, the terminal device determines whether there is a dark area in the first preview image.

And S14, the terminal device adjusts the brightness value of the first display area from the second brightness value to the target brightness value.

Wherein the target brightness value is greater than the second brightness value.

In the embodiment of the present invention, after S12, it may be further determined whether a dark region exists in the first preview image, and the brightness value of the first display region is adjusted to be higher when the dark region exists in the first preview image, so that the effect of light supplement may be further confirmed after light supplement is performed through S11 and S12, and when the dark region still exists in the first preview image after light supplement (that is, the effect of light supplement is not good), the brightness value of the first display region is adjusted to be higher, so that the light supplement effect may be further optimized.

Optionally, in this embodiment of the present invention, after S12, it may further be determined whether a current luminance value of an original dark area in the first preview image is too bright, and in a case that it is determined that the current luminance value of the dark area is too bright, the luminance value of the first display area may be further adjusted from the second luminance value to a luminance value that is smaller than the second luminance value and larger than the preset luminance value.

In the embodiment of the present invention, the current luminance value of the dark area in the first preview image may be compared with a luminance threshold to determine whether the current luminance value of the dark area is too bright, and if the current luminance value of the dark area is greater than or equal to the luminance threshold, it may be determined that the current luminance value of the dark area is too bright. It should be noted that, in the embodiment of the present invention, the preset brightness value is smaller than the brightness threshold.

Optionally, with reference to fig. 4, as shown in fig. 5, after the above step S13 and before the step S14, in the case that a dark region exists in the first preview image, the light supplementary method provided by the embodiment of the present invention further includes the following steps S15 and S16.

And S15, the terminal equipment acquires the shooting distance, wherein the shooting distance is the distance between the shooting object and the terminal equipment.

And S16, the terminal equipment determines the brightness value of the target according to the shooting distance.

In the embodiment of the invention, the target brightness value can be determined according to the shooting distance, so that different target brightness values can be determined according to scenes with different shooting distances, and thus, when the first display area is lightened by the target brightness value, the light supplementing effect is better.

Optionally, with reference to fig. 2, as shown in fig. 6, after the step S12, the light supplement method provided by the embodiment of the present invention may include the following steps S17 and S18.

And S17, the terminal equipment receives a first input of the user.

And S18, the terminal equipment responds to the first input and acquires an image.

In the embodiment of the present invention, after the supplementary lighting is performed through the above S11 and S12, the terminal device may be triggered to acquire an image through the first input of the user. Therefore, the image collected by the terminal equipment cannot have the obvious condition that some areas are brighter and other areas are darker, and the quality of the picture collected by the terminal equipment is improved.

Alternatively, referring to fig. 6, as shown in fig. 7, after the step S12 and before the step S17, the light supplement method provided by the embodiment of the present invention may include the following steps S19 and S20.

And S19, the terminal equipment receives a second input of the user.

And S20, the terminal equipment responds to the second input, and the brightness value of the first display area is adjusted to a third brightness value from the second brightness value.

And adjusting the brightness value of the first display area from the second brightness value to the third brightness value, wherein no dark area exists in the first preview image.

In the embodiment of the present invention, after the supplementary lighting is performed through the above S11 and S12, when the user feels that the supplementary lighting effect is not ideal (that is, the user still observes the dark region in the first preview image), the terminal device may be triggered to acquire the image by first triggering the terminal device to adjust the luminance value of the first display region from the second luminance value to the third luminance value through the second input of the user. Therefore, the situation that some areas are brighter and other areas are darker can not occur in the image acquired by the terminal equipment, and therefore the quality of the picture acquired by the terminal equipment can be improved.
