[0019] An embodiment of the present invention provides a method for supplementary lighting for shooting and an electronic device. The method for supplementary lighting for shooting is applied in an electronic device.

[0020] See also Figure 1 , Figure 1 A schematic structural diagram of the back side of an electronic device provided by an embodiment of the present invention.

[0021] The electronic device 100 includes a camera 1, at least one light-emitting unit 2, and a transparent back cover 3 covering the camera 1 and the at least one light-emitting unit 2, wherein the transparent back cover 3 can transmit light emitted by the at least one light-emitting unit 2.

The transparent back cover 3 covers the back of the electronic device 100 as a whole, and in addition to covering the camera 1 and the at least one light-emitting unit 2, it also covers other areas on the back of the electronic device 100.

[0022] The back side of the electronic device 100 is the side opposite to the display screen of the electronic device.

[0023] See also Figure 2 , Figure 2 A schematic diagram of the flow of the shooting fill-in light method provided in one embodiment of the present invention.

[0024] 201. After starting the camera software, determine the light emission information of the at least one light emitting unit for shooting fill light, wherein the light emission information includes a light emission area and / or a light emission parameter, and the light emission parameter includes at least one of brightness and color temperature.

[0025] 202. Control at least part of the at least one light-emitting unit 2 to emit light according to the light-emitting information, so as to provide fill light during shooting.

[0026] Therefore, a shooting fill light method provided by an embodiment of the present invention determines the luminous information used for shooting fill light, and then controls at least one of the light-emitting units 2 to emit light according to the luminous information to provide fill light when shooting, rather than only controlling a single flash to provide fill light. This enables multiple fill light effects when shooting, thereby making the fill light effect better and satisfying the user's multiple fill light needs when shooting.

[0027] In some embodiments, the opening of the camera software may include: opening the camera software in response to an operation of opening the camera software, wherein the operation may include an operation of clicking an application icon of the camera software, an operation of opening a camera function in certain functional software, and the like.

[0028] The camera software is software in the electronic device 100 that can be used for shooting.

[0029] The at least one light emitting unit 2 includes a plurality of light emitting units 2 , and the arrangement areas of the plurality of light emitting units on the back side of the electronic device 100 do not overlap.

[0030] The light-emitting area may be a light-emitting unit selected to emit light, or may be a partial light-emitting area in a light-emitting unit selected to emit light.

[0031] Wherein, the "determining the light emission information of the at least one light emitting unit for shooting fill light" may include: determining the selected light emitting unit 2 for fill light and its corresponding light emission parameters, or only determining the light emission parameters, or only determining the light emission area. The "controlling at least part of the at least one light emitting unit 2 to emit light according to the light emission information to perform fill light when shooting" may include: when determining the selected light emitting unit 2 for fill light and its corresponding light emission parameters, controlling the determined light emitting unit 2 for fill light to emit light with the corresponding light emission parameters; or, when only determining the light emission parameters, controlling all the light emitting units 2 to emit light with the determined corresponding light emission parameters; or, when only determining the light emission area, controlling the determined corresponding light emission area to emit light with the default light emission parameters.

[0032] See also Figure 3 , Figure 3 An embodiment of the present invention provides Figure 2 Sub-flow chart of step 201 in FIG.

[0033] 301. Obtain a preview shooting picture.

[0034] 302. Divide the preview shot picture into a first number of picture areas.

[0035] 303. Detect the brightness of each picture area, and determine the light emitting information according to the brightness of each picture area.

[0036] Specifically, in some embodiments, each picture area corresponds to a preset brightness, and each picture area also corresponds to a certain luminous area, wherein the luminous area corresponding to each picture area can be a certain luminous unit, or a luminous area of ​​a certain part of the luminous unit. The "determining the luminous information according to the brightness of each picture area" includes: judging whether the brightness of each picture area is lower than its corresponding preset brightness, and when the brightness of the picture area is lower than its corresponding preset brightness, determining the corresponding luminous area according to the correspondence between the preset picture area and the luminous area, and determining the luminous parameters of the luminous area corresponding to the picture area according to the difference between the current brightness of the picture area and its corresponding preset brightness. Furthermore, at least part of the at least one luminous unit 2 is controlled to emit light according to the determined luminous information, so that the picture area with darker brightness is supplemented with light.

[0037] The preview shooting picture is the shooting picture currently captured by the camera 1, and the electronic device 100 also includes a display screen. When the camera software is turned on, the preview shooting picture will be displayed on the display screen.

[0038] In some embodiments, the first number is a parameter obtained according to the preview shot picture. In other embodiments, the first number is a preset fixed parameter value.

[0039] Therefore, a method for shooting fill-in light provided by an embodiment of the present invention can determine different luminous information according to the brightness of different picture areas in the preview shooting picture, that is, determine the luminous units required for fill-in light and the brightness and color temperature of the light emitted according to the brightness of different picture areas in the preview shooting picture. Then, the selected luminous units for fill-in light are controlled to emit light at the corresponding brightness and color temperature. Compared with the prior art that simply controls the flash near the camera 1 in the electronic device 100 to turn on to complete the fill-in light, a method for shooting fill-in light provided by an embodiment of the present invention can perform fill-in light in a targeted manner according to the conditions of different preview shooting pictures. For example, when it is detected that the brightness of a certain picture area is relatively dark, the corresponding luminous unit 2 is controlled to emit light at a certain brightness and color temperature, and the picture area with darker brightness is specifically filled with light, while the position with brighter brightness or appropriate brightness will not change much. Therefore, a method for shooting fill-in light provided by an embodiment of the present invention can achieve multiple fill-in light effects during shooting, and the fill-in light effect is better, meeting the diversified fill-in light needs of users during shooting.

[0040] In some embodiments, the method further includes: extracting image features in the preview shot picture.

[0041] The “dividing the preview shot screen into a first number of screen areas” includes: dividing the preview shot screen into a first number of screen areas according to the image features in the preview shot screen, wherein the first number is obtained according to the image features in the preview shot screen.

[0042] The image features include identifiable people, objects and scenes in the preview shot image.

[0043] Specifically, in some embodiments, when the image features in the preview shot picture include a person and a scene, each picture area divided in the preview shot picture may be a separate person or scene, each picture area corresponds to a different preset brightness, and the preset brightness of the picture area including the person is higher than the preset brightness of the picture area including the scene, and each picture area also corresponds to a certain luminous area, wherein the luminous area corresponding to each picture area may be a certain luminous unit, or a luminous area of ​​a certain part of the luminous unit. The "determining the luminous information according to the brightness of each picture area" includes: judging whether the brightness of each picture area is lower than its corresponding preset brightness, when the brightness of the picture area is lower than its corresponding preset brightness, determining the corresponding luminous area according to the preset correspondence between the picture area and the luminous area, and determining the luminous parameters of the luminous area corresponding to the picture area according to the difference between the brightness of the current picture area and its corresponding preset brightness. Therefore, controlling at least part of the at least one luminous unit 2 to emit light according to the determined luminous information can make the brightness of the portrait in the preview shot picture higher than the brightness of the scene.

[0044] Therefore, a method for shooting fill-in light provided by an embodiment of the present invention can determine different luminous information according to the brightness of different picture areas in the preview shooting picture and the image features, and then control the selected light-emitting unit 2 for fill-in light to emit light at the corresponding brightness and color temperature. For example, if the image features in the current preview shooting picture include people and scenery, and the brightness of the picture areas including people and scenery are both relatively dark, then the corresponding light-emitting unit 2 is controlled to emit light at a certain brightness and color temperature, and the amount of fill-in light obtained by the picture area including people with darker brightness is targeted to be greater than the amount of fill-in light obtained by the picture area including scenery with darker brightness, so that the picture fill-in light effect presented in the preview shooting picture is better and more aesthetic. Therefore, a method for shooting fill-in light provided by an embodiment of the present invention can meet the diversified fill-in light needs of users when shooting.

[0045] In some other embodiments, the “dividing the preview shot screen into a first number of screen areas” includes: dividing the preview shot screen into a first number of screen areas according to a preset area division method, wherein the first number is a preset value.

[0046] The preset area division method includes dividing the preview shooting screen into equally divided rectangular screen areas.

[0049] 402. Determine the light emitting information according to the currently acquired shooting related information.

[0050] The shooting related information includes at least one of the following: the ambient brightness, the photographed object, and the shooting scene. The ambient brightness is the ambient brightness of the current shooting, the photographed object is the person, scene, or object currently being photographed, and the shooting scene includes a portrait shooting scene mode, a landscape shooting scene mode, or an object image shooting scene mode.

[0051] In some embodiments, the step 402 of "determining the luminous information based on the current shooting related information obtained" may include: determining the luminous information corresponding to the shooting related information based on the current shooting related information obtained, and the correspondence between the shooting related information and the luminous information.

[0052] In some embodiments, when the shooting related information includes the ambient brightness, the difference between the current ambient brightness and the preset ambient brightness has a corresponding relationship with the luminous area and the luminous parameters selected for luminescence. The “determining the luminous information according to the acquired current shooting related information” includes: when the ambient brightness is lower than the preset ambient brightness, determining the luminous area and the luminous parameters selected for luminescence according to the difference between the ambient brightness and the preset ambient brightness.

[0053] In some embodiments, when the shooting related information includes the photographed object, the type of the current photographed object corresponds to the luminous area and luminous parameters selected for luminescence, for example, when the photographed object is a person, the number of luminous areas selected for luminescence is greater than when the photographed object is a scene, and the brightness of the luminous parameters selected when the photographed object is a person is brighter than the brightness of the luminous parameters selected when the photographed object is a scene. The "determining the luminous information based on the currently acquired shooting related information" includes: determining the luminous area and luminous parameters selected for luminescence based on the type of the current photographed object.

[0054] In some embodiments, when the shooting related information includes the shooting scene, the current shooting scene has a corresponding relationship with the light-emitting area and the light-emitting parameters selected for emission. For example, the shooting scene includes night scenes, day scenes, etc. When the shooting scene is a night scene, the number of light-emitting areas selected for emission is greater than the number of light-emitting areas selected for emission when the shooting scene is a day scene, and the brightness of the light-emitting parameters selected when the shooting scene is a night scene is brighter than the brightness of the light-emitting parameters selected when the shooting scene is a day scene. The "determining the light-emitting information based on the current shooting related information obtained" includes: determining the light-emitting area and the light-emitting parameters selected for emission based on the type of the shooting object.

[0055] Therefore, the method for shooting fill-in light provided by the embodiment of the present invention can also determine the light information according to at least one of the ambient brightness, the object being shot, and the shooting scene, and control at least part of the at least one light-emitting unit 2 to emit light according to the light information, so that the picture fill-in light effect presented in the preview shooting picture is better than the fill-in light effect obtained by controlling a single flash. Therefore, the method for shooting fill-in light provided by the embodiment of the present invention can meet the diversified fill-in light needs of users when shooting.

[0056] In some embodiments, when the shooting related information includes ambient brightness, acquiring the current shooting related information includes: detecting the current ambient brightness through a brightness sensor.

[0057] In some embodiments, when the shooting related information includes a photographed object, obtaining the current shooting related information includes: identifying the preview shooting picture to identify the photographed object.

[0058] In some embodiments, when the shooting related information includes the photographed object, obtaining the current shooting related information includes: responding to the user's setting operation on the shooting scene, determining the shooting scene set by the user and obtaining the shooting scene.

[0059] Among them, the "responding to the user's setting operation on the shooting scene, determining the shooting scene set by the user and obtaining the shooting scene" includes: detecting whether the user clicks on the shooting scene setting icon; when it is detected that the user clicks on the shooting scene setting icon, controlling the display of a shooting scene setting page, wherein the shooting scene setting page includes options for different shooting scenes; detecting whether the user clicks on the option of any shooting scene in the shooting scene setting page; when it is detected that the user clicks on the option of any shooting scene in the shooting scene setting page, determining the current shooting scene according to the shooting scene option selected by the user.

[0060] In some other embodiments, the step of determining the luminous information includes: determining the luminous information in response to a user's setting operation on the luminous information.

[0061] 501. When it is detected that a user clicks on the fill light control icon, a fill light setting interface is controlled to be displayed, wherein the fill light setting interface includes selectable light-emitting area options and / or light-emitting parameter options.

[0062] 502. In response to a user's selection operation on a luminous area option and / or a luminous parameter option, determine a corresponding luminous area and / or luminous parameter.

[0063] Therefore, the shooting fill-in light method provided by the embodiment of the present invention can determine the light-emitting information according to the shooting scene selected by the user and the detected ambient brightness and the photographed object.

[0064] When the user selects the luminous area option and the luminous parameter option, determining the current luminous information includes: determining the selected luminous unit 2 for fill light and its corresponding selected luminous parameters as the current luminous information.
