A focusing method provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Fig. 1 illustrates a focusing method provided by an embodiment of the present invention, which may be performed by an electronic device, and the electronic device may include: the system comprises a server and/or a terminal device, wherein the terminal device can be a mobile phone, a tablet computer, a vehicle-mounted terminal and the like. The method may be performed by software or hardware installed in an electronic device, the method comprising the steps of:
s104: and acquiring a preview image acquired by the camera.
In this embodiment of the application, the preview image may be acquired by a camera of the electronic device. The preview image may include a first area and a second area, the first area in the preview image having a brightness greater than a brightness of the second area in the preview image, the second area being an image area of the preview image other than the first area.
Specifically, the first region and the second region in the preview image may be divided by a preset first luminance value by presetting the first luminance value, for example, a region in the preview image having a luminance greater than or equal to the first luminance value is the first region, and a region in the preview image having a luminance less than the first luminance value is the second region. The designer can reasonably determine the first brightness value according to the model and the parameters of the camera, and the specific size of the first brightness value is not limited in the embodiment of the application.
In one implementation, the electronic device obtains a preview image acquired by a camera, where the preview image may include a face image. The preview image may also include a landscape image in the preview mode, and the like, and the electronic device divides the face image or the landscape image in the preview mode acquired by the camera into luminance regions, and takes a region with higher luminance in the preview image, such as the face image in the preview mode, the landscape image in the preview mode, and the like, as a first region, and takes other image regions except the first region as a second region, and the luminance of the first region is greater than that of the second region.
In the first embodiment, in a low-light environment, a user wants to shoot a landscape picture, the user opens a camera of the electronic device, the camera is enabled to be directed at the landscape to be shot to obtain a preview image, the electronic device can acquire a landscape image in a preview mode collected by the camera, the landscape image in the preview mode has a first landscape area and a second landscape area with different brightness, the second landscape area is a landscape area except the first landscape area in the landscape image, the brightness of the first landscape area is greater than that of the second landscape area, the first landscape area can be used as the first area, and the second landscape area is used as the second area. In a low-light environment, when a landscape is shot, a first landscape area with higher brightness is searched in a landscape image in a preview mode, the first landscape area is higher in brightness, so that focusing is easier to achieve successfully, the first landscape area is used as a focusing area for focusing, and the whole landscape to be shot can be shot after the focusing is successful.
In the second embodiment, in a low-light environment, a user wants to use a camera to perform self-shooting, the user opens the camera of the electronic device to collect a face image in a preview mode, and the brightness of the face contour is insufficient due to weak light, so that the contour of the face image in the preview mode is blurred, but in this case, the light reflection capability of the eye region is higher than that of other face regions except the eye region, so the eye region has higher brightness and can be used as the first region, and the other face regions are used as the second region.
S106: and controlling the camera to focus on the first area.
In the step, the first area with higher brightness is used as a focusing area for focusing. The first area may be the first scenery area or the eye area mentioned in the different embodiments above, and the electronic device may control the camera to focus on the first scenery area or the eye area. Specifically, the electronic device can control the camera to lock the focusing areas on the high-brightness areas by identifying the first areas with higher brightness, namely the first landscape areas or the eye areas, so that focusing of the whole shooting process can be realized by focusing the high-brightness areas, and finally the shooting definition in a low-light environment can be improved.
For the first embodiment described above, after it is determined that the first landscape area with higher brightness is the first area and the second landscape area with lower brightness is the second area, the electronic device controls the motor to start, so that the motor controls the lens of the camera to move, and then the first landscape area is used as the focusing area for focusing, so that focusing of the first landscape area is easier to achieve in a low-light environment, and the camera of the electronic device can shoot a clearer landscape picture.
For the second embodiment, when the eye region with high brightness is determined to be the first region, the electronic device controls the motor to start, so that the motor controls the lens of the camera to move, and the camera focuses by using the eye region as a focusing region, thereby easily realizing successful focusing in a low-light environment, and further facilitating the electronic device to take a relatively clear face picture in the low-light environment.
The embodiment of the invention discloses a focusing method different from a conventional focusing mode. According to the scheme, the first area with higher brightness is selected as the focusing area for focusing when shooting is carried out in a low-light environment, the focusing area is easier to determine due to the fact that the first area is higher in brightness, and then focusing can be easier and successful by taking the first area as the focusing area. Therefore, the focusing method disclosed by the embodiment of the application can realize focusing under a low-light environment more easily. Therefore, the focusing method disclosed by the embodiment of the application can solve the problem that the electronic equipment is difficult to focus the shot object in a low-light environment.
In an application scene, in a low-light environment, when a user takes a picture, the outline of a face image collected by a camera on electronic equipment is fuzzy, at the moment, the camera can identify the eye region of the face with high brightness, so that the electronic equipment can control the camera to focus on the eye region, and the focusing on the whole face region is realized. Therefore, the focusing method disclosed by the application can solve the problem that the electronic equipment is difficult to focus due to insufficient human face brightness in a low-light environment.
As described above, in the actual focusing process, it is necessary to acquire the preview image first, and then determine the first region with higher brightness in the preview image. However, due to the low brightness of the light, it may be difficult for the camera to acquire a preview image that is as desired. Based on this, please refer to fig. 2, in a further alternative, before S104, the focusing method disclosed in the embodiment of the present application may further include:
s102: and controlling the light supplementing element to supplement light under the condition that the brightness of the shooting environment is less than a preset brightness threshold value.
Here, when the brightness of the shooting environment is too low to affect the acquisition of the preview image, the light supplement element is controlled to implement light supplement so as to facilitate the acquisition of the preview image. It should be noted that the light supplement direction of the light supplement element is the same as the shooting direction of the camera, that is, the light supplement element should supplement light to the object to be shot, so as to more easily acquire the preview image.
The electronic equipment can be configured with a brightness sensor, the brightness sensor is used for detecting the brightness of the environment, before the electronic equipment acquires the preview image collected by the camera, the electronic equipment detects the brightness of the surrounding shooting environment through the brightness sensor, then, under the condition that the brightness of the shooting environment is smaller than a preset brightness threshold, the light supplement of the light supplement element is controlled, and the preset brightness threshold can be set in advance according to the performance of the electronic equipment by a person skilled in the art and can also be determined according to multiple experiments.
In an application scene, under the condition that the brightness of a shooting environment is smaller than a preset brightness threshold value, an electronic device can utilize a light supplementing element to supplement light, the light supplementing element can be a screen, a flash lamp or an external light supplementing device of the electronic device, of course, the light supplementing direction of the light supplementing element needs to be consistent with the shooting direction of a camera of the electronic device, and then effective light supplementing can be carried out on a shot object, and further the collection of subsequent preview images is facilitated.
In an alternative embodiment, S102 may include adjusting the brightness of the screen, the orientation of the screen being in accordance with the shooting direction. Specifically, adjusting the screen brightness is achieved by increasing the screen brightness. Under the condition, the increase of the screen brightness is more beneficial to realizing light supplement at a short distance, so that the light supplement is realized by adjusting the screen brightness, and the application in a close-range shooting (for example, self-shooting) scene is more beneficial.
In another alternative embodiment, S102 may include controlling flash fill light, the flash being oriented in the same direction as the shooting direction. Specifically, the flash light supplementary lighting is controlled by turning on the flash light or increasing the power of the flash light. Under the condition, the flash lamp is started or the brightness of the flash lamp is increased, so that the light supplement at a longer distance is more favorably realized, and the application under a long-range shooting scene is more favorably realized.
Specifically, the electronic device controls the light supplement element to supplement light, and the electronic device can supplement light by adjusting the brightness of the screen, controlling the on and off of the flash lamp, controlling the power of the flash lamp, or controlling the on and off of the peripheral lighting device.
Optionally, when the brightness of the surrounding environment is weak and the face of the user is far away from the screen, after the light is supplemented to the face of the user through the screen of the electronic device, the camera collects preview images more easily, but face images collected by the camera are still fuzzy, at this time, compared with the face area, the eye area of the user has stronger light reflection capability to the screen, so that the electronic device can control the camera to focus on the eye area, and finally the success rate of focusing the face by the camera of the electronic device is improved to a certain extent.
Optionally, in a low-light environment, when a user uses a rear camera of the electronic device to shoot a certain landscape, the electronic device may control the flash lamp to turn on, so as to implement light supplement of the flash lamp to the landscape, and further enable the camera to more easily acquire a preview image, and further implement that the brightness of a certain landscape area is higher than that of other landscape areas, and therefore, a basis is provided for the electronic device to control the camera to successfully focus by using light supplement energy of the light supplement element.
In a further technical solution, please refer to fig. 3, S106 may include the following steps:
s1061: and controlling the camera to focus by taking the first sub-area as a focusing area.
In S1061, the first region may be further subdivided, and the first region may include a first sub-region and a second sub-region, and the brightness of the first sub-region is greater than that of the second sub-region. The second sub-area is an image area of the first area other than the first sub-area.
Alternatively, the first sub-region and the second sub-region in the first region may be divided by a preset second luminance value by presetting the second luminance value, for example, a region having luminance greater than or equal to the second luminance value in the first region is the first sub-region, and a region having luminance less than the second luminance value in the first region is the second sub-region. Note that the second luminance value is larger than the first luminance value.
In this embodiment, the camera can be controlled to further focus by taking the first sub-area with higher brightness in the first area as the focusing area, and this multi-level mode of taking the highlight area as the focusing area can further improve the success rate of focusing in a low-light environment.
Taking a photographed person as an example, when a user takes a self-portrait and the surrounding light is weak, if the eye region of the user is the first region, the eyeball region of the eye region can reflect light better, so the eyeball region brightness of the eye region is higher, and the eyeball region is the first sub-region.
As described above, in S106, the camera is controlled to focus on the first area. There are various specific focusing manners, for example, S106 may include: and controlling the camera to carry out phase focusing or contrast focusing by taking the first area as a focusing area.
