According to the embodiment of the invention, the corresponding camera can be automatically started according to the environmental state data of the mobile terminal, a user does not need to manually switch the camera, the shooting preparation time is shortened, and the user operation experience is improved.
Referring to fig. 2, a flowchart illustrating steps of another embodiment of a method for starting a camera according to an embodiment of the present invention is shown, and is applied to a mobile terminal, where the mobile terminal has a camera, and the camera includes a front camera and a rear camera, and the method specifically includes the following steps:
In a normal process, when the camera application program is started, a default camera is started, or a corresponding camera is started according to the use state when the camera application program is quitted last time. In the embodiment of the invention, when the camera application program of the mobile terminal is started, the environment state data of the mobile terminal is acquired and is used for starting the corresponding camera according to the environment state data.
In a preferred embodiment of the present invention, the environment status data includes current position data, walking track data and electronic compass data, and the step 202 may include the following sub-steps:
judging whether the mobile terminal is within a preset geographic range or not according to the current position data; the preset geographic range is provided with a designated place;
if the mobile terminal is within a preset geographic range, determining whether a user faces the appointed place or not according to the walking track data and the electronic compass data;
when the user is determined to face the appointed place, starting the rear camera;
and starting the front camera when the user is determined to face away from the designated place.
In the embodiment of the invention, the current position data of a user is acquired, whether the mobile terminal is in a preset geographic range is judged according to the current position data, if yes, whether the user faces to a specified place in the preset geographic range is further determined according to walking track data and electronic compass data, when the user faces to the specified place, the rear camera can be started to shoot according to the condition that the user generally holds the mobile terminal, and otherwise, when the user faces away from the specified place, the front camera can be started to shoot according to the condition that the user generally holds the mobile terminal and the front camera generally faces to the specified place.
The preset geographic range may be an electronic fence, the electronic fence is a scenic spot area drawn on a map, and the specified location may be a scene in the scenic spot area. The embodiment of the invention can judge whether the user is in the scenic spot area according to the current position data of the user, if so, the walking track data of the user in the scenic spot area is further called, the electronic compass information of the mobile phone and the position information of each scenery in the scenic spot area are combined to comprehensively judge whether the user faces the scenery, and if so, the rear camera is opened. And if the back of the scenery is opposite to the scenery, opening the front camera.
For example, assume that a user enters a sight area and looks from the field door in the sight area to the west along the east-west direction. According to the position information of the scenery in the scenic spot area, a Buddha exists at a position 1 kilometer high in the north of the scenic path. And (3) taking the mobile phone out by the user to enter a camera application program, and pointing the electronic compass of the mobile phone to the north, wherein the mobile phone is positioned between the user and the Buddha image, and then directly switching to the rear camera. If the electronic compass points to the south, the mobile phone is moved to the edge side of the user and the Buddha, and then the mobile phone can be switched to the front camera to take self-shooting.
In a preferred embodiment of the present invention, the environment state data includes a first illumination brightness corresponding to a front camera viewing area, and a second illumination brightness corresponding to the rear camera viewing area is obtained, and the step 202 may include the following sub-steps:
when the first illumination brightness is larger than or equal to the second illumination brightness, starting the rear camera;
and when the first illumination brightness is smaller than the second illumination brightness, starting the front camera.
After the camera application program is started, the photosensitive sensor can be started to judge the illumination brightness of the viewing area of the front camera and the rear camera, and the side with better light can be automatically switched to use by comparing the two illumination brightness.
For example, suppose a user eats at a dim restaurant, the light around the table is poor, and the light on the table is good. The user takes out the mobile phone, and the rear camera is aligned with the dining table to prepare for shooting the table gourmet. After the camera application program is entered, the illumination brightness acquired through the photosensitive sensor shows that the light of the viewing area of the front camera is poor, the camera is automatically started to view the rear camera, and a user waits for shooting.
In a preferred embodiment of the present invention, the environmental status data includes first image data acquired by a front camera and second image data acquired by a rear camera, and the step 202 may include the following sub-steps:
extracting first image characteristic data from the first image data, and extracting second image characteristic data from the second image data;
comparing the first image characteristic data with a preset image database to determine the number of first similar images, and comparing the second image characteristic data with an on-line image database to determine the number of second similar images;
when the number of the second similar images is larger than or equal to the number of the first similar images, starting the rear camera;
and when the number of the second similar images is less than the number of the first similar images, starting the front camera.
When the camera application program is started, the front camera and the rear camera are started at the same time, images are collected by the two cameras respectively, image characteristic data are extracted from image data collected by the front camera and the rear camera respectively, and the image characteristic data can comprise characteristic data such as a head portrait, a tree, sky, ground and the like.
In the embodiment of the invention, the image characteristic data of the first image collected by the front camera is compared with the preset image database to determine the images similar to the first image collected by the front camera and count the number of the first similar images, and meanwhile, the image characteristic data of the second image collected by the rear camera is compared with the preset image database to determine the images similar to the second image collected by the rear camera and count the number of the second similar images.
When the number of the second similar images is larger than or equal to the number of the first similar images, the mobile phone user or most users prefer to shoot scenes such as sky, ground and the like, and then the rear camera can be started.
When the number of the second similar images is smaller than that of the first similar images, the mobile phone user or most users prefer to take a self-timer, and then the front-facing camera can be started.
In one example, the user opens the camera application, frames the images with the front camera and the rear camera to obtain the images, and at this time, the images can be matched with the online image database, and the tendency of using the front/rear camera is presumed according to the shooting habits of most users in the online image database, so that the switching is automatic. In addition, it is also possible to determine which camera to use for album data local to the user that has been categorized into tags.
For example, when a user lifts up a mobile phone and the rear camera is aligned with the sky, the front camera and the rear camera perform framing and imaging to obtain an image, the framing result of the rear camera is the sky and the white clouds, and the framing result of the front camera is the earth and the face. And performing feature extraction on the images of the front camera and the rear camera to obtain image feature data, comparing the image feature data with the big data of the user in the online image database, and if more users shoot sky cloudiness are found, considering that the user should tend to open the rear camera for shooting at present, and switching the camera to use the rear camera.
Similarly, if the preset image database is the local photo album of the user, and the local photo album mostly mainly includes landscapes and other object images, the user is considered not to be used for self-shooting, and the rear camera is automatically switched.
And 203, if a switching instruction of the camera is received, switching the camera according to the switching instruction.
In practical application, if it is possible that the currently-started camera is not the camera required by the user, a corresponding switching instruction may be generated according to the operation of the user, and the camera may be switched based on the switching instruction.
By applying the embodiment of the invention, the switching of the cameras can be automatically carried out, the operation of a user is simplified, and the operation experience of the user is improved.
In order that those skilled in the art may better understand the embodiments of the present invention, the advantages of the embodiments of the present invention will be described below using specific examples. Referring to fig. 3, a flowchart for a user to start a camera normally for shooting is described, but in the embodiment of the present invention, an automatic identification scheme is inserted on the basis of the above flowchart to identify the current environment of the user or the usage habits of the user, so as to start a camera that is currently most suitable for the user, so that after the user starts a camera application program, the intelligent switching between a front camera and a rear camera can be realized without manual operation of the user, and specifically, reference may be made to fig. 4.
