All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A flow chart of the method provided by the embodiment of the present invention is shown in fig. 2, and the method includes:
step S201: and detecting whether the shot object is positioned in the shooting blind area of the electronic equipment.
In the embodiment of the invention, the electronic equipment determines the object positioned in the shooting blind area as the shot object. In a specific application scenario, the object may or may not be an object that the user needs to photograph.
The electronic equipment comprises at least one camera, and after the electronic equipment leaves a factory, the position of the camera in the electronic equipment is fixed, and the shooting range of the camera is also fixed, so that the shooting blind area of the electronic equipment can be determined according to the position of the at least one camera in the electronic equipment and the corresponding shooting range of the at least one camera. Information characterizing the dead zone of the electronic device may be stored in the electronic device.
The information for characterizing the dead zone of the electronic device may include: the relative position of the at least one camera in the electronic equipment and the shooting range of the at least one camera; or, a specific range of the dead zone.
The electronic equipment can detect whether the shot object is located in the shooting blind area of the electronic equipment according to the information for representing the shooting blind area of the electronic equipment.
Step S202: and when the shot object is positioned in the shooting blind area, generating prompt information.
The embodiment of the invention provides a prompting method, which is used for detecting whether a shot object is positioned in a shooting blind area of electronic equipment or not, and generating prompting information when the shot object is positioned in the shooting blind area. Therefore, the user can move the shot object or move the electronic equipment, so that the shot object is not in the shooting blind area, the situation that the shot object is in the shooting blind area is avoided, and the shooting quality of the image is improved.
There are various methods for detecting whether a photographed object is located in a dead zone of the electronic device, and embodiments of the present invention provide, but are not limited to, the following.
The first method is a method for detecting whether a shot object is positioned in a shooting blind area of the electronic equipment.
The dead zone can be simplified to a rectangular parallelepiped, or a plane. Fig. 3 is a schematic diagram of a dead zone corresponding to fig. 1 according to an embodiment of the present invention.
A point where the visible lines of sight of the boundaries of the shooting range of the camera in the electronic device 31 intersect is referred to as a first blind point a. If the side length of the cross section of the electronic device is far smaller than the distance between the first dead zone point a and the electronic device, the dead zone can be simplified into a cuboid (the rectangle shown by the dotted line in fig. 3 is the cross section of the cuboid), or a plane (that is, the side where the electronic device is located in the cuboid is regarded as a point, and the cuboid becomes a rectangular plane).
Since the electronic device in fig. 1 is a cube, one side of the cross section of the electronic device is a straight line, and if the electronic device is not a cube, one side of the cross section of the electronic device may be a curve.
The step of detecting whether the shot object is located in the shooting blind area of the electronic equipment comprises the following steps:
obtaining the distance between the shot object and the electronic equipment;
when the distance is smaller than or equal to a preset value, determining that the shot object is located in the shooting blind area;
and when the distance is larger than the preset value, determining that the shot object is not positioned in the shooting blind area.
The preset value may be a distance between the first blind point a and the electronic device.
Because the shooting blind area can be regarded as a cuboid or a rectangle, the distance between the boundary of each shooting blind area in the shooting blind area and the electronic equipment is equal, and a preset value can be set.
Second, a method for detecting whether a subject is located in a dead zone of the electronic device.
The dead zone cannot be simply regarded as a rectangular parallelepiped or a rectangle. The dead zone is an irregular or regular spatial volume. The dead zone as shown in fig. 1 is a triangular prism.
Still taking two shooting blind areas in fig. 1 as an example, a first distance between the object to be shot and the electronic device when the object to be shot is located at point B is smaller than a second distance between the object to be shot and the electronic device when the object to be shot is located at point C, but the object to be shot is no longer in the shooting blind area when the object to be shot is located at point B, and the object to be shot is located in the shooting blind area when the object to be shot is located at point C, so that whether the object to be shot is in the shooting blind area cannot be determined simply according to the distance between the electronic device. The relative position of the object to be photographed and the electronic device needs to be known.
The step of detecting whether the shot object is located in the shooting blind area of the electronic equipment comprises the following steps:
obtaining the relative position of the shot object and the electronic equipment;
when the relative position belongs to the shooting blind area, determining that the shot object is positioned in the shooting blind area;
and when the relative position does not belong to the blind shooting area, determining that the shot object is not positioned in the blind shooting area.
Preferably, a spatial coordinate system may be set in the electronic device in advance, so that a spatial coordinate range included in the dead zone can be determined. Whether the shot object is positioned in the shooting blind area can be determined according to the calculated space coordinate of the shot object and the coordinate range contained in the shooting blind area.
When the object to be shot is located in the shooting blind area, there are various implementation manners for generating the prompt message, and the embodiments of the present invention provide, but are not limited to, the following.
The first implementation method for generating the prompt message when the object to be shot is located in the shooting blind area comprises the following steps:
when the shot object is located in the shooting blind area, a light effect prompt is output and used for identifying the range of the shooting blind area by using light rays.
Therefore, the user can know which areas in the current space are the shooting blind areas at a glance, and the shot object can be directly enabled to avoid the shooting blind areas.
Secondly, when the object to be shot is located in the shooting blind area, the method for generating the prompt message comprises the following steps:
when the shot object is positioned in the shooting blind area, controlling the display to display the position of the shot object in the shooting blind area.
A display may be included in the electronic device. The display can display the position of the shot object in the shooting blind area.
The electronic device can visually display the position of the shot object in the cross section of the shooting blind area, as shown in fig. 4, which is a schematic diagram of the display provided by the embodiment of the invention for displaying the position of the shot object in the shooting blind area.
Still taking fig. 1 as an example, it is assumed that the cross section of the dead zone is a triangle, and the black point in fig. 4 is the object to be shot. This allows for a very intuitive display to the user.
Of course, the display can also display the space coordinates of the shot object and the space coordinates contained in the shooting blind area where the shot object is located. The display may also show the direction and/or distance that the object being photographed or the electronic device needs to be moved.
Thirdly, when the object to be shot is located in the shooting blind area, the method for generating the prompt message includes:
and when the shot object is positioned in the shooting blind area, controlling the loudspeaker to emit prompt voice.
At this time, the electronic device may include a speaker.
Fourthly, when the object to be shot is located in the shooting blind area, the method for generating the prompt message comprises the following steps:
when the object to be shot is located in the shooting blind area, the LED lamp is controlled to emit light or flicker.
At this time, the electronic device may include an LED lamp.
It is understood that one electronic device may correspond to a plurality of blind shooting areas, and thus, when the object is located in the blind shooting area, controlling the LED lamp to emit light or flash may include:
determining a target shooting blind area where a shot object is located from a plurality of shooting blind areas;
controlling the LED lamp to emit light of a target color corresponding to the target shooting blind area, or controlling the LED lamp to flash with the target color;
or the like, or, alternatively,
each of the blind shooting areas corresponds to an LED lamp, and controlling the LED lamp to emit light or blink when the object is located in the blind shooting area may include:
determining a target shooting blind area where a shot object is located from a plurality of shooting blind areas;
and controlling the LED lamp corresponding to the target shooting blind area to emit light or flicker.
An embodiment of the present invention further provides an electronic device, as shown in fig. 5, which is a schematic structural diagram of the electronic device provided in the embodiment of the present invention, where the electronic device 50 includes:
at least one camera 51; the electronic equipment corresponds to at least one shooting blind area.
Generally, the number of blind shooting zones is related to the number of cameras in the electronic device, the positions set in the electronic device, and the shooting ranges of the cameras.
When the electronic equipment corresponds to a plurality of shooting blind areas, the shooting blind areas are not crossed, namely, the shooting blind areas are separated through a visible area (the area which can be shot by the camera is called the visible area).
Therefore, each blind zone corresponds to at least one distance sensor 52, and each distance sensor 52 is used for detecting the distance between the object located in the self-detection range and the self-detection.
A distance sensor is a sensor that uses the principle of (flying time) to detect the distance of an object.
The processor 53 is configured to, for each of the blind shooting areas, determine whether a shot object is located in the blind shooting area according to a distance detected by at least one distance sensor corresponding to the blind shooting area; and when the shot object is positioned in the shooting blind area, generating prompt information.
The embodiment of the invention provides electronic equipment, wherein a processor 53 can detect whether a shot object is positioned in a shooting blind area of the electronic equipment, and generates prompt information when the shot object is positioned in the shooting blind area. Therefore, the user can move the shot object or move the electronic equipment, so that the shot object is not in the shooting blind area, the situation that the shot object is in the shooting blind area is avoided, and the shooting quality of the image is improved.
In the embodiment of the present disclosure, it is mentioned that the dead zones can be simplified into a rectangular parallelepiped or a rectangle, and each dead zone can correspond to a distance sensor, because it can be determined whether the object is located in the dead zone only according to the distance between the object and the distance sensor (because the distance sensor is disposed on the electronic device, the distance between the object and the electronic device is almost equal to the distance between the object and the distance sensor, and the difference between the two distances is negligible).
At this time, for each blind shooting area, the processor is specifically configured to, when determining whether the object to be shot is located in the blind shooting area according to the distance detected by the at least one distance sensor corresponding to the blind shooting area:
when the distance detected by the distance sensor corresponding to the shooting blind area is smaller than or equal to a preset value, determining that the shot object is located in the shooting blind area;
and when the distance detected by the distance sensor corresponding to the shooting blind area is greater than the preset value, determining that the shot object is not positioned in the shooting blind area.
In the embodiment of the prompting method, the dead zone is an irregular or regular space, and at least two distance sensors are needed to detect the same object to be shot. When the distance sensor is disposed in the electronic device, the relative position between the at least two distance sensors may be stored in the electronic device.
For each blind shooting area, the processor is specifically configured to, when judging whether the object to be shot is located in the blind shooting area according to the distance detected by the at least one distance sensor corresponding to the blind shooting area:
obtaining the relative position of the shot object and the electronic equipment according to the distance detected by the at least two distance sensors corresponding to the shooting blind area and the relative position between the at least two distance sensors;
when the relative position belongs to the shooting blind area, determining that the shot object is positioned in the shooting blind area;
and when the relative position does not belong to the blind shooting area, determining that the shot object is not positioned in the blind shooting area.
Preferably, a spatial coordinate system may be preset, and the spatial coordinates of the object to be photographed may be calculated based on the at least two distance sensors.
There are various methods for the processor to implement "generating the prompting information when the object to be shot is located in the shooting blind area", and for details, refer to four implementation manners of "generating the prompting information when the object to be shot is located in the shooting blind area" in the prompting method, which are not described herein again.
