The focusing method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1, a flowchart illustrating steps of a focusing method according to an embodiment of the present application is shown.
The focusing method of the embodiment of the application comprises the following steps:
step 101: and in the case of detecting that the light-emitting point is included in the shooting preview picture, determining the position of the light-emitting point.
Wherein, the luminous point is formed by the light ray emitted by the target device acting on the shooting object.
The target device may be a light-emitting device included in the electronic device, and may also be a light-emitting intelligent device having a connection relationship with the electronic device. The target device can be integrated with a light emitting device, the light emitting device can emit light with preset colors, and the light with the preset colors emitted by the light emitting device forms light emitting points in a shooting preview picture. Furthermore, an infrared laser emitting and receiving device may be integrated in the target device, and a light emitting point is formed in the photographing preview screen by infrared light emitted from the infrared laser emitting and receiving device.
The light-emitting point included in the shooting preview picture can be a newly added light-emitting point, and can also be a light-emitting point which moves from other positions in the shooting preview picture to the current position.
Step 102: and determining the shooting object at the position as a focusing object.
As shown in fig. 2, the image of the photographed preview image includes two objects, i.e., an oval object a and a hexagonal object B, and the user controls the touch device to emit light and positions the light-emitting point on the photographed object a, so that the light-emitting point appears on the image of the hexagonal object B in the photographed preview image synchronously, and the hexagonal object B is determined as the object to be focused.
Step 103: and adjusting the shooting focus to the focusing object.
In the step, the system automatically controls the camera to adjust the focusing without touching the screen of the electronic equipment or moving the body of the electronic equipment by a user to adjust the focusing object.
According to the focusing method provided by the embodiment of the invention, the position of the luminous point is determined under the condition that the shooting preview picture is detected to include the luminous point, wherein the luminous point is formed by the action of light rays emitted by a target device on a shooting object; determining the shooting object at the position as a focusing object; and adjusting the shooting focus to the focusing object. The user can specify the focusing object in the shooting preview picture through the light emitted by the target device, and does not need to touch the screen of the electronic equipment or move the body of the electronic equipment to adjust the focusing object, so that the operation is convenient and fast.
In an optional embodiment, in a case that it is detected that the light-emitting point is included in the shooting preview screen, the determining a manner of the position of the light-emitting point includes the following steps:
the method comprises the following steps: determining a first color of a light-emitting point in the case of detecting that the light-emitting point is included in the shooting preview picture;
step two: and determining the position of the light-emitting point in the shooting preview picture under the condition that the light-emitting color of the target device comprises the first color.
For example: the target device can emit red light and green light, and the detected first color of the luminous point in the shooting preview picture is blue, the luminous point is determined to be not used for triggering focusing, and therefore the step one is returned to continuously detect the shooting preview picture.
For another example: the target device can emit red light and green light, and the detected first color of the luminous point in the shooting preview picture is red, the luminous point is determined to be used for triggering focusing, so that the position of the luminous point in the shooting preview picture is determined, and a subsequent related focusing process is executed.
Under the condition that the light color emitted by the target device does not contain the first color, the light-emitting point is determined to be not the light-emitting point formed by the light emitted by the user control target device but the light-emitting point formed by the light emitted by other external light-emitting objects, so that the subsequent focusing related flow is not required to be executed.
The mode of optionally judging whether the color of the light-emitting point is matched with the color of the light emitted by the target device can effectively avoid blindly adjusting the focusing object, and avoid interference brought to users and useless work caused to electronic equipment.
In an optional embodiment, in a case where the light-emitting color of the target device includes a first color, the step of determining the position of the light-emitting point in the shooting preview screen includes the following sub-steps:
the first substep: comparing whether the first color and a second color of the shooting object at the position of the luminous point belong to the same color system or not under the condition that the luminous color of the target device comprises the first color;
in order to improve the focusing accuracy, in the case that the focusing object is red, the user can control the target device to emit green light to form a light-emitting point on the focusing object. In the case where the object in focus is green, the user may control the target device to emit red light to form a light emitting point on the object in focus.
And a second substep: when the color difference is not of the same color system, the light-emitting point is regarded as an effective point.
In the case of belonging to the same color system, the light-emitting point is regarded as an invalid point. When the light emitting point is recorded as the effective point, the subsequent focusing-related operation is executed, when the light emitting point is recorded as the ineffective point,
for example: the target device can emit red light and green light, the detected first color containing the light-emitting point in the shooting preview picture is red, the shooting object at the position of the light-emitting point is green, the first color and the detected first color are determined to belong to different color systems, and the light-emitting point is marked as an effective point, wherein the effective point is used for the light-emitting point formed by the light emitted intentionally through the target device. The invalid point refers to a light-emitting point formed by a light ray which is not intended to be emitted by the target device by the user or a light-emitting point formed by a light ray which is not intended to be emitted by the target device.
The mode of optionally judging whether the luminous point is the effective point can improve the accuracy of identifying the focusing object, thereby further effectively avoiding the interference brought to users and the useless work caused to the electronic equipment due to blind adjustment of the focusing object.
In an optional embodiment, the target device includes an infrared laser transceiver, the target device emits infrared laser, and the step of determining the position of the light-emitting point when detecting that the light-emitting point is included in the shooting preview picture includes the following sub-steps:
the first substep: under the condition that the shooting preview picture is detected to include the luminous point, determining the time difference between the first time when the target device emits the infrared laser and the second time when the shooting preview picture is detected to have the luminous point;
the electronic equipment is also provided with an infrared laser receiver, the infrared laser receiver can receive infrared laser reflected by a focusing object at the position of the luminous point, the first time when the target device sends the infrared laser is reached, and the time difference between the first time and the second time when the infrared laser receiver arranged in the electronic equipment receives the infrared laser can be represented by Tb.
And a second substep: determining a first distance between the target device and a shooting object at the position of the light-emitting point;
an infrared laser receiving and transmitting device in the target device transmits infrared laser, and the transmitted infrared laser is reflected after encountering an obstacle and then is received by the target device again. The target device can determine a first distance between the target device and a shooting object at the position of the light-emitting point through the time difference of the red and red infrared laser lights.
Specifically, the time difference between the emission and the emission of the infrared laser light can be represented by Ta, c represents the light speed of the infrared laser light, and a represents the first distance, so that the first distance a is (Ta/2 × c).
And a third substep: determining a second distance between the camera and the shooting object according to the time difference and the first distance;
as shown in fig. 3, the first distance, i.e., distance a shown in fig. 3, and the second distance, i.e., distance b shown in fig. 3, may be determined by the formula b ═ Tb × c-a.
And a fourth substep: and determining the position of the light-emitting point according to the second distance.
After the second distance between the camera of the electronic equipment and the shot object is determined, the electronic equipment can control the camera to adjust the focusing distance, focus is aligned to the shot object, namely the focusing object, and focusing is automatically completed.
The mode of optionally selecting the focusing object through the infrared laser has convenient and accurate operation.
In an optional embodiment, in a case that the shooting preview picture includes the light-emitting point, before determining the position of the light-emitting point, the method may further establish a data transmission connection with the target device in a case that the shooting function is detected to be turned on.
After the data transmission connection is established between the electronic equipment and the target device, the electronic equipment is convenient to communicate with the target device in real time.
