Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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.
For convenience of description, some terms related to the embodiments of the present invention are explained below:
a shooting view field: which is used to indicate the maximum range that the camera can take.
OIS: optical Image Stabilization, refers to compensating for Image blur caused by motion through relative movement of a lens and an Image sensor. For example, referring to fig. 1 to 3, the light 30 is emitted to the image sensor 10 through the lens 20, and the image sensor 10 and the lens 20 may be relatively translated, so that an image shift caused by hand trembling or the like may be compensated.
Specifically, the relative movement between the lens and the image sensor may include lens fixation, image sensor movement, or image sensor fixation, lens movement, and the like.
And (4) image circle: which refers to the effective imaging area of the optical image of the subject being photographed. For example, referring to fig. 4, when an image is captured, the image sensor 10 (i.e., the image recording area) is usually located in the center area of the image circle 40, i.e., the center point of the image sensor 10 and the center point of the image circle 40 coincide. Specifically, by moving the image sensor 10 or the lens, the relative positions of the image sensor 10 and the image ring 40 can be changed, for example, see fig. 5 to 8.
The embodiment of the invention provides a photographing method which is applied to a mobile terminal, wherein a camera of the mobile terminal comprises a target component with a moving property, namely the position of the target component can be moved, and the target component comprises a lens or an image sensor of the camera. Referring to fig. 9, fig. 9 is a flowchart of a photographing method according to an embodiment of the present invention, as shown in fig. 9, including the following steps:
In an embodiment of the present invention, the first input may be a drag input, a slide input, or the like. Specifically, the first input of the user on the shooting preview interface, for example, the input of the user dragging the shooting identifier on the shooting preview interface, or the input of the user sliding on the shooting preview interface, or the input of multiple clicks on the shooting preview interface, may be received in a state that the preview image of the first shooting field of view is displayed on the shooting preview interface of the mobile terminal.
Optionally, the step 901, that is, the receiving of the first input of the user on the shooting preview interface, includes:
receiving a first input of dragging the photographing identifier on the photographing preview interface by a user;
or receiving a first input of sliding of a user in a preset area on the shooting preview interface.
In the embodiment of the present invention, the photographing identifier may be a photographing button, a photographing control, and the like on the photographing preview interface, and the preset area on the photographing preview interface may be reasonably set according to an actual situation, for example, a rectangular area at a lower left corner, a rectangular area at a lower right corner, or a central area on the photographing preview interface. Specifically, the first input may be an input of dragging the photographing identifier on the photographing preview interface by the user, or an input of sliding the user in a preset area on the photographing preview interface.
In practical application, when the mobile terminal displays the shooting preview interface, if an image with a larger view field needs to be shot, the user may drag the shooting identifier, or slide in a preset area on the shooting preview interface, so that the mobile terminal may receive a first input of the user on the shooting preview interface, and execute step 902 to adjust the shooting view field.
According to the embodiment of the invention, the shooting field of view is adjusted by receiving the first input of dragging the shooting identification on the shooting preview interface by the user or receiving the first input of sliding of the user in the preset area on the shooting preview interface, so that the operation is simple and convenient, and the shooting device is interesting.
And 902, responding to the first input, respectively moving the target assembly to at least two preset positions for shooting to obtain at least two images.
In the embodiment of the present invention, the at least two preset positions have a corresponding relationship with the operation track of the first input. Specifically, after receiving a first input of the user on the shooting preview interface, an operation track of the first input may be obtained, where the operation track of the first input may be a track formed from a start position point of the first input to an end position point of the first input, and optionally, the operation track of the first input may be a triangle, a rectangle, a circle, an ellipse, an arc, and the like.
In this step, the first input operation track may be matched with a preset dragging track, if the first input operation track is matched with the preset dragging track, the target assembly is moved to at least two preset positions to shoot, so as to obtain at least two images, otherwise, the process may be ended, or a conventional shooting process is executed, etc.; the first input operation track can also be matched with a preset dragging track to determine at least two preset positions corresponding to the first input operation track, so that the target assembly is moved to the at least two preset positions to be shot respectively to obtain at least two images; or moving the target assembly to a preset position corresponding to the position of each vertex of the first input operation track according to each vertex of the first input operation track, and shooting to obtain at least two images and the like.
It can be understood that, in response to the first input of the user on the shooting preview interface, the preview image after the shooting field of view is updated may be displayed on the shooting preview interface, that is, each time the target component moves to a preset position, the preview image corresponding to the preset position is displayed on the shooting preview interface, so that the user can view the preview image corresponding to each preset position in real time, or the preview image displayed when the first input is received may be maintained and displayed on the shooting preview interface until step 902 is completed, so as to avoid flickering of the image displayed on the shooting preview interface. Optionally, after the step 902 is finished, the target component of the mobile terminal may be controlled to return to the position where the target component was located before the adjustment of the shooting field of view.
Optionally, in the embodiment of the present invention, the lens or the image sensor may be driven to move to different positions by a motor in the OIS module of the mobile terminal camera, so that the cost may be saved. It is understood that the embodiment of the present invention may additionally provide a motor for driving the lens or the image sensor to move to a different position.
And step 903, outputting a target image obtained by synthesizing the at least two images.
In the embodiment of the invention, the second shooting view field of the target image is larger than the first shooting view field, namely the shooting view field of the synthesized image is larger than the first shooting view field before the shooting view field is adjusted.
In this step, the at least two images may be registered and fused to remove the overlapping portions of the at least two images, thereby obtaining the target image. It can be understood that the image registration algorithm may be an image registration algorithm based on gray information, an image registration algorithm based on a transform domain, or an image registration algorithm based on features, and the image fusion algorithm may be an image fusion algorithm based on wavelet transform, an image fusion algorithm based on pyramid change, an image fusion algorithm based on color space, and the like, which is not limited in the implementation of the present invention. Optionally, after the target image is obtained, the target image may be directly displayed on a shooting preview interface of the mobile terminal, and the target image may also be kept in an album of the mobile terminal for the user to view.
Specifically, because the at least two images are images shot when the target assembly is located at different preset positions, the target image obtained by combining the at least two images has a larger view field relative to the image shot when the target assembly is located at one position, so that a lens with a larger FOV (field of view) does not need to be replaced, the image sensor frame does not need to be increased, a user does not need to move the mobile terminal to shoot, the image with a larger view field can be obtained, the cost is lower, and the operation is more convenient.
In the embodiment of the present invention, the mobile terminal may be a mobile phone, a Tablet personal Computer (Tablet personal Computer), a Laptop Computer (Laptop Computer), a personal digital assistant (PDA for short), a Wearable Device (Wearable Device), or the like.
According to the photographing method, a first input of a user on a shooting preview interface is received in a state that a preview image of a first shooting view field is displayed on the shooting preview interface, wherein the first input is used for adjusting the shooting view field; responding to the first input, respectively moving the target assembly to at least two preset positions for shooting to obtain at least two images; outputting a target image obtained by synthesizing the at least two images; the at least two preset positions and the operation track of the first input have corresponding relation; the second shooting view field of the target image is larger than the first shooting view field, the image with the larger view field can be shot without a user moving the mobile terminal, the operation is convenient, obvious splicing traces are not prone to occurring, in addition, the target assembly is shot based on the first input movement of the user on the shooting preview interface, and convenience in operation and flexibility in shooting control can be enhanced.
Optionally, in step 902, that is, in response to the first input, moving the target assembly to at least two preset positions respectively for shooting to obtain at least two images, where the step includes:
under the condition that the first input operation track is matched with a first preset track, the target assembly is moved to at least two first preset positions respectively to be shot, and at least two images are obtained;
when the target assembly moves to the first preset position, the vertex of the image sensor intersects with a first target point on the image circle of the lens; the first target point is an intersection point of straight lines where the image circle of the lens and the diagonal line of the image sensor are located when the central point of the image circle of the lens and the central point of the image sensor are overlapped.
In the embodiment of the present invention, the first preset track may be set according to actual requirements, for example, the first preset track may include one or at least two of a triangle, a rectangle, a flag, and the like. Specifically, when the first input operation track is matched with the first preset track, the target assembly can be moved to at least two first preset positions to shoot, so as to obtain at least two images, when the first input operation track is not matched with the first preset track, the process can be ended, a conventional shooting process can be executed, or the first input operation track can be continuously matched with a second preset track, wherein the second preset track is different from the first preset track. The first preset position may be a position corresponding to an intersection of a vertex of the image sensor and a first target point on the image circle of the lens, that is, when the target assembly moves to the first preset position, the vertex of the image sensor and the first target point on the image circle of the lens intersect.
For ease of understanding, embodiments of the present invention are described below with reference to fig. 10 to 16:
referring to fig. 10, points a to D are respectively intersections of straight lines where diagonal lines of the image circle 40 and the image sensor 10 are located when a center point of the image circle 40 and a center point of the image sensor 10 (i.e., an image recording area) are overlapped (i.e., overlapped with the center point 0), and the first target point may include at least two points among the points a to D.
In practical applications, when the operation track of the first input (for example, the first operation track 1 shown in fig. 11, that is, the flag-shaped operation track abcd) matches the first preset track, the target assembly (for example, the lens or the image sensor) may be moved to at least two first preset positions for shooting, and when the target assembly is moved to the first preset positions, the vertex of the image sensor 10 intersects with the first target point (that is, the point from the point a to the point D) on the image circle 40, for example, referring to fig. 12 to 15, the four vertices of the image sensor 10 intersect with one of the points from the point a to the point D on the image circle 40.
It should be noted that, when the image sensor or the lens is moved by the OIS module, if the movable stroke of the OIS module is limited, so that the vertex of the image sensor and the first target point on the image circle of the lens cannot be intersected, the target assembly may be moved as much as possible, so that the vertex of the image sensor is close to the first target point in the image circle 40, so as to expand the shooting field of view.
Specifically, after four images captured when four vertices of the image sensor 10 intersect with one of the points a to D in the image circle 40, the four images may be combined to obtain the target image 50 shown in fig. 16, that is, a rectangular region formed by the points a to D.
According to the embodiment of the invention, when the target assembly moves to the first preset position, the vertex of the image sensor is intersected with the first target point on the image circle of the lens, and the first target point is the intersection point of the straight line where the image circle of the lens and the diagonal line of the image sensor are located when the central point of the image circle of the lens is superposed with the central point of the image sensor, so that the image which has the same length-width ratio as the original image but has a larger view field can be spliced.
Optionally, in step 902, that is, in response to the first input, moving the target assembly to at least two preset positions respectively for shooting to obtain at least two images, where the step includes:
under the condition that the first input operation track is matched with a second preset track, the target assembly is moved to at least two second preset positions respectively to be shot, and at least two images are obtained;
when the target assembly moves to the second preset position, the vertex of the image sensor intersects with a second target point on the image circle of the lens; the second target point is a point on a target circular arc on the image circle of the lens; the target arc is an arc between two adjacent intersection points in intersection points of straight lines where the image ring of the lens and the four sides of the image sensor are located when the central point of the image ring of the lens is coincident with the central point of the image sensor.
In the embodiment of the present invention, the second preset track may be reasonably set according to an actual situation, for example, the second preset track may include one or at least two of a circle, an ellipse, an arc, and the like. It can be understood that, in the case that the operation trajectory of the first input does not match the second preset trajectory, the flow may be ended, and the regular photographing operation may also be performed.
The second preset position may be a position corresponding to an intersection of a vertex of the image sensor and a second target point on the image circle of the lens, that is, when the target assembly moves to the second preset position, the vertex of the image sensor and the second target point on the image circle of the lens intersect, the second target point is a point on a target arc on the image circle of the lens, the target arc may include one arc on the image circle or at least two arcs on the image circle, and the second target point may include at least two points on the target arc.
For ease of understanding, embodiments of the present invention are described below with reference to fig. 17 to 19:
referring to fig. 17, points E to L are respectively intersections of straight lines where four sides of the image sensor 10 are located and the image ring 40 when the central point of the image sensor 10 (i.e., the image recording area) and the central point of the image ring 40 coincide with each other, and the target arc may include one or at least two of an arc LE (i.e., an arc between the points L and E), an arc FG (i.e., an arc between the points F and G), an arc HI (i.e., an arc between the points H and I) and an arc JK (i.e., an arc between the points J and K) on the image ring 40.
Taking the target arcs including the arc LE, the arc FG, the arc HI, and the arc JK as an example, the second target point may include at least two points on each of the arcs, and for example, the second target point may include two end points and a middle point on each of the arcs. It should be noted that the more points on the arc included by the second target point, the larger the field of view of the obtained stitched image.
In practical applications, when the first input operation track (for example, the second operation track 2 shown in fig. 18, that is, the operation track abcde) matches with the second preset track, the target assembly (for example, the lens or the image sensor) may be moved to at least two second preset positions for shooting, and when the target assembly is moved to the second preset positions, the vertex of the image sensor 10 intersects with the second target point (that is, the point on the circular arc) on the image circle 40. Alternatively, the target assemblies may be moved to the second preset positions respectively according to a preset moving sequence.
For example, the image sensor 10 may be moved in the arrow direction shown in fig. 17 with the point L on the arc LE as a starting point, that is, the vertex of the upper left corner of the image sensor 10 may be moved along the arc LE in the arrow direction corresponding to the arc LE, and one image may be taken each time the image sensor is moved; secondly, moving the vertex of the upper right corner of the image sensor 10 along the arc FG according to the arrow direction corresponding to the arc FG, and shooting one image every time the vertex moves; moving the lower right vertex of the image sensor 10 along the arc HI according to the arrow direction corresponding to the arc HI, and shooting one image every time the image sensor moves; finally, the lower left vertex of the image sensor 10 is moved along the arc JK in the direction of the arrow corresponding to the arc JK, and one image is taken every time the image sensor is moved.
Specifically, after obtaining the images captured when the four vertexes of the image sensor 10 respectively move along the corresponding arcs in the image circle 40, the captured images may be stitched, so that the target image 50 shown in fig. 19, that is, the area with the arc formed by the point E to the point L, may be obtained.
In the embodiment of the present invention, when the target assembly moves to the second preset position, the vertex of the image sensor intersects with a second target point on the image circle of the lens, the second target point is a point on a target arc on the image circle of the lens, and the target arc is an arc between two adjacent intersection points in intersection points of straight lines where the image circle of the lens and the four sides of the image sensor are located when the central point of the image circle of the lens coincides with the central point of the image sensor, so that the field of view of the combined image can be maximized.
Optionally, the embodiment of the present invention may combine the two implementation manners, that is, in a case that the first input operation trajectory is matched with a first preset trajectory, the target assembly is respectively moved to at least two first preset positions to perform shooting, so as to obtain at least two images; under the condition that the first input operation track is matched with the second preset track, the target assembly is moved to at least two second preset positions to be shot respectively to obtain at least two images, so that a user can select different implementation modes for expanding the shooting view field of the images by inputting different first input operation tracks, and convenience in operation and flexibility in shooting control are improved.
Optionally, in step 902, that is, moving the target assembly to at least two preset positions for shooting according to the first input operation trajectory, respectively, to obtain at least two images, where the step includes:
acquiring each vertex of the first input operation track;
and moving the target assembly to a preset position corresponding to the position of each vertex of the first input operation track respectively to shoot to obtain at least two images.
In the embodiment of the present invention, a corresponding relationship between the position of the vertex of the first input operation trajectory and the preset position may be established in advance. For example, a vertex at the upper left corner of the first input operation track corresponds to a preset position a, a vertex at the lower left corner of the first input operation track corresponds to a preset position B, a vertex at the upper right corner of the first input operation track corresponds to a preset position C, and a vertex at the lower right corner of the first input operation track corresponds to a preset position D, wherein the vertex at the upper left corner of the image sensor intersects with a point a on the image circle when the target assembly moves to the preset position a, the vertex at the lower left corner of the image sensor intersects with a point D on the image circle when the target assembly moves to the preset position B, the vertex at the upper right corner of the image sensor intersects with a point B on the image circle when the target assembly moves to the preset position C, and the lower right vertex of the image sensor intersects with a point C on the image circle when the target assembly moves to the preset position D.
Optionally, when the operation trajectory of the first input formed by the obtained drag input includes a vertex of a lower left corner and a vertex of a lower right corner (for example, the operation trajectory of the first input is an upright triangle with a start drag point of the photographing button as a vertex of the uppermost part), the target component may be moved to the preset position b and the preset position d respectively for photographing; when the operation track of the first input formed by the acquired dragging input comprises a vertex at the upper left corner and a vertex at the upper right corner (for example, the operation track of the first input is an inverted triangle with the initial dragging point of the photographing button as the lowest vertex), the target assembly can be moved to the preset position a and the preset position c respectively for photographing; when the operation trajectory of the first input formed by the acquired dragging input includes a vertex of an upper left corner, a vertex of an upper right corner, a vertex of a lower left corner, and a vertex of a lower right corner (for example, the operation trajectory of the first input is a rectangle), the target component may be moved to the preset position a, the preset position c, the preset position b, and the preset position d, respectively, for shooting. Therefore, the user can control the target component to move to different preset positions for shooting by inputting different operation tracks of the first input.
According to the embodiment of the invention, at least two images are obtained by acquiring each vertex in the first input operation track and respectively moving the target assembly to the preset position corresponding to the position of each vertex in the first input operation track to shoot, so that a user can control the target assembly to move to different preset positions to shoot by inputting different first input operation tracks, the flexibility of shooting control is improved, and the shooting requirements of the user on the images with different view field sizes can be met.
Optionally, the obtaining each vertex in the operation trajectory of the first input includes:
acquiring each vertex of the first input operation track and the operation sequence of each vertex;
correspondingly, the moving the target assembly to the preset position corresponding to the position of each vertex of the first input operation track respectively to shoot to obtain at least two images includes:
and moving the target assembly to a preset position corresponding to the position of each vertex of the first input operation track in sequence according to the operation sequence of each vertex, and shooting to obtain at least two images.
For example, if the operation sequence of the vertexes of the first input operation trajectory is the vertex of the lower left corner, the vertex of the upper right corner and the vertex of the lower right corner in turn, the target component can be moved to the preset position b, the preset position a, the preset position c and the preset position d in turn to perform shooting; if the operation sequence of the vertex of the first input operation track is the vertex of the lower right corner, the vertex of the lower left corner, the vertex of the upper left corner and the vertex of the upper right corner in sequence, the target assembly can be moved to the preset position d, the preset position b, the preset position a and the preset position c in sequence to shoot.
In the embodiment of the invention, the target component is moved to the preset position corresponding to the position of each vertex in the first input operation track for shooting according to the operation sequence of each vertex in the first input operation track, so that a user can flexibly control the movement of the target component through different dragging inputs, and the control mode of image shooting is enriched.
It should be noted that, in the embodiment of the present invention, the different implementation manners may be combined according to actual requirements, for example, when the operation trajectory of the first input matches a first preset trajectory, each vertex in the operation trajectory of the first input is obtained; respectively moving the target assembly to a first preset position corresponding to the position of each vertex in the first input operation track for shooting to obtain at least two images; under the condition that the first input operation track is matched with a second preset track, each vertex in the first input operation track is obtained; and moving the target assembly to a second preset position corresponding to the position of each vertex in the first input operation track respectively to shoot to obtain at least two images.
