[0036] It should be noted that the camera movement parameter adjustment method provided in the embodiments of the present application can be executed by electronic devices such as mobile phones, tablet computers, laptop computers, PDAs, and vehicle-mounted electronic devices. In some embodiments of the present application, the camera movement parameter adjustment method provided in the embodiments of the present application is described by taking the electronic device as the execution subject to execute the camera movement parameter adjustment method as an example.

[0037] The camera movement parameter adjustment method provided in the embodiment of the present application can be applied to the scene of shooting a stage.

[0038] Among them, one specific application scenario is that when a user is watching a concert of singer A, he or she takes a photo of the stage of the concert. The user hopes to achieve automatic camera movement and shooting of the stage by means of changes in light from the light sources on the stage. Another specific application scenario is that when a user is watching a concert of singer A, he or she takes a photo of the stage of the concert.

[0039] It should be noted that the above application scenario is only an example, and other application scenarios may also be included in actual application, for example, a user wishes to realize automatic camera movement shooting of the stage through light changes of light sources on the stage and character movements at the same time.

[0040] Figure 1 : is a flowchart of a method for adjusting camera movement parameters provided by some embodiments of the present application. The method for adjusting camera movement parameters may include:

[0041] Step 101: determining first camera movement parameter information of a camera according to first light information of an object light source in a first preview image, wherein the object light source is a light source corresponding to a tracked shooting object among at least two light sources in a shooting scene;

[0042] In some embodiments of the present application, when the camera application of the electronic device is started, the camera application runs, and the camera application in the running state detects objects in the preview image, detects multiple objects included in the preview image, and the user selects a photographic object that needs to be tracked from the multiple objects.

[0043] The embodiments of the present application do not limit the method used to detect the object, and any available method can be applied to the embodiments of the present application. For example, when performing light source detection, the preview image can be binarized to obtain a black-and-white binary image, in which the light source irradiation area is white and other areas are black; edge straight line detection is performed on the black-and-white binary image to detect the edge straight lines in the black-and-white binary image; the intersection of the detected edge straight lines and the area with the highest brightness in the image are the imaging position of the light source in the preview image. When performing person detection, the person detection algorithm in the related art can be used to detect the person in the image.

[0044] After selecting a photographic object to be tracked from multiple objects, a corresponding camera movement control direction can be set for the photographic object to be tracked. When the object to be tracked is a light source, at least one camera movement control direction can be set for the light source. When the object to be tracked is a non-light source object, each non-light source object can be set to correspond to only one camera movement control direction, and different non-light source objects correspond to different camera movement control directions. A maximum of three non-light source objects to be tracked can be selected. Of course, when the object to be tracked is a non-light source object, at least one camera movement control direction can be set for each light source like a light source object, and the non-light source objects to be tracked are not limited to three.

[0045] In a scenario where the user wishes to automatically move the camera to shoot the stage by changing the light of the light source on the stage, the user can select the light source to be tracked from the detected light sources. Figure 2 As shown, Figure 2 It is a schematic diagram of selecting a light source object provided in some embodiments of the present application.

[0046] exist Figure 2 middle, Figure 2 Six light sources are shown in FIG. 1 , which are light source A, light source B, light source C, light source D, light source E, and light source F. When the user clicks Figure 2 After a certain light source is selected, the light source is determined as the light source to be tracked. Assume that the light sources selected by the user from the six light sources are: light source A, light source C, light source D and light source F.

[0047] After selecting the light source to be tracked, set the camera control direction corresponding to the light source. Figure 3 As shown, Figure 3 is a schematic diagram of setting the camera movement control direction provided by some embodiments of the present application. Figure 3 In the embodiment, the lens movement control direction of light source A, light source C and light source D is set to the front-to-back lens movement direction, the lens movement control direction of light source C is set to the left-right lens movement direction, and the lens movement control direction of light source F is set to the up-down lens movement direction. That is, light source A, light source C and light source D are set to control the lens movement in the front-to-back lens movement direction together, light source C is set to control the lens movement in the left-right lens movement direction, and light source F is set to control the lens movement in the up-down lens movement direction.

[0048] In a scene where the user wishes to realize automatic camera movement of the stage through the movement of characters on the stage, the user can select the character to be tracked from the detected characters. Figure 4 As shown, Figure 4 Schematic diagram of selecting characters provided by some embodiments of the present application. Figure 4 middle, Figure 4 Six light sources and three characters are shown in the figure. The six light sources are light source A, light source B, light source C, light source D, light source E and light source F. The three characters are character I, character J and character K. When the user clicks Figure 4 After selecting a character in the tracking method, the character is determined as the character to be tracked. Assume that the characters selected by the user from the three characters are: character I and character J.

[0049] After selecting the person to be tracked, set the camera control direction corresponding to the person. Figure 5 As shown, Figure 5 FIG. 1 is another schematic diagram of setting the direction of the camera movement control provided by some embodiments of the present application. Figure 5 , the camera movement control direction of characters I and J is set to the front-to-back camera movement direction, the camera movement control direction of character I is set to the left-right camera movement direction, and the camera movement control direction of character J is set to the up-down camera movement direction.

[0050] In some possible implementations of the embodiments of the present application, the mirror movement control information may include the movement amount of the focus motor and the movement amount of the anti-shake motor. Accordingly, step 101 may include: determining the angle change amount corresponding to the object light source in the three mirror movement directions respectively according to the first light information and the second light information; wherein the second light information is the light information of the object light source in the second preview image, the second preview image is a preview image adjacent to the first preview image, the acquisition time of the second preview image is earlier than the acquisition time of the first preview image, and the three mirror movement directions include the front-to-back mirror movement direction, the left-to-right mirror movement direction, and the up-and-down mirror movement direction; according to the angle change amount, determining the average angle change amount in each mirror movement direction; according to the average angle change amount and the preset mirror movement range corresponding to each mirror movement direction, determining the movement amount of the focus motor and the movement amount of the anti-shake motor.

[0051] In an embodiment of the present application, the changes in the light source corresponding to the tracked object in the shooting scene can be converted into the movement of the focus motor and the anti-shake motor. The movement of the focus motor and the anti-shake motor is utilized to increase the dynamic effect of the captured video and create a dynamic atmosphere of the shooting scene.

[0052] In some possible implementations of the embodiments of the present application, determining the angular changes of the object light source in three mirror movement directions respectively according to the first light information and the second light information may include: establishing a rectangular coordinate system with the imaging position of the object light source in the first preview image as the origin, the horizontal direction as the X-axis, and the vertical direction as the Y-axis; determining a first difference between a first angle corresponding to the first light information and a second angle corresponding to the second light information as the angular change of the object light source in the front-back mirror movement direction; determining a second difference between a third angle and a fourth angle as the angular change of the object light source in the left-right mirror movement direction; wherein the third angle is the angle between the bisector of the first angle and the X-axis, and the fourth angle is the angle between the bisector of the second angle and the X-axis; determining a third difference between the fifth angle and the sixth angle as the angular change of the object light source in the up-down mirror movement direction; wherein the fifth angle is the angle between the bisector of the first angle and the Y-axis, and the sixth angle is the angle between the bisector of the second angle and the Y-axis.

[0053] For example, Figure 6 As shown, Figure 6 It is a schematic diagram of light provided by some embodiments of the present application.

[0054] In a scenario where the user wishes to automatically move the camera to shoot the stage by changing the light source on the stage, Figure 6In the example, r11 and r12 are two boundaries of the imaging range of the illumination range of the tracked light source in the first preview image; r21 and r22 are two boundaries of the imaging range of the illumination range of the tracked light source in the second preview image. Figure 6 In the figure, r11 and r12 are two boundaries of the imaging range of the illumination range of the light source illuminating the tracked person in the first preview image; r21 and r22 are two boundaries of the imaging range of the illumination range of the light source illuminating the tracked person in the second preview image.

[0055] r10 is the bisector of the angle between r11 and r12; r20 is the bisector of the angle between r21 and r22. Assume that the angle between r11 and r12 is 30°, the angle between r21 and r22 is 25°, the angle between r10 and the X-axis is 30°, the angle between r20 and the X-axis is 45°, the angle between r10 and the Y-axis is 60°, and the angle between r20 and the X-axis is 45°.

[0056] Then the angle change of the light source in the front-to-back mirror movement direction is 5°; the angle change of the light source in the left-right mirror movement direction is -15°; and the angle change of the light source in the up-and-down mirror movement direction is 15°.

[0057] In some possible implementations of the embodiments of the present application, the object light source includes N light sources, where N is an integer greater than 1; determining the average value of the angle change in each mirror movement direction based on the angle change may include: when the tracked shooting object is the object light source, calculating the sum of the angle changes of the first reference light source in the front-to-back mirror movement direction to obtain a first sum value; determining the ratio of the first sum value to the number of first reference light sources as the average value of the angle change in the front-to-back mirror movement direction; wherein the first reference light source is a light source corresponding to the front-to-back mirror movement direction among the N light sources; calculating the sum of the angle changes of the second reference light source in the left-to-right mirror movement direction to obtain a second sum value; determining the ratio of the second sum value to the number of second reference light sources as the average value of the angle change in the left-to-right mirror movement direction; wherein the second reference light source is a light source corresponding to the left-to-right mirror movement direction among the N light sources; calculating the sum of the angle changes of the third reference light source in the up-down mirror movement direction to obtain a third sum value; determining the ratio of the third sum value to the number of third reference light sources as the average value of the angle change in the up-down mirror movement direction; wherein the third reference light source is a light source corresponding to the up-down mirror movement direction among the N light sources.

[0058] In some possible implementations of the embodiments of the present application, in a scenario where a user wishes to achieve automatic camera movement shooting of a stage by means of light changes of a light source on the stage, when the tracked shooting object is an object light source, the average value of the angle change in each camera movement direction can be calculated according to the following formula (1).

[0059]

[0060] In formula (1), ΔAF1 is the average value of the angle change in the forward and backward mirror movement direction, N AF1 is the number of all light sources in the forward and backward mirror movement direction, ΔZ i ΔOIS is the angle change of the i-th light source in the front-to-back mirror direction when the mirror control direction is the front-to-back mirror direction; x1 is the average value of the angle change in the left and right mirror directions, N oisx1 is the number of all light sources whose mirror control direction is the left or right mirror direction, ΔX i ΔOIS is the angle change of the i-th light source in the left and right mirror movement direction when the mirror movement control direction is the left and right mirror movement direction; y1 is the average value of the angle change in the up and down mirror movement direction, N oisy1 is the number of all light sources whose mirror control direction is up and down, ΔY i is the angle change of the i-th light source in the up-down mirror movement direction whose mirror movement control direction is the up-down mirror movement direction.

[0061] For example, in combination with the above Figure 3 The tracked light sources include light source A, light source C, light source D and light source F; the mirror movement control directions of light source A, light source C and light source D are set to be the front-to-back mirror movement direction, the mirror movement control direction of light source C is the left-right mirror movement direction, and the mirror movement control direction of light source F is the up-down mirror movement direction.

[0062] The angle changes of light source A in the front-to-back, left-to-right, and up-and-down directions are 6°, -15°, and 15°, respectively; the angle changes of light source C in the front-to-back, left-to-right, and up-and-down directions are 10°, 30°, and -30°, respectively; the angle changes of light source D in the front-to-back, left-to-right, and up-and-down directions are -10°, -20°, and 20°, respectively; the angle changes of light source F in the front-to-back, left-to-right, and up-and-down directions are 8°, 16°, and -16°, respectively.

[0063] Then the average value of the angle change in the front-back mirror movement direction is: (6°+10°-10°) / 3, that is, 2°. The average value of the angle change in the left-right mirror movement direction is: 30° / 1, that is, 30°. It can be understood that since only light source C is controlling the mirror movement in the left-right mirror movement direction, at this time, the average value of the angle change in the left-right mirror movement direction is the angle change of light source C in the left-right mirror movement direction. The average value of the angle change in the up-down mirror movement direction is: -16° / 1, that is, -16°. It can be understood that since only light source F is controlling the mirror movement in the up-down mirror movement direction, at this time, the average value of the angle change in the up-down mirror movement direction is the angle change of light source F in the up-down mirror movement direction.

[0064] In some possible implementations of the embodiments of the present application, determining an average value of the angle change in each mirror movement direction based on the angle change may include: when the tracked photographic object is a non-light source object, calculating the sum of the angle changes of the fourth reference light source in the front and back mirror movement directions to obtain a fourth sum value; determining the ratio of the fourth sum value to the number of fourth reference light sources as the average value of the angle changes in the front and back mirror movement directions; wherein the fourth reference light source is a light source among the object light sources that illuminates the photographic object; calculating the sum of the angle changes of the fourth reference light source in the left and right mirror movement directions to obtain a fifth sum value; determining the ratio of the fifth sum value to the number of fourth reference light sources as the average value of the angle changes in the left and right mirror movement directions; calculating the sum of the angle changes of the fourth reference light source in the up and down mirror movement directions to obtain a sixth sum value; and determining the ratio of the sixth sum value to the number of fourth reference light sources as the average value of the angle changes in the up and down mirror movement directions.

[0065] In some possible implementations of the embodiments of the present application, in a scenario where a user wishes to automatically move the camera to shoot the stage through the movement of characters on the stage, when the tracked subject is a person, the average value of the angle change in each camera direction can be calculated according to the following formula (2).

[0066]

[0067] In formula (2), ΔAF2 is the average value of the angle change in the front and rear mirror movement directions, N AF2 is the number of light sources corresponding to all characters in the forward and backward camera movement direction, ΔZ j ΔOIS is the angle change of the jth light source in the forward and backward direction among all the light sources corresponding to the characters in the forward and backward direction; x2 is the average value of the angle change in the left and right mirror directions, N oisx2 is the number of light sources corresponding to all characters whose camera movement direction is left or right, ΔX jΔOIS is the angle change of the jth light source in the left and right direction of the camera among all the light sources corresponding to the characters in the left and right direction of the camera; y2 is the average value of the angle change in the up and down mirror movement direction, N oisy2 ΔY is the number of light sources corresponding to all characters in the up and down camera movement direction. j It is the angle change of the jth light source in the up-down direction among the light sources corresponding to all characters whose camera control direction is the up-down direction.

[0068] For example, in combination with the above Figure 5 , the tracked characters include character I and character J; the camera movement control directions of character I and character J are set to be the front-to-back camera movement direction, the camera movement control direction of character I is the left-right camera movement direction, and the camera movement control direction of character J is the up-down camera movement direction. When character I and character J are set as tracked characters, the light sources irradiating character I are light source A, light source C, light source D, and light source F, and the light source irradiating character J is light source B.

[0069] When calculating the average value of the angle change in each direction of movement, the angle changes of light source A in the front-to-back direction, left-to-right direction, and up-down direction are 6°, -15°, and 15°, respectively; the angle changes of light source B in the front-to-back direction, left-to-right direction, and up-down direction are 10°, 30°, and -30°, respectively; the angle changes of light source C in the front-to-back direction, left-to-right direction, and up-down direction are 10°, 30°, and -30°, respectively; the angle changes of light source D in the front-to-back direction, left-to-right direction, and up-down direction are -10°, -20°, and 20°, respectively; the angle changes of light source F in the front-to-back direction, left-to-right direction, and up-down direction are 14°, 16°, and -16°, respectively.

[0070] The average value of the angle change in the forward and backward movement direction is: (6°+10°+10°-10°+14°) / 5, that is, 6°; the average value of the angle change in the left and right movement direction is: (6°+10°-10°+14°) / 5, that is, 6°; the average value of the angle change in the up and down movement direction is: (-30°) / 1, that is, -30°.

[0071] In some possible implementations of the embodiments of the present application, it is possible to select certain light sources and certain people as objects to be tracked. In this case, the average value of the angle change in each camera movement direction corresponding to the light source can be calculated according to the above formula (1), and the average value of the angle change in each camera movement direction corresponding to the person can be calculated according to the above formula (2), and then the two values ​​are averaged to obtain the final average value of the angle change in each camera movement direction.

[0072] In some possible implementations of the embodiments of the present application, determining the movement amount of the focus motor and the movement amount of the anti-shake motor according to the average value of the angle change and the preset mirror movement range corresponding to each mirror movement direction may include: calculating a fourth difference between the maximum value and the minimum value of the mirror movement range corresponding to the front and rear mirror movement directions; determining the movement amount of the focus motor according to the fourth difference and the average value of the angle change in the front and rear mirror movement directions; calculating a fifth difference between the maximum value and the minimum value of the mirror movement range corresponding to the left and right mirror movement directions; determining the lateral movement amount of the anti-shake motor according to the fifth difference and the average value of the angle change in the left and right mirror movement directions; calculating the sixth difference between the maximum value and the minimum value of the mirror movement range corresponding to the upper and lower mirror movement directions; and determining the longitudinal movement amount of the anti-shake motor according to the sixth difference and the average value of the angle change in the upper and lower mirror movement directions.

[0073] In some possible implementations of the embodiments of the present application, the camera movement range corresponding to each camera movement direction may be pre-set.

[0074] For example, Figure 7 As shown, Figure 7 Schematic diagram of setting the camera movement range provided in some embodiments of the present application. Figure 7 In the , the forward and backward movement direction corresponds to the movement range of Z1 to Z2, the left and right movement direction corresponds to the movement range of X1 to X2, and the up and down movement direction corresponds to the movement range of Y1 to Y2.

[0075] In some possible implementations of the embodiments of the present application, the movement amount of the focus motor, the lateral movement amount of the anti-shake motor, and the longitudinal movement amount of the anti-shake motor can be determined according to the following formula (3).

[0076]

[0077] In formula (3), AF code is the movement amount of the focus motor, ΔAF is the average value of the angle change in the front and back mirror movement direction, Z2 is the maximum value of the mirror movement range corresponding to the front and back mirror movement direction, and Z1 is the minimum value of the mirror movement range corresponding to the front and back mirror movement direction; OISx code is the lateral movement of the anti-shake motor, ΔOISx is the average value of the angle change in the left and right mirror movement directions, X2 is the maximum value of the mirror movement range corresponding to the left and right mirror movement directions, and X1 is the minimum value of the mirror movement range corresponding to the left and right mirror movement directions; OISy codeis the longitudinal movement of the anti-shake motor, ΔOISy is the average value of the angle change in the up and down mirror movement direction, Y2 is the maximum value of the mirror movement range corresponding to the up and down mirror movement direction, and Y1 is the minimum value of the mirror movement range corresponding to the up and down mirror movement direction; a, b, c, d, e and f are the conversion parameters for converting the average angle change to the movement amount, and a, b, c, d, e and f can be set according to actual needs. Optionally, the values ​​of a, c and e can be 180, the value of b can be 512, and the values ​​of d and f can be 1000.

[0078] For example, the average value of the angle change in the front-to-back direction is 9°, the average value of the angle change in the left-to-right direction is -27°, and the average value of the angle change in the up-down direction is 36°. The values ​​of a, c, and e are all 180, the value of b is 512, the values ​​of d and f are 1000, and Z2, Z1, X2, X1, Y2, and Y1 are 10, 5, 10, 5, 10, 5, respectively.

[0079] The movement of the focus motor AF code The lateral movement of the image stabilization motor is 128 steps (Code). code -750Code, the longitudinal movement of the anti-shake motor OISy code It is 1000Code.

[0080] In practical applications, after the movement amount of the motor in steps is determined, the movement amount of the motor in steps can be converted into the movement distance of the motor in micrometers according to the linearity of the motor.

[0081] For example, assuming that the linearity of the motor is 5000 steps / micron, after unit conversion, it can be concluded that the moving distance of the focus motor is 0.0256 microns, the lateral moving distance of the anti-shake motor is -0.15 microns, and the longitudinal moving distance of the anti-shake motor is 0.2 microns.

[0082] Step 102: Control the camera to move the camera according to the first camera movement control information.

[0083] After the movement amount of the focus motor, the lateral movement amount of the anti-shake motor and the longitudinal movement amount of the anti-shake motor are calculated by the above formula (3), the focus motor and the anti-shake motor can be controlled to move the corresponding movement amount to realize automatic mirror movement.

[0084] In some possible implementations of the embodiments of the present application, when the movement amount of the focus motor AF code When it is positive, the focus motor moves forward. When the movement amount of the focus motor is AF code When it is negative, the focus motor moves backward; when the lateral movement of the image stabilization motor OISx codeWhen it is positive, the image stabilization motor moves to the left. When the lateral movement of the image stabilization motor is OISx code When it is negative, the image stabilization motor moves to the right; when the longitudinal movement of the image stabilization motor OISy code When the vertical movement of the anti-shake motor is OISy, the anti-shake motor moves upward. code When negative, the image stabilization motor moves downward.

[0085] For example, the movement amount of the focus motor AF code The lateral movement of the image stabilization motor is 128 steps. code -750 steps, the longitudinal movement of the image stabilization motor OISy code The focus motor is controlled to move forward 128 steps, that is, to move forward 0.0256 microns, the anti-shake motor is controlled to move right 750 steps, that is, to move right 0.15 microns, and upward 1000 steps, that is, to move upward 0.2 microns.

[0086] It should be noted that the movement amount of the focus motor, the lateral movement amount of the anti-shake motor, and the longitudinal movement amount of the anti-shake motor calculated in the embodiment of the present application are only an example of the present application.

[0087] In an embodiment of the present application, the first camera movement parameter information is determined based on the first light information of the object light source in the first preview image, wherein the object light source is the light source corresponding to the tracked shooting object among at least two light sources in the shooting scene; and the camera movement parameters are adjusted based on the first camera movement parameter information. In this way, the camera movement parameters can be automatically adjusted based on the light source in the shooting scene, so that the user can use the electronic device to capture the image of interest in the stage scene in time, without missing any exciting and dynamic moments. By automatically adjusting the camera movement parameters, the dynamic effect of the video captured is increased, creating a dynamic atmosphere of the shooting scene.

[0088] It should be noted that after a certain light source is selected as the light source to be tracked, if the light source disappears from the first preview image, that is, the light source cannot be detected from the first preview image and the light information of the light source in the first preview image cannot be obtained, then in the process of determining the movement amount of the focus motor, the lateral movement amount of the anti-shake motor and the longitudinal movement amount of the anti-shake motor, the light source is ignored.

[0089] Exemplarily, in a scene where a user hopes to achieve automatic camera movement shooting of the stage by changing the light of the light sources on the stage, the tracked light sources include light source A, light source C, light source D and light source F. The camera movement control directions of light sources A, C and D are set to be front-to-back camera movement directions, the camera movement control direction of light source C is set to be left-to-right camera movement directions, and the camera movement control direction of light source F is set to be up-and-down camera movement directions.

[0090] When the light source C disappears, the average value of the angle change in the front-to-back direction is: the ratio of the sum of the angle change of the light source A in the front-to-back direction and the angle change of the light source D in the front-to-back direction to 2; the average value of the angle change in the left-right direction is 0, and no camera movement control is performed in the left-right direction; the average value of the angle change in the up-down direction is the angle change of the light source F in the up-down direction.

[0091] As another example, in a scene where a user wishes to achieve automatic camera movement of a stage through the movement of characters on the stage, after a certain character is selected as the object to be tracked, if the character disappears from the first preview image, that is, the character cannot be detected from the first preview image, then in the process of determining the movement amount of the focus motor, the lateral movement amount of the anti-shake motor, and the longitudinal movement amount of the anti-shake motor, the character is ignored.

[0092] For example, in combination with the above Figure 5 , the tracked persons are person I and person J. When the tracked persons are set to be person I and person J, the light sources irradiating person I are light source A, light source C, light source D and light source F, and the light source irradiating person J is light source B. The camera movement control directions of person I and person J are set to be the front-to-back camera movement direction, the camera movement control direction of person I is the left-to-right camera movement direction, and the camera movement control direction of person J is the up-down camera movement direction.

[0093] When character J disappears, the average value of the angle change in the front-to-back direction is: the ratio of the angle change of light source A, light source C, light source D, and light source F in the front-to-back direction to 4. Assuming that the angle changes of light source A, light source C, light source D, and light source F in the front-to-back direction are 5°, 6°, 2°, and 7°, respectively, then when character J disappears, the average value of the angle change in the front-to-back direction is (5°+6°+2°+7°) / 4, that is, 5°.

[0094] When character J disappears, the average value of the angle change in the left and right camera direction is: the ratio of the angle change of light source A, light source C, light source D and light source F in the left and right camera direction to 4. Assuming that the angle changes of light source A, light source C, light source D and light source F in the left and right camera direction are 3°, 3°, 2° and 0° respectively, then when character J disappears, the average value of the angle change in the front and back camera direction is (3°+3°+2°+0°) / 4, that is, 2°.

[0095] When character J disappears, since the camera movement control direction of character J is the up-down camera movement direction, character I does not perform camera movement control in the up-down camera movement direction. When character J disappears, no camera movement control is performed in the up-down camera movement direction.

[0096] As another example, in a scene where the user hopes to achieve automatic camera movement of the stage through the movement of characters on the stage, after a certain character is selected as the object to be tracked, if a light source illuminating the character disappears from the first preview image, that is, the light source cannot be detected from the first preview image, then in the process of determining the movement amount of the focus motor, the lateral movement amount of the anti-shake motor, and the longitudinal movement amount of the anti-shake motor, the light source is ignored.

[0097] For example, in combination with the above Figure 5 , the tracked persons are person I and person J. When the tracked persons are set to be person I and person J, the light sources irradiating person I are light source A, light source C, light source D and light source F, and the light source irradiating person J is light source B. The camera movement control directions of person I and person J are set to be the front-to-back camera movement direction, the camera movement control direction of person I is the left-to-right camera movement direction, and the camera movement control direction of person J is the up-down camera movement direction.

[0098] When light source A has not disappeared, the average value of the angle change in the front-to-back direction is: the ratio of the sum of the angle change of light source A in the front-to-back direction, the angle change of light source C in the front-to-back direction, the angle change of light source D in the front-to-back direction, the angle change of light source F in the front-to-back direction and the angle change of light source B in the front-to-back direction to 5; when light source A disappears, the average value of the angle change in the front-to-back direction is: the ratio of the sum of the angle change of light source C in the front-to-back direction, the angle change of light source D in the front-to-back direction, the angle change of light source F in the front-to-back direction and the angle change of light source B in the front-to-back direction to 4.

[0099] When light source A has not disappeared, the average value of the angle change in the left and right mirror movement direction is: the ratio of the sum of the angle change of light source A in the front and back mirror movement direction, the angle change of light source C in the front and back mirror movement direction, the angle change of light source D in the front and back mirror movement direction and the angle change of light source F in the front and back mirror movement direction to 4; when light source A disappears, the average value of the angle change in the left and right mirror movement direction is: the ratio of the sum of the angle change of light source C in the front and back mirror movement direction, the angle change of light source D in the front and back mirror movement direction and the angle change of light source F in the front and back mirror movement direction to 3.

[0100] When light source A is not gone, the average value of the angle change in the up-down direction is: the angle change of light source B; when light source A disappears, the average value of the angle change in the up-down direction is: the angle change of light source B. Since light source A is not the light source illuminating person J, it will not affect the control of the up-down direction.

[0101] Exemplarily, when light source A, light source C, light source D, light source F and light source B are all present, the angle changes of light source A in the front-to-back direction, left-to-right direction and up-and-down direction are 6°, -15° and 15° respectively; the angle changes of light source C in the front-to-back direction, left-to-right direction and up-and-down direction are 10°, 30° and -30° respectively; the angle changes of light source D in the front-to-back direction, left-to-right direction and up-and-down direction are -10°, -20° and 20° respectively; the angle changes of light source F in the front-to-back direction, left-to-right direction and up-and-down direction are 14°, 16° and -16° respectively, and the angle changes of light source B in the front-to-back direction, left-to-right direction and up-and-down direction are 5°, 17° and -17° respectively.

[0102] The average value of the angle change in the forward and backward movement direction is: (6°+10°-10°+14°+5°) / 5, that is, 5°; the average value of the angle change in the left and right movement direction is: (-15°+30°-20°+17°) / 4, that is, 3°; the average value of the angle change in the up and down movement direction is: (-17°) / 1, that is, -17°.

[0103] When light source C, light source D, light source F and light source B are not disappeared, but light source A disappears, the angle changes of light source C in the front-to-back direction, left-to-right direction and up-down direction are 10°, 30° and -30° respectively; the angle changes of light source D in the front-to-back direction, left-to-right direction and up-down direction are -10°, -20° and 20° respectively; the angle changes of light source F in the front-to-back direction, left-to-right direction and up-down direction are 14°, 16° and -16° respectively; the angle changes of light source B in the front-to-back direction, left-to-right direction and up-down direction are 5°, 17° and -17° respectively.

[0104] The average value of the angle change in the forward and backward movement direction is: (10°-10°+14°+5°) / 4, that is, 4.75°; the average value of the angle change in the left and right movement direction is: (30°-20°+17°) / 3, that is, 9°; the average value of the angle change in the up and down movement direction is: (-17°) / 1, that is, -17°.

[0105] In some possible implementations of the embodiments of the present application, after step 102, the camera movement control method provided by the embodiments of the present application may further include: when a new object in the shooting scene is detected through the first preview image, displaying prompt information; wherein the prompt information is used to determine whether to determine the new object as the tracked shooting object; when the second object is determined as the tracked shooting object, determining second camera movement parameter information of the camera according to third light information of the object light source in the third preview image, wherein the object light source includes the light source corresponding to the new object in the shooting scene; and adjusting the camera movement parameters according to the second camera movement parameter information.

[0106] In some possible implementations of the embodiments of the present application, there is a situation where a new object appears in the shooting scene, for example, a new light source is started or a new person appears. At this time, when the newly added object is detected in the shooting scene, a prompt message can be displayed to prompt whether to determine the newly added object as the tracked shooting object. If the user determines the newly added object as the tracked shooting object, the camera movement control direction of the newly added object can be set, and then, according to the third light information of the object light source in the third preview image, the second camera movement parameter information of the camera is determined; according to the second camera movement parameter information, the camera movement parameters are adjusted.

[0107] For example, it is assumed that during the shooting process, light source A and light source B are set as the tracked objects, and the camera's camera movement parameters are adjusted according to the light information of light source A and light source B. When a new object C is detected in the preview image, the user sets light source C as the tracked object as well. Then, the camera's camera movement parameters are adjusted according to the light information of light sources A, B and C.

[0108] For example, in a scene where a user wants to realize automatic camera movement of a stage by changing the light of a light source on the stage, when a new light source appears on the stage, the following is displayed: Figure 8 The interface shown, Figure 8 is a schematic diagram of the appearance of a newly added light source provided in some embodiments of the present application.

Fig.10 The new character that appears in the image is character L. When the user sets character L as the tracked character, it is displayed Fig.11 The interface shown, Fig.11 Schematic diagram of setting the camera movement control direction of a newly added character provided in an embodiment of the present application. Fig.11 The user can set the camera control direction of character L.

[0110] In an embodiment of the present application, during the shooting process, when a new object appears in the shooting scene, the tracked shooting object can be updated in time, and then the camera movement parameters can be adjusted based on the light source corresponding to the updated shooting object, thereby meeting the user's shooting needs.
