[0002] Many motorcyclists and bicycle riders place dashcams on their helmets to record images while riding. This not only allows them to record video evidence when a traffic accident occurs, but also allows them to record the travel process from the rider's perspective when riding. However, if the dashcam is placed on the helmet, the recorded images will tilt and shake with the rider's head movements, resulting in poor viewing experience or not showing the environment directly in front of the rider.

[0021] See also Figure 1 and Figure 2 One embodiment of the photographing device 1 of the present invention is suitable for being arranged on a helmet (not shown) to record the riding process of a user on a motorcycle or a bicycle.

[0022] The photographing device 1 includes a housing 11, a cover 12, a motion sensing unit 13, a first rotating unit 14, a second rotating unit 15, a photographing lens unit 16, and a processing unit 17 electrically connected to the motion sensing unit 13, the first rotating unit 14, the second rotating unit 15 and the photographing lens unit 16.

[0023] like Figure 1As shown, the housing 11 defines a virtual axis passing through the housing 11 itself, and the virtual axis is, for example, used as a first virtual axis L1 in this embodiment, and the extension direction of the first virtual axis L1 is, for example, used as a front-to-back extension direction D1 relative to the camera 1 in the six degrees of freedom of the three-dimensional space. In more detail, in this embodiment, the housing 11 is generally hollow cylindrical and extends along the first virtual axis L1 (that is, extends along the front-to-back extension direction D1), and the housing 11, for example, defines an installation space 110 capable of accommodating the activity sensing unit 13 and the processing unit 17. In addition, since the housing 11 is cylindrical in this embodiment, the cross-sectional shape of the installation space 110 is, for example, circular in this embodiment, but is not limited thereto.

[0024] The cover 12 can be combined with the shell 11 in the front-to-back extension direction D1, and the cover 12 includes an end wall 121 and a peripheral wall 122 extending from the periphery of the end wall 121 in a direction perpendicular to the end wall 121. In the present embodiment, both the end wall 121 and the peripheral wall 122 are transparent. However, in a similar implementation, the peripheral wall 122 may also be transparent in only one annular portion adjacent to the periphery of the end wall 121, and is not limited to the present embodiment. It is additionally noted that the cover 12 and the shell 11 can be fixedly combined with each other by existing combination methods such as tenons and threads. Since the combination method is not the focus of this patent specification, it will not be described in excessive detail.

[0025] The activity sensing unit 13 includes, for example, a gyroscope (not shown), and the gyroscope may be implemented as, for example, a micro-electromechanical system (MEMS) gyroscope, a laser gyroscope, or a fiber optic gyroscope. In addition, the activity sensing unit 13 is fixedly disposed on the housing 11 and, for example, is located in the installation space 110, whereby the activity sensing unit 13 can be used to sense the activity direction and activity amount of the housing 11 in six degrees of freedom.

[0026] The first rotating unit 14 is connected to the housing 11 and can be rotated in a rolling rotation direction R1 relative to the housing 11 relative to the front-rear extension direction D1 under the control of the processing unit 17. In more detail, in this embodiment, the first rotating unit 14 includes, for example, a cylindrical portion 141, a connecting portion 142 and a pivot shaft 143.

[0027] In the present embodiment, the shape of the cylindrical portion 141 matches the cross-sectional shape of the installation space 110, and is rotatably connected to the shell 11. More specifically, the cylindrical portion 141 protrudes from the installation space 110 along the first virtual axis L1 outside the installation space 110, and can be rotated around the first virtual axis L1 as the axis under the control of the processing unit 17 (that is, rotates along the rolling rotation direction R1). In other words, a portion of the cylindrical portion 141 is located within the installation space 110, and the cylindrical portion 141 is rotatably connected to the shell 11 by means of the portion located within the installation space 110. In addition, one end of the cylindrical portion 141 protruding outside the installation space 110 also defines a circular opening 140. Further, referring to Figure 3 In a preferred embodiment, the cylindrical portion 141 has an outer circumferential surface 144, and the shell 11 has an inner circumferential surface 111, and the portion of the outer circumferential surface 144 of the cylindrical portion 141 located in the installation space 110 is, for example, spaced apart from the inner circumferential surface 111 of the shell 11. In this way, when the cylindrical portion 141 rotates along the tumbling rotation direction R1, the portion of the outer circumferential surface 144 of the cylindrical portion 141 located in the installation space 110 will not rub against the inner circumferential surface 111 of the shell 11 to generate resistance, which helps to make the first rotating unit 14 as a whole rotate more smoothly.

[0028] The connecting portion 142 is connected to the cylindrical portion 141, and protrudes from the opening 140 along the first virtual axis L1 to the outside of the opening 140. More specifically, one end of the connecting portion 142 is located in the opening 140, and the connecting portion 142 is fixedly connected to the cylindrical portion 141 through the one end located in the opening 140, so that when the cylindrical portion 141 rotates along the tumbling rotation direction R1, the connecting portion 142 will be driven by the cylindrical portion 141 and rotate along the tumbling rotation direction R1 with the cylindrical portion 141.

[0029] The pivot axis 143 passes through the connecting portion 142 and the second rotating unit 15, and defines another virtual axis passing through the pivot axis 143. The other virtual axis is, for example, used as a second virtual axis L2 in this embodiment, and the second virtual axis L2 is, for example, perpendicularly intersecting with the first virtual axis L1, and the extension direction of the second virtual axis L2 is, for example, used as a left-right extension direction D2 relative to the front-back extension direction D1 in the six degrees of freedom of the three-dimensional space. In other words, the pivot axis 143 extends along the second virtual axis L2, that is, along the left-right extension direction D2.

[0030] The second rotating unit 15 has a front surface 151, and the second rotating unit 15 is pivotally connected to the connecting portion 142 of the first rotating unit 14 by the penetration of the pivot shaft 143. That is, the second rotating unit 15 is indirectly connected to the housing 11 through the first rotating unit 14 by being pivotally connected to the first rotating unit 14, and the second rotating unit 15 can be driven by the first rotating unit 14. Therefore, when the first rotating unit 14 rotates along the rolling rotation direction R1, the second rotating unit 15 will rotate along the rolling rotation direction R1 along with the first rotating unit 14. Further, the second rotating unit 15 can also be controlled by the processing unit 17 to rotate relative to the first rotating unit 14 with the pivot shaft 143 as the axis (equivalent to the second virtual axis L2 as the axis), which is equivalent to rotating relative to the housing 11 in a pitch rotation direction R2 relative to the front-rear extension direction D1.

[0031] The camera unit 16 is used to record images in a video recording manner under the control of the processing unit 17. Moreover, the camera unit 16 is disposed on the front surface 151 of the second rotating unit 15, so that the camera unit 16 can be driven by the second rotating unit 15 to rotate along with the second rotating unit 15 in the pitch rotation direction R2. Moreover, since the second rotating unit 15 can be driven by the first rotating unit 14, the camera unit 16 can also rotate along with the first rotating unit 14 in the roll rotation direction R1.

[0032] The processing unit 17 is, for example, implemented as a control circuit board having a central processing unit, and the processing unit 17 is, for example, disposed in the housing 11 and located in the installation space 110 , but is not limited thereto.

[0033] The processing unit 17 is used to obtain standard posture data related to the posture of the housing 11 in the real environment, and the standard posture data, for example, includes a standard roll angle corresponding to the roll rotation direction R1, and a standard pitch angle corresponding to the pitch rotation direction R2. In this embodiment, the standard roll angle and the standard pitch angle can be, for example, each implemented as an angle range (e.g., "-5 degrees to +5 degrees"), however, in other embodiments, the standard roll angle and the standard pitch angle can also be, for example, each implemented as a specific angle value (e.g., "0 degrees"), and are not limited to this embodiment.

[0034] In a first implementation of the present embodiment, the processing unit 17 obtains the standard posture data by, for example, controlling the camera unit 16 to perform video recording and shooting, controlling the activity sensing unit 13 to perform activity sensing, and transmitting a real-time shooting result generated by the camera unit 16 recording to the user device, so that the user device can display the real-time shooting result in real time, wherein the user device can be, for example, a smart phone or a tablet computer, thereby the user can watch the real-time shooting result on the user device. Then, when the processing unit 17 receives a setting instruction in the process of continuously transmitting the real-time shooting result to the user device, the processing unit 17 determines the standard roll angle and the standard pitch angle according to the current sensing result of the activity sensing unit 13 (for example, including a roll angle value and a pitch angle value), thereby generating the standard posture data including the standard roll angle and the standard pitch angle, wherein the setting instruction can, for example, come from the user device and is generated by the user device according to the user's operation. In other words, if the time point at which the processing unit 17 receives the setting instruction is taken as a designated time point, in a preferred embodiment, the processing unit 17 generates the standard posture data according to the sensing result generated by the activity sensing unit 13 at the designated time point. In this way, in addition to being able to view the real-time shooting result on the user device, the user can also operate the user device to output the setting instruction to the processing unit 17 when the user feels that the current shooting angle of the real-time shooting result is suitable and the viewing experience is good, so that the processing unit 17 sets the standard posture data according to the current sensing result of the activity sensing unit 13.

[0035] In a second implementation of the present embodiment, the processing unit 17 obtains the standard posture data by, for example, controlling the camera unit 16 to perform video recording and the activity sensing unit 13 to perform activity sensing during a test shooting period under the operation of the user, so as to obtain a test shooting result generated by the camera unit 16 during the test shooting period and an activity sensing record generated by the activity sensing unit 13 during the test shooting period after the test shooting period ends, wherein the activity sensing record, for example, includes a plurality of historical activity sensing results in a time sequence, and each historical activity sensing result, for example, includes a sensing time, a roll angle value, and a pitch angle value. After the processing unit 17 obtains the test shooting result and the activity sensing record, the processing unit 17 transmits the test shooting result to the user device, for example, when wireless communication is established with the user device, so that the user device can display the test shooting result for the user to view. Furthermore, when the processing unit 17 receives a setting instruction indicating a designated time point during the test shooting period, the processing unit 17 selects one designated historical activity sensing result whose sensing time is closest to the designated time point from the historical activity sensing results, and determines the standard rolling angle and the standard pitching angle according to the rolling angle value and the pitching angle value of the designated historical activity sensing result, thereby generating the standard posture data including the standard rolling angle and the standard pitching angle, wherein the setting instruction may, for example, come from the user device and is generated by the user device according to the user's operation. In this way, the user can first operate the shooting device 1 to shoot for a period of time (i.e., the test shooting period), then watch the test shooting results on the user device, and operate the user device according to the frames in the test shooting results with suitable shooting angles and good viewing experience to transmit the setting instruction indicating the designated time point to the processing unit 17, so that the processing unit 17 selects the designated historical activity sensing result according to the setting instruction, and sets the standard posture data according to the designated historical activity sensing result. It is additionally explained that the designated time point indicated by the setting instruction is the time point corresponding to one frame of the test shooting result in the entire test shooting result.

[0036] Further, after the processing unit 17 obtains the standard posture data, the processing unit 17 is also used to receive a real-time activity sensing result updated over time from the activity sensing unit 13 during the shooting process of the shooting lens unit 16, wherein the real-time activity sensing result indicates the real-time rotation of the housing 11 in the roll rotation direction R1 and the pitch rotation direction R2. In addition, the processing unit 17 is also used to compare the real-time activity sensing result with the standard posture data, and according to the comparison result of the real-time activity sensing result with the standard posture data, control the first rotation unit 14 and the second rotation unit 15 to rotate in the opposite direction of the housing 11 in the roll rotation direction R1 and the pitch rotation direction R2 in real time, so that the rotation amount of the shooting lens unit 16 in the roll rotation direction R1 and the pitch rotation direction R2 in the real environment is less than the rotation amount of the housing 11 in the roll rotation direction R1 and the pitch rotation direction R2 in the real environment. It is additionally explained that, in the present embodiment, the processing unit 17 controls a micro motor (not shown) to rotate, so that the micro motor further drives the first rotating unit 14 and the second rotating unit 15 to rotate, but the present invention is not limited thereto.

[0037] In more detail, in the present embodiment, the real-time activity sensing result has a roll rotation angle corresponding to the roll rotation direction R1, and a pitch rotation angle corresponding to the pitch rotation direction R2, wherein the roll rotation angle indicates the real-time rotation direction and rotation amount of the shell 11 in the roll rotation direction R1 in the real environment, and the pitch rotation angle indicates the real-time rotation direction and rotation amount of the shell 11 in the pitch rotation direction R2 in the real environment. Moreover, since the real-time activity sensing result is continuously updated over time, the roll rotation angle and the pitch rotation angle are also equivalent to indicating the rotation speed of the shell 11 in the roll rotation direction R1 and the pitch rotation direction R2 in the real environment.

[0038] Furthermore, the processing unit 17 compares the real-time activity sensing result with the standard posture data, for example, by comparing the roll angle of the real-time activity sensing result with the standard roll angle of the standard posture data, and determining whether the difference between the roll angle and the standard roll angle is within a pre-set allowable roll angle difference range. Furthermore, if the determination result of the processing unit 17 is no, the processing unit 17 determines a roll compensation angle corresponding to the roll angle according to the roll angle, and controls the first rotating unit 14 to rotate synchronously and at a constant speed in the opposite direction to the housing 11 in real time according to the roll compensation angle.

[0039] The processing unit 17 compares the real-time activity sensing result with the standard posture data, for example, further including comparing the pitch rotation angle of the real-time activity sensing result with the standard pitch angle of the standard posture data, and judging whether the difference between the pitch rotation angle and the standard pitch angle is within a pre-set allowable difference range of the pitch angle. Moreover, if the judgment result of the processing unit 17 is no, the processing unit 17 determines a pitch compensation angle corresponding to the pitch rotation angle according to the pitch rotation angle, and controls the second rotation unit 15 to rotate synchronously and at a constant speed in the opposite direction to the housing 11 in real time according to the pitch compensation angle.

[0040] by Figure 3 For example, when the housing 11 moves along the rolling rotation direction R1 Figure 3 When the clockwise rolling direction rr1 shown is rotated, the rolling rotation angle of the real-time activity sensing result will indicate the clockwise rolling direction rr1 and the rotation amount of the housing 11 in the clockwise rolling direction rr1. In this case, if the processing unit 17 determines that the difference between the rolling rotation angle and the standard rolling angle is not within the allowable difference range of the rolling angle, the processing unit 17 will, for example, determine a rolling compensation angle with an angle size consistent with the rolling rotation angle based on the rolling rotation angle, and control the first rotating unit 14 to move at a constant speed toward Figure 3 A counterclockwise rolling direction rr2 is shown which is opposite to the clockwise rolling direction rr1 . By controlling the first rotating unit 14 to rotate at a constant speed in the opposite direction to the shell 11 in the rolling rotation direction R1, assuming that a user wears a helmet equipped with the shooting device 1 and rides a motorcycle (or bicycle) and turns left, although the shell 11 of the shooting device 1 will rotate in the clockwise rolling direction rr1 in the rolling rotation direction R1 in the real environment as the motorcycle tilts when turning left, the processing unit 17 will control the first rotating unit 14 to rotate at a constant speed relative to the shell 11 in the counterclockwise rolling direction rr2 opposite to the clockwise rolling direction rr1 during the process of the shell 11 rotating in the clockwise rolling direction rr1, thereby making the rotation of the first rotating unit 14 relative to the shell 11 in the rolling rotation direction R1 and the rotation of the shell 11 in the rolling rotation direction R1 relative to the real environment offset each other, which is equivalent to preventing the shooting lens unit 16 from rotating in the rolling rotation direction R1 in the real environment (equivalent to maintaining stillness in the rolling rotation direction R1 in the real environment). In this way, this embodiment can prevent the video image of the camera unit 16 from being severely tilted as the motorcycle turns. Therefore, this embodiment helps to keep the video image level when the user turns the motorcycle or tilts his head left or right, so that the video image can provide a better viewing experience.

[0041] by Figure 4 For another example, when the housing 11 is tilted in the pitch rotation direction R2, Figure 4 When the lower pitch direction rp1 shown is rotated, the roll rotation angle of the real-time activity sensing result will indicate the lower pitch direction rp1 and the rotation amount of the housing 11 toward the lower pitch direction rp1. In this case, if the processing unit 17 determines that the difference between the pitch rotation angle and the standard pitch angle is not within the allowable difference range of the pitch angle, the processing unit 17 will, for example, determine a pitch compensation angle with an angle size consistent with the pitch rotation angle based on the pitch rotation angle, and control the second rotation unit 15 to move toward the lower pitch direction at a constant speed based on the pitch compensation angle. Figure 4 An upward pitch direction rp2 is shown and is opposite to the downward pitch direction rp1. By controlling the second rotating unit 15 to rotate at a constant speed in the opposite direction to the housing 11 in the pitch rotation direction R2, assuming that a user wearing a helmet equipped with the camera 1 lowers his head while riding a motorcycle, although the housing 11 of the camera 1 will rotate toward the lower pitch direction rp1 in the pitch rotation direction R2 in the real environment as the user lowers his head, the processing unit 17 will control the second rotating unit 15 to rotate at a constant speed relative to the housing 11 toward the upward pitch direction rp2 opposite to the lower pitch direction rp1 in real time during the rotation of the housing 11 toward the lower pitch direction rp1, thereby making the rotation of the second rotating unit 15 relative to the housing 11 in the pitch rotation direction R2 and the rotation of the housing 11 relative to the real environment in the pitch rotation direction R2 offset each other, which is equivalent to preventing the shooting lens unit 16 from rotating in the pitch rotation direction R2 in the real environment (equivalent to maintaining stillness in the pitch rotation direction R2 in the real environment). In this way, this embodiment can prevent the camera unit 16 from being unable to capture the environment directly in front of the user due to the user lowering his head. Therefore, this embodiment helps the camera unit 16 to continue to capture the environment directly in front of the user when the user lowers his head or raises his head, thereby reducing the situation where the camera unit 16 fails to capture the environment directly in front of the user due to the user lowering his head or raising his head.

[0042] It is additionally explained that in another embodiment of the present invention, the processing unit 17 may also analyze the rotation of the housing 11 in the roll rotation direction R1 and the pitch rotation direction R2 according to the video image generated by the camera unit 16 by using image recognition technology, and then control the first rotation unit 14 and the second rotation unit 15 to rotate at the same speed in the opposite direction of the housing 11 in the roll rotation direction R1 and the pitch rotation direction R2 respectively in real time. For example, the processing unit 17 may determine the real-time rotation direction and rotation amount of the housing 11 in the roll rotation direction R1 by using the angle change of the road marking in the video image, and on the other hand, the processing unit 17 may determine the real-time rotation direction and rotation amount of the housing 11 in the pitch rotation direction R2 by using the area ratio change of the ground and the sky in the video image. Furthermore, the processing unit 17 can, for example, control the first rotating unit 14 to rotate in the opposite direction to the housing 11 in the roll rotation direction R1, so that the road markings in the video image are maintained at an angle substantially parallel to the left and right boundaries of the video image, thereby achieving stability of the video image in the roll rotation direction R1. On the other hand, the processing unit 17 can, for example, control the second rotating unit 15 to rotate in the opposite direction to the housing 11 in the pitch rotation direction R2, so that the area ratio of the ground and the sky in the video image is maintained within a predetermined ratio range (for example, 2:1 to 2.2:1), thereby achieving stability of the video image in the pitch rotation direction R2.

[0043] In summary, the camera unit 16 can be driven by the first rotating unit 14 to rotate in the roll rotation direction R1, and can also be driven by the second rotating unit 15 to rotate in the pitch rotation direction R2. Moreover, the processing unit 17 controls the first rotating unit 14 to rotate in the opposite direction of the housing 11 in the roll rotation direction R1, and controls the second rotating unit 15 to rotate in the opposite direction of the housing 11 in the pitch rotation direction R2 according to the real-time activity sensing result generated by the activity sensing unit 16, so that the rotation amount of the camera unit 16 in the roll rotation direction R1 and the pitch rotation direction R2 in the real environment is smaller than the rotation amount of the housing 11. Therefore, the shooting device can improve the situation in which the video image of the camera unit 16 is severely tilted due to the movement of the rider's head and fails to present the environment directly in front of the rider, so the purpose of the present invention can be achieved. In addition, by controlling the first rotating unit 14 and the second rotating unit 15 to rotate in the opposite direction to the housing 11 in the rolling rotation direction R1 and the pitching rotation direction R2 by the processing unit 17, this embodiment also helps to prevent the camera 1 from shaking in the rolling rotation direction R1 and the pitching rotation direction R2, causing the recorded image to be blurred.
