[0001] Cross - reference to related applications

[0002] This application claims the benefit of priority to Korean Patent Application No. 10 - 2021 - 0162476, filed on November 23, 2021, with the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference for all purposes. Technical Field

[0003] The following description relates to a sensor shift module and a camera module including the sensor shift module. Background Art

[0004] With the development of communication technologies, mobile devices such as, but not limited to, smart phones have been widely popularized, and accordingly, the demand for increased functions related to cameras included in mobile devices has also increased. For example, a camera included in a mobile device can be implemented to provide advanced imaging functions (e.g., autofocus function, anti - shake function, etc.) that are achieved in a standard digital single - lens reflex (DSLR) camera despite its small size.

[0005] An optical image stabilization function (i.e., an optical image stabilization (OIS) function) can prevent image blurring when a camera shakes during an exposure time, and the OIS function may be necessary when imaging in a low - light environment where the camera shakes and the exposure time is long. OIS can include digital IS (DIS), electronic IS (EIS), and optical IS (OIS). Among these functions, optical IS (OIS) can correct an optical path by moving a lens or an image sensor in a direction orthogonal to an optical axis, thereby fundamentally preventing image degradation caused by shaking. Since a mechanical actuator is required, implementing it as a device may be complex, and although excellent compensation performance can be obtained, the related cost is expensive.

[0006] Since a lens barrel includes an optical system therein, a relatively large amount of force may be required to drive the lens barrel. Since an image sensor is relatively light, an excellent optical image stabilization (OIS) function can be advantageously achieved even with a relatively small amount of force.

[0007] A camera implemented in a mobile device can mainly provide a shake - correction function that only prevents shaking in a direction orthogonal to the optical axis when an image is acquired. Recently, mobile devices have been used for shooting videos, and accordingly, it is desired to move an image sensor in different changing directions to correct shaking in a more dynamic environment.

The AF driver 23 may include, for example, a coil and a magnet that face each other. The coil may be fixedly coupled to the lens module 20, the magnet may be coupled to a fixed body such as a housing, and the electromagnetic interaction between the coil and the magnet may cause the lens module 20 to move in the optical axis direction.

[0054] In an exemplary embodiment, the camera module 1 may provide an optical image stabilization (hereinafter referred to as "OIS") function. The camera module 1 may provide the OIS function by driving the image sensor 11. For example, the camera module 1 may include an OIS driver 12 configured to move the image sensor 11 in a direction orthogonal to the optical axis, or to rotate the image sensor 11 about an axis parallel to the optical axis, or to rotate the image sensor 11 about an axis perpendicular to the optical axis.

For example, the second optical element 40 may be implemented as a prism or a mirror.

[0058] Hereinafter, the sensor shift module 100 described with reference to Figures 2A to 7B may be applied to the camera module 1 in Figure 1 .

[0061] The sensor shift module 100 may include an OIS driver. The OIS driver may include at least one of a first OIS driver, a second OIS driver, and a third OIS driver to be described later. The first OIS driver may move the image sensor 111 in a direction orthogonal to the optical axis, the second OIS driver may rotate the image sensor 111 about an axis parallel to the optical axis, and the third OIS driver may rotate the image sensor 111 about an axis orthogonal to the optical axis.

[0064] 2.1.1. Structure

[0065] The sensor shift module 100 may include a first OIS driver that drives the image sensor 111. In an exemplary embodiment, the sensor shift module 100 may include a second movable body 110 and a first movable body 130. The second movable body 110 includes the image sensor 111, and the first movable body 130 supports and moves the second movable body 110. The second movable body 110 may be movably disposed in or on the first movable body 130. The second movable body 110 may be configured to move together with the image sensor 111. For example, the second movable body 110 may include a sensor substrate 112 on which the image sensor 111 is mounted and a sensor bracket 113 coupled to the sensor substrate 112. The first movable body 130 may move relative to the fixed body 170 in a direction orthogonal to the optical axis by the first OIS driver, so that the second movable body 110 moves relative to the fixed body 170 in a direction orthogonal to the optical axis.

[0066] Reference Figure 2B , the signal of the image sensor 111 may be transmitted to another electronic component (e.g., an image signal processor (ISP)) through the sensor substrate 112 and the connector.

[0067] In an exemplary embodiment, the sensor shift module 100 may include a first OIS driver that moves the image sensor 111 in a direction orthogonal to the optical axis O. The second movable body 110 may move relative to the fixed body 170 in a direction orthogonal to the direction in which the imaging surface 111a of the image sensor 111 points by the first OIS driver. In an exemplary embodiment, the first OIS driver may correct the jitter of the camera module 1 or the electronic device on which the image sensor 111 is mounted in a direction orthogonal to the optical axis O. In an exemplary embodiment, the first OIS driver may move the image sensor 111 in a first direction and a second direction orthogonal to the optical axis O. The first direction and the second direction may intersect with each other. For example, the first OIS driver may move the second movable body 110 in the X direction and / or the Y direction orthogonal to the Z axis, so as to correct the jitter in the X direction and / or the Y direction.

[0068] In an exemplary embodiment, the direction in which the imaging surface 111a of the image sensor 111 points may be referred to as the optical axis O direction. That is, the second movable body 110 may move relative to the first movable body 130 in a direction orthogonal to the optical axis O. In the drawings, the optical axis O may be parallel to the Z axis, and thus, the Z direction may refer to the direction parallel to the optical axis O. In addition, the X direction or the Y direction may refer to a direction orthogonal to the optical axis O. For example, in an exemplary embodiment, the configuration in which the second movable body 110 moves in the X direction may indicate that the second movable body 110 may move in a direction orthogonal to the optical axis O. For another example, the configuration in which the drive magnet 121 and the drive coil 122 face each other in the X direction may indicate that the drive magnet 121 and the drive coil 122 face each other in a direction orthogonal to the optical axis O. In addition, the X direction or the Y direction may be an example of two directions that are orthogonal to the optical axis and intersect each other, and in an exemplary embodiment, the X direction and the Y direction may be configured as two directions that are orthogonal to the optical axis O and intersect each other.

[0069] In an exemplary embodiment, the sensor shift module 100 may include a second OIS driver that rotates the image sensor 111 about an axis parallel to the optical axis O. The second movable body 110 may rotate relative to the fixed body 170 about an axis parallel to the direction in which the imaging surface 111a of the image sensor 111 points by the second OIS driver. In an exemplary embodiment, the second OIS driver may correct the rotation of the camera module 1 or the electronic device on which the image sensor 111 is mounted about an axis parallel to the optical axis O.

[0070] 2.1.2 First actuator (translation)

[0071] Refer to Figure 2A and Figure 2B , in an exemplary embodiment, the first OIS driver may include a first actuator 120 disposed between the fixed body 170 and the second movable body 110. In an exemplary embodiment, the first actuator 120 may include a first drive magnet 121 coupled to the second movable body 110 and a first drive coil 122 coupled to the fixed body 170. For example, refer to Figure 2A, in an exemplary embodiment, the first driving coil 122 may be coupled to the inner surface of the fixed body 170, and the first driving magnet 121 may be coupled to one side surface of the second movable body 110. However, this is a non-limiting example, and in an example, the first driving coil 122 may be coupled to one side surface of the second movable body 110, and the first driving magnet 121 may be coupled to the inner surface of the fixed body 170. The first driving magnet 121 and the first driving coil 122 may face each other in a direction orthogonal to the optical axis O (e.g., the X direction or the Y direction). The electromagnetic interaction between the first driving magnet 121 and the first driving coil 122 may cause the first movable body 130 to move relative to the fixed body 170 in a direction orthogonal to the optical axis O.

[0072] The first OIS driver may include a plurality of first actuators 120, and each of the first actuators 120 may include a first driving magnet 121 and a first driving coil 122. For example, the first OIS driver may include a 1-1 actuator 120-1 disposed on the first side surface 110a-1 of the second movable body 110 and a 1-2 actuator 120-2 disposed on the second side surface 110a-2 of the second movable body 110. Refer to Figure 2B , the 1-1 actuator 120-1 may include a 1-1 driving magnet 121-1 and a 1-1 driving coil 122-1. The 1-2 actuator 120-2 may include a 1-2 driving magnet 121-2 and a 1-2 driving coil 122-2.

[0073] In an exemplary embodiment, the first OIS driver may further include a yoke 123 disposed on one side of the first driving magnet 121 and / or the first driving coil 122. The yoke 123 attached to one side of the first driving coil 122 may concentrate the magnetic field generated by the first driving coil 122 in the direction toward the first driving magnet 121. Since the yoke 123 is disposed on one side of the first driving coil 122, the magnetic field generated by the first driving coil 122 can be prevented from affecting other electronic components, or the influence of the magnetic field on other electronic components can be reduced. The yoke 123 attached to one side of the first driving magnet 121 may concentrate the magnetic field generated by the first driving magnet 121 in the direction toward the first driving coil 122.

[0074] In an exemplary embodiment, the first driving coil 122 and the first driving magnet 121 may be respectively coupled to the fixed body 170 and the second movable body 110, but the exemplary embodiment is not limited thereto. In another exemplary embodiment, the first driving coil 122 and the first driving magnet 121 may be respectively coupled to the second movable body 110 and the fixed body 170.

[0075] 2.1.3 Second Actuator (Rolling)

[0076] Referring to Figure 2A and Figure 2B In an exemplary embodiment, the second OIS driver may include a second actuator 150 disposed between the fixed body 170 and the second movable body 110. In an exemplary embodiment, the second actuator 150 may include a second drive magnet 151 coupled to the second movable body 110 and a second drive coil 152 coupled to the fixed body 170. However, this is merely an example, and in the example, the second drive magnet 151 may be coupled to the fixed body 170, and the second drive coil 152 may be coupled to the second movable body 110.

[0077] Referring to Figure 2A In an exemplary embodiment, the second drive coil 152 and the second drive magnet 151 may be respectively coupled to the inner surface of the fixed body 170 and a side surface of the second movable body 110. The second drive magnet 151 and the second drive coil 152 may face each other in a direction orthogonal to the optical axis O. The electromagnetic interaction between the second drive magnet 151 and the second drive coil 152 may rotate the first movable body 130 about an axis parallel to the optical axis O with respect to the fixed body 170.

[0078] The second OIS driver may include a plurality of second actuators 150, and each of the second actuators 150 may include a second drive magnet 151 and a second drive coil 152. For example, the second OIS driver may include a 2-1 actuator 150-1 disposed on the third side surface 110a-3 of the second movable body 110 and a 2-2 actuator 150-2 disposed on the fourth side surface 110a-4 of the second movable body 110. Referring to Figure 2B In, the 2-1 actuator 150-1 may include a 2-1 drive magnet 151-1 and a 2-1 drive coil 152-1. The 2-2 actuator 150-2 may include a 2-2 drive magnet 151-2 and a 2-2 drive coil 152-2.

[0079] In an exemplary embodiment, the second OIS driver may further include a yoke 153 disposed on one side of the second drive magnet 151 and / or the second drive coil 152. The yoke 153 attached to one side of the second drive coil 152 may concentrate the magnetic field generated by the second drive coil 152 in the direction toward the second drive magnet 151. Since the yoke 153 is disposed on one side of the second drive coil 152, the magnetic field generated by the second drive coil 152 can be prevented from affecting other electronic components, or the influence of the magnetic field on other electronic components can be reduced. The yoke 153 attached to one side of the second drive magnet 151 may concentrate the magnetic field generated by the second drive magnet 151 in the direction toward the second drive coil 152.

[0080] In an exemplary embodiment, the second driving coil 152 and the second driving magnet 151 may be coupled to the fixed body 170 and the second movable body 110, respectively. However, the example is not limited thereto, and in another exemplary embodiment, the second driving coil 152 and the second driving magnet 151 may be coupled to the second movable body 110 and the fixed body 170, respectively.

[0081] 2.1.4. Ball guide / support

[0082] Based on the operations performed by the first OIS driver or the second OIS driver, the first movable body 130 (or the second movable body 110) may move in a plane perpendicular to the optical axis O. The movement of the first movable body 130 may be supported by the support ball 141. The support ball 141 may be included in a part of the first OIS driver or the second OIS driver.

[0083] Based on the operation of the third OIS driver, the second movable body 110 may rotate about an axis perpendicular to the optical axis O. The movement of the second movable body 110 may be supported by the tilt guide ball 164.

[0084] The first movable body 130 may be disposed between the second movable body 110 and the fixed body 170. For example, the first movable body 130 may be disposed between the lower surface 110d of the second movable body 110 and the bottom surface 171 of the fixed body 170. The first movable body 130 may guide or support the movement of the second movable body 110. The second movable body 110 may rotate and be supported by the tilt guide ball 164 disposed on the first movable body 130 and between the second movable body 110 and the first movable body 130. The first movable body 130 may be disposed on the bottom surface 171 of the fixed body 170 and may move in a plane perpendicular to the optical axis O such that the second movable body 110 may move relative to the fixed body 170 in a plane perpendicular to the optical axis O.

[0085] Figure 3 An exemplary arrangement of the support ball 141 according to one or more embodiments is shown.

[0086] Refer to Figure 2A and the support ball 141 may be disposed between the lower surface 131 of the first movable body 130 and the bottom surface 171 of the fixed body 170. For example, refer to Figure 3, three support balls 141 may be disposed on the bottom surface 171 of the fixed body 170. The first movable body 130 and the fixed body 170 may include grooves that partially accommodate the support balls 141. For example, a first groove 142 and a second groove 143 may be respectively disposed in the fixed body 170 and the first movable body 130. Although three support balls 141 are shown, this is merely an example, and the number of support balls 141 may include less than or more than three.

[0087] At least one of the first groove 142 and the second groove 143 may be configured such that the support ball 141 can move within a predetermined range in a direction perpendicular to the optical axis O relative to the fixed body 170 or the first movable body 130. For example, the second groove 143 may be formed to contact the support ball 141 at at least one point, and the support ball 141 may roll or slide within the second groove 143 within a predetermined range. Accordingly, the first movable body 130 or the second movable body 110 may move relative to the fixed body 170 in a plane perpendicular to the optical axis O by the first OIS driver or the second OIS driver.

[0088] In an exemplary embodiment, the first OIS driver may include a first position sensor that can measure how much the second movable body 110 has moved in a direction orthogonal to the optical axis O. The first position sensor may be configured as a Hall sensor or a magnetoresistive sensor. In an exemplary embodiment, the first position sensor may be disposed in the first drive coil 122 to face the first drive magnet 121.

[0089] In another exemplary embodiment, the first OIS driver may include a sensing magnet different from the first drive magnet 121, and the first position sensor may be disposed to face the sensing magnet.

[0092] The second position sensor may be the same component as the first position sensor. That is, one position sensor may be used to measure the translational motion (by the motion of the first OIS driver) and the rotational motion (by the motion of the second OIS driver) of the second movable body.

[0094] Figure 4A and Figure 4B The arrangement of the first OIS driver 120 and the second OIS driver 150 according to one or more embodiments is shown.

The side surface 110a of the second movable body 110 may be the side surface of the sensor bracket 113.

[0097] In an exemplary embodiment, the four side surfaces 110a-1, 110a-2, 110a-3, 110a-4 may be parallel to the horizontal side 111b or the vertical side 111c of the image sensor 111, and the four corners 110b may be provided in the diagonal directions D1 and D2 of the image sensor 111.

[0098] The first actuator (or the first OIS driver) 120 and the second actuator (or the second OIS driver) 150 may be disposed on different side surfaces among the four side surfaces 110a-1, 110a-2, 110a-3, and 110a-4. For example, the 1-1 actuator 120-1, the 1-2 actuator 120-2, the 2-1 actuator 150-1, and the 2-2 actuator 150-2 may be disposed on the first side surface 110a-1, the second side surface 110a-2, the third side surface 110a-3, and the fourth side surface 110a-4, respectively.

[0099] Referring to Figure 4A and Figure 4B , the second actuator 150 included in the second OIS driver may be disposed adjacent to the corner 110b of the second movable body 110. Since the second actuator 150 is disposed adjacent to the corner 110b, the second movable body 110 can be effectively rotated.

[0100] Referring to Figure 4A , the 1-1 actuator 120-1 and the 1-2 actuator 120-2 included in the first OIS driver may be disposed at the centers of the first side surface 110a-1 and the second side surface 110a-2. The 2-1 actuator 150-1 and the 2-2 actuator 150-2 included in the second OIS driver may be disposed on the third side surface 110a-3 and the fourth side surface 110a-4, respectively.

The 2-1 actuator 150-1 and the 2-2 actuator 150-2 may be disposed adjacent to the third corner 110b-3 and the fourth corner 110b-4, respectively.

[0102] 2.2. Tilt OIS

[0103] 2.2.1. Structure

[0104] Referring to Figure 2A , the sensor shift module 100 may include a third OIS driver. The sensor shift module 100 may include a third OIS driver that rotates the second movable body 110 relative to the first movable body 130. The third OIS driver may rotate about an axis orthogonal to the optical axis O (e.g., Figure 2BRotate the second movable body 110 about the first axis A1 or the second axis A2). Jitter correction can be achieved by translating the image sensor 111 in a direction orthogonal to the optical axis O. However, since the size of the mobile camera is relatively small, the range of the translational movement may be relatively small, and thus, when the degree of jitter is relatively large, the correction amount may not reach the amount of jitter. The third OIS driver can correct jitter by tilting the image sensor 111 and can provide an excellent quality jitter correction function even for relatively large jitter.

[0105] 2.2.2. Third actuator (tilt)

[0108] In an exemplary embodiment, the third drive magnet 161 may be the first drive magnet 121 of the first OIS driver or the second drive magnet 151 of the second OIS driver. That is, the first drive magnet 121 or the second drive magnet 151 may be included in a part of the third OIS driver. For example, at least one of the 1-1 drive magnet 121-1, 1-2 drive magnet 121-2, 2-1 drive magnet 151-1, or 2-2 drive magnet 151-2 may be implemented as the third drive magnet 161.

The 3-1 drive coil 162-1, the 3-2 drive coil 162-2, the 3-3 drive coil 162-3, and the 3-4 drive coil 162-4 may be arranged to face the 1-1 drive magnet 121-1, the 1-2 drive magnet 121-2, the 2-1 drive magnet 151-1, and the 2-2 drive magnet 151-2 respectively.

[0114] The 3-1 actuator 160-1 or the 3-3 actuator 160-3 may provide a torque to the second movable body 110 in the direction of the first axis A1. When a current is applied to the 3-1 drive coil 162-1, an attractive or repulsive force may be generated between the 3-1 drive coil 162-1 and the 1-1 drive magnet 121-1, such that the second movable body 110 may be tilted with respect to the first movable body 130 about the first axis A1 orthogonal to the optical axis.

As another example, the third OIS driver may include only the 3-3 actuator 160-3 and the 3-4 actuator 160-4.

[0117] 2.2.3. Ball guide

[0118] In an exemplary embodiment, the third OIS driver may include an inclined guide ball 164 disposed between the second movable body 110 and the first movable body 130. The inclined guide ball 164 can provide a tilting center for the second movable body 110. For example, the second movable body 110 can tilt around the inclined guide ball 164. Referring to Figure 2A , the lower surface 110d of the second movable body 110 and the upper surface 132 of the first movable body 130 can face each other in the direction of the optical axis O, and grooves for partially accommodating the inclined guide ball 164 can be formed in the lower surface 110d of the second movable body 110 and the upper surface 132 of the first movable body 130, respectively.

[0119] 2.2.4. Traction

A magnetic attraction may be generated between the first magnetic member 165 and the second magnetic member 166, such that the second movable body 110 may be pulled onto the upper surface 132 of the first movable body 130. Accordingly, the tilt guiding ball 164 may remain in contact with the first movable body 130 and the second movable body 110, such that the second movable body 110 may tilt smoothly with respect to the first movable body 130.

[0122] In an example, one of the first magnetic member 165 or the second magnetic member 166 may be a magnet, and the other may be a magnet or a magnetic yoke. For example, the first magnetic member 165 may be a magnet, and the second magnetic member 166 may be a magnetic yoke.

[0123] Referring to Figure 2C , a plurality of second magnetic members 166 may be disposed around the tilt guiding ball 164.

[0128] 2.3.1. Translational movement

[0130] Referring to Figure 5A , the 1-1 actuator 120-1 can move the second movable body 110 relative to the fixed body 170 in the X direction. When current is applied to the 1-1 drive coil 122-1, an attractive or repulsive force in the X direction can be generated between the 1-1 drive coil 122-1 and the 1-1 drive magnet 121-1, so that the second movable body 110 (or the image sensor 111) can move in the -X direction or the +X direction.

[0131] Referring to Figure 5B , the 1-2 actuator 120-2 can move the second movable body 110 relative to the fixed body 170 in the Y direction. When current is applied to the 1-2 drive coil 122-2, an attractive or repulsive force in the Y direction can be generated between the 1-2 drive coil 122-2 and the 1-2 drive magnet 121-2, so that the second movable body 110 (or the image sensor 111) can move in the -Y direction or the +Y direction.

[0132] 2.3.2. Rolling motion

[0133] Figure 6A and Figure 6B Shows the rolling of the second movable body 110.

[0134] Referring to Figure 6A , the 2-1 actuator 150-1 and the 2-2 actuator 150-2 can rotate the second movable body 110 relative to the fixed body 170 in the counterclockwise direction. The 2-1 actuator 150-1 and the 2-2 actuator 150-2 can provide a torque to the second movable body 110 in the counterclockwise direction. For example, a Lorentz force can be generated between the 2-1 drive magnet 151-1 and the 2-1 drive coil 152-1, and thus, the force F1 can act on the 2-1 drive magnet 151-1. A Lorentz force can be generated between the 2-2 drive magnet 151-2 and the 2-2 drive coil 152-2, and thus, the force F2 can act on the 2-2 drive magnet 151-2. The forces F1 and F2 can rotate the second movable body 110 in the counterclockwise direction.

[0135] Referring to Figure 6B, the 2-1 actuator 150-1 and the 2-2 actuator 150-2 can rotate the second movable body 110 relative to the fixed body 170 in the clockwise direction. The 2-1 actuator 150-1 and the 2-2 actuator 150-2 can provide a torque in the clockwise direction to the second movable body 110. For example, a Lorentz force can be generated between the 2-1 drive magnet 151-1 and the 2-1 drive coil 152-1, and thus, the force F3 can act on the 2-1 drive magnet 151-1. A Lorentz force can be generated between the 2-2 drive magnet 151-2 and the 2-2 drive coil 152-2, and thus, the force F4 can act on the 2-2 drive magnet 151-2. The forces F3 and F4 can rotate the second movable body 110 in the clockwise direction.

[0136] 2.3.3. Tilt movement

[0137] Figure 7A and Figure 7B shows the tilt of the second movable body 110.

[0138] Referring to Figure 7A and Figure 7B , the third OIS driver can rotate the image sensor 111 about an axis orthogonal to the optical axis. For example, the third OIS driver can rotate the second movable body 110 relative to the tilt guide ball 164 in the clockwise or counterclockwise direction.

[0139] Figure 7A and Figure 7B show the 3-1 actuator 160-1 and the 3-3 actuator 160-3 responsible for rotating the second movable body 110 in the direction of the first axis A1 (or the Y-axis direction). Although not shown, the second movable body 110 can be rotated about different axes orthogonal to the optical axis (e.g., Figure 2B the first axis A1 or the second axis A2 in

[0140] Referring to Figure 7A , when a current is applied to the 3-1 drive coil 162-1, a repulsive force can be generated between the 3-1 drive magnet 161-1 and the 3-1 drive coil 162-1, such that the second movable body 110 can rotate in the counterclockwise direction. Additionally or alternatively, when a current is applied to the 3-3 drive coil 162-3, an attractive force can be generated between the 3-3 drive magnet 161-3 and the 3-3 drive coil 162-3, such that the second movable body 1310 can rotate relative to the first movable body 130 in the counterclockwise direction.

[0141] Referring to Figure 7B, when a current is applied to the 3-1 drive coil 162-1, an attractive force can be generated between the 3-1 drive magnet 161-1 and the 3-1 drive coil 162-1, so that the second movable body 110 can rotate in the clockwise direction. Additionally or alternatively, when a current is applied to the 3-3 drive coil 162-3, a repulsive force can be generated between the 3-3 drive magnet 161-3 and the 3-3 drive coil 162-3, so that the second movable body 110 can rotate relative to the first movable body 130 in the clockwise direction.

[0142] In an exemplary embodiment, one of the 3-1 actuator 160-1 and the 3-3 actuator 160-3 in the third OIS driver may not be provided. This is because the 3-1 actuator 160-1 and the 3-3 actuator 160-3 can rotate the first movable body 130 in the clockwise or counterclockwise direction.

[0143] According to the foregoing exemplary embodiment, the camera can provide effective optical image stabilization operation with low power. Additionally, an excellent shake correction function can be achieved by driving the image sensor in various directions.
