Description

Camera assembly and electronic device including it

[0001] The various embodiments disclosed in this document relate to a camera assembly and an electronic device including the same.

[0002] Various electronic devices such as smartphones, tablet PCs, portable multimedia players (PMPs), personal digital assistants (PDAs), laptop personal computers, wristwatches, and wearable devices like head-mounted displays (HMDs) include cameras and can take images using the cameras.

[0003] As the number of users taking photos or videos using electronic devices increases, the performance of cameras included in these devices is also improving. For example, when capturing images using a camera included in an electronic device, it may be necessary to adjust the focus of the subject or correct for shaking (e.g., hand shake) that may occur during shooting in order to obtain a sharp image.

[0004] The information described above may be provided as related art for the purpose of aiding understanding of the present disclosure. No claim or determination is made as to whether any of the foregoing may be applied as prior art related to the present disclosure.

[0005] In the case of electronic devices including cameras, components that adjust the focus of the subject can be omitted to make the electronic device thin. However, as the size of the image sensor in the electronic device's camera increases, the focal length (e.g., the distance from the center of the camera lens to the image sensor) becomes longer, resulting in a phenomenon where the overall depth of field becomes shallow. Consequently, there is an increasing demand for components that can adjust the depth of field according to user requirements.

[0006] In the case of an electronic device including an aperture, the incident area of ​​the camera lens may include a minimum opening state and a maximum opening state due to the multiple blades of the aperture. Light may exhibit diffraction, a phenomenon in which it is refracted and spreads like a wave when passing through a narrow gap. When the multiple blades are adjusted to the minimum opening state to increase depth of field, diffraction may occur in the narrow gap formed by the multiple blades. This may affect the phase difference calculation information of the camera image sensor, thereby degrading the camera image quality.

[0007] The technical tasks intended to be accomplished in this document are not limited to those mentioned above, and other technical tasks not mentioned will be clearly understood by those skilled in the art to which this document belongs from the description below.

The lens assembly (210) may collect light emitted from a subject that is the target of image capture. The lens assembly (210) may include one or more lenses. According to one embodiment, the camera assembly (180) may include a plurality of lens assemblies (210). In this case, the camera assembly (180) may form, for example, a dual camera, a 360-degree camera, or a spherical camera. Some of the plurality of lens assemblies (210) may have the same lens properties (e.g., angle of view, focal length, autofocus, f-number, or optical zoom), or at least one lens assembly may have one or more lens properties different from the lens properties of other lens assemblies. The lens assemblies (210) may include, for example, a wide-angle lens or a telephoto lens.

An image sensor (230) may acquire an image corresponding to the subject by converting light emitted or reflected from the subject and transmitted through a lens assembly (210) into an electrical signal. According to one embodiment, the image sensor (230) may include one image sensor selected from image sensors with different properties, such as an RGB sensor, a BW (black and white) sensor, an IR sensor, or a UV sensor, a plurality of image sensors having the same properties, or a plurality of image sensors having different properties. Each image sensor included in the image sensor (230) can be implemented using, for example, a CCD (charged coupled device) sensor or a CMOS (complementary metal oxide semiconductor) sensor.

[0067] The image stabilizer (240) can move at least one lens or image sensor (230) included in the lens assembly (210) in a specific direction or control the operational characteristics of the image sensor (230) (e.g., adjusting read-out timing, etc.) in response to the movement of the camera assembly (180) or the electronic device (100) including it. This allows at least some of the image shake caused by the movement to be compensated for in the image being captured. According to one embodiment, the image stabilizer (240) can detect such movement of the camera assembly (180) or the electronic device (100) using a gyroscope sensor (not shown) or an accelerometer sensor (not shown) placed inside or outside the camera assembly (180). The memory (250) can temporarily store at least some of the image acquired through the image sensor (230) for the next image processing operation. For example, if image acquisition by the shutter is delayed or multiple images are acquired at high speed, the acquired original image (e.g., a Bayer-patterned image or a high-resolution image) is stored in memory (250), and the corresponding copy image (e.g., a low-resolution image) can be previewed through the display module (160). Subsequently, when a specified condition is satisfied (e.g., user input or system command), at least a portion of the original image stored in memory (250) can be acquired and processed by, for example, an image signal processor (260). According to one embodiment, memory (250) may be configured as at least a portion of memory (130) or as a separate memory that operates independently thereof.

[0068] The image signal processor (260) can perform one or more image processing operations on an image obtained through the image sensor (230) or an image stored in memory (250). One or more of the above image processing may include, for example, depth map generation, 3D modeling, panorama generation, feature point extraction, image synthesis, or image compensation (e.g., noise reduction, resolution adjustment, brightness adjustment, blurring, sharpening, or softing). Additionally or generally, the image signal processor (260) may perform control (e.g., exposure time control, or readout timing control, etc.) over at least one of the components included in the camera assembly (180) (e.g., image sensor (230)). The image processed by the image signal processor (260) may be stored back in memory (250) for further processing or provided to an external component of the camera assembly (180) (e.g., memory (130), display module (160), electronic device (102), electronic device (104), or server (108)). According to one embodiment, the image signal processor (260) is at least part of the processor (120). It may be configured as a separate processor that operates independently of the processor (120). If the image signal processor (260) is configured as a separate processor from the processor (120), at least one image processed by the image signal processor (260) may be displayed through the display module (160) as is or after additional image processing by the processor (120).

In this case, for example, the plurality of camera assemblies (180) may include at least one of a wide-angle camera, a telephoto camera, or an IR camera (time of flight camera, structured light camera). For example, a plurality of camera assemblies may be configured, each including a lens having a different angle of view, and the electronic device may be controlled to change the angle of view by varying according to the user's selection.

In a de-focus situation, the electrical data values ​​of a plurality of light-receiving elements (631-1, 631-2, 632-1, 632-2, 633-1, 633-2, 634-1, 634-2) arranged in left and right directions may differ. Based on the electrical data comparison values ​​provided by the data calculation unit (340), the processor (e.g., the processor (110) of FIG. 1b) can calculate the position of the focus or the direction of the focus where the electrical data comparison values ​​are minimized.

[0097] In one embodiment, referring to FIG. 4a, the phase difference detection operation may include a horizontal (e.g., left-right direction) phase difference detection operation between light receiving elements arranged adjacently in the horizontal direction (e.g., first-1 light receiving element (631-1) and first-2 light receiving element (631-2)). For example, the phase difference detection operation of the first-2 PD unit pixel (602-1) may include a horizontal phase difference detection operation between the first-1 light receiving element (631-1) and the first-2 light receiving element (631-2) arranged adjacently in the horizontal direction. In one embodiment, the horizontal phase difference detection operation may be performed in a direction parallel to the x-axis, a direction perpendicular to the y-axis, a direction perpendicular to the first straight line (e.g., the third straight line (550) in FIG. 8a), or a direction parallel to the fourth straight line (e.g., the fourth straight line (570) in FIG. 8a).

The comparison value of the detected electrical data can be utilized for horizontal phase difference AF (auto focusing). For example, a processor (e.g., processor (110) of FIG. 1b) can use the comparison value of the electrical data of the first-1 light receiving element (631-1) and the electrical data of the first-2 light receiving element (631-2) for the horizontal phase difference calculation of the data calculation unit (340).

[0099] In one embodiment, referring to FIGS. 3 and FIGS. 4a, electrical data output from a plurality of light receiving elements (631-1, 631-2, 632-1, 632-2, 633-1, 633-2, 634-1, 634-2) can be used in a data processing unit (340). Based on the electrical data comparison value provided by the data processing unit (340), a processor (e.g., processor (110) of FIG. 1b) can construct an image that is stored in a memory (e.g., memory (120) of FIG. 1a).

The processor (e.g., processor (110) of FIG. 1b) can control the aperture assembly (500) so that the incident area (A1, A2) is reduced in a relatively bright environment. The aperture assembly (500) can vary the size of the incident area (A1, A2) depending on the degree of opening. For example, when the aperture assembly (500) is in a maximum opening state, the size of the incident area (A1) can also be maximum.

[0149] In one embodiment, referring to FIGS. 6, 7a, and 7b, the aperture assembly (500) may include a first incident area (A1) and a second incident area (A2) that is narrower than the first incident area (A1) depending on the degree of opening. In one embodiment, the first incident area (A1) and the second incident area (A2) may be formed in a circular shape. In one embodiment, the first incident area (A1) and the second incident area (A2) may be formed in a polygonal shape.

[0150] In one embodiment, referring to FIGS. 6 and FIGS. 7a, the second incident region (A2) may be formed when the aperture assembly (500) is minimally open.

[0151] In one embodiment, referring to FIG. 7b, the first incident region (A1) can be formed when the aperture assembly (500) is maximally open.

[0152] In one embodiment, referring to FIGS. 6 and FIGS. 7a, the aperture assembly (500) may include a first blade (510) and a second blade (520) that form a second incident area (A2). The inner surface (511) of the first blade (510) and the inner surface (521) of the second blade (520) may form the second incident area (A2). The first side (510C) of the first blade (510) and the first side (520C) of the second blade (520) may form the second incident area (A2).

[0153] In one embodiment, with reference to FIGS. 6 and 7a, and FIGS. 8a and 8b to be described later, the first blade (510) and the second blade (520) may be formed symmetrically with respect to the optical axis (C) of the lens (411). The first blade (510) and the second blade (520) may be formed in a shape corresponding to the optical axis (C) of the lens (411). For example, the inner surface (511), the first side (510C), the outer surface (512), the first surface (510a), and the second surface (510b) of the first blade (510) may each be formed in a shape corresponding to the inner surface (521), the first side (520C), the outer surface (522), the first surface (520a), and the second surface (520b) of the second blade (520). The first blade (510) and the second blade (520) can be formed with a constant width (W).

[0154] In one embodiment, referring to FIGS. 6 and FIGS. 7a, the first surface (510a) and the second surface (510b) of the first blade (510) may form the end surface of the first blade (510).

The second surface (510b) of the first blade (510) may be formed to face the second surface (520b) of the second blade (520).

[0155] In one embodiment, light entering the lens (411) may include a diffraction phenomenon, which is a phenomenon in which light is refracted and spreads like a wave when passing through a narrow gap. When the incident area of ​​the aperture assembly (500) is adjusted to a minimum open state through the first blade (510) and the second blade (520), a diffraction phenomenon may occur in the first diffraction area (530) and the second diffraction area (540) formed by the first blade (510) and the second blade (520). The first diffraction area (530) and the second diffraction area (540) are formed with a narrow area compared to the second incident area (A2), so that a strong diffraction phenomenon may occur.

[0156] In one embodiment, referring to FIGS. 6 and FIGS. 7a, the second incident region (A2) may include a first diffraction region (530) and a second diffraction region (540).

[0158] In one embodiment, referring to FIG. 7a, a first diffraction region (530) may be formed on one surface (411a) of the lens (411) (e.g., the surface facing the +z axis in FIG. 7a) between the first surface (510a) of the first blade (510) (e.g., the surface facing the +x axis in FIG. 7a) and the first surface (520a) of the second blade (520) (e.g., the surface facing the -x axis in FIG. 7a). A second diffraction region (540) may be formed on one surface (411a) of the lens (411) (e.g., the surface facing the +z axis in FIG. 7a) between the second surface (510b) of the first blade (510) (e.g., the surface facing the +x axis in FIG. 7a) and the second surface (520b) of the second blade (520) (e.g., the surface facing the -x axis in FIG. 7a).

[0159] In one embodiment, referring to FIGS. 6 and FIGS. 7a, the first diffraction region (530) may be arranged symmetrically with respect to the second diffraction region (540) and the optical axis (C) of the lens (411).

[0160] FIGS. 8a and 8b are drawings according to one embodiment of the present disclosure in which a first diffraction region (530) and a second diffraction region (540) are arranged symmetrically with respect to a third straight line (550). FIG. 8c is a drawing according to one embodiment of the present disclosure in which a first diffraction region (530) is arranged on a third straight line (550), and a second diffraction region (541) and a third diffraction region (542) are arranged symmetrically with respect to a third straight line (550).

[0161] In one embodiment, with reference to FIGS. 3, FIGS. 4a, FIGS. 4b, FIGS. 7a, FIGS. 8a, and FIGS. 8b, the first diffraction region (530) and the second diffraction region (540) may be arranged symmetrically with respect to a third line (550) (e.g., a direction substantially parallel to the y-axis in FIG. 8a). The third line (550) may be formed in a direction substantially parallel to the first line (e.g., a direction substantially parallel to the y-axis in FIG. 4a), passing through the optical axis (c) of the lens (411), and substantially perpendicular to the optical axis (c) of the lens (411) (e.g., a direction substantially parallel to the z-axis in FIG. 8a).

[0162] In one embodiment, with reference to FIG. 4a, FIG. 8a, and FIG. 8b, the first diffraction region (530) and the second diffraction region (540) may be arranged symmetrically with respect to the center of each 2PD pixel (602-1, 602-2, 602-3, 602-4) with respect to a first straight line (e.g., a straight line substantially parallel to the y-axis in FIG. 4a) and a third straight line (550) substantially parallel to the first straight line (e.g., a straight line substantially parallel to the y-axis in FIG. 4a) which arranges the light receiving elements (631-1, 632-1, 633-1, 634-1) arranged to the left and the light receiving elements (631-2, 632-2, 633-2, 634-2) arranged to the right. For example, the first diffraction region (530) and the second diffraction region (540) can be arranged symmetrically with respect to the third line (550) of FIG. 8a, which is substantially parallel to the first line that arranges the first-1 light receiving element (631-1) and the first-2 light receiving element (631-2) of the first-2 PD unit pixel (602-1) of FIG. 4a symmetrically. When detecting a horizontal phase difference, the influence caused by the first diffraction region (530) and the second diffraction region (540) may occur symmetrically with respect to the third line (550). For example, since the influence of the first diffraction region (530) and the second diffraction region (540) occurs symmetrically with respect to the third line (550), the comparison value of the electrical data of the first-1 light receiving element (631-1) and the electrical data of the first-2 light receiving element (631-2) can be measured with the influence of the first diffraction region (530) and the second diffraction region (540) minimized.

[0163] In one embodiment, with reference to FIG. 4b, FIG. 8a, and FIG. 8b, the first diffraction region (530) and the second diffraction region (540) are arranged such that the light receiving elements (731-1, 732-1, 733-1, 734-1) positioned in the upper left direction and the light receiving elements (731-2, 732-2, 733-2, 734-2) positioned in the upper right direction are arranged symmetrically with respect to the center of each 4PD pixel (702-1, 702-2, 702-3, 702-4), but the light receiving elements (731-3, 732-3, 733-3, 734-3) positioned in the lower left direction and the light receiving elements positioned in the lower right direction are arranged symmetrically with respect to the center of each 4PD pixel (702-1, 702-2, 702-3, 702-4). The elements (731-4, 732-4, 733-4, 734-4) can be arranged symmetrically with respect to a third line (550) substantially parallel to a first line (e.g., a line substantially parallel to the y-axis in FIG. 4b) that arranges them symmetrically. For example, the first-1 light-receiving element (731-1) and the first-2 light-receiving element (731-2) of the first-4PD pixel (302) in FIG. 4b can be arranged symmetrically, or the first-3 light-receiving element (731-3) and the first-4 light-receiving element (731-4) can be arranged symmetrically with respect to a third line (550) in FIG. 8a that arranges them symmetrically with respect to a first line substantially parallel to a third line (550) that arranges them symmetrically with respect to a first line that arranges them symmetrically with respect to a first line (530) that arranges them symmetrically with respect to a first line (531-4) that arranges them symmetrically with respect to a third line (550) in FIG. 8a. In one embodiment, when detecting a horizontal phase difference, the influence caused by the first diffraction region (530) and the second diffraction region (540) may occur symmetrically with respect to the third straight line (550).For example, since the influence caused by the first diffraction region (530) and the second diffraction region (540) occurs symmetrically with respect to the third straight line (550), the comparison value of the electrical data of the first-1 light receiving element (731-1) and the electrical data of the first-2 light receiving element (731-2), the comparison value of the electrical data of the first-3 light receiving element (731-3) and the electrical data of the first-4 light receiving element (731-4), and the comparison value of the first summed data obtained by summing the electrical data of the first-1 light receiving element (731-1) and the electrical data of the first-3 light receiving element (731-3) and the second summed data obtained by summing the electrical data of the first-2 light receiving element (731-2) and the electrical data of the first-4 light receiving element (731-4) can be measured with the influence caused by the first diffraction region (530) and the second diffraction region (540) minimized. In one embodiment, when detecting a vertical phase difference, the influence caused by the first diffraction region (530) and the second diffraction region (540) may occur symmetrically with respect to the fourth line (570). For example, since the influence caused by the first diffraction region (530) and the second diffraction region (540) occurs symmetrically with respect to the fourth line (570), the comparison value of the electrical data of the first-1 light receiving element (731-1) and the electrical data of the first-2 light receiving element (731-2), the comparison value of the electrical data of the first-3 light receiving element (731-3) and the electrical data of the first-4 light receiving element (731-4), and the comparison value of the first summed data obtained by summing the electrical data of the first-1 light receiving element (731-1) and the electrical data of the first-3 light receiving element (731-3) and the second summed data obtained by summing the electrical data of the first-2 light receiving element (731-2) and the electrical data of the first-4 light receiving element (731-4) can be measured with the influence caused by the first diffraction region (530) and the second diffraction region (540) minimized. there is.

[0164] In one embodiment, referring to FIGS. 8a and 8b, the spacing between the first diffraction region (530) and the second diffraction region (540) can be formed at 180 degrees around the optical axis (C) of the lens (411).

[0165] In one embodiment, with reference to FIG. 8a and FIG. 8b, the first diffraction region (530) and the second diffraction region (540), respectively, may be located between the first surface (510a) of the first blade (510) (e.g., the first end surface of the first blade) and the first surface (520a) of the second blade (520) (e.g., the first end surface of the second blade), and the second surface (510b) of the first blade (510) (e.g., the second end surface of the first blade (510)) and the second surface (520b) of the second blade (520) (e.g., the second end surface of the second blade (520)) where the first blade (510) and the second blade (520) face each other. In one embodiment, the first diffraction region (530) and the second diffraction region (540) may be located on one surface (411a) of the lens (411) between the end of the inner surface (511) of the first blade (510) and the end of the inner surface (521) of the second blade (520).

[0166] In one embodiment, referring to FIGS. 7a and FIGS. 8a, the influence of the first diffraction region (530) and the second diffraction region (540) can be formed at a location that does not impair the electrical data comparison value provided by the data processing unit (e.g., the data processing unit (340) of FIG. 3) in the horizontal direction phase difference detection operation. For example, the first diffraction region (530) and the second diffraction region (540) are arranged symmetrically with respect to the third straight line (550) to cancel out the diffraction phenomenon caused by the first diffraction region (530) and the second diffraction region (540), and are arranged spaced apart from the fourth straight line (570) (e.g., a straight line substantially parallel to the x-axis of FIG. 8a) which is formed in a direction perpendicular to the third straight line (550) that has a significant influence on the horizontal phase difference detection operation, thereby minimizing the influence that the first diffraction region (530) and the second diffraction region (540) provide to the horizontal phase difference detection operation. In one embodiment, on one surface (411a) of the lens (411) between the end of the inner surface (511) of the first blade (510) and the end of the inner surface (521) of the second blade (520), the first diffraction region (530), the second diffraction region (540), and the optical axis (C) of the lens (411) are arranged on a third straight line (550), and the first diffraction region (530) and the second diffraction region (540) may be arranged on one surface (411a) of the lens (411) between the end of the inner surface (511) of the first blade (510) and the end of the inner surface (521) of the second blade (520) by being spaced apart at equal intervals with respect to the optical axis (C) of the lens. In one embodiment, the first diffraction region (530) and the second diffraction region (540) may be disposed on one surface (411a) of the lens (411) between the end of the inner surface (511) of the first blade (510) and the end of the inner surface (521) of the second blade (520), which is 90 degrees away from the point (P1, P2) where the inner surface (511) of the first blade (510) and the inner surface (521) of the second blade (520), respectively, meet the fourth straight line (570).

For example, the first diffraction region (530) and the second diffraction region (540) may be arranged symmetrically with respect to the third straight line (550) to offset the diffraction phenomenon caused by the first diffraction region (530) and the second diffraction region (540), thereby minimizing the influence provided by the first diffraction region (530) and the second diffraction region (540) on the horizontal phase difference detection operation. In one embodiment, on one surface (411a) of the lens (411) between the end of the inner surface (511) of the first blade (510) and the end of the inner surface (521) of the second blade (520), the optical axis (C) of the lens (411) is positioned on a third straight line (550), the first diffraction region (530) and the second diffraction region (540) are positioned on a fourth straight line (570), and the first diffraction region (530) and the second diffraction region (540) may be positioned at equal intervals with respect to the optical axis (C) of the lens. In one embodiment, the first diffraction region (530) and the second diffraction region (540) may be disposed on one surface (411a) of the lens (411) between the end of the inner surface (511) of the first blade (510) and the end of the inner surface (521) of the second blade (520), which is 90 degrees away from the point (P3, P4) where the inner surface (511) of the first blade (510) and the inner surface (521) of the second blade (520) respectively meet the third straight line (550).

[0169] The aperture assembly (500-2) of FIG. 8c may be at least partially similar to the aperture assembly (500) of FIG. 7a through FIG. 8a, or may include other embodiments of the aperture assembly (500).

The inner surface (511) of the first blade (510), the inner surface (521) of the second blade (520), and the inner surface (561) of the third blade (560) may form the second incident region (A2).

[0173] In one embodiment, referring to FIG. 8c, the second incident region (A2) may include a first diffraction region (530), a second diffraction region (541), and a third diffraction region (542).

In one embodiment, the first diffraction region (530), the second diffraction region (541), and the third diffraction region (542) may each be located on one surface (411a) of the lens (411) between the end of the inner surface (511) of the first blade (510), the end of the inner surface (521) of the second blade (520), and the end of the inner surface (561) of the third blade (560).

[0177] In one embodiment, referring to FIG. 8c, the influence of the first diffraction region (530), the second diffraction region (541), and the third diffraction region (542) can be formed at a location that does not impair the electrical data comparison value provided by the data processing unit (e.g., the data processing unit (340) of FIG. 3) in the horizontal direction phase difference detection operation. For example, the first diffraction region (530), the second diffraction region (541), and the third diffraction region (542) are spaced apart from the fourth straight line (570), which has a significant influence on the horizontal phase difference detection operation, and the second diffraction region (541) and the third diffraction region (542) are symmetrically arranged with respect to the third straight line (550) to offset the diffraction phenomenon caused by the second diffraction region (541) and the third diffraction region (542), thereby minimizing the influence provided by the first diffraction region (530), the second diffraction region (541), and the third diffraction region (542) on the horizontal phase difference detection operation. In one embodiment, on one surface (411a) of the lens (411), the first diffraction region (530) is positioned on a third straight line (550) between the end of the inner surface (511) of the first blade (510) and the end of the inner surface (521) of the second blade (520), and the second diffraction region (541) and the third diffraction region (542), respectively, are positioned 60 degrees around the optical axis (C) of the lens from the point (P5, P6) where the inner surface (511) of the first blade (510) and the inner surface (521) of the second blade (520), respectively, meet the fourth straight line (570), and are positioned between the end of the inner surface (511) of the first blade (510) and the end of the inner surface (561) of the third blade (560), and between the end of the inner surface (521) of the second blade (520) and the third blade (560).

[0179] In one embodiment, with reference to FIG. 4a and FIG. 8c, two of the first diffraction region (530), the second diffraction region (541), and the third diffraction region (542) are symmetrically positioned with respect to the center of each 2PD pixel (602-1, 602-2, 602-3, 602-4) with respect to a first straight line (e.g., a direction substantially parallel to the y-axis in FIG. 4a) and a third straight line (550) substantially parallel to the first straight line (e.g., a direction substantially parallel to the y-axis in FIG. 4a) which symmetrically positions the light receiving elements (631-1, 632-1, 633-1, 634-1) positioned to the left and the light receiving elements (631-2, 632-2, 633-2, 634-2) positioned to the right, and the remaining one diffraction region can be positioned with respect to the third straight line (550). For example, the second diffraction region (541) and the third diffraction region (542) may be arranged symmetrically with respect to the third line (550) of FIG. 8c, which is substantially parallel to the first line that arranges the first-1 light receiving element (631-1) and the first-2 light receiving element (631-2) of the first-2 PD unit pixel (602-1) of FIG. 4a symmetrically, and the first diffraction region (530) may be arranged on the third line (550).

For example, the first diffraction region (530) and the second diffraction region (541) may be spaced 150 degrees around the optical axis (C) of the lens (411), the second diffraction region (541) and the third diffraction region (542) may be spaced 60 degrees around the optical axis (C) of the lens (411), and the third diffraction region (542) and the first diffraction region (530) may be spaced 150 degrees around the optical axis (C) of the lens (411) and may be placed on one surface (411a) of the lens (411) that is furthest from the optical axis (C) of the lens (411) and the fourth line (570).In one embodiment, when detecting a horizontal phase difference, the influence caused by the first diffraction region (530), the second diffraction region (541), and the third diffraction region (542) may occur symmetrically with respect to the third straight line (550). For example, since the influence caused by the first diffraction region (530), the second diffraction region (541), and the third diffraction region (542) occurs symmetrically with respect to the third straight line (550), the comparison value of the electrical data of the first-1 light receiving element (631-1) and the electrical data of the first-2 light receiving element (631-2) can be measured with the influence caused by the first diffraction region (530), the second diffraction region (541), and the third diffraction region (542) minimized.

In one embodiment, the first diffraction region (530), the second diffraction region (541), and the third diffraction region (542) may be spaced apart from a fourth straight line (570) (e.g., a straight line substantially parallel to the x-axis of FIG. 8c) which passes through the optical axis (c) of the lens (411) and is formed in a direction perpendicular to the third straight line (550).For example, the first diffraction region (530) and the second diffraction region (541) may be spaced 150 degrees around the optical axis (C) of the lens (411), the second diffraction region (541) and the third diffraction region (542) may be spaced 60 degrees around the optical axis (C) of the lens (411), and the third diffraction region (542) and the first diffraction region (530) may be spaced 150 degrees around the optical axis (C) of the lens (411), and may be placed on one surface (411a) of the lens (411) furthest from the optical axis (C) of the lens (411) and the fourth straight line (570). When detecting a horizontal phase difference, the influence caused by the first diffraction region (530) and the second diffraction region (541), and the influence caused by the third diffraction region (542), may occur symmetrically with respect to the third straight line (550). For example, since the influence caused by the first diffraction region (530) and the second diffraction region (541), and the influence caused by the third diffraction region (542), occur symmetrically with respect to the third straight line (550), the comparison value of the electrical data of the first-1 light receiving element (731-1) and the electrical data of the first-2 light receiving element (731-2), the comparison value of the electrical data of the first-3 light receiving element (731-3) and the electrical data of the first-4 light receiving element (731-4), and the comparison value of the first summed data obtained by summing the electrical data of the first-1 light receiving element (731-1) and the electrical data of the first-3 light receiving element (731-3) and the second summed data obtained by summing the electrical data of the first-2 light receiving element (731-2) and the electrical data of the first-4 light receiving element (731-4) are the first diffraction region (530), the second diffraction The influence of the region (541) and the third diffraction region (542) can be minimized and measured.
