Title: Camera module

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit under 35 USC 119(a) of Korean Patent Application No. 10-2021-01 60535 filed on Nov. 19, 2021, in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference for all purposes. 
     BACKGROUND 
     1. Field 
     The present disclosure relates to a camera module. 
     2. Description of the Background 
     Camera modules may be employed in portable electronic devices including smartphones. Portable electronic devices may tend to be decreased in thickness (thinned) due to market demand, and accordingly, the miniaturization of camera modules may be required. 
     In particular, in order to prevent a height of the camera module from greatly affecting a thickness of the portable electronic device, a camera module having a reflective member for altering a path of light has been proposed. 
     Since the camera module alters the path of light through the reflective member, a total track length (a distance from a lens closest to an object side to the imaging surface of the image sensor) of the camera module may not affect the thickness of the portable electronic device. 
     In addition, a camera module employing a plurality of reflective members has been proposed to improve a problem that the total track length of the camera module may be too large in one direction. 
     However, in this case, since the optical path is formed to be elongated by the plurality of reflective members, the light may be reflected by an internal structure of the camera module before light is incident on the image sensor, and this diffusely reflected light may be incident on the image sensor and a flare phenomenon may occur. 
     The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

     Throughout the drawings and the detailed description, the same reference numerals refer to the same elements. The drawings may not be to scale, and the relative sizes, proportions, and depictions of elements in the drawings may be exaggerated for clarity, illustration, and convenience. 
     DETAILED DESCRIPTION 
     Hereinafter, while example embodiments of the present disclosure are described in detail with reference to the accompanying illustrative drawings, it is noted that examples are not limited to the same. 
     In addition, the same reference numerals as used in the accompanying drawings denote parts or components performing substantially the same function. For ease of explanation and understanding, different embodiments will be described using the same reference numerals. In other words, even though all the elements having the same reference numerals are shown in the plural drawings, the plural drawings do not mean one embodiment. 
     The following detailed description is provided to assist the reader in gaining a comprehensive understanding of the methods, apparatuses, and/or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatuses, and/or systems described herein will be apparent after an understanding of this disclosure. For example, the sequences of operations described herein are merely examples, and are not limited to those set forth herein, but may be changed as will be apparent after an understanding of this disclosure, with the exception of operations necessarily occurring in a certain order. Also, descriptions of features that are known in the art may be omitted for increased clarity and conciseness. 
     The features described herein may be embodied in different forms, and are not to be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many possible ways of implementing the methods, apparatuses, and/or systems described herein that will be apparent after an understanding of this disclosure. 
     In the present document, the X-direction, Y-direction, and Z-direction refer to a direction parallel to the X-axis, a direction parallel to the Y-axis, and a direction parallel to the Z-axis shown in the drawings, respectively. In addition, unless otherwise described, the X-direction is a concept including both the +X-axis direction and the -X-axis direction, which also applies to the Y-direction and the Z-direction. 
     When two directions (or axes) are described as parallel to or perpendicular to each other in the present disclosure, this also includes cases in which the two directions (or axes) are substantially parallel or substantially parallel to each other. For example, when a first axis and a second axis are perpendicular to each other, the first axis and the second axis form an angle of 90 degrees or close to 90 degrees. 
     Throughout the specification, when an element, such as a layer, region, or substrate is described as being “on,” “connected to,” or “coupled to” another element, it may be directly “on,” “connected to,” or “coupled to” the other element, or there may be one or more other elements intervening therebetween. In contrast, when an element is described as being “directly on,” “directly connected to,” or “directly coupled to” another element, there can be no other elements intervening therebetween. 
     As used herein, the term “and/or” includes any one and any combination of any two or more of the associated listed items; likewise, “at least one of” includes any one and any combination of any two or more of the associated listed items. 
     Although terms such as “first,” “second,” and “third” may be used herein to describe various members, components, regions, layers, or sections, these members, components, regions, layers, or sections are not to be limited by these terms. Rather, these terms are only used to distinguish one member, component, region, layer, or section from another member, component, region, layer, or section. Thus, a first member, component, region, layer, or section referred to in examples described herein may also be referred to as a second member, component, region, layer, or section without departing from the teachings of the examples. 
     Spatially relative terms, such as “above,” “upper,” “below,” “lower,” and the like, may be used herein for ease of description to describe one element&#39;s relationship to another element as shown in the figures. Such spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, an element described as being “above,” or “upper” relative to another element would then be “below,” or “lower” relative to the other element. Thus, the term “above” encompasses both the above and below orientations depending on the spatial orientation of the device. The device may also be oriented in other ways (rotated 90 degrees or at other orientations), and the spatially relative terms used herein are to be interpreted accordingly. 
     The terminology used herein is for describing various examples only, and is not to be used to limit the disclosure. The articles “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “includes,” and “has” specify the presence of stated features, numbers, operations, members, elements, and/or combinations thereof, but do not preclude the presence or addition of one or more other features, numbers, operations, members, elements, and/or combinations thereof. 
     Due to manufacturing techniques and/or tolerances, variations of the shapes shown in the drawings may occur. Thus, the examples described herein are not limited to the specific shapes shown in the drawings, but include changes in shape that occur during manufacturing. 
     Herein, it is noted that use of the term “may” with respect to an example, for example, as to what an example may include or implement, means that at least one example exists in which such a feature is included or implemented while all examples are not limited thereto. 
     The features of the examples described herein may be combined in various ways as will be apparent after an understanding of this disclosure. Further, although the examples described herein have a variety of configurations, other configurations are possible as will be apparent after an understanding of this disclosure. 
     An aspect of the present disclosure is to provide a camera module capable of preventing a flare phenomenon. 
       FIG.  1    is a perspective view of a portable electronic device on which a camera module according to one or more embodiments of the present disclosure is mounted, and  FIG.  2    is a schematic perspective view of the camera module shown in  FIG.  1   . 
     Referring to  FIGS.  1  and  2   , a camera module  1000  according to an embodiment of the present disclosure may be mounted on a portable electronic device  1 . The portable electronic device  1  may be a portable electronic device such as a mobile communication terminal, a smartphone, a table PC, or the like. 
     As illustrated in  FIG.  1   , the camera module  1000  is mounted on the portable electronic device  1  to image a subject. 
     In the present embodiment, the camera module  1000  includes a plurality of lenses, and an optical axis (a Z-axis) of the lens may be directed in a direction, perpendicular to a thickness direction (a Y-axis direction, a direction from a front surface of the portable electronic device toward a rear surface thereof or vice versa) of the portable electronic device. 
     For example, the optical axis (the Z-axis) of the plurality of lenses provided in the camera module  1000  may be formed in the width direction or the length direction of the portable electronic device  1 . 
     Therefore, even if functions such as autofocusing (hereinafter, referred to as AF), optical zoom (hereinafter, referred to as zoom) and optical image stabilizing (hereinafter, referred to as OIS), or the like, are provided in the portable electronic device  1 , it is possible to prevent the thickness of the portable electronic device  1  from increasing. Accordingly, the portable electronic device  1  may be thinned. 
     The camera module  1000  according to an embodiment of the present disclosure may be provided with at least one of AF, zoom, and OIS functions. 
     Since the camera module  1000  including AF, zoom, OIS functions, and the like, needs to be provided with various parts, the size of the camera module may be increased as compared to the general camera module. 
     When the size of the camera module  1000  increases, it may be difficult to reduce the thickness of the portable electronic device  1  on which the camera module  1000  is mounted. 
     For example, the camera module may include a plurality of lens groups for the zoom function. When the plurality of lens groups are disposed in the thickness direction of the portable electronic device, the thickness of the portable electronic device also increases according to the number of lens groups. Accordingly, if the thickness of the portable electronic device is not increased, the number of lens groups cannot be sufficiently secured, and thus zoom performance may be weakened. 
     In addition, to implement the AF, zoom, and OIS functions, an actuator moving a plurality of lens groups in the optical axis direction or a direction, perpendicular to the optical axis should be installed. When the optical axis (the Z-axis) of the lens group is formed in the thickness direction of the portable electronic device, an actuator for moving the lens group should also be installed in the thickness direction of the portable electronic device. Therefore, the thickness of the portable electronic device is increased. 
     However, since in the camera module  1000  according to an embodiment of the present disclosure, the optical axes (the Z-axis) of the plurality of lenses are disposed to be perpendicular to the thickness direction of the portable electronic device  1 , even if the camera module  1000  provided with the AF, zoom, and OIS functions is mounted thereon, the portable electronic device  1  can be thinned. 
       FIG.  3    is a schematic exploded perspective view of the camera module shown in  FIG.  2   . In addition,  FIG.  4    is a partial perspective view of the camera module shown in  FIG.  2   , with a case and a circuit board omitted from the illustration for convenience of understanding. 
     Referring to  FIGS.  3  and  4   , a camera module  1000  may include a housing  100 , a reflective module  300 , a lens module  400 , an image sensor module  500 , and a case  200 . 
     A reflective module  300 , a lens module  400 , and an image sensor module  500  may be disposed inside the housing  100  from one side to the other side. The housing  100  may have an inner space to accommodate the reflective module  300 , the lens module  400 , and the image sensor module  500 . However, the image sensor module  500  may be attached to an outside of the housing  100 . 
     In  FIGS.  2  and  3   , an embodiment in which the reflective module  300 , the lens module  400 , and the image sensor module  500  are disposed inside the housing  100  is illustrated. However, unlike the embodiments of  FIGS.  2  and  3   , the reflective module  300  may be disposed outside the housing  100 , and in this case, one side of the housing  100  may be opened so that the light transmitted from the reflective module  300  passes therethrough. 
     The housing  100  may have a box shape having an open upper portion. 
     A protruding wall may be provided inside the housing. The protruding wall may be formed to protrude from a sidewall of the housing toward the inner space. A blocking portion having a window, which will be described later, is coupled to the protruding wall. Accordingly, the protruding wall may be disposed inside the housing, and may be disposed within a range that does not block the window of the blocking portion. 
     The case  200  is coupled to the housing  100  so as to cover an upper portion of the housing  100 . The case  200  may have an opening  210  through which light is incident. The light incident through the opening  210  of the case  200  may be incident on a lens module  400  by altering a traveling direction by a reflective module  300 . 
     The reflective module  300  may be configured to alter a traveling direction of light. For example, a traveling direction of the light incident into the housing  100  may be changed toward the lens module  400  through the reflective module  300 . Therefore, based on an optical path, the reflective module  300  may be disposed in front of the lens module  400 . 
     The reflective module  300  includes a reflective member  310  and a holder  330  on which the reflective member  310  is mounted. 
     The reflective member  310  is configured to change a traveling direction of light. For example, the reflective member  310  may be a mirror or a prism reflecting light. 
     The lens module  400  may include a plurality of lenses through which the light whose traveling direction is changed by the reflective member  310  passes, and a lens barrel  410  accommodating the plurality of lenses. 
     For convenience of explanation, only the lens L 1  disposed closest to an object side among the plurality of lenses is illustrated in  FIG.  3   , but the present disclosure is not limited thereto. 
     The image sensor module  500  may include a sensor housing  510 , an infrared cut-off filter  530 , an image sensor  550 , and a circuit board  570 . 
     An infrared cut-off filter  530  may be mounted on the sensor housing  510 . The infrared cut-off filter  530  serves to block light in an infrared region among the light passing through the lens module  400 . 
     The circuit board  570  may be coupled to the sensor housing  510 , and the image sensor  550  may be mounted on one surface thereof. 
     Accordingly, the light passing through the lens module  400  may pass through the infrared cut-off filter  530  to be received by the image sensor  550 . 
     The reflective module  300 , the lens module  400 , and the image sensor module  500  according to the present embodiment may be disposed in an optical axis direction (Z-axis direction), and the light whose traveling direction is changed by the reflective module  300  may be incident on the image sensor  550  through the lens module  400 . 
     However, if unintentional reflection occurs before the light is incident on the image sensor  550 , a flare phenomenon may occur therefrom. For example, before the light passing through the lens module  400  reaches the image sensor  550 , when the light reflected from a bottom surface of the housing  100  or an inner surface of the case  200  (a surface facing the bottom surface of the housing  100 ) is incident on the image sensor  550 , a flare phenomenon may occur. 
     As such, a flare phenomenon may occur due to internal reflection occurring in the space between the lens module  400  and the image sensor  550 . 
     Accordingly, the camera module  1000  according to the present embodiment may include a light shielding member  600  to prevent a flare phenomenon due to unintentional reflection of light. 
       FIG.  5    is an enlarged perspective view of the light shielding member shown in  FIG.  3   , and  FIG.  6    is a cross-sectional view taken along line I-I′ of  FIG.  4   . 
     Referring to  FIGS.  5  and  6    together, a light shielding member  600  may be disposed in a space between the lens module  400  and the image sensor module  500 . For example, the light shielding member  600  may be disposed in a space between a lens, closest to the image sensor module among a plurality of lenses provided in the lens module  400  and the image sensor module  500 . 
     Accordingly, when unintentional reflection of light occurs between the lens module  400  and the image sensor module  500 , the light shielding member  600  may block the reflected light from flowing into the image senor. 
     Accordingly, it is possible to prevent unnecessary light from being incident on the image sensor  550 , and thus, it is possible to suppress an occurrence of a flare phenomenon due to the reflection of the light. 
     The light shielding member  600  of the present embodiment may include a frame  610  and a damping member  620 . 
     The frame  610  may have a rectangular shape having a long side and a short side, and may include a light shielding portion  612  and a fixing portion  615 . 
     The light shielding portion  612  may include an opening-shaped window W therein. The window W may pass light through the lens module  400  to be incident on the image sensor  550 . Accordingly, light used for image formation may pass through the window W and may be incident on the image sensor  550 , and light that may cause a flare phenomenon may be blocked by the frame  610 . 
     The fixing portion  615  may be disposed on both ends of the frame  610  to be fixedly coupled to the housing  100 . Specifically, the fixing portion  615  may be respectively coupled to the protruding wall  105  of the housing  100  described above. 
     In addition, the light shielding member  600  of the present embodiment may function as a stopper for limiting movement of the lens module  400 . Accordingly, when the lens module  400  moves toward the image sensor module  500  as much as possible, the lens module  400  comes into contact with the light shielding member  600 , and thus movement toward the image sensor module  500  may be limited. 
     As the lens module  400  repeatedly contacts the light shielding member  600 , an impact according to the contact may be repeatedly generated between the light shielding member  600  and the lens module  400 . Accordingly, the light shielding member  600  must be stably fixed to the protruding wall  105  even when the above-described impact is repeatedly generated. To this end, the fixing portion  615  of the present embodiment may contact at least three surfaces of the protruding wall  105  and be coupled to the protruding wall  105 . 
     As illustrated in  FIGS.  4  and  6   , the fixing portion  615  may be coupled to the protruding wall  105  in a form surrounding two surfaces of the protruding wall  105 , disposed to be perpendicular to an optical axis direction, and an upper surface of the protruding wall  105 . However, the configuration of the present disclosure is not limited thereto, and it is also possible to configure the fixing portion  615  to contact only one or two surfaces of the protruding wall  105 . In addition, the fixing portion  615  may be bonded to the protruding wall  105  through an adhesive or may be fastened to the protruding wall  105  through a separate fastening member. 
     In the present embodiment, a frame  610  may be formed of a metal material. However, the configuration of the present disclosure is not limited thereto, and various modifications are possible as needed, such as forming the frame  610  of a resin material or an inorganic material. 
     A blocking film for blocking movement of light by scattering light may be provided on a surface of the frame  610 . The blocking film may be formed to increase surface roughness of the frame  610  by performing surface treatment of the frame  610 . Accordingly, light incident on the surface of the frame  610  may be diffusely reflected by the blocking film and may be extinguished or may be blocked from proceeding. 
     In the present embodiment, the surface of the blocking film may be formed to be rougher than a surface of the housing  100 , and to this end, a surface of the frame  610  may be corroded. 
     However, an example embodiment of the present inventive concept is not limited thereto, and it is also possible to separately manufacture a blocking film in a form in a thin film and then attach the same to the surface of the frame  610 . 
     In addition, a light absorption layer  617  blocking unnecessary light may be provided on the surface of the frame  610 . The light absorption layer  617  may be provided to lower reflectance of the surface of the frame  610 , and may be formed in black. 
     The light absorption layer  617  may be provided by forming a black oxide film on the surface of the frame  610 . However, an embodiment of the present disclosure is not limited thereto, and as long as the surface of the frame  610  can be formed in black, various methods can be used. For example, the light absorption layer  617  in a form of a thin film may be manufactured and attached to the surface of the frame  610 . In this case, after carbon coating a film made of a resin material such as Polyethylene Terephthalate (PET), it may be attached to the frame  610  to be used as the light absorption layer  617 . It is also possible to form the light absorption layer  617  by directly applying a black paint to the surface of the frame  610 . 
     In the present embodiment, a case in which a blocking film and a light absorption layer  617  are formed in the same region will be described as an example. In this case, the light absorption layer  617  may be formed by coloring a surface of the blocking film, or a blocking film may be formed by increasing the surface roughness of the light absorption layer  617 . 
     The blocking film or the light absorption layer  617  may be formed on at least one of both surfaces of the frame  610 . In addition, the blocking film and the light absorption layer  617  may be formed only on a portion of the surface of the frame  610 . However, an example embodiment of the present inventive concept is not limited thereto, and it is also possible to form a blocking film or a light absorption layer  617  on the entirety of one or both surfaces of the frame  610 . 
     When the blocking film or the light absorption layer  617  is formed only on a partial region of the frame  610 , the blocking film or the light absorption layer  617  may be concentrated around a window W as shown in  FIG.  5   . For example, the blocking film or the light absorption layer  617  may be disposed only on the light shielding portion  612 . However, an embodiment of the present disclosure is not limited thereto. 
     Also, as an embodiment, it may be deformed into various shapes as needed, such as forming a blocking film on some regions on a surface of the frame  610 , forming a light absorption layer  617  on other regions, and the like. For example, the blocking film may be formed on the entire surface of the frame  610 , and the light absorption layer  617  may be formed only on the light shielding portion  612 . 
     As described above, the light shielding member  600  of the present embodiment may function as a stopper of the lens module  400 . Accordingly, when the lens module  400  moves toward the image sensor module  500  as far as possible, the lens module  400  may contact the light shielding member  600 . In this process, in order to minimize the impact applied to the light shielding member  600  or the lens module  400 , the light shielding member  600  may be provided with a damping member  620 . 
     The damping member  620  may be disposed on the fixing portion  615 , and may be disposed on one surface facing the lens module  400  among both surfaces of the frame  610 . A plurality of damping members  620  may be dispersedly disposed around the window W, and in the present embodiment, the two damping members  620  are disposed in the fixing portions  615  on both sides of the window W, respectively. 
     Since an impact is repeatedly applied to the damping member  620 , a portion corresponding to the damping member  620  on the other surface of the frame  610  needs to be firmly supported. Accordingly, the camera module of the present embodiment may be supported by the fixing portion  615  and the entirety thereof may be supported by the protruding wall  105 . 
     More specifically, the damping member  620  may be disposed in a region corresponding to the protruding wall  105  on one surface of the frame  610 . Here, the region corresponding to the protruding wall  105  refers to a region in which a projected shape of the damping member  620  is disposed, when the protruding wall  105  is projected onto one surface of the frame  610 . Accordingly, at least a portion of the fixing portion  615  may be disposed between the damping member  620  and the protruding wall  105 . 
     The damping member  620  may be formed of a material having elasticity to absorb impacts. For example, the damping member  620  may be formed of any one of urethane, rubber, and silicone, but an example embodiment thereof is not limited thereto. 
     The camera module of the present embodiment configured as described above may provide a function of a stopper of the lens module  400  as well as shielding unnecessary light by the light shielding member  600 . Therefore, there is no need to separately provide a member serving as a stopper of the lens module  400 , and a process of installing such a member in the housing  100  can be omitted. 
     Accordingly, manufacturing costs can be reduced, and manufacturing processes can also be simplified. In addition, since elements disposed inside the housing  100  can be reduced, an overall volume of the camera module can be minimized. 
     However, the camera module of the present disclosure is not limited to the above-described embodiments, and various modifications may be performed. 
       FIG.  7    is a schematic exploded perspective view of a camera module according to one or more other embodiments of the present disclosure,  FIG.  8    is a partial perspective view of the camera module shown in  FIG.  7   , and for convenience of understanding, a case and a circuit board are omitted from the illustration in  FIG.  8   . Also,  FIG.  9    is an enlarged perspective view of the light shielding member  600   a  shown in  FIG.  7   . 
     Referring to  FIGS.  7  to  9   , in the camera module of the present embodiment, a light shielding portion  612  may be disposed at a position, close to the image senor module  500 . Moreover, the light shielding portion  612  may be disposed on a different plane from a fixing portion  615 . Here, the fixing portion  615  refers to a portion disposed between a damping member  620  of the fixing portion  615  and the protruding wall  105 , rather than the entire region of the fixing portion  615 . 
     To this end, a connection portion  616  may be formed between the light shielding portion  612  and the fixing portion  615 . The connection portion  616  is a portion connecting the light shielding portion  612  and the fixing portion  615 , and may be formed by bending a frame  610  through press working, or the like. Accordingly, a distance between the light shielding portion  612  and the fixing portion  615  may be defined according to the size of the connection portion  616 . 
     The connection portion  616  may be disposed to surround the other surface of the protruding wall  105 . Accordingly, the fixing portion  615  and the connection portion  616  may be configured to surround four surfaces of the protruding wall  105  and be fixed to the protruding wall  105 . In addition, at least a portion of the connection portion  616  may be disposed to face the protruding wall  105 . Specifically, at least a portion of the connection portion  616  may be disposed in parallel with one surface of the protruding wall  105 , and may be disposed in adjacent to the one surface or disposed to be very adjacent to the one surface. Here, one surface of the protruding wall  105  may refer to a surface disposed parallel to an optical axis direction. 
     When the fixing portion  615  and the light shielding portion  612  are configured to be disposed on the same plane as in the above-described embodiment, a distance between the light shielding member  600  and the image sensor module  500  may be excessively spaced apart. In this case, diffuse reflection of light may occur in the space between the light shielding member  600  and the image sensor module  500 , which may cause a flare phenomenon. 
     However, when the light shielding member  600  of the present embodiment is used, since the light shielding portion  612  is disposed close to the image sensor module  500 , the above-described problem can be minimized. 
     As set forth above, according to an embodiment of the present disclosure, a camera module may prevent a flare phenomenon.
