The memory (250) can temporarily store at least a portion of an image acquired through the image sensor (230) for the next image processing task. For example, when image acquisition is delayed due to a shutter, or when 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 the memory (250), and a corresponding copy image (e.g., a low-resolution image) can be previewed through the display module (160). Thereafter, when a specified condition is satisfied (e.g., a user input or a system command), at least a portion of the original image stored in the memory (250) can be acquired and processed, for example, by an image signal processor (260). According to one or more embodiments, the memory (250) may be configured as at least a portion of the memory (130), or as a separate memory that operates independently therefrom.

The one or more image processing operations 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 softening). Additionally or alternatively, the image signal processor (260) may perform control (e.g., exposure time control, read-out timing control, etc.) on at least one of the components included in the camera module (180) (e.g., image sensor (230)). The image processed by the image signal processor (260) may be stored back in the memory (250) for further processing or provided to an external component of the camera module (180) (e.g., memory (130), display module (160), electronic device (102), electronic device (104), or server (108)). According to one or more embodiments, the image signal processor (260) may be configured to perform a control operation on the processor (120). It may be configured as a separate processor that is at least partially composed of, or 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) by the processor (120) as is or after undergoing additional image processing.

A suction center (SC) on which the suction resultant force (Fn) acts may be offset from the optical axis (A) and may be located within a virtual shape (P) (e.g., a triangle) which may be referred to as a “virtual support surface” connecting the first ball (B1) and the plurality of second balls (B2). The virtual shape (P) may intersect at least a portion of the lens (411). This can reduce the distance between the center of gravity and the center of attraction (SC) of the carrier (441), and reduce the shaking (e.g., tilting) of the carrier (441) in a direction different from the direction along the optical axis (A) when the carrier (441) is driven in a direction along the optical axis (A) (e.g., the Z-axis direction).

[0100] The camera module (400) may include a third ball (B3). The third ball (B3) may be positioned on the first guide (G11) and the third guide (G21). The third ball (B3) may be sized to define a desired operating distance of the first ball (B1). For example, the size of the third ball (B3) may be substantially the same as or smaller than the size of the first ball (B1).

[0101] The camera module (400) may include a fourth ball (B4). The fourth ball (B4) may be disposed on the second guide (G21) and the fourth guide (G22). The fourth ball (B4) may be disposed between adjacent second balls (B2) to define a gap between the plurality of second balls (B2). The fourth ball (B4) may increase the gap between the second balls (B2), thereby increasing the size of the virtual shape (P) connecting the first ball (B1) and the plurality of second balls (B2), and reducing the possibility of shaking (e.g., tilting) of the carrier (441). For example, the size of the fourth ball (B4) may be substantially the same as or smaller than the size of the second ball (B2).

[0102] The camera module (400) may include a plurality of dampers (460) configured to damp movement of the carrier (441) in a direction along the optical axis (A) with respect to the base frame (421) (e.g., in the Z-axis direction). The plurality of dampers (460) may include a viscoelastic material. For example, the plurality of dampers (460) may include a high-viscosity gel-like elastomer material. The plurality of dampers (460) may be arranged in a plurality of clearance spaces between the base frame (421) and the carrier (441). For example, the plurality of dampers (460) may be arranged between clearance spaces around the first guide (G11) and the third guide (G21) and clearance spaces around the second guide (G12) and the fourth guide (G22).

[0103] A plurality of dampers (460) may be arranged close to the virtual shape (P). For example, the plurality of dampers (460) may be arranged in a clearance space between the base frame (421) and the carrier (441) between the virtual shape (P) and a first virtual contact surface (V1) that is substantially parallel to the virtual shape (P) and contacts the lens housing (412). The plurality of dampers (460) may be arranged in a clearance space between the base frame (421) and the carrier (441) between the virtual shape (P) and a second virtual contact surface (V2) that is opposite to the first virtual contact surface (V1) with respect to the virtual shape (P) and is substantially parallel to the virtual shape (P) and contacts the lens housing (412). A structure in which a plurality of dampers (460) are arranged close to a virtual shape (P) can reduce or prevent tilting of the lens (411) due to the plurality of dampers (460).

[0104] A plurality of dampers (460) can be arranged substantially symmetrically with respect to a virtual shape (P). This can reduce or prevent tilting of the lens (411) due to the plurality of dampers (460).

[0105] The camera module (400) may include a flexible printed circuit board (470). The flexible printed circuit board (470) may at least partially surround a side of the base frame (421). The flexible printed circuit board (470) may include a first substrate area (470A) disposed on a first side wall (421B), and a second substrate area (470B) facing a third side wall (421D). A first coil (443A), a sensor (444), and a metal piece (445) may be disposed on the first substrate area (470A), and a second coil (443B) may be disposed on the second substrate area (470B). The first coil (443A) may be electrically connected to the first substrate area (470A), and the second coil (443B) may be electrically connected to the second substrate area (470B).

It may include an actuator (440-2)).

[0114] The camera housing (420-3) may include a base frame (421-3) (e.g., the base frame (421) of FIGS. 5 to 10 and / or the base frame (421) of FIG. 11). The base frame (421-3) may include a first side wall (421B), a second side wall (421C), a third side wall (421D), and a fourth side wall (421E). The base frame (421-3) may include a first guide (G11) disposed inside the fourth side wall (421E) and open toward the first side wall (421B) and the third side wall (421D), and a second guide (G12) disposed inside the third side wall (421D) and open toward the second side wall (421C) and the fourth side wall (421E).

[0115] The actuator (440-3) may include a carrier (441-3) (e.g., the carrier (441) of FIGS. 5-10, the carrier (441) of FIG. 11, and / or the carrier (441) of FIG. 12). The carrier (441-3) may include a first outer side carrier face (441C), a second outer side carrier face (441D), a third outer side carrier face (441E), and a fourth outer side carrier face (441F). The carrier (441-3) may include a third guide (G21) disposed in a corner region between the first outer side carrier face (441C) and the fourth outer side carrier face (441F) and open toward the fourth side wall (421E), and a fourth guide (G22) disposed in a corner region between the second outer side carrier face (441D) and the third outer side carrier face (441E) and open toward the third side wall (421D). The carrier (441-3) may include a first recess (R1) recessed in the first outer side carrier face (441C), and a second recess (R2) recessed in the third outer side carrier face (441E).
