Abstract
Description
Technical Field
[0001] This disclosure relates to multiple cameras and electronic devices including such cameras. Background Technology
[0002] Smartphones or electronic devices such as tablet PCs may include cameras (or camera modules or camera devices) and can take photos or videos.
[0003] Currently, with the expansion of the effective area of displays, full-frontal displays are emerging that realize a large portion of one surface (e.g., the front surface) of an electronic device as the effective area of the display. In this case, a camera module in the first surface (e.g., the front surface) can be arranged below the display panel (under display camera, UDC). The electronic device can acquire image data using light passing through the display panel and the lens of the camera module.
[0004] The above information is presented as background information only to aid in understanding this disclosure. No determination or assertion is made regarding whether any of the above can be applied to this disclosure as prior art. Summary of the Invention
[0005] [Technical Issues]
[0006] When electronic devices include a down-display camera (UDC), image quality degradation can occur due to the characteristics of the pattern in the display panel. For example, diffraction or scattering of light caused by the pattern in the display panel may cause attenuation of components in certain frequency bands, which can lead to reduced resolution. Alternatively, when photographing a light source, light flares as light bursts may be lost. Electronic devices can compensate for the image quality of the down-display camera (UDC) using software methods such as signal processing or deep learning. In this case, when the signal attenuation is high, it may be difficult to recover the lost frequency components, and the degradation in image quality may not be fully compensated.

[0054] The reference is to the block diagram 200. Figure 2 Camera module 180 may include lens assembly 210, flash 220, image sensor 230, image stabilizer 240, memory 250 (e.g., buffer memory), or image signal processor 260. Lens assembly 210 may collect light emitted or reflected from an object from which an image is to be captured. Lens assembly 210 may include one or more lenses. According to embodiments, camera module 180 may include multiple lens assemblies 210. In this case, camera module 180 may form, for example, a dual-camera, a 360-degree camera, or a spherical camera. Some of the multiple 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 another lens assembly. Lens assembly 210 may include, for example, a wide-angle lens or a telephoto lens.
[0055] Flash 220 can emit light to enhance light reflected from an object. According to embodiments, flash 220 may include one or more light-emitting diodes (LEDs) (e.g., red-green-blue (RGB) LEDs, white LEDs, infrared (IR) LEDs, or ultraviolet (UV) LEDs) or xenon lamps. Image sensor 230 can obtain an image corresponding to an object by converting light emitted or reflected from the object and transmitted via lens assembly 210 into an electrical signal. According to embodiments, image sensor 230 may include one selected from image sensors with different properties, such as an RGB sensor, a black-and-white (BW) sensor, an IR sensor, or a UV sensor, multiple image sensors having the same properties, or multiple image sensors with different properties.

According to embodiments, image stabilizer 240 can use a gyroscope sensor (not shown) or accelerometer sensor (not shown) disposed inside or outside camera module 180 to sense such movement of camera module 180 or electronics 101. According to embodiments, image stabilizer 240 can be implemented as, for example, an optical image stabilizer. Memory 250 can at least temporarily store at least a portion of the images acquired via image sensor 230 for subsequent image processing tasks. For example, if image capture is delayed due to shutter lag or multiple images are captured rapidly, the acquired original image (e.g., Bayer pattern image, high-resolution image) can be stored in memory 250, and its corresponding copy image (e.g., low-resolution image) can be previewed via display device 160. Subsequently, if specified conditions are met (e.g., by user input or system command), at least a portion of the original image stored in memory 250 can be obtained and processed, for example, by image signal processor 260. According to embodiments, memory 250 may be configured as at least a portion of memory 130, or as a separate memory operating independently of memory 130.
[0057] Image signal processor 260 can perform one or more image processing operations on images acquired via image sensor 230 or stored in memory 250. One or more image processing operations may include, for example, depth map generation, 3D modeling, panorama generation, feature point extraction, image compositing, or image compensation (e.g., noise reduction, resolution adjustment, brightness adjustment, blurring, sharpening, or softening). Additionally or alternatively, image signal processor 260 can perform control (e.g., exposure time control or readout timing control) on at least one of the components included in camera module 180 (e.g., image sensor 230). Images processed by image signal processor 260 can be stored back in memory 250 for further processing, or they can be provided to external components outside camera module 180 (e.g., memory 130, display device 160, electronics 102, electronics 104, or server 108). According to embodiments, image signal processor 260 can be configured as at least a part of processor 120, or as a separate processor operating independently of processor 120. If the image signal processor 260 is configured as a processor separate from the processor 120, at least one image processed by the image signal processor 260 can be displayed as is via the display device 160 through the processor 120, or displayed after further processing.
[0058] According to an embodiment, the electronic device 101 may include a plurality of camera modules 180 with different attributes or functions. In this case, at least one of the plurality of camera modules 180 may form, for example, a wide-angle camera, and at least another of the plurality of camera modules 180 may form a telephoto camera. Similarly, at least one of the plurality of camera modules 180 may form, for example, a front-facing camera, and at least another of the plurality of camera modules 180 may form a rear-facing camera. Furthermore, the plurality of camera modules 180 may include at least one of a wide-angle camera, a telephoto camera, a color camera, a monochrome camera, or an infrared (IR) camera (e.g., a time-of-flight (TOF) camera, a structured light camera). According to an embodiment, the IR camera may serve as a sensor module (e.g., Figure 1 The sensor module 176) operates as at least a part of the sensor module. For example, a TOF camera can be used as a sensor module for detecting the distance to an object (e.g., Figure 1 At least a portion of the sensor module 176) is used to operate.

Although Figure 3 An example of an electronic device 301 including two camera modules is illustrated, but this disclosure is not limited thereto.
[0061] According to various embodiments, the body (or housing) 310 may include various components required for the operation of the electronic device 301. For example, the body 310 may include various components such as circuit boards (e.g., printed circuit boards (PCBs), flexible PCBs, or rigid-flex PCBs), processors (e.g., ... Figure 1 The processor 120), memory (e.g., Figure 1 The memory 130) or communication module (e.g., Figure 1 (Communication module 190).
[0062] According to various embodiments, the display 320 may be arranged on a first surface (e.g., the front surface) of the body 310, and the first camera module 330 and the second camera module 340 may be arranged to face the first surface. For example, the first camera module 330 and the second camera module 340 may not be visually exposed and may be under-display cameras (UDCs).

For example, when the display 320 extends to a second surface of the body 310 (e.g., the rear surface), the first camera module 330 and the second camera module 340 may be arranged facing the second surface of the body 310 (e.g., the rear surface).
[0064] The display 320 can display various content, such as text or images. The display 320 can be implemented using multiple layers. For example, the display 320 can have a structure in which window layers, touchscreen panels, display panels, and / or protective layers are stacked sequentially (see reference). Figure 4 ).
[0065] Display 320 allows external light to pass through at least a portion of the area where the first camera module 330 and the second camera module 340 are arranged. For example, display 320 allows external light to pass through the spaces between pixels included in display 320. The first camera module 330 and the second camera module 340 can use the external light incident through display 320 to capture images.
[0066] The first camera module (or first camera device) 330 and the second camera module (or second camera device) 340 can be arranged facing the first surface of the subject 310. The first camera module 330 and the second camera module 340 can be arranged on the rear surface (opposite surface to the surface displaying the image) of the display panel included in the display 320, and can be hidden so that they are not visible to the user from the outside.
[0067] According to an embodiment, the first camera module 330 and the second camera module 340 may be devices of the same type. For example, the first camera module 330 and the second camera module 340 may be devices having substantially the same modulation transfer function (MTF) characteristics. According to another embodiment, the first camera module 330 and the second camera module 340 may be devices of different types. For example, the first camera module 330 may be a camera including a wide-angle lens, while the second camera module 340 may be a camera including a telephoto lens.
[0068] According to an embodiment, the first camera module 330 and the second camera module 340 can be arranged in an area where at least a portion of the layers included in the display 320 have been removed. For example, layers that external light cannot penetrate (e.g., shielding layers) can be removed, and the lenses of the first camera module 330 and the second camera module 340 (e.g., lenses) can be placed within the display 320. Figure 4 Lenses 331 and 341 are arranged in the area where the layer has been removed.
[0069] According to various embodiments, metal layers with different patterns (hereinafter referred to as patterned layers) can be arranged in the first lens of the first camera module 330 (e.g., Figure 4 The first lens 331) and the second lens of the second camera module 340 (e.g., Figure 4 On the front surface of lens 341. For example, a patterned layer (e.g., Figure 4 The patterning layer 410 can be a layer constituting the display 320, and can be arranged between the pixels of the display panel and the lens of the camera module (see reference).

Figure 4 The camera module can be Figure 3 One of the first camera module 330 or the second camera module 340. Figure 4 This is illustrative, and this disclosure is not limited thereto.
[0071] Reference Figure 4 Display (e.g., Figure 3The display (320) may include a window layer 401, a display panel 403, and a protective layer (or, shielding layer or back cover) 480.

For example, electronic device 301 may include coil components disposed on a dielectric substrate to detect resonant frequencies of the electromagnetic induction type applied from an electronic pen. According to embodiments, display 320 may include control circuitry (not shown). For example, control circuitry (not shown) may include display driver ICs (DDI) and / or touch display driver ICs (TDDI) disposed in a chip-on-board (COP) or chip-on-film (COF) type configuration.
[0075] According to various embodiments, electronic device 301 may include a plurality of displays (e.g., a first display and a second display), and at least one of the plurality of displays may include flexible features. For example, the first display (e.g., display 320) may include an external touch AMOLED (OCTA) display, while the second display (e.g., a flexible display) may include a shatterproof (UB) type active-matrix organic light-emitting diode (OLED) display.
[0076] The display panel 403 may include a substrate layer 405, a patterning layer 410, a wiring layer 420, an emissive layer (or organic layer) 430, and an encapsulation layer (or protective layer) 440. Although Figure 4 Not shown in the figure, but the display panel 403 may also include a polarizer (e.g., a polarizing film), an adhesive layer, and a touch panel. For example, the adhesive layer may be arranged between the layers as an adhesive component (e.g., optically clear adhesive (OCA) or pressure-sensitive adhesive (PSA)).
[0077] According to various embodiments, a base layer 405 may be formed beneath a patterned layer 410 (e.g., in a direction toward camera module 330 or 340). For example, the patterned layer 410, wiring layer 420, and emission layer 430 may be stacked on the base layer 405. According to various embodiments, the base layer 405 may include a transparent insulating substrate (e.g., a substrate). For example, the base layer 405 may be implemented using a glass substrate, a quartz substrate, or a transparent resin substrate. For example, the transparent resin substrate may comprise a polyimide-based resin, an acrylic-based resin, a polyacrylate-based resin, a polycarbonate-based resin, a polyether-based resin, a sulfonic acid-based resin, and / or a polyethylene terephthalate-based resin.
[0078] A patterned layer (or bottom metal layer (BML)) 410 may be patterned in an area where at least a portion of the protective layer (or shielding layer or back cover) 480 is removed for mounting the camera module 330 or 340. The patterned layer 410 may include a blocking portion (or blocking area) 415 and an opening (or open area) 416. The blocking portion 415 may be an area at least partially corresponding to a pixel 431 of the emitting layer (organic layer) 430, while the opening 416 may be an area at least partially corresponding to a panel opening in the pixel 431 of the emitting layer (organic layer) 430. According to an embodiment, the patterned layer 410 may be formed of a metallic material and may be formed beneath the wiring layer 420 by deposition and / or patterning. The patterned layer 410 may protect the pixels 431 of the emitting layer (organic layer) 430 and may block light generated from the pixels 431. According to various embodiments, the patterned layer 410 may include a specified pattern (black matrix) for reducing the diffraction of light incident on the camera module 330 or 340, or an opaque metal layer (e.g., a buffer layer) including the specified pattern.
[0079] According to various embodiments, external light passing through opening 416 can be incident on lens 331 or 341. For example, depending on the shape or size of opening 416, the light may be diffracted or scattered, and image data distortion or image quality degradation may occur depending on the characteristics of the point spread function (PSF). The processor (or image processor) in electronic device 301 can generate an image that compensates for the image quality degradation by comparing or combining image data obtained by the first camera module 330 and the second camera module 340 (see reference). Figure 5 (and the following attached figures).
[0080] Wiring layer 420 and emitting layer 430 may have the form of depositing light-emitting elements (e.g., organic electroluminescent (EL)) on a thin-film transistor (TFT) substrate. According to various embodiments, emitting layer 430 may include pixels 431, each pixel being composed of multiple sub-pixels (e.g., red, green, and blue sub-pixels). According to various embodiments, display panel 403 may include active areas (e.g., display areas) and inactive areas (e.g., non-display areas). For example, the active area may be an area corresponding to an area where multiple pixels 431 are arranged, while the inactive area may be an area arranged around the active area and corresponding to a border area of display panel 403.
[0081] According to various embodiments, the wiring layer 420 may include TFT elements, metal wiring, insulating films, etc., for driving the respective pixels 431 in the effective area. According to various embodiments, the wiring layer 420 may include liquid crystal polymer or low-temperature polycrystalline silicon (LTPS) glass, and the plurality of pixels 431 may include thin-film transistors (TFTs) formed on the LTPS glass.
[0082] According to various embodiments, the emitting layer 430 may include a light-emitting element (e.g., an organic electroluminescent (EL)). When holes and electrons are injected from the cathode and anode into the organic EL, the organic EL can generate light.
[0083] According to various embodiments, when viewing the display panel 403 from a first surface (e.g., the front surface), at least one component of the display panel 403 and the electronic device 301 (e.g., lens 331 or 341 or sensor module (e.g., ...) Figure 1 In the sensor module 176) at least partially overlapping areas, multiple pixels 431 may not be arranged, or multiple pixels 431 may be arranged with a lower placement density than in non-overlapping areas.
[0084] According to various embodiments, the encapsulation layer 440 (e.g., a thin-film encapsulation (TFE)) may include alternating organic and inorganic layers laminated on the emitting layer 430 to protect the light-emitting element from oxygen or moisture. For example, the encapsulation layer 440 may be a pixel protection layer for protecting a plurality of pixels 431. For example, the encapsulation layer 440 may include encapsulation glass.
[0085] According to various embodiments, a protective layer (or shielding layer) 480 may support and protect the display panel 403. The protective layer 480 may block light or electromagnetic waves introduced from the display panel 403 from entering the electronic device 301. The protective layer 480 may include a black film and a metal (e.g., copper) plate. For example, the protective layer 480 disposed beneath the display panel 403 may provide a dark background to ensure the visibility of the display panel 403 and may be formed of shock-absorbing members (e.g., shock-absorbing pads) for cushioning. For example, the protective layer 480 may include an opaque metal layer (e.g., a black layer including an uneven pattern) to remove air bubbles that may form between the display panel 403 and objects attached to its underside, and to block light generated from the display panel 403 or incident from the outside, and / or a shock-absorbing pad layer (e.g., a sponge layer) for absorbing impacts.
[0086] According to various embodiments, the protective layer 480 may include heat-radiating components (e.g., graphite sheets) and / or conductive components (e.g., metal plates) for heat radiation. For example, conductive components may help strengthen electronic device 301 and may be used to shield ambient noise and disperse heat released from surrounding heat-radiating components.
[0087] According to various embodiments, at least a portion of the protective layer 480 may be open, and the lens 331 or 341 may be disposed in the open area. The pattern of the patterned layer 410 may be formed in the area where at least a portion of the protective layer 480 has been removed.
[0088] Figure 5 The illustration shows a pixel structure and a first type pattern arranged adjacent to a first camera module according to an embodiment of the present disclosure.
[0089] Reference Figure 5 The emitting layer 430 may include pixel regions 435 in which pixels are arranged and panel openings 436. Pixel regions 435 may be regions in which pixels, implemented using useful light-emitting elements (e.g., organic electroluminescence (EL)), are arranged. Panel openings 436 may be empty spaces between pixel regions 435. Panel openings 436 may have various shapes. For example, panel openings 436 may be cross-shaped polygons. In another example, panel openings 436 may have a quadrilateral shape. Panel openings 436 allow light incident from the outside to pass through, and the light passing through panel openings 436 can reach the first lens 331 and can be used to capture images.
[0090] The first portion (hereinafter referred to as the first patterned portion) (or first patterned area) 510 of the patterned layer 410 may include a first blocking portion 515 and a first type of opening 516. The first blocking portion 515 may be a region corresponding to the pixel region 435, and the first type of opening 516 may be a region corresponding to the panel opening 436.
[0091] The first blocking portion 515 prevents light generated from the pixel region 435 from entering the first lens 331. The first type of opening 516 allows light passing through the panel opening 436 to pass through.
[0092] According to one embodiment, the first blocking portion 515 may have substantially the same shape and size as the pixel region 435. For example, the first blocking portion 515 and the pixel region 435 may have a quadrilateral shape of substantially the same size. According to another embodiment, the first blocking portion 515 may have substantially the same shape as the pixel region 435, but may have a different size. For example, the first blocking portion 515 and the pixel region 435 may have a quadrilateral shape, and the first blocking portion 515 may have a larger size than the pixel region 435.
[0093] According to one embodiment, the first type of opening 516 may have substantially the same shape and size as the panel opening 436. For example, the first type of opening 516 and the panel opening 436 may be cross-shaped polygons with substantially the same size. According to another embodiment, the first type of opening 516 may have substantially the same shape as the panel opening 436, but may have a different size. For example, the first type of opening 516 and the panel opening 436 may be cross-shaped polygons, and the first type of opening 516 may have a smaller size than the panel opening 436.
[0094] The first blocking portion 515 and the first type of opening 516 can be arranged on the front surface of the first lens 331. Light passing through the panel opening 436 and the first type of opening 516 can reach the first lens 331 and can be used to capture an image. For example, image distortion or image quality degradation may occur when external light is diffracted or scattered during its passage through the panel opening 436 and the first type of opening 516. The processor (or image processor) in the electronic device 301 can transmit light through the first camera module (e.g., Figure 3 The first image data obtained by the first camera module 330 and the data obtained by the second camera module (e.g., Figure 3 The second image data obtained by the second camera module 340 is compared, and the image quality of the image can be compensated.
[0095] Figure 6The illustration shows a pixel structure and a second type pattern arranged adjacent to a second camera module according to an embodiment of the present disclosure.
[0096] Reference Figure 6 The emitting layer 430 may include pixel regions 435 in which pixels are arranged and panel openings 436. Pixel regions 435 may be regions in which pixels, implemented using useful light-emitting elements (e.g., organic electroluminescence (EL)), are arranged. Panel openings 436 may be empty spaces between pixel regions 435. Panel openings 436 may have various shapes. For example, panel openings 436 may be cross-shaped polygons. In another example, panel openings 436 may have a quadrilateral shape. Panel openings 436 allow light incident from the outside to pass through, and the light passing through panel openings 436 can reach the second lens 341 and can be used to capture images.
[0097] The second portion (hereinafter referred to as the second patterned portion) (or second patterned area) 610 of the patterned layer 410 may include a second blocking portion 615 and a second type of opening 616. The second blocking portion 615 may be a region corresponding to the pixel region 435, and the second type of opening 616 may be a region corresponding to the panel opening 436.
[0098] The second blocking portion 615 prevents light generated from the pixel area 435 from entering the second lens 341. The second type of opening 616 allows light passing through the panel opening 436 to pass through.
[0099] According to one embodiment, the second blocking portion 615 may have a different shape than the pixel region 435, but may have substantially the same size as the pixel region 435. For example, when the pixel region 435 has a quadrilateral shape, the second blocking portion 615 may have a rhombus shape, which has substantially the same size as the pixel region 435. According to another embodiment, the second blocking portion 615 may have a different shape and size than the pixel region 435. For example, when the pixel region 435 has a quadrilateral shape, the second blocking portion 615 may have a rhombus shape, which is larger than the pixel region 435.
[0100] According to an embodiment, the second blocking portion 615 disposed on the front surface of the second lens 341 can have such a shape that the portion disposed on the front surface of the second lens 341 is... Figure 5 The first blocking portion 515 on the front surface of the first lens 331 is rotated by a specified angle. For example, when the first blocking portion 515 has a square shape, the second blocking portion 615 can have a rhombus shape, wherein the first blocking portion 515 is rotated by 45 degrees.
[0101] According to an embodiment, the second type of opening 616 may have a different shape than the panel opening 436. The second type of opening 616 and the panel opening 436 may have a common main area through which light can pass, and may have different boundaries. For example, when the panel opening 436 is a cross-shaped polygon, the second type of opening 616 may have an octagonal shape.
[0102] The second blocking portion 615 and the second type of opening 616 can be arranged on the front surface of the second lens 341. Light passing through the panel opening 436 and the second type of opening 616 can reach the second lens 341 and can be used to capture images. For example, image distortion or image quality degradation may occur when external light is diffracted or scattered during its passage through the panel opening 436 and the second type of opening 616. The processor (or image processor) in the electronic device 301 can transmit light through the second camera module (e.g., Figure 3 The second image data obtained by the second camera module 340) and the second image data obtained by the first camera module (e.g., Figure 3 The first image data obtained by the first camera module 330 is compared, and the image quality of the image can be compensated.
[0103] When the first camera module 330 and the second camera module 340 are devices with essentially the same characteristics (e.g., MTF characteristics), image compensation can be performed through simple operation. When the first camera module 330 and the second camera module 340 are devices with different characteristics, additional processing depending on the characteristics of the camera modules may be required.
[0104] Figure 7 The illustration shows the configuration of an image processor according to an embodiment of the present disclosure. Figure 7 This is illustrative, and the disclosure is not limited thereto. The image processor 710 may be operated by a processor in the electronic device 301, or may be operated under the control of a processor. Alternatively, the image processor 710 may be a computing element implemented separately from a processor.
[0105] Reference Figure 7 The first camera module 330 may include a first lens 331 and a first image sensor 332. The first camera module 330 may collect light passing through the first patterned portion 510 through the first lens 331. The first image sensor 332 may convert the light collected through the first lens 331 into electrical signals.
[0106] The second camera module 340 may include a second lens 341 and a second image sensor 342. The second camera module 340 may collect light passing through the second patterned portion 610 through the second lens 341. The second image sensor 342 may convert the light collected through the second lens 341 into electrical signals.
[0107] According to various embodiments, the image processor 710 may include a first converter 711, a second converter 712, a combiner 730, and a compensator 740. The components are divided according to their function, and this disclosure is not limited thereto.
[0108] The first converter 711 can convert first image data collected by the first image sensor 332. The second converter 712 can convert second image data collected by the second image sensor 342. For example, the first converter 711 and the second converter 712 can perform a conversion (e.g., plane correction) such that the first image data and the second image data are projected onto a common plane.
[0109] Combiner 730 can combine the converted first image data and the converted second image data into a single image. According to an embodiment, combiner 730 can combine (e.g., fuse) the first image data and the second image data into a single image by reflecting the MTF characteristics of the first camera module 330 and the second camera module 340.
[0110] The compensator 740 can compensate for (e.g., recover) attenuated signal components by reflecting the characteristics of the first camera module 330 and the second camera module 340. The first patterning portion 510 can alter the MTF characteristics of the first camera module 330, while the second patterning portion 610 can alter the MTF characteristics of the second camera module 340. The attenuation of specific signal components, depending on the changes in the MTF characteristics of lenses 331 or 341, may be a major cause of image quality degradation in the display camera.
[0111] For example, when the first camera module 330 and the second camera module 340 are devices with substantially the same characteristics, the combiner 730 can combine the first image data and the second image data using a simple addition method. In another example, when the first camera module 330 and the second camera module 340 are devices with different characteristics, the combiner 730 can combine the first image data and the second image data by reflecting the MTF characteristics of the first camera module 330 and the second camera module 340.
[0112] Figure 8 The illustration shows a variation in the MTF characteristics of a display camera according to an embodiment of the present disclosure. Figure 8 In the middle, the patterned portion 850 can be the first patterned portion (e.g., Figure 5 The first patterned part 510).
[0113] refer to Figure 8The patterned portion 850 may include a blocking portion 855 and an opening 856. The MTF characteristics of the display camera may vary due to the patterned portion 850 (e.g., variation 801). The MTF may be a curve obtained by quantifying the variation in resolution based on the distance from the center point of the image. Resolution can mean the ability to represent different objects, making them optically distinguishable from each other, and can be associated with contrast, sharpness, or agility. For example, a camera module (e.g., Figure 4 The camera module 330 or 340 can obtain a lens (e.g., included in the camera module 330 or 340) that is compatible with the lens included in the camera module 330 or 340. Figure 4 The MTF curve is essentially the same as the limiting diffraction curve of lens 331 or 341. For example, the MTF curve can mean an expression of camera performance with a specified value or greater modulation pass (e.g., contrast input / output ratio) regarding contrast in the low frequency band.
[0114] The lens's unique MTF characteristics (characteristics lacking patterned portion 850) can have the following form, where the MTF amplitude gradually decreases with increasing frequency, as shown in the first pattern 810. The first pattern 810 can have a near-linear form without individual ripple. For example, in camera modules 330 or 340 arranged on a display panel (e.g., Figure 4 In the case of the rear surface (the surface opposite to the surface displaying the image) of the display panel 403, depending on the patterning layer of the display panel 430 (e.g., Figure 4 Patterned layer 410) or emission layer (e.g., Figure 4 The structure of the emitting layer 430 may cause diffraction or scattering of various frequencies in the external light entering the camera module 330 or 340. For example, when diffraction or scattering occurs, the MTF of each frequency (e.g., spatial frequency) of the light may fluctuate in a curved form (e.g., ripple or sine wave form) rather than a linear form (e.g., the phenomenon of MTF generally decreasing), and this phenomenon may cause a degradation in the image quality of the camera module 330 or 340.
[0115] For example, when the patterned portion 850 is arranged on the front surface of the lens, certain frequency components may be attenuated depending on the length of the patterned portion 850 in the vertical / horizontal directions A1 and A2 or the length of the patterned portion 850 in the diagonal directions B1 and B2. This can lead to a deterioration in image quality. For example, the MTF characteristics of the display camera may vary depending on the shape (e.g., size or shape) of the patterned portion 850.
[0116] The lengths of opening 856 in the vertical / horizontal directions A1 and A2 and the lengths of opening 856 in the diagonal directions B1 and B2 can be different from each other.
[0117] Typically, the line spread function (LSF) or point spread function (PSF) of a lens can bring an image to the diffraction limit known as the Airy disk. The location where the dark pattern appears on the image is represented by Equation 1 below.
[0118] [Equation 1]
[0119]
[0120] z: Location where the dark pattern forms
[0121] d: Diameter of the aperture
[0122] λ: wavelength
[0123] As shown in Equation 1, the diffraction limit may be inversely proportional to the aperture diameter. In the case of a lower display camera, the diffraction characteristics can be determined by the lengths in the vertical / horizontal directions A1 and A2 or the lengths in the diagonal directions B1 and B2.
[0124] For example, when the patterned portion 850 is arranged on the front surface of the lens, the MTF characteristics in the vertical / horizontal directions A1 and A2 can have a rippled form, where, as shown in the second pattern 811, attenuation occurs in a first frequency range of 0 to 0.1, a third frequency range of 0.2 to 0.3, and a fifth frequency range of 0.4 to 0.5. The MTF characteristics in the diagonal directions B1 and B2 can also have a rippled form, where, as shown in the third pattern 812, attenuation occurs in a second frequency range of 0.1 to 0.2 and a fourth frequency range of 0.3 to 0.4. Rippled MTF characteristics can lead to image distortion and / or degraded image quality. For example, the processor can remove the ripple through a separate compensation operation (see...). Figure 9 ).
[0125] According to various embodiments, when the patterned portions 850 have the same shape and the length of the patterned portions 850 varies, the MTF characteristics can vary accordingly. For example, when the length of the patterned portions 850 in the vertical / horizontal directions A1 and A2 or the length of the patterned portions 850 in the diagonal directions B1 and B2 varies, the forms of the second pattern 811 and the third pattern 812 can vary accordingly.
[0126] Figure 9 The illustration shows compensation for image quality degradation through image combination according to an embodiment of the present disclosure.
[0127] Reference Figure 9 In the first graphic 901, the first lens (e.g., Figure 5 The unique MTF characteristics of the first shot 331 (e.g., lack of Figure 5The characteristics of the first patterned portion 510 can have the following form, where, as shown in the first MTF pattern 910, the amplitude of the MTF gradually decreases with increasing frequency. The first MTF pattern 910 can have a near-linear form without individual ripples.
[0128] When the first patterned portion 510 is arranged on the front surface of the first lens 331, certain frequency components may be attenuated depending on whether it is a vertical / horizontal direction as a first direction or a diagonal direction as a second direction. As a result, image quality may be degraded.
[0129] For example, when the first patterned portion 510 is disposed on the front surface of the first lens 331, the MTF pattern 1-1 911 in the horizontal / vertical direction and the MTF pattern 1-2 912 in the diagonal direction may have a rippled form. The first ripple in the horizontal / vertical direction and the second ripple in the diagonal direction may have opposite characteristics. For example, when the first ripple in the horizontal / vertical direction increases, the second ripple in the diagonal direction may decrease, and when the first ripple in the horizontal / vertical direction decreases, the second ripple in the diagonal direction may increase.
[0130] In the second figure 902, the second lens (e.g., Figure 6 The unique MTF characteristics of the second lens 341 (e.g., lack of Figure 6 The characteristics of the second patterned portion 610 can have the following form, where, as shown in the second MTF pattern 920, the amplitude of the MTF gradually decreases with increasing frequency. The second MTF pattern 920 can have a near-linear form without individual ripples.
[0131] According to an embodiment, when the first camera module 330 and the second camera module 340 are devices with substantially the same characteristics, the unique MTF characteristics of the first lens 331 can be substantially the same as the unique MTF characteristics of the second lens 341.
[0132] When the second patterned portion 610 is disposed on the front surface of the second lens 341, certain frequency components may be attenuated depending on whether the direction is vertical / horizontal (as the first direction) or diagonal (as the second direction). This may result in a decrease in image quality.
[0133] For example, when the second patterned portion 610 is disposed on the front surface of the second lens 341, the MTF pattern 2-1 921 in the horizontal / vertical direction and the MTF pattern 2-2 922 in the diagonal direction may have a rippled form. The third ripple in the horizontal / vertical direction and the fourth ripple in the diagonal direction may have opposite characteristics. For example, when the third ripple in the horizontal / vertical direction increases, the fourth ripple in the diagonal direction may decrease, and when the third ripple in the horizontal / vertical direction decreases, the fourth ripple in the diagonal direction may increase.
[0134] According to various embodiments, the MTF pattern 1-1 911 of the first camera module 330 in the horizontal / vertical direction may be the same as or similar to the MTF pattern 2-2 922 of the second camera module 340 in the diagonal direction. The MTF pattern 1-2 912 of the first camera module 330 in the diagonal direction may be the same as or similar to the MTF pattern 2-1921 of the second camera module 340 in the horizontal / vertical direction.
[0135] According to various embodiments, the processor of electronic device 301 (e.g., Figure 7 The image processor 710 can combine first image data from the first camera module 330 and second image data from the second camera module 340. For example, MTF pattern 3-1931 can be a value obtained by combining or averaging the MTF pattern 1-1911 of the first camera module 330 in the horizontal / vertical direction and the MTF pattern 2-2922 of the second camera module 340 in the diagonal direction. MTF pattern 3-2932 can be a value obtained by combining or averaging the MTF pattern 1-2912 of the first camera module 330 in the diagonal direction and the MTF pattern 2-1922 of the second camera module 340 in the vertical / horizontal direction.
[0136] In the third pattern 903, the third MTF pattern 940 of the combined image data can have a form where ripple is canceled, and can have a form where the amplitude of the MTF gradually decreases with increasing frequency. The third MTF pattern 940 of the combined image data can be similar to the second MTF pattern 920 or the first MTF pattern 910.
[0137] processor (or, Figure 7The image processor 710 can use the combined image data without modification, or it can compensate the combined image data in the form of a third MTF pattern 940 that is closer to the first MTF pattern 910 or the second MTF pattern 920. In this case, the processor can process data with low distortion for each frequency. Therefore, when processing the signal used for recovery (e.g., boost-up), mismatches for each frequency can be robust and compensation can be easily performed.
[0138] According to various embodiments, in the case of multiple cameras, the blocking portion constitutes a pattern arranged in front of the lens (e.g., Figure 5 The first blocking part 515 and Figure 6 The second blocking section 615 can rotate at different angles, causing the phases of the ripples to intersect each other. The rotation angle of each blocking section can be calculated using Equation 2 below.
[0139] [Equation 2]
[0140]
[0141] Angle between BML patterns
[0142] n: Number of cameras
[0143] For example, when two cameras are set up, the angle between the patterns placed in front of the lenses can be approximately 45 degrees, while when four cameras are set up, the angle between the patterns placed in front of the lenses can be approximately 22.5 degrees.
[0144] Figure 10 The illustration shows the light burst effect of a light source according to an embodiment of the present disclosure.
[0145] Reference Figure 10 When shooting with essentially the same light source, in the first image 1010 captured by the first camera module 330, the flare in the up / down direction (first direction) can be relatively long, while the flare in the diagonal direction (second direction) can be relatively short. In the second image 1020 captured by the second camera module 340, the flare in the up / down direction (first direction) can be relatively short, while the flare in the diagonal direction (second direction) can be relatively long.
[0146] The processor can combine the first image 1010 and the second image 1020 to generate a third image 1030, which includes light spots uniformly arranged in the first and second directions. This is achieved by using patterned portions with different patterns (e.g., Figure 5 The first patterned part 510 and Figure 6 The second patterning part (610) can eliminate distortion or reduce the degree of distortion and reduce the computational complexity of the processor.
