Technical Field
[0001] The present disclosure relates to an integrated sensor-lens assembly (ISLA) for an image capture device. Background Art
[0002] Image capture devices are used in a variety of applications (e.g., handheld cameras and video recorders, cellular phones, drones, vehicles, etc.) and include one or more lenses (or other such optical elements) and one or more image sensors. The one or more lenses capture content by receiving and focusing light, and the one or more image sensors convert the captured content into electronic image signals that are processed by an image signal processor to generate an image. In some image capture devices, the one or more lenses and the one or more image sensors are integrated into a single unit, which is referred to as an ISLA.
[0003] In order to produce a high-quality focused image, one or more lenses and one or more corresponding sensors must be properly aligned in multiple degrees of freedom, because even a small misalignment (e.g., the position or tilt of one or more lenses and / or one or more image sensors) can negatively affect image quality. To address this issue, the present disclosure describes various structures, components, and methods that improve the alignment and connection of components of an ISLA during assembly of an image capture device.

[0062] Figure 3 is a top view of the image capture device 300. The image capture device 300 and FIG. 2A to FIG. 2B The image capture device 200 is similar to that of FIG. 1 , and is configured to capture spherical images.
[0063] like Figure 3 As shown, the first image capture device 304 includes a first lens 330, and the second image capture device 306 includes a second lens 332. For example, the first image capture device 304 can capture a first image, such as a first hemispherical image or a hyper-hemispherical image, the second image capture device 306 can capture a second image, such as a second hemispherical image or a hyper-hemispherical image, and the image capture device 300 can generate a spherical image that merges or combines the first image and the second image, which are captured simultaneously or substantially simultaneously.
[0064] The first image capture device 304 defines a first field of view 340 in which the first lens 330 of the first image capture device 304 receives light. The first lens 330 directs the received light corresponding to the first field of view 340 onto a first image sensor 342 of the first image capture device 304. For example, the first image capture device 304 may include a first lens barrel (not explicitly shown) extending from the first lens 330 to the first image sensor 342. In the illustrated embodiment, the first lens 330 and the first image sensor 342 are integrated into a single unit, whereby the first image capture device 304 is configured as a first ISLA 326 defining a first optical axis Xi.
[0065] The second image capture device 306 defines a second field of view 344 in which the second lens 332 receives light. The second lens 332 directs the received light corresponding to the second field of view 344 onto a second image sensor 346 of the second image capture device 306. For example, the second image capture device 306 may include a second lens barrel (not explicitly shown) extending from the second lens 332 to the second image sensor 346. In the illustrated embodiment, the second lens 332 and the second image sensor 346 are integrated into a single unit, whereby the second image capture device 306 is configured as a second ISLA 328 defining a second optical axis X1i.
[0066] The boundary 348 of the first field of view 340 is shown using dashed directional lines. The boundary 350 of the second field of view 344 is shown using dashed directional lines. As shown, the image capture devices 304, 306 are arranged in a back-to-back (Janus) configuration so that the lenses 330, 332 face opposite directions (e.g., a forward direction and a rearward direction), and so that the image capture device 300 can capture a spherical image. The first image sensor 342 captures a first hyper-hemispherical image plane from light entering the first lens 330. The second image sensor 346 captures a second hyper-hemispherical image plane from light entering the second lens 332.
[0067] like Figure 3 As shown, the fields of view 340, 344 partially overlap, such that the combination of the fields of view 340, 344 forms a spherical field of view, except that one or more uncaptured regions 352, 354 may be outside the fields of view 340, 344 of the lenses 330, 332. Light emitted from or passing through the uncaptured regions 352, 354 (which may be near the image capture device 300) may be blocked by the lenses 330, 332 and corresponding image sensors 342, 346, such that content corresponding to the uncaptured regions 352, 354 may be omitted from an image captured by the image capture device 300. In some implementations, the image capture devices 304, 306 or their lenses 330, 332 may be configured to minimize the uncaptured regions 352, 354.
[0068] Examples of transition points or overlap points from the uncaptured regions 352 , 354 to the overlapping portions of the fields of view 340 , 344 are shown at 356 , 358 .
[0069] The images captured simultaneously by the respective image sensors 342, 346 may be combined to form a combined image, such as a spherical image. Generating the combined image may include correlating overlapping areas captured by the respective image sensors 342, 346; aligning the captured fields of view 340, 344; and stitching the images together to form a cohesive combined image. Stitching the images together may include correlating overlapping points 356, 358 with corresponding locations in corresponding images captured by the image sensors 342, 346. Although Figure 3 A plan view of the fields of view 340, 344 is shown in FIG, but the fields of view 340, 344 are hyper-hemispherical fields of view.
[0070] Changing the alignment (such as position, tilt, or a combination thereof) of the image capture devices 304, 306 (such as lenses 330, 332, image sensors 342, 346, or both) may change the relative positions of the respective fields of view 340, 344, may change the positions of the overlap points 356, 358 (such as relative to the image captured by the image sensors 342, 346), and may change the uncaptured areas 352, 354, which may include changing the uncaptured areas 352, 354 in an uneven manner.
[0071] Incomplete or inaccurate information indicating the alignment of the image capture devices 304, 306, such as the location of the overlap points 356, 358, may reduce the accuracy, efficiency, or both of generating the combined image. In some implementations, the image capture device 300 may maintain information indicating the location and orientation of the image capture devices 304, 306 (such as the lenses 330, 332, the image sensors 342, 346, or both) so that the fields of view 340, 344, the overlap points 356, 358, or both can be accurately determined, which can improve the accuracy, efficiency, or both of generating the combined image.
[0072] As shown, the ISLAs 326, 328 (e.g., lenses 330, 332) can be aligned (e.g., so that the optical axes Xi, Xii coincide with each other), laterally offset from each other (not shown), offset from the central axis of the image capture device 300 (not shown), or laterally offset and offset from the central axis (not shown). Whether by using an offset or by using a compact image capture device 304, 306, a reduction in the distance between the lenses 330, 332 may improve the overlap in the fields of view 340, 344, such as by reducing the uncaptured areas 352, 354.
[0073] The images or frames captured by the image capture devices 304, 306 may be combined, fused, or stitched together to generate a combined image, such as a spherical image or a panoramic image, which may be an equirectangular plane image. In some implementations, generating the combined image may include using techniques such as noise reduction, tone mapping, white balance, or other image corrections. In some implementations, pixels along the stitching boundary that may correspond to the overlap points 356, 358 may be accurately matched to minimize boundary discontinuities.
[0074] Figure 4 4 is a block diagram of the electronic components in image capture device 400. Image capture device 400 may be a single-lens image capture device, a multi-lens image capture device, or variations thereof, including image capture devices with multiple capabilities (such as using interchangeable integrated sensor-lens assemblies).

One image sensor 412 is shown in FIG. 4, but the capture component 410 may include multiple image sensors. The image sensor 412 may be connected to Figure 3 The image sensors 342 and 346 are similar. The image sensor 412 may be, for example, a charge coupled device (CCD) sensor, an active pixel sensor (APS), a complementary metal oxide semiconductor (CMOS) sensor, or an N-type metal oxide semiconductor (NMOS) sensor. Figure 3As shown, the image sensor 412 detects light within a defined spectrum (such as a visible spectrum or an infrared spectrum) that is incident through a corresponding lens (such as the first lens 330 with respect to the first image sensor 342 or the second lens 332 with respect to the second image sensor 346). The image sensor 412 captures the detected light as image data and transmits the captured image data as an electrical signal (image signal or image data) to other components of the image capture device 400, such as the processing component 420, such as via the bus 480.
[0077] Capture component 410 includes microphone 414 for capturing audio. Figure 4 4, but the capture component 410 may include multiple microphones. The microphone 414 detects and captures or records sound, such as sound waves incident on the microphone 414. The microphone 414 can detect, capture or record sound in conjunction with the captured image by the image sensor 412. The microphone 414 can detect sound to receive audible commands to control the image capture device 400. The microphone 414 can be used in conjunction with the captured image by the image sensor 412. Figure 1A to Figure 1B The microphones 128, 130, 132 or FIG. 2A to FIG. 2B The illustrated audio components 218, 220, 222 are similar.
[0078] The processing component 420 performs image signal processing (such as filtering, tone mapping, or splicing) based on the image data obtained from the image sensor 412 to generate or obtain a processed image or processed image data. The processing component 420 may include one or more processors having a single processing core or multiple processing cores. In some implementations, the processing component 420 may include or may be an application specific integrated circuit (ASIC) or a digital signal processor (DSP). For example, the processing component 420 may include a customized image signal processor. The processing component 420 uses other components of the image capture device 400 via the bus 480 to transmit data (e.g., processed image data). In some implementations, the processing component 420 may include an encoder, such as an image decoder or video encoder that can encode, decode, or both image data, such as for compression encoding, code conversion, or a combination thereof.
[0079] Although not in Figure 4 Although not explicitly shown in FIG. 4 , processing component 420 may include memory, such as a random access memory (RAM) device, which may be a non-transitory computer-readable memory. The memory of processing component 420 may include executable instructions and data that can be accessed by processing component 420.
[0080] The data interface component 430 communicates with other electronic devices such as external electronic devices (such as remote controls, smart phones, tablet computers, laptop computers, desktop computers, or external computer storage devices). For example, the data interface component 430 can receive commands to operate the image capture device 400. In another example, the data interface component 430 can transmit image data to transmit the image data to other electronic devices. The data interface component 430 can be configured to perform wired communication, wireless communication, or both. As shown, the data interface component 430 includes an I / O interface 432, a wireless data interface 434, and a storage interface 436. In some implementations, one or more of the following may be omitted or combined: the I / O interface 432, the wireless data interface 434, or the storage interface 436.
[0081] I / O interface 432 can send, receive, or send and receive wired electronic communication signals. For example, I / O interface 432 can be a universal serial bus (USB) interface, such as a USB Type-C interface, a high-definition multimedia interface (HDMI), a FireWire interface, a digital video interface link, a display port interface link, a video electronics standards associated (VESA) digital display interface link, an Ethernet link, or a Thunderbolt link. Although Figure 4 FIG. 4 shows one I / O interface 432, but the data interface unit 430 includes multiple I / O interfaces. The I / O interface 432 can be connected to Figure 1B The data interface 124 shown is similar.
[0082] The wireless data interface 434 can send, receive, or send and receive wireless electronic communication signals. The wireless data interface 434 can be a Bluetooth interface, a ZigBee interface, a Wi-Fi interface, an infrared link, a cellular link, a near field communication (NFC) link, or an Advanced Network Technology Interoperability (ANT+) link. Figure 4 4 shows one wireless data interface 434, but the data interface component 430 includes multiple wireless data interfaces. The wireless data interface 434 can be connected to Figure 1B The data interface 124 shown is similar.
[0083] The storage interface 436 may include a memory card connector, such as a memory card receiving portion, configured to receive and operably couple to a removable storage device (such as a memory card) and transfer (such as read, write, or read and write) data between the image capture device 400 and the memory card (such as for storing images captured by the image capture device 400, recorded audio, or both on the memory card). Although Figure 4 4 shows one storage interface 436, but the data interface component 430 includes multiple storage interfaces. The storage interface 436 can be connected to Figure 1BThe data interface 124 shown is similar.
[0084] The spatial sensor or spatiotemporal sensor 440 detects the spatial position, movement, or both of the image capture device 400. Figure 4 As shown, spatial sensor 440 includes position sensor 442, accelerometer 444, and gyroscope 446. Position sensor 442 (which may be a global positioning system (GPS) sensor) can determine the geospatial location of image capture device 400, which may include: time data such as obtained (such as obtained by receiving) via GPS signals. Accelerometer 444 (which may be a three-axis accelerometer) can measure linear motion, linear acceleration, or both of image capture device 400. Gyroscope 446 (which may be a three-axis gyroscope) can measure rotational motion of image capture device 400, such as rotation rate. In some implementations, spatial sensor 440 may include other types of spatial sensors. In some implementations, one or more of the following may be omitted or combined: position sensor 442, accelerometer 444, and gyroscope 446.
[0085] The power component 450 distributes power to the components of the image capture device 400 for operating the image capture device 400. Figure 4 As shown, power component 450 includes battery interface 452, battery 454, and external power interface 456 (external power interface). Battery interface 452 (battery interface) is operably coupled to battery 454, such as via conductive contacts, to transfer power from battery 454 to other electronic components of image capture device 400. Battery interface 452 can be connected to Figure 1B The external power interface 456 obtains or receives power from an external source (such as a wall plug or an external battery) and distributes the power to the components of the image capture device 400, which may include distributing power to the battery 454 via the battery interface 452 to charge the battery 454. Although Figure 4 4 shows a battery interface 452, a battery 454, and an external power interface 456, but any number of battery interfaces, batteries, and external power interfaces may be used. In some implementations, one or more of the following may be omitted or combined: battery interface 452, battery 454, and external power interface 456. For example, in some implementations, external power interface 456 and I / O interface 432 may be combined.
[0086] User interface component 460 receives input (such as user input) from a user of image capture device 400, outputs (e.g., displays or presents) information to the user, or both receives input and outputs information (such as information consistent with the user's interaction with image capture device 400).
[0087] like Figure 4 As shown, the user interface component 460 includes a visual output component 462 for conveying information in a visual manner to present the captured image. As shown, the visual output component 462 includes an indicator 464 and a display 466. The indicator 464 can be connected to Figure 1A The indicator 106 shown or FIG. 2A to FIG. 2B The display 466 may be similar to the indicator 208 shown. Figure 1A The display 108 shown, Figure 1B The display 142 or Figure 2B The display 224 is similar to that shown. Although the visual output component 462 is Figure 4 Although shown as including one indicator 464, the visual output component 462 may include multiple indicators. Figure 4 466, but the visual output component 462 may include multiple displays. In some implementations, one or more indicators 464 or displays 466 may be omitted or combined.
[0088] like Figure 4 As shown, the user interface component 460 includes a speaker 468. The speaker 468 can be used with Figure 1B The speaker 138 shown or FIG. 2A to FIG. 2B The audio components 218, 220, 222 are shown to be similar. Figure 4 One speaker 468 is shown in FIG, but the user interface component 460 may include multiple speakers. In some implementations, the speaker 468 may be omitted, or the speaker 468 may be combined with another component of the image capture device 400 (such as the microphone 414).
[0089] like Figure 4 As shown, the user interface component 460 includes a physical input interface 470. The physical input interface 470 can be connected to Figure 1A , Figure 2A The mode buttons 110, 210 or Figure 1A , Figure 2B The shutter buttons 112, 212 are shown similar. Figure 4 4, one physical input interface 470 is shown, but the user interface component 460 may include multiple physical input interfaces. In some implementations, the physical input interface 470 may be omitted, or the physical input interface 470 may be combined with another component of the image capture device 400. The physical input interface 470 may be, for example, a button, a toggle switch, a switch, a dial, or a slider.
[0090] like Figure 4As shown, user interface component 460 includes a dashed border labeled "Other" to indicate that components of image capture device 400 other than those explicitly shown as included in user interface component 460 can be user interface components. For example, microphone 414 can receive or capture and process audio signals to obtain input data, such as user input data corresponding to voice commands. In another example, image sensor 412 can receive or capture and process image data to obtain input data, such as user input data corresponding to visible gesture commands. In another example, one or more of spatial sensors 440, such as a combination of accelerometer 444 and gyroscope 446, can receive or capture and process motion data to obtain input data, such as user input data corresponding to motion gesture commands.
[0091] Now, refer to Figures 5 to 7 , the optical module 500 is discussed, and the optical module 500 can be configured to be used with the aforementioned spherical image capture device (e.g., the image capture device 200 ( Figure 2A , Figure 2B )、Image capture device 300( Figure 3 ) etc.) are used together with any spherical image capture device. More specifically, Figure 5 is a cross-sectional perspective view of the optical module 500; Figure 6 is an axial (longitudinal) cross-sectional view of optical module 500; and Figure 7 yes Figure 5 Magnified view of the detail area identified in .
[0092] The optical module 500 includes respective first ISLAs 502a and second ISLAs 502b that define respective optical axes Xa, Xb and are similar (e.g., (substantially) identical) in configuration. Thus, throughout the following disclosure, only the ISLA 502a is described in detail. The ISLAs 502a, 502b include the ISLAs 326, 328 described above in conjunction with the aforementioned ISLAs. Figure 3 ) are similar to the components and features discussed in the ISLA 326, 328, 502, and therefore, for the sake of brevity, only the differences will be discussed. Therefore, the same reference numerals will be used to refer to the elements, structures, features, etc. common to the ISLA 326, 328, 502.
[0093] Although generally illustrated in the context of a spherical image capture device in which the ISLAs 502a, 502b are (substantially) aligned (e.g., such that the respective optical axes Xa, Xb (substantially) coincide), embodiments are also contemplated in which the optical module 500 may be configured such that the ISLAs 502a, 502b are not aligned (e.g., such that the respective optical axes Xa, Xb are offset from each other). It is also contemplated herein that a single ISLA 502 may be used for a non-spherical image capture device (such as the image capture device 100 ( Figure 1A , Figure 1B )) and these embodiments will not exceed the scope of this disclosure.
[0094] Each ISLA 502 includes: a lens holder (mount) 504; a lens barrel 506, which houses (includes, contains) an optical group 508, which includes a lens 330 and receives light and directs the light onto an image sensor 342; a printed circuit board (PCB) subassembly 510, which is fixed (connected) to the lens holder 504; and an electrical connector 512.
[0095] The lens holder 504 has an inner end 514 and an outer end 518, the inner end 514 defining an inner mounting surface 516. The lens holder 504 defines an outer radial wall 520 extending (substantially) parallel to an optical axis X of the lens holder 504 (e.g., optical axis Xa defined by ISLA 502a and optical axis Xb defined by ISLA 502b), and an internal cavity 522 extending between the ends 514, 518 of the lens holder 504 and configured to receive the lens barrel 506 such that the lens barrel 506 protrudes from the outer end 518.
[0096] Lens barrel 506 is placed within lens holder 504 and secured (attached) to lens holder 504 (e.g., concentrically located within interior chamber 522) such that lens barrel 506, and therefore optical group 508, is fixed relative to lens holder 504. For example, it is contemplated that lens barrel 506 may be adhesively secured (attached) to lens holder 504, and / or it is contemplated that lens barrel 506 may be mechanically secured (attached) to lens holder 504 (e.g., via one or more mechanical fasteners).
[0097] PCB subassembly 510 includes a printed circuit board (PCB) 524 and a cover glass holder 526 .
[0098] PCB 524 has an inner face 528 and an outer face 530. Outer face 530 supports image sensor 342 and defines channel 532 ( Figure 7), the channel 532 extends into the outer surface 530 in a manner (substantially) parallel to the optical axis X, thereby defining an outer mounting surface 534.
[0099] Cover glass holder 526 has respective inner and outer ends 536 and 538 ( Figure 6 ), and at the corresponding first interface 540 and the second interface 542 ( Figure 5 ) is fixed (connected) to both the lens holder 504 and the PCB 524, and the first interface 540 and the second interface 542 are axially spaced from each other along the optical axis X. Therefore, the cover glass holder 526 is placed between the lens holder 504 and the PCB 524, and indirectly connects the lens holder 504 and the PCB 524, so that the lens holder 504 and the PCB 524 are axially spaced from each other along the optical axis X without any direct connection. More specifically, the outer end 538 of the cover glass holder 526 is fixed (connected) to the inner end 514 of the lens holder 504 (via a (first) adhesive 544 placed therebetween) so as to define a (first) joint 546, which is subjected to a UV and thermal curing process, as described in further detail below, and the inner end 536 of the cover glass holder 526 is fixed (connected) to the outer surface 530 of the PCB 524 (via a (second) adhesive 548 placed therebetween) so as to define a (second) joint 550, which is subjected to a standard curing process (e.g., air curing). For example, in some embodiments, it is contemplated that the adhesive 544 may include an active alignment adhesive 552, while the adhesive 548 may include a standard adhesive 554, solder, or any other suitable means of fixing (connecting) the cover glass holder 526 to the PCB 524. Thus, the adhesives 544, 548 differ not only in composition, but also in curing process.
[0100] Cover glass holder 526 supports cover glass 556, which protects image sensor 342 from particles, debris, dust, etc., and acts as a filter for ISLA 502. Now, with specific reference to Figure 7, the coverslip holder 526 includes an inner module (component) 558 and an outer module (component) 560, which is connected to the inner module 558. In the illustrated embodiment, the modules 558, 560 are configured as discrete components of the coverslip holder 526, which include (e.g., are formed of) different (dissimilar) (e.g., respective first and second) construction materials, which can be connected (fixed) together in any suitable manner (e.g., via adhesives, welding, etc.). For example, it is contemplated that the inner module 558 may include a polyamide (e.g., PA9T) (e.g., may be partially or completely formed of a polyamide (e.g., PA9T)), and the outer module 560 may include a liquid crystal polymer (e.g., may be partially or completely formed of a liquid crystal polymer). However, embodiments in which the modules 558, 560 may include similar (e.g., the same) construction materials and embodiments in which the coverslip holder 526 may be of a unitary construction are also contemplated herein. For example, Figure 8 is a cross-sectional perspective view of an alternative embodiment of optical module 500 in which modules 558, 560 are integrally (monolithically) formed (eg, via injection molding of a common material) such that coverslip holder 526 comprises a unitary construction.
[0101] Inner module 558 includes base 562, inner ring 564, and outer ring 566. As described in further detail below, inner module 558 is positioned around image sensor 342 (e.g., surrounds image sensor 342) and supports cover glass 556 such that inner module 558 and cover glass 556 cover image sensor 342.
[0102] The base 562 extends in a manner (substantially) orthogonal (perpendicular) to the optical axis X and includes an aperture 568 that is aligned with the optical group 508 ( Figure 5 , Figure 6 ) and image sensor 342 (substantially) aligned so as to allow light entering lens barrel 506 to be directed onto image sensor 342. Base 562 defines respective inner and outer end walls 570, 572, and outer radial wall 574, each of which extends in a manner (substantially) orthogonal (perpendicular) to optical axis X. In the illustrated embodiment, outer radial wall 574 is chamfered (beveled) such that outer radial wall 574 extends at an acute angle relative to optical axis X, which facilitates assembly of ISLA 502 (e.g., by reducing tolerances). However, embodiments of inner module 558 are also contemplated herein where outer radial wall 574 may instead extend in a manner (substantially) parallel to optical axis X, and such embodiments would not exceed the scope of the present disclosure.
[0103] The inner ring 564 is defined by a (substantially) annular (first) flange 576 extending axially outwardly from the base 562 (e.g., away from the PCB 524) in a manner (substantially) parallel to the optical axis X so as to define a respective inner radial wall 578 and an outer radial wall 580, each of which extends in a manner (substantially) parallel to the optical axis X, and an outer end wall 582 extending in a manner (substantially) orthogonal (perpendicular) to the optical axis X. The flange 576 is recessed relative to the aperture 568 (e.g., relative to the optical axis X) and is radially spaced outwardly therefrom so as to define a (first) receiving portion 584 configured to receive the cover glass 556. More specifically, when assembling ISLA 502, cover glass 556 is positioned adjacent to (e.g., in contact with) the inner radial wall 578 of flange 576, whereby cover glass 556 is nested within inner module 558 (e.g., receiving portion 584) and covers image sensor 342, such that cover glass 556 is axially spaced apart from image sensor 342 along optical axis X.
[0104] The outer ring 566 is defined by a (substantially) annular (second) flange 586 extending axially inwardly from the base 562 (e.g., toward the PCB 524) in a manner (substantially) parallel to the optical axis X and the flange 576 so as to define a respective inner radial wall 588 and an outer radial wall 590, each of which extends in a manner (substantially) parallel to the optical axis X, and an inner end wall 592 extending in a manner (substantially) orthogonal (perpendicular) to the optical axis X. The flange 586 is recessed relative to the outer radial wall 574 of the base 562 and is radially inwardly spaced from the outer radial wall 574 of the base 562 so as to define a (second) receiving portion 594 and a recess 596. The receiving portion 594 is configured to (partially) receive the outer module 560, so that the base 562 covers the outer module 560, and the recess 596 is configured to contain (receive, accommodate) the image sensor 342, so that the outer ring 566 surrounds the image sensor 342. Figure 7 As shown, when ISLA 02 is assembled, the inner end wall 592 defined by the flange 586 is positioned adjacent to (eg, in contact with) the PCB 524 radially inward of the channel 532 .
[0105] The outer module 560 includes a body 598 and teeth 600. As described in further detail below, the outer module 560 is positioned around (e.g., surrounds) the inner module 558, and thus around the image sensor 342, and supports assembly of the ISLA 502 by providing sufficient surface area to establish the interfaces 540, 542.
[0106] The body 598 defines respective inner and outer end walls 602, 604, each of which extends in a manner (substantially) orthogonal (perpendicular) to the optical axis X, and respective inner and outer radial walls 606, 608, each of which extends in a manner (substantially) parallel to the optical axis X. The inner and outer end walls 602, 604 define respective inner and outer mounting surfaces 610, 612 that support the application of adhesives 544, 548, respectively. More specifically, the inner mounting surface 610 faces (is oriented toward) the PCB 524 and supports the application of adhesive 548 to define the interface 542, and the outer mounting surface 612 faces (is oriented toward) the inner mounting surface 516 defined by the inner end 514 of the lens holder 504 and supports the application of adhesive 544 to define the interface 540. Figure 7 As shown, when ISLA 502 is assembled, inner radial wall 606 of body 598 is positioned adjacent to (eg, in contact with) outer radial wall 574 of base 562 , and outer radial wall 608 of body 598 is (substantially) aligned with outer radial wall 520 of lens holder 504 .
[0107] The lens holder 504, the cover glass holder 526 and the PCB 524 are arranged axially in an end-to-end stacked configuration along the optical axis X, whereby the mounting surfaces 516, 612, 610, 534 extend in a (substantially) parallel manner to each other and in a (substantially) orthogonal (perpendicular) manner to the optical axis X, wherein the mounting surfaces 516, 612 and the mounting surfaces 610, 534 are oriented in a facing relationship. The stacked configuration of the ISLA 502 and the resulting (substantially) orthogonal (perpendicular) orientation of the mounting surfaces 516, 612, 610, 534 relative to the optical axis X eliminate radial abutment of the lens holder 504, the cover glass holder 526 and the PCB 524, as in known ISLAs, thereby eliminating radial clearance that may be required for (adhesive) fixing (connecting) components of the ISLA 502, thereby reducing the overall radial dimension R of the ISLA 502. For example, in the illustrated embodiment, ISLA 502 is configured such that radial dimension R is (substantially) within the range of (approximately) 13.8 mm to (approximately) 15.7 mm, which is a (approximately) 7% reduction compared to known ISLAs. Additionally, the stacked configuration of ISLA 502 described herein not only increases the amount of internal space available for fasteners, electrical connectors, light pipes, indicators, wiring, surface mounts, sensors, etc. (e.g., on the outer surface 530 of PCB 524), but also increases the accessibility of mounting surfaces 516, 612, which facilitates stencil (screen) printing of adhesive 544 rather than dispensing via a needle (or other such device) as is typically done during assembly of an ISLA.
[0108] Continue to refer Figure 7 , the body 598 is configured to be inserted into (received by) the channel 532 so that the outer module 560 is nested within the PCB 524. The nesting of the outer module 560 and the PCB 524 not only supports the assembly of the ISLA 502, but also inhibits (if not completely prevents) undesired (radial) movement between the cover glass holder 526 and the PCB 524 (e.g., during the curing of the adhesives 544, 548). More specifically, the nesting of the outer module 560 and the PCB 524 facilitates the proper alignment of the cover glass holder 526 with the PCB 524, the image sensor 342, and the lens holder 504, thereby facilitating the optical group 508 ( Figure 5 , Figure 6 ) with the image sensor 342. The nesting of the outer module 560 and the PCB 524 also inhibits (if not completely prevents) undesired (radial) movement between the cover glass holder 526 and the PCB 524, thereby increasing the uniformity of the curing of the joints 546, 550 so as to mitigate any misalignment that may occur between the optical stack 508 and the image sensor 342.
[0109] The tooth 600 extends radially inward from the body 598 (e.g., toward the inner module 558), is recessed along the optical axis X relative to the inner end wall 602 and the outer end wall 604 of the body 598 and is axially spaced therefrom so as to define corresponding inner end walls 614 and outer end walls 616 and an inner radial wall 618 that extend in a manner that is (substantially) orthogonal (perpendicular) to the optical axis X and the inner radial wall 618 that extends in a manner that is (substantially) parallel to the optical axis X. More specifically, the teeth 600 are axially spaced from the inner end wall 602 of the body 598 to define a gap 620 that receives the body 598 within the channel 532 in the PCB 524, and the teeth 600 are axially spaced from the outer end wall 604 of the body 598 to define a receiving portion 622 that is configured to (partially) receive the inner module 558 so that the inner module 558 is nested within the outer module 560. Figure 7 As shown, when the ISLA 502 is assembled, the inner end wall 614 of the tooth 600 is positioned adjacent to (e.g., in contact with) the PCB 524, the outer end wall 616 of the tooth 600 is positioned adjacent to (e.g., in contact with) the inner end wall 570 of the base 562 of the inner module 558, and the inner radial wall 618 of the tooth 600 is positioned adjacent to (e.g., in contact with) the outer radial wall 590 of the flange 586.
[0110] As indicated above, it is contemplated that the inner module 558 and the outer module 560 may be secured (connected) together in any suitable manner. In the illustrated embodiment, the modules 558, 560 are connected by applying an adhesive (not shown) therebetween, which adhesive may be the same adhesive 548 used to secure (connect) the inner end 536 of the cover glass holder 526 to the outer face 530 of the PCB 524. More specifically, the adhesive is applied to the interface between the outer radial wall 590 and the inner radial wall 618, to the interface between the inner end wall 570 and the outer end wall 616, and / or to the interface between the outer radial wall 574 and the inner radial wall 606.
[0111] like Figure 7 As shown, outer module 560 defines a radial dimension Rm (e.g., width) that is (substantially) in the range of (approximately) 1 mm to (approximately) 2 mm, as compared to known ISLAs that typically define a corresponding radial dimension that is (substantially) in the range of (approximately) .25 mm to (approximately) .5 mm, which not only increases the surface area available for adhesives 544, 548, but also increases the structural support provided by cover glass holder 526. As such, cover glass holder 526 serves as a structural component of ISLA 502 that increases its overall strength and stability, as compared to optical modules used in known image capture devices.
[0112] Furthermore, reference Figure 5 and Figure 6 , electrical connector 512 is supported by (connected to) PCB 524 and is spaced (placed, positioned) radially outward (e.g., relative to optical axis X) from cover glass holder 526. More specifically, electrical connector 512 is (substantially) aligned with interface 542 (e.g., connector 550) and is axially spaced from interface 540 (e.g., connector 546) along optical axis X, which facilitates access to (e.g., direct viewing of) interface 540 during UV curing, as described in further detail below. Electrical connector 512 can be any component (or array of components) that supports the functionality of ISLA 502 and / or an image capture device (e.g., image capture device 200, 300), including, for example, one or more connectors, ports, hubs, interfaces, surface mounts, etc., and can be connected to PCB 524 in any suitable manner. For example, it is contemplated that the electrical connector 512 may be adhesively secured (connected) to the PCB 524 and / or the electrical connector 512 may be mechanically secured (connected) to the PCB 524 (eg, via one or more mechanical fasteners).
[0113] Continue to refer Figures 5 to 7 , the assembly method of ISLA 502 will be discussed.
[0114] Initially, the cover glass holder 526 is assembled by connecting (adhesively) the inner module 558 and the outer module 560.
[0115] The electrical connector 512 can then be connected to the PCB 524, after which the lens holder 504 is actively aligned with the assembled cover glass holder 526. The active alignment of the lens holder 504 and the cover glass holder 526 results in a corresponding active alignment of the optical group 508 and the image sensor 342 so as to optimize their alignment. More specifically, during the active alignment process, the adhesive 544 is applied to the outer mounting surface 612 defined by the outer module 560 and / or the inner mounting surface 516 defined by the lens holder 504. Then, a first device (e.g., a robotic assembly) is used to position and align the lens holder 504 and the cover glass holder 526, after which the adhesive 544 is subjected to a UV and thermal curing process to form a joint 546, thereby fixing the connection between the lens holder 504 and the cover glass holder 526, which is facilitated by the relative positions of the interface 540 and the electrical connector 512. More specifically, due to the axial misalignment (separation) between the electrical connector 512 and the interface 540 along the optical axis X, a direct line of sight can be established between the interface 540 and the UV curing device (equipment) 700. The direct line of sight between the interface 540 and the UV curing device 700 suppresses (if not completely prevents) interference with the curing process that may be caused by the electrical connector 512 (e.g., shielding of UV light projected on the interface 540), thereby increasing the uniformity of the curing of the joint 546 and suppressing (if not completely eliminating) shrinkage of the adhesive 544 and misalignment between the optical group 508 and the image sensor 342.
[0116] Before or after forming joint 546, adhesive 548 is applied to the outer mounting surface 534 defined by PCB 524 and / or the inner mounting surface 610 defined by outer module 560 to connect cover glass holder 526 to PCB 524, which can be performed in a conventional manner rather than via the aforementioned active alignment process. Adhesive 548 is then allowed to cure to form joint 550.
[0117] Now, refer to Fig. 9 and Fig.10 , an alternative embodiment of ISLA 502 identified by reference numeral 802 will be discussed. More specifically, Fig. 9 is an axial (longitudinal) cross-sectional view of ISLA 802, Fig.10 yes Fig. 9 802 includes features similar to those of the aforementioned ISLA 502, and therefore, for the sake of brevity, only the differences will be discussed. Thus, the same reference numerals will be used to refer to elements, structures, features, etc. common to ISLA 502 and 802.
[0118] ISLA 802 includes the lens holder (mount) 504, lens barrel 506, and electrical connector 512 discussed above in conjunction with ISLA 502 and an alternative embodiment of a PCB subassembly 510 identified by reference numeral 810. PCB subassembly 810 includes the aforementioned PCB 524 and an alternative embodiment of a cover glass holder 526, which is identified by reference numeral 826 and includes corresponding inner modules (components) 858 and outer modules (components) 860. Cover glass holder 826 includes similar features to the aforementioned cover glass holder 526, and therefore, for the sake of brevity, only the differences from cover glass holder 526 will be discussed. As such, the same reference numerals will be used to refer to elements, structures, features, etc. common to cover glass holders 526, 826.
[0119] The inner module 858 includes the base 562, inner ring 564, and outer ring 566 discussed above in conjunction with the aforementioned coverslip holder 526. However, in contrast to the aforementioned coverslip holder 526, the outer ring 566 (e.g., flange 586) is positioned adjacent to (e.g., extends from) the outer radial wall 574 of the base 562.
[0120] The outer module 860 includes the body 598 and teeth 600 discussed above in conjunction with the aforementioned coverslip holder 526. However, in contrast to the aforementioned coverslip holder 526, the teeth 600 are positioned adjacent to the outer end wall 604 of the body 598 (e.g., extending radially inwardly from the outer end wall 604) so as to define a receiving portion 822, which is configured to (partially) receive the inner module 858 so that the inner module 858 is nested within the outer module 860. More specifically, the teeth 600 are configured so that the outer end wall 604 of the body 598 and the outer end wall 616 of the teeth 600 are (substantially) aligned along the optical axis X (e.g., so that the outer end walls 604, 616 are arranged in a (substantially) co-linear manner). As shown in FIG. Fig.10 As shown, when the ISLA 802 is assembled, the body 598 is positioned adjacent to (e.g., in contact with) the flange 586 on the inner module 858, and the inner end wall 614 of the tooth 600 is positioned adjacent to (e.g., in contact with) the base 562 of the inner module 558, so that the outer module 860 (e.g., the tooth 600) covers the inner module 858 (e.g., the base 562 and the flange 586).
[0121] As discussed above in conjunction with the aforementioned coverslip holder 526, it should be contemplated that the inner module 858 and the outer module 860 can be secured (connected) together in any suitable manner, for example, via an adhesive applied to the interface between the body 598 of the outer module 860 and the flange 586 on the inner module 558, the interface between the inner end wall 614 of the tooth 600 and the flange 586, and / or the interface between the inner end wall 614 of the tooth 600 and the outer end wall 572 of the base 562.
[0122] Now, refer to Fig.11 , another embodiment of ISLA 502 identified by reference numeral 902 will be discussed. More specifically, Fig.11 902. ISLA 902 includes similar features to the aforementioned ISLA 502, 802, and thus, for the sake of brevity, only the differences will be discussed. As such, the same reference numerals will be used to refer to elements, structures, features, etc. common to ISLA 502, 802, 902.
[0123] In addition to the lens barrel 506, the electrical connector 512, and the PCB subassembly 510, the ISLA 902 also includes an alternative embodiment of the lens holder 504 identified by the reference numeral 904. The lens holder 904 includes similar features to the aforementioned lens holder 504, and thus, for the sake of brevity, only the differences will be discussed. As such, the same reference numerals will be used to refer to elements, structures, features, etc. common to the lens holders 504, 904.
[0124] The lens holder 904 includes respective inner modules (components) 906 and outer modules (components) 908 , which are connected together and configured as discrete components of the lens holder 904 .
[0125] The inner module 906 includes an inner end 910 and an outer end 912. The inner end 910 of the inner module 906 defines a (substantially) U-shaped chamber 914 that is configured to receive the cover glass holder 526 and the cover glass 556, such that the inner module 906 is positioned around (e.g., surrounds) the image sensor 342 and the inner mounting surface 916, and the outer end 912 defines an outer mounting surface 918.
[0126] The outer module 908 includes an inner end 920 defining an inner mounting surface 922 and an outer end 924. Additionally, the outer module 908 defines an interior chamber 522 that receives the lens barrel 506, as discussed above in conjunction with the lens holder 504 described above.
[0127] The inner module 906 is fixed (connected) to the outer module 908 and the PCB 524 at respective first and second interfaces 926, 928. Thus, the inner module 906 is placed between the outer module 908 and the PCB 524 and indirectly connects the outer module 908 and the PCB 524, such that the outer module 908 and the PCB 524 are axially spaced from each other along the optical axis X and without any direct connection. More specifically, the inner end 920 of the outer module 908 is fixed (connected) to the outer end 912 of the inner module 906 by the adhesive 544 so as to define a (first) joint 930, which has been subjected to the aforementioned UV and heat curing process discussed above in conjunction with the ISLA 502, and the inner end 910 of the inner module 906 is fixed (connected) to the outer surface 530 of the PCB 524 by the adhesive 548 so as to define a (second) joint 932. Thus, the modules 906, 908 of the lens holder 904 are arranged axially in an end-to-end, stacked configuration along the optical axis X, whereby the mounting surfaces 916, 918, 922 are oriented in a manner that is (substantially) parallel to each other and in a manner that is (substantially) orthogonal (perpendicular) to the optical axis X.
