## Title
Enabling the integration of a three hundred and sixty degree panoramic camera within a consumer device case

## Abstract

A user activation of an image capture function of a consumer electronic device is received. The image capture function is for a surround image mode. Two or more camera lenses of a consumer electronic device case are approximately concurrently activated. Responsive to activating the lenses, a front-side image from a first camera lens and a rear-side image from a second camera lens are optically captured. Content from the front-side image and content from the rear-side are recorded in a non-transitory storage medium of the mobile device within a single file for a surround mode image.

## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is a continuation of U.S. patent application Ser. No. 14/092,393, filed on Nov. 27, 2013 of which is incorporated herein in its entirety.


BACKGROUND
The present invention relates to the field of imaging and, more particularly, to a enabling the integration of a three hundred and sixty degree panoramic camera within a consumer electronic device case.
Increasingly, camera equipped mobile devices like portable computing tablets are replacing formerly discrete devices, such as still and video cameras. Consumers have begun to demand additional functionality from these devices (or from digital cameras). For example, cameras able to record depth for 3D and 4D imagining have begun to emerge. Similarly, panoramic modes for image capture are becoming an increasingly popular feature of many modern consumer device operating systems.
Conventional panoramic capture modes require successive movements of a device with a single activated lens. The movement permits different fields of view to be captured at different points in time, which can be stitched together into a panoramic view. Using conventional techniques, capturing scenes in this manner can be time consuming, and dynamic movement within the scenes (causing discrepancies in the time spaced images) can be problematic.
Another conventional panoramic technique is to utilize a single ultra-wide angle lens to capture a panoramic scene. This ultra-wide angle lenses may result in significant distortion, but the convenience of capturing a scene without time spacing images, outweighs these negatives to many users and manufactures. Some panoramic lenses are optical peripherals attachable to a mobile device, such as a tablet) to bend incoming light (using a fish-eye lens for example) before it enters the camera's internal optical components.
One solution such as clip on adapters which permit panoramic capabilities can cause the consumer electronic device to be cumbersome and weighty. Further, the solutions often only provide limited field of view which can result in the omission of critical imagery. Additionally, many adapters force users to orient devices in non-standard orientations (e.g., flat) which can block users from seeing a live preview of a panoramic camera.

FIG. 2 is a schematic diagram illustrating a system 200 for enabling the integration of a three hundred and sixty degree panoramic camera within a consumer electronic device case in accordance with an embodiment of the inventive arrangements disclosed herein.
In system 200, consumer electronic device 210 can be communicatively linked and/or coupled to case 212. Case 212 can include, but is not limited to, panoramic camera 214, a flash, and the like.
The lenses 216 each represent an optical lens or assembly of lenses used to make images of object for storage on storage medium 224. Each lens 216 has a set of fundamental parameters associated, which include focal length and aperture. Each lens 216 may also be associated with image stabilizing components and pixel density. Lenses (216) can include, but is not limited to, wide-angle lenses, ultra-wide angle, apochromatic (APO) lens, a process lens, an enlarger lens, a fisheye lens, a stereoscopic lens, a soft focus lens, an infrared lens, an ultraviolent lens, a swivel lens, or a perspective control lens.
The flash of case 212 (not shown) is a component that produces a flash of artificial light (typically for 1/1000 to 1/200 of a second) at a color temperature of about 5500 K to help illuminate a scene. The flash may include a high capacity capacitor chargeable to several hundred volts. Flash can be an air-gap flash, a multi flash component (using multiple flashes to find depth edges or to create a stylized image), a high-current flash LED and the like. In one embodiment, the flash can be an omnidirectional one, which illuminates a front and a back side of the camera 214 (thus permitting front and rear lenses to capture an illuminated scene). The flash may be stationary relative to the device 210 and/or case, or may expend and retract within a body of the device case. In one embodiment, the flash of device 210 may be an assembly of two or more discrete components, such as a front facing flash and a rear facing flash which can be utilized by case 212 during operation.
The consumer electronic device 210 may be a stand-alone device, where all the surround mode imagery functionality is implemented internal to the consumer electronic device 210 and/or within case 212. In another embodiment, the consumer electronic device 210 may be a network 270 connected one, where one or more of the surround mode imagery functions are performed remotely, such as by an image processing server 280. Consumer electronic device 210 may be a mobile communication device able facilitating user communications with one or more remote end-user devices 282. These communications can include the transmission and exchange of surround mode images. For example, end user device may use text messaging (with attachment), video conferencing (streaming video/images captured from imaging component 232), email image conveyances, image file synchronization sharing, and other technologies to provide end user device 282 with imagery from camera 214.
Consumer electronic device 210 includes hardware 220 and software/firmware 250. Not all the elements shown in the hardware 220 and software/firmware 250 need be present for each implementation of the disclosure, and some implementations will include additional (not shown) components. The hardware 220 includes one or more processors 222, a storage medium, a transceiver 226, a display 228, a battery 230 (or other power source), imaging components 232, and the like. The processor 222 can be a central processing unit (CPU) or a microprocessor. Processor 222 carries out instructions of a computer program by performing arithmetical, logical, and input/output operations of a system. The processor 222 can be a single core or multi-core processor. Storage medium 222 can be a non-transitory storage medium, which refers to a medium that is not a carrier wave. Storage medium 222 stores or records information. Storage medium 222 can use magnetic storage, optical storage, electrical storage technologies, and the like.
Transceiver 226 is a component able to transmit and receive information to and from the consumer electronic device 210 and/or case 212. Transceiver 226 communicatively links device 210 to network 270, where the communication link may be a wired or wireless link.
Battery 230 is a power source that provides electronic energy to electronics of the consumer electronic device 210 and/or case 212. The battery 230 is often a chemical battery consisting of one or more electrochemical cells that convert stored chemical energy into electrical energy. Battery 230 may be rechargeable.
In one embodiment, imaging components 232 can be a communicatively linked hardware/software entity. Imaging components 232 are components able to capture images and store those images onto storage medium 224. In one embodiment, the imaging components 232 are digital ones, which include image sensor 234, lenses 236, flash 238, sensors 240, and the like. The image sensors, typically charge-coupled device (CCD) or complementary metal-oxide-semiconductor (CMOS) sensor chips, turn light into discrete signals.
The sensors 240 include any of a variety of sensors used in photography. These sensors 240 can, for example, detect movement of the device 210, which is especially useful when taking time-spaced images (see step 134). Sensors 240 may include an accelerometer, a tilt sensor, a gyroscope, a global positioning system (GPS) element, a compass, a barometer, an altimeter, and the like.
The software/firmware 250 may include one or more of an image capture module 252, an image timing module 254, an image combiner 256, an optic control module 258, a digital imaging processor (DIP) module 260, a user interface module 262, and the like. In one instance, software/firmware 250 can include user applications, system applications, an operating system, and the like.
The image capture module 252 may capture images from multiple lenses facing substantially different directions. For example, the software/firmware of module 252 may capture images substantially concurrently from a front facing camera lens and a rear facing camera lens of a consumer electronic device.
The image timing module 254 module controls a timing of images from multiple different lens(es) 236. In one embodiment, the image timing module 254 can synchronize image capture times from a front facing lens and from a rear facing lens. Video from multiple different (and differently facing) lenses can also be timed. In one embodiment, the timing can be intentionally staggered and/or unified with a sensor (such as a tilt sensor or accelerometer) to take pictures after the device 210 have moved so that the lens(es) 236 cover a different field of view than what is covered in an initial image capture. Super-pixilation (from multiple different images at different times with slightly different angles) can be achieved in one embodiment, by suitable adjustments of the image timing module 254.
The image combiner 256 module combines content from multiple different lenses. The combiner 256 can stitch together images with common or overlapping regions. The image combiner 256 can create images including depth (3D and 4D images), in contemplated embodiments. The image combiner 256 may adjust lighting, contrast, and other image characteristics to optimize them, by combining images taken from different lens(se) 236.
The optic control module 258 controls optical components of the system. Focus, focal length, zoom, flash, angle, and the like are all able to be controlled by program instructions of the optic control module 258 being executed by processor 222.
The digital imaging processor (DIP) module 260 uses computer algorithms to perform image processing on digital images. The DIP module 260 can perform utilize technologies for pixilation, linear filtering, principal components analysis, independent component analysis, Hidden Markov models, anisotropic diffusion, partial differential equations, self-organizing maps, neural networks, wavelets, and the like. Additional DIP processing may occur in image processing server 280 in one embodiment.
User interface 262 can be a human-to-machine interface for the consumer electronic device 210. The user interface may interact through a touch screen display (228), to a set of one or more physical buttons that may exist within the hardware 220, to wirelessly connected peripherals that receive user input and/or produce output, and the like. The user interface 262 permits the user to take pictures, video, and sound recordings using the consumer electronic device 210. The user interface 262 also permits control of hardware/software functions related to imagery and to establish and change user configuration preferences.
FIG. 3 is a schematic diagram illustrating a method 300 for enabling the integration of a three hundred and sixty degree panoramic camera within a consumer electronic device case in accordance with an embodiment of the inventive arrangements disclosed herein.
In step 310, a consumer electronic device case with an embedded panoramic camera can be coupled to a consumer electronic device. A user may activate a consumer electronic device case camera function in a surround image mode, as shown by step 320. In step 322, two or more lenses of the consumer electronic device case are initiated to cover an area on both side of the consumer electronic device. Initiating the lenses can take them from a minimal (or no power) state to an active one. In surround image mode, the total captured area of the multiple lenses is greater than one hundred and eighty degrees and may or may not be a continuous overlapping capture area.
In step 324, a display of the camera may provide feedback to a user showing image content from one or more lenses of the camera embedded within the case. The feedback can be displayed, for example, on a user interface (e.g., 310) shown on a touch screen (e.g., embodiment 190). In step 326, a set of pre-image capture device adjustments can occur. These adjustments may include focusing the lens, zooming the lens, repositioning and/or powering up a flash component (e.g., charging the capacitor), and the like. In step 328, a specialized flash (referred to as a surround flash) can be triggered as necessary/appropriate before image(s) are captured. The surround flash may illuminate an environment on both sides of a consumer electronic device.
In step 330, the lenses themselves are active to capture images. This image capture occurs (from the multiple lenses) at approximately or substantially the same time. In step 332, the images that were captured are stored in a storage medium and integrated within a single surround image file. Alternatively, a folder (referred to as a surround image folder) including multiple images from different lenses may be created. Additionally, both a surround image file and surround image folder may be used in embodiments (i.e., the surround image folder stores a set of lens-specific raw images and the surround image file is created from these raw images).
The camera of the consumer electronic device case may or may not take a series of time spaced images when surround mode is activated. This novel function is an extension of conventional panoramic functions, where a single lens is used to create a panoramic image by moving the camera of the case or the consumer electronic device itself (and the capturing lens) to create a capture region greater than otherwise possible. If a camera of the consumer electronic device does take additional time spaced images, the process 300 can progress from step 334 to step 324. Once all (if any) time spaced images are taken, the process may progress from step 334 to step 336. In step 336, an in-camera processor (or a remote one assuming the raw images are conveyed over a network to a remote server) may use one or more internal digital signal processing (DSP) function(s) to process stored images. In step 138, a set of post-image capture device adjustments may occur. These adjustments can change the power state of optic components, of a flash, may adjust the user interface 110, and the like.
FIG. 4A-H is a schematic diagram illustrating a set of embodiments for enabling the integration of a three hundred and sixty degree panoramic camera within a consumer electronic device case in accordance with an embodiment of the inventive arrangements disclosed herein.
FIG. 4A-4H show different arrangements of lenses for a panoramic camera embedded within a case. Although the examples in FIG. 4A-4F assume a small optics board having lenses facing in different directions, one of ordinary skill can recognize that the shown lens arrangements can also apply for other positions. FIG. 4G shows a substantially opaque outer casing for a panoramic camera of a consumer electronic device case. FIG. 4H shows a substantially transparent outer casing for a panoramic camera of a consumer electronic device case.
FIG. 4A-4C show different side views of a dual facing panoramic camera of a consumer electronic device case. In FIG. 4A, one front facing lens 410 faces in an opposing direction to one rear facing lens 412. The lenses may have approximately equivalent or intentionally different imaging characteristics depending on implementation choices.
FIG. 4B shows two different lenses per side of a dual facing panoramic camera of a consumer electronic device case. These different lenses may be useful for different functions, and may have different optical characteristics. For example, one front facing 422 and one rear facing 424 lens may be normal lenses for standard pictures. The additional front facing 426 and rear facing 428 lenses may be ultra-wide lenses, which are able to capture a substantially greater field of view for a surround mode. The ultra-wide lenses may be subject to substantially more distortion than their counterparts 422, 424. Further, images can be captured using both the front facing 422, 426 and/or both the rear-facing 424, 428 lenses, which are able to be processed to achieve image results significantly better than is possible with a single lens alone. That is, the different optical characteristics of the lenses can be synergetic to produce a combined whole greater than either of the discrete parts. Use of two lenses facing in a common direction as shown by FIG. 4B can result in very flexible optics able to serve a gambit of functions.
FIG. 4C shows a series of five 430-438 different lenses, facing different angles about a curved surface of a panoramic camera base of a consumer electronic device case. The base may be a substrate into which the optical components are directly integrated. The base may also include additional components built on top a substantially flat substrate to produce fixed angles for the various lenses 430-438. As shown, a full overlapping field of view of greater than 270 degrees can be created from the five lenses 430-438. Software/firmware can be used to select which of the lenses 430-438 are to be used for which image capture functions of a mobile device.
FIG. 4D-4F show angled views of different lens arrangements. FIG. 4D represents a panoramic camera embedded within a consumer electronic device case, which has one lens 442 on the shown side. FIG. 4E represents a panoramic camera embedded within a consumer electronic device case having two lenses 444, 446 facing in the same direction. The single lens 442 may be on one side, and two lenses 444, 446 may be on an opposing side of the same panoramic camera. Alternatively, the panoramic camera can have the same number of lens per side (as shown by FIGS. 4A and 4B). Any number of lenses may appear on a single side of an image component, which are positioned in the same or different angles. For example, FIG. 4F shows four different lenses 448-454 on a single side of panoramic camera, which face at different angles relative to a substantially flat plane of that side of the panoramic camera. The sides of the camera may form substantially or approximately flat plains, or may be curved depending on implementation choices.
FIGS. 4G and 4H show an outer shell or segment 470 for a panoramic camera embedded within a consumer electronic device case consistent with corner segment 310. In FIG. 4G, a set of lenses 460-468 follow an outer curve of the segment 470. An additional front 472 and/or rear lens may be included in segment 470. The outer shell of FIG. 4G does not permit light to pass through in an optically significant fashion. Thus, either a portion of the lenses 460-468, 472) must physically extrude from the outer shell and/or the lenses 460-468, 472 can be inset into the shell 470 but a small transparent membrane can permit light to pass to the lenses 460-468, 472.
FIG. 4H shows a transparent outer shell for segment 486, which permits light to pass through to be captured by included lenses 480-484. The outer shell may be polarized/un-polarized and may have additional filters, which do not negatively affect an ability of the lenses 480-484 to capture light. A transparent outer shell permits light to pass through a variety of angles, which is highly beneficial for many surround image mode embodiments.
FIG. 5A-J is a schematic diagram illustrating a set of embodiments for enabling the integration of a three hundred and sixty degree panoramic camera within a consumer electronic device case in accordance with an embodiment of the inventive arrangements disclosed herein.
FIGS. 5G and 5H show embodiments where one or more lenses is stationary relative to a mounted surface (e.g., surface of a consumer electronic device case), which is connected by hinge 532. The surface can have a collapsed state 530, where the lenses are facing in approximately or substantially opposing directions. In a butterflied state 534, the surfaces can have a substantial angle between them, which results in lenses attached to the mounted surface capturing different content.
FIGS. 5I and 5J show another embodiment, where a surface mounts on a rotatable axle. The surface may have a first state 538, where an included set of lenses are in front and rear facing positions. The surface can rotate 544 about the axis, so that the included lenses are angled significantly.
Although many configurations for movable lenses are shown (FIG. 5D-5J) others are contemplated. For example, conventional pan, tilt, zoom (PTZ) mechanisms exist, which can be utilized herein. Additionally, instead of a track 522 along which a lens moves, a different track can be established to move the panoramic camera (e.g., 212).
Regardless of whether the lenses are fixed or movable, many different techniques exist for capturing images when operating in a surround mode. FIG. 5A-5C show an embodiment where two opposing lenses can capture 360 degree images in surround mode. As shown by FIG. 5A, a device positioned in an upward state 510 is able to capture front region 512 using a first facing lens and rear region 514 using a rear facing lens. While still in surround image mode, the device can be tilted sideways so it is in a sideward state 516. When so positioned, the front facing lens can capture region 518 and the rear facing lens can capture region 520. An accelerometer or other sensor (sensors 240) can detect this movement in one embodiment. Regions 512 and 514 can be captured at substantially a first point in time, and regions 518 and 520 can be captured at substantially a second point in time. The overall captured regions are shown in FIG. 5C, which assumes a stable pivot position of the imaging component. The regions 512-520 as shown in FIG. 5C substantially overlap, so that using images captured at two points in time, a surround region is captured.
Embodiments having actuator-associated lenses capable of movement can utilize a similar technique, where a first image is captured when a lens is in a first position (like state 524) and a second image is captured when a lens is in a second position (like state 526). Thus, different regions, which overlap in a surround mode (as shown in FIG. 5C, for example) can result from a mobile device maintained in a relatively stable position, in which image capture lenses move.
Unlike prior art, where a single lens is moved multiple times to join images into a panorama, using multiple lenses facing different directions (even when movement occurs) is less sensitive to motions in a captured scene. For example, a full three sixty degree region is captured using two time-spaced images (FIG. 5C) per the disclosure, where an equivalent using a single lens would require additional movements and image captures. Dynamic objects will likely be moving in a scene during these time periods, which greatly confounds problems with image stitching. Minimizing the movement (by using multiple lenses facing in different directions) either totally eliminates dynamic movement problems (in embodiments where images are captured at a single point in time) or significantly alleviates the problem (when multiple lenses facing different directions take images at two or more times) with dynamic artifacts.
The flowchart and block diagrams in the FIGS. 1-5J illustrate the architecture, functionality, and operation of possible implementations of systems, methods and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts, or combinations of special purpose hardware and computer instructions.
