The image stabilizer 240 may move the image sensor 230 or at least one lens included in the lens assembly 210 in a particular direction, or control an operational attribute (e.g., adjust the read-out timing) of the image sensor 230 in response to the movement of the camera module 180 or the electronic device 101 including the camera module 180. This allows compensating for at least part of a negative effect (e.g., image blurring) by the movement on an image being captured. The image stabilizer 240 may sense such a movement by the camera module 180 or the electronic device 101 using a gyro sensor or an acceleration sensor disposed inside or outside the camera module 180. The image stabilizer 240 may be implemented, for example, as an optical image stabilizer.
The memory 250 may store, at least temporarily, at least part of an image obtained via the image sensor 230 for a subsequent image processing task. For example, if image capturing is delayed due to shutter lag or multiple images are quickly captured, a raw image obtained (e.g., a Bayer-patterned image, a high-resolution image) may be stored in the memory 250, and its corresponding copy image (e.g., a low-resolution image) may be previewed via the display device 160. Thereafter, if a specified condition is met (e.g., by a user's input or system command), at least part of the raw image stored in the memory 250 may be obtained and processed, for example, by the image signal processor 260. According to an embodiment, the memory 250 may be configured as at least part of the memory 130 or as a separate memory that is operated independently from the memory 130.
The image signal processor 260 may perform one or more image processing with respect to an image obtained via the image sensor 230 or an image stored in the memory 250. The one or more image processing may include, for example, depth map generation, three-dimensional (3D) modeling, panorama generation, feature point extraction, image synthesizing, or image compensation (e.g., noise reduction, resolution adjustment, brightness adjustment, blurring, sharpening, or softening). Additionally or alternatively, the image signal processor 260 may perform control (e.g., exposure time control or read-out timing control) with respect to at least one (e.g., the image sensor 230) of the components included in the camera module 180. An image processed by the image signal processor 260 may be stored back in the memory 250 for further processing, or may be provided to an external component (e.g., the memory 130, the display device 160, the electronic device 102, the electronic device 104, or the server 108) outside the camera module 180. According to an embodiment, the image signal processor 260 may be configured as at least part of the processor 120, or as a separate processor that is operated independently from the processor 120. If the image signal processor 260 is configured as a separate processor from the processor 120, at least one image processed by the image signal processor 260 may be displayed, by the processor 120, via the display device 160 as it is or after being further processed.
According to an embodiment, the electronic device 101 may include a plurality of camera modules 180 having different attributes or functions. In such a 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.

The raw image 231 provided from the image sensor 230 may be transmitted to the external electronic device 201 separately from the small raw image 232. Since the raw image 231 is larger in capacity than the small raw image 232, the small raw image 232 may first be transmitted to the external electronic device 201, and thereafter the raw image 231 may be transmitted to the external electronic device 201. For example, the small raw image 232 may be transmitted to the external electronic device 201 while the ISP 260 performs correction on the raw image 231. The raw image 231 may be uploaded to the external electronic device 201 in an intact manner as generated by the image sensor 230, or a pre-processed image subjected to lens distortion compensation or noise cancellation may be updated.

The ISP 204 of external electronic device 201 may correct the received raw image 231. The external electronic device 201 may use the correction region information 203 previously generated to correct the raw image 231, or may correct the raw image 231 by using extended correction region information. The raw image 231 may have a higher quality than the small raw image 232. Accordingly, the ISP 204 of the external electronic device 201 may acquire more specific extended correction region information from a high quality image. The ISP 204 may use the previously generated correction region information and the raw image 231 together to generate the extended correction region information. The ISP 204 may use the extended correction region information to correct the raw image 231, thereby acquiring the high quality image 205. The high quality image 205 may be stored in the storage 206 of the external electronic device 201, and may be downloaded to the electronic device 101.

According to an embodiment, the processor 120 may select an object of interest by considering any one of the elements for selecting the object of interest. For example, the processor 120 may select only external objects which have a detection speed greater than or equal to a threshold speed based on a detection speed of the external objects. The detection speed may be a movement speed of an external object detected through the raw images. In addition, the processor 120 may detect a movement of the external objects and select an external object of which a detected movement is less than or equal to a threshold value as the object of interest.
Additionally, the processor 120 may select the object of interest by considering one or more of the elements for selecting the object of interest. For example, the processor 120 may select an object A as the object of interest based on the detection speed of the external objects, or may select an object B as the object of interest based on the user preference.
The processor 120 may select objects of interest by considering an image processing time. For example, when the plurality of external objects correspond to the object of interest, the processor 120 may select only some of the plurality of external objects as the objects of interest by considering that the image processing time will be delayed. The processor 120 may not select an external object which requires a long time for image processing. The processor 120 may select an external object which requires a short time for image processing as the object of interest. According to an embodiment, a priority for a partial region based on the element for selecting the object of interest may imply a priority for processing at least one object of interest.
The processor 120 may determine the priority by preferentially considering at least one or more of the elements to be selected as objects of interest. For example, the processor 120 may preferentially consider a detection speed of an object over (e.g., with a higher priority) the user preference, and may set a priority of an object A selected as the object of interest based on the detection speed to be higher than a priority of an object B selected as the object of interest based on the user preference.
According to an embodiment, when the object of interest is selected based on any one of the elements to be selected as the object of interest, the processor 120 may determine the priority according to a value corresponding to the one element. For example, the processor 120 may select objects C and D having a higher detection speed than a threshold speed, and may set a priority of the object C to have a higher detection speed than the priority of object D.
In operation 407, the electronic device 301 transmits data corresponding to at least a partial region to the external electronic device 302 according to a priority so that the external electronic device 302 generates image processing information for at least the partial region. For example, the processor 120 may sequentially transmit a plurality of pieces of data corresponding to the partial region according to a determined priority to the external electronic device 302 via the communication module 190 of
According to an embodiment, the processor 120 may determine a transmission order of data corresponding to one or more partial regions based on a communication environment with respect to the external electronic device 302. When a data transmission speed is decreased according to the communication environment of the external electronic device 302, the processor 120 may first transmit data corresponding to a partial region having a small amount of data.
In operation 409, the electronic device 301 uses image processing information to display an improved image including at least a partial region sequentially corrected according to a priority. For example, the processor 120 may sequentially correct a plurality of partial regions, and may display, on the display device 160, an improved image with partial regions are corrected.
According to an embodiment, the electronic device 301 may receive additional image processing information corresponding to a different partial region (e.g., a first partial region) among a plurality of regions while displaying the improved image. The electronic device 301 may correct the different partial region of a raw image by using the additional image processing information. In addition, the electronic device 301 may display an additional improved image with a different partial region (e.g., a second partial region) as additionally corrected. For example, the electronic device 301 may display an improved image of which a partial region corresponding to a low priority is corrected, and thereafter may display an additional improved image of which a partial region corresponding to a very next priority is corrected. The electronic device 301 may sequentially correct a plurality of partial regions based on one or more priorities, and may sequentially display additional improved images of which a plurality of partial regions are sequentially corrected.

In operation 507, the electronic device 301 determines if additional correction is detected. For example, the processor 120 may detect correction for a different partial region among a plurality of regions while displaying the improved image. The different partial region may be a region which is not yet subjected to image processing and which corresponds to a low priority.
If no additional correction is detected the electronic device 301 returns to the previous procedure and may display the improved image. Alternatively, the electronic device 301 may end the operation of displaying the improved image.
If additional correction is detected, proceeding to operation 509, the electronic device 301 displays an additional improved image. For example, the processor 120 may replace the improved image currently being displayed with the additional improved image, and may display the additional improved image through an image application. Alternatively, the processor 120 may display the additional improved image together with the improved image.
According to an embodiment, the electronic device 301 may repeatedly perform operations 507 and 509. For example, the electronic device 301 may display an additional improved image of which a partial region corresponding to a low priority is corrected, or may replace the additional improved image currently being displayed with an additional improved image of which a partial region corresponding to a very next priority is corrected.
An operation of acquiring a final image having improved image quality from a raw image may include a preview operation in which a raw image temporarily acquired via a camera is being displayed via a display, an image processing operation of the acquired raw image in the external electronic device 201, and an image processing operation of the capture raw image in the electronic device 101. The preview operation may be an operation in which a user prepares for capturing an image by focusing a camera on external objects to be captured.
An operation of generating image processing information in preparation for the preview operation is described below in detail with reference to
Referring to
In operation 605, the electronic device 601 transmits data corresponding to at least a partial region of the raw image to an external electronic device 602.

In operation 607, the external electronic device 602 draws a virtual image based on data corresponding to the partial region. For example, the external electronic device 602 may draw the virtual image before the preview to generate image processing information for improving image quality of the partial region. The drawn virtual image may have a similarity with an object of interest corresponding to the partial region, and may have some differences.
In operation 609, the external electronic device 602 transmits the image processing information generated based on the data corresponding to the partial region. The image processing information may include the drawn virtual image. In addition, the image processing information may include at least one of auto exposure information, improved auto white balance information, improved auto focus information, improved object recognition information, and improved depth map information.
In operation 611, the electronic device 601 captures the raw image. For example, the processor 120 may detect a user's capture input by using the camera module 180, and may capture the raw image based on the detected capture input.
In operation 613, upon capturing the raw image, the electronic device 601 transmits capture information to the external electronic device 602. The capture information may include information on at least part of the acquired raw image upon capturing the raw image or may include information on a change of the raw image before and after capturing the raw image.

In operation 617, the electronic device 601 displays the improved image. The improved image may be an image of which a partial region corresponding to a high priority is corrected.
In operation 619, the external electronic device 602 generates additional image processing information. For example, the external electronic device may generate additional image processing information corresponding to a different partial region corresponding to a low priority. The external electronic device 602 may generate additional image processing information corresponding to a partial region which is not yet drawn and which corresponds to a low priority. The external electronic device 602 may generate the additional image processing information based on information on a change of the raw image before and after capturing the raw image. In addition, the external electronic device 602 may generate additional image processing information for correcting a partial region corresponding to a next lowest priority. For example, the external electronic device 602 may sequentially generate a plurality of pieces of additional image processing information according to the determined priority.
According to an embodiment, the external electronic device 602 may determine that image quality improvement is not required as a result of analyzing data corresponding to a different partial region, and may not generate additional image processing information. In this case, an operation of generating an additional improved image may be omitted, and an improved image of which a partial region corresponding to an object of interest is completely corrected may be stored as a final image.
In operation 621, the external electronic device 602 transmits additional image processing information to the electronic device 601. The additional image processing information may include an additional virtual image corresponding to a partial region which is not yet drawn and which corresponds to a low priority. For example, even after additional image processing information corresponding to a low priority is transmitted, the external electronic device 602 may transmit additional image processing information corresponding to a very next priority. For example, the external electronic device 602 may sequentially transmit a plurality of pieces of additional image processing information corresponding to respective priorities according to the determined priority.
In operation 623, the electronic device 601 combines an improved image and an additional virtual image. For example, the processor 120 may sequentially combine the improved image and the additional virtual image whenever the additional image processing information is received.
In operation 625, the electronic device 601 displays an additional improved image. For example, the processor 120 may sequentially display an additional improved image of which a partial region corresponding to each priority is corrected. After displaying an additional improved image of which a partial region corresponding to a low priority is corrected, the processor 120 may display an additional improved image of which a partial region corresponding to a very next priority is corrected. An additional improved image to be displayed next may be an image acquired through accumulated corrections of additional improved images previously displayed. Therefore, among the additional improved images sequentially displayed, a last displayed additional improved image may be an image having best image quality among the additional improved images.
In operation 627, upon determining that image quality improvement of the raw image is complete, the electronic device 601 stores a final image subjected to image quality improvement of the raw image. In addition, in operation 629, the external electronic device 602 associated with the electronic device 601 also receives the final image from the electronic device 601 and stores the received final image.
The external electronic device 602 may additionally improve image quality of the final image even after the final image is stored. The external electronic device 602 may transmit the final image of which image quality is additionally improved to the electronic device 601.
According to an embodiment, operation 605 of the electronic device 601 and operations 607 and 609 of the external electronic device 602 may be repeatedly performed. For example, the electronic device 601 may sequentially transmit data corresponding to a plurality of partial regions to the external electronic device 602 according to a priority, and the external electronic device 602 may transmit a plurality of pieces of image processing information respectively corresponding to the plurality of partial regions to the electronic device 601.
The electronic device 601 may transmit the entirety or part of the data corresponding to the plurality of partial regions before capturing the raw image to the external electronic device 602 by considering an image processing time. In a case of transmitting only part of the data corresponding to the plurality of partial regions before capturing the raw image, the electronic device 601 may sequentially or concurrently transmit data corresponding to not-transmitted partial regions to the external electronic device 602 after capturing the raw image.
According to an embodiment, the electronic device 601 and the external electronic device 602 may repeatedly perform operations 619 to 625. For example, the electronic device 601 may sequentially generate and display improved images by sequentially combining the raw image and the virtual image according to a plurality of pieces of image processing information.

The electronic device 601 may select at least one object of interest among one or more external objects. For example, the processor 120 may select an object of interest by considering only any one of the elements for selecting the object of interest. The processor 120 may select only external objects which have a detection speed greater than or equal to a threshold speed based on a detection speed of the external objects. If a detection speed of the first person object 802 and the second person object 803 is greater than or equal to a threshold speed among objects of
The processor 120 may select the object of interest by considering at least one or more of the elements for selecting the object of interest. For example, the processor 120 may select the first person object 802 and the second person object 803 as the object of interest based on the detection speed of the external objects, and may select the chair object 804 as the object of interest based on the user preference. Upon identifying information frequently captured by a user in a chair which is the same as or similar to the chair object 804 of
The processor 120 may select objects of interest by considering an image processing time. For example, when the plurality of external objects correspond to the object of interest, the processor 120 may select only some of the plurality of external objects as the objects of interest by considering that the image processing time will be delayed. Upon determining that the image processing time for the first person object 802, the second person object 803, and the chair object 804 will exceed a threshold time, the processor 120 may select only some but not all of the first person object 802, the second person object 803, and the chair object 804 as objects of interest.
An operation of transmitting data corresponding to a partial region before capturing the raw image 801 may be repeated several times. The number of repetitions may be equal to or less than the number of partial regions selected based on objects of interest.
Referring to
The electronic device 601 may transmit the entirety or part of at least a partial region corresponding to at least one object of interest to the external electronic device 602 entirely or partially before capturing the raw image 801. In a case of transmitting only part of the partial region, the electronic device 601 may transmit a partial region not yet transmitted to the external electronic device 602 after capturing the raw image 801. A transmission order of the partial regions may be based on a priority.
The electronic device 601 may combine the raw image 801 and the virtual image based on image processing information transmitted from the external electronic device 602. For example, the processor 120 may sequentially or concurrently combine the captured raw image 801 and the received virtual image based on the image processing information. A plurality of virtual images 801 may be received until the raw image 801 is captured, and the virtual images may be sequentially combined with the raw image 801 according to a reception order. Alternatively, the received plurality of virtual images and the raw image 801 may be combined concurrently.
In operation 705, the electronic device 601 displays an improved image by combining the raw image 801 and the virtual image. For example, the processor 120 may sequentially or concurrently acquire the improved image according to an order of receiving a plurality of virtual images.
The electronic device 601 may transmit to the external electronic device 602 a different partial region corresponding to a low priority among a plurality of regions after the capture event, and may acquire an additional improved image by receiving additional image processing information corresponding to a different partial region corresponding to a low priority.

In operation 903, the electronic device 601 determines whether a movement variation of the electronic device 601 exceeds a reference variation. For example, in response to the acquiring of the raw image 1001 in a preview operation, the processor 120 may detect a movement of the electronic device 601 via a sensor module or detect a difference between a plurality of raw images acquired in the preview operation or a level of a blurred image, and may compare the detected movement variation and the reference variation. Herein, the reference variation may be a situation in which a movement of the electronic device is significant and thus it is difficult to acquire an image which is in focus.
If the movement variation of the electronic device exceeds the reference variation, the electronic device 601 may monitor the movement variation of the electronic device until the movement variation of the electronic device becomes less than the reference variation. For example, when a change of the movement of the electronic device 601 is significant and thus it is difficult to focus the raw image 1001, the processor 120 may monitor the variation of the movement of the electronic device without having to perform a procedure of recognizing external objects. The electronic device 601 may perform operation 905 upon detecting that the movement variation of the electronic device becomes less than the reference variation during the monitoring.
On the other hand, if the movement variation of the electronic device is less than the reference variation, proceeding to operation 905, the electronic device 601 recognizes external objects. For example, the processor 120 may recognize a first person object 1002, a second person object 1003, a third person object 1004, a soccer ball object 1005, a goalpost object 1006, and a tree object 1007 from the acquired raw image 1001.
In operation 907, the electronic device 601 determines whether a movement variation of external objects exceeds a reference variation. For example, the processor 120 may determine whether there is an object of which a movement variation exceeds the reference variation among objects 1002 to 1007 recognized from the raw image 1001.
If the movement variation of the external objects exceeds the reference variation, the electronic device 601 may monitor the movement variation of the external objects until the movement variation of the external objects becomes less than the reference variation. For example, the processor 120 may determine that a movement variation of the first person object 1002, the second person object 1003, or the third person object 1004 among the recognized objects 1002 to 1007 exceeds the reference variation, and may monitor the movement variation of the external objects until the movement variation of the external objects becomes less than the reference variation without having to select an object of interest to avoid a delay of an image processing time of the objects 1002 to 1004, each of which exceed the reference variation. The electronic device 601 may periodically monitor the movement variation of the objects 1002 to 1007, and may perform a procedure of selecting an object of interest if the movement variation of the external objects becomes less than the reference variation.
Otherwise, if the movement variation of the external objects does not exceed the reference variation, proceeding to operation 909, the electronic device 601 may select the object of interest. For example, the processor 120 may select an external object (e.g., the second person object 1003) of which a movement level is less than or equal to a threshold among a plurality of images stored through the electronic device 601 as the object of interest. After operation 909, returning to the previous procedure in
Referring to
In operation 1103, the electronic device 601 determines whether a variation of the transmitted partial region exceeds a reference variation. For example, the processor 120 may determine that an operation of drawing a virtual image is additionally required due to a change in a direction in which the face of the person corresponding to the object of interest is viewed. In addition, the processor 120 may determine that the virtual image drawing operation is additionally required since a different object is added in the transmitted partial region. In addition, the processor 120 may determine that the virtual image drawing operation is not required due to a disappearance of an object included in the transmitted partial region. For example, the processor 120 may determine whether the direction of the object of interest is changed by more than a reference angle.
If the variation of the transmitted partial region does not exceed a reference variation, returning to the previous procedure, the electronic device 601 performs operations 407 to 409 of
Alternatively, if the variation of the transmitted partial region exceeds the reference variation, proceeding to operation 1105, the electronic device 601 transmits additional information including a changed partial region to the external electronic device 602. For example, in a situation where information of a partial region in which a gaze of a person corresponding to an object of interest faces to the right is transmitted in advance, the processor 120 may detect that the gaze of the person corresponding to the object of interest faces to the left, and may determine that a variation of the gaze of the person which is the object of interest exceeds the reference variation. Therefore, the processor 120 may determine that there is a change in part of the object of interest of which image quality is to be improved, and may transmit additional information including change information of a partial region corresponding to the object of interest to the external electronic device 602. The external electronic device 602 may generate image processing information for improving image quality of a corresponding partial region based on the additional information. Thereafter, returning to the previous procedure, the electronic device 601 may repeatedly perform operations 407 to 409 of

In operation 1203, the electronic device 601 determines a transmission data amount corresponding to the user level. For example, if the user is a paying user, the processor 120 may increase the transmission data amount. Alternatively, if the user is a free user, the processor 120 may decrease the transmission data amount.
In operation 1205, the electronic device 601 transmits data corresponding to a partial region to the external electronic device 601 based on the determined transmission data amount. For example, if the user is the paying user, the processor 120 may transmit data corresponding to a partial region to the external electronic device 601 via the communication module 190 of

In operation 1311, the external electronic device 602 generates additional image processing information. For example, the external electronic device 602 may generate the additional image processing information for a different partial region corresponding to a low priority, and thereafter generate additional image processing information on a partial region corresponding to a very next priority. For example, the external electronic device 602 may sequentially generate additional image processing information corresponding to a plurality of partial regions based on the priority. Additionally, if it is determined that additional image quality improvement of the raw image is unnecessary, the external electronic device 602 may not generate the additional image processing information.

That is, the external electronic device 1402 may sequentially generate a plurality of pieces of additional image processing information for correcting a plurality of partial regions based on the priority.
The external electronic device 1402 combines the improved image and the additional virtual image in operation 1421, and transmits an additional improved image to the electronic device 1401 in operation 1423. After transmitting an additional improved image of which a partial region corresponding to a low priority is corrected, the external electronic device 1402 may transmit an additional improved image of which a partial region corresponding to a very next priority is corrected. That is, the external electronic device 1402 may sequentially transmit a plurality of additional improved images to the electronic device 1401 based on the priority.
In operation 1425, the electronic device 1401 displays the additional improved image. For example, after displaying an additional improved image of which a partial region corresponding to a low priority is corrected, the electronic device 1401 may display an additional improved image of which a partial region corresponding to a very next priority is corrected. An additional improved image to be displayed next may be an image acquired through accumulated corrections of additional improved images previously displayed. Therefore, among the additional improved images sequentially displayed, a last displayed additional improved image may be an image having the best (i.e., the most improved) image quality among the additional improved images.
In operation 1427, the electronic device 1401 stores a final image of which image quality improvement is complete, and in operation 1429 the external electronic device 1402 also stores the final image of which image quality improvement is complete.

It should be appreciated that various embodiments of the present disclosure and the terms used therein are not intended to limit the technological features set forth herein to particular embodiments and include various changes, equivalents, or replacements for a corresponding embodiment. With regard to the description of the drawings, similar reference numerals may be used to refer to similar or related elements. It is to be understood that a singular form of a noun corresponding to an item may include one or more of the things, unless the relevant context clearly indicates otherwise. As used herein, each of such phrases as “A or B,” “at least one of A and B,” “at least one of A or B,” “A, B, or C,” “at least one of A, B, and C,” and “at least one of A, B, or C,” may include all possible combinations of the items enumerated together in a corresponding one of the phrases. As used herein, such terms as “1st” and “2nd,” or “first” and “second” may be used to simply distinguish a corresponding component from another, and does not limit the components in other aspect (e.g., importance or order). It is to be understood that if an element (e.g., a first element) is referred to, with or without the term “operatively” or “communicatively”, as “coupled with,” “coupled to,” “connected with,” or “connected to” another element (e.g., a second element), it means that the element may be coupled with the other element directly (e.g., wiredly), wirelessly, or via a third element.
As used herein, the term “module” may include a unit implemented in hardware, software, or firmware, and may interchangeably be used with other terms, for example, “logic,” “logic block,” “part,” or “circuitry”. A module may be a single integral component, or a minimum unit or part thereof, adapted to perform one or more functions. For example, according to an embodiment, the module may be implemented in a form of an application-specific integrated circuit (ASIC).
Various embodiments as set forth herein may be implemented as software (e.g., the program 140) including one or more instructions that are stored in a storage medium (e.g., internal memory 136 or external memory 138) that is readable by a machine (e.g., the electronic device 101). For example, a processor (e.g., the processor 120) of the machine (e.g., the electronic device 101) may invoke at least one of the one or more instructions stored in the storage medium, and execute it, with or without using one or more other components under the control of the processor. This allows the machine to be operated to perform at least one function according to the at least one instruction invoked. The one or more instructions may include a code generated by a complier or a code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. The term “non-transitory” simply means that the storage medium is a tangible device, and does not include a signal (e.g., an electromagnetic wave), but this term does not differentiate between where data is semi-permanently stored in the storage medium and where the data is temporarily stored in the storage medium.
A method according to various embodiments of the disclosure may be included and provided in a computer program product. The computer program product may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read only memory (CD-ROM)), or be distributed (e.g., downloaded or uploaded) online via an application store (e.g., Play Store™), or between two user devices (e.g., smart phones) directly. If distributed online, at least part of the computer program product may be temporarily generated or at least temporarily stored in the machine-readable storage medium, such as memory of the manufacturer's server, a server of the application store, or a relay server.
According to various embodiments, each component (e.g., a module or a program) of the above-described components may include a single entity or multiple entities. According to various embodiments, one or more of the above-described components may be omitted, or one or more other components may be added. Alternatively or additionally, a plurality of components (e.g., modules or programs) may be integrated into a single component. In such a case, according to various embodiments, the integrated component may still perform one or more functions of each of the plurality of components in the same or similar manner as they are performed by a corresponding one of the plurality of components before the integration. According to various embodiments, operations performed by the module, the program, or another component may be carried out sequentially, in parallel, repeatedly, or heuristically, or one or more of the operations may be executed in a different order or omitted, or one or more other operations may be added
While the present disclosure has been particularly shown and described with reference to certain embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure as defined by the appended claims and their equivalents
