     BACKGROUND 
     1. Field 
     The disclosure relates generally to video recording, and more particularly, but not exclusively to, a method and a system for recording a Super Slow Motion (SSM) video in a portable electronic device. 
     2. Description of Related Art 
     Super Slow motion is an effect in film-making whereby time and movement appears to be slowed down substantially in a video recording. Generally, commercially available image sensors are used in cameras output frames at 30 fps, 60 fps, 120 fps and 240 fps. Such image sensors are used in mid-tier models of portable electronic devices such as smartphones. However, to obtain image frames at a higher frame rate such as 480 fps, 960 fps and the like, related art smartphones are configured with specialized image sensors such as Fast Readout Sensors (FRS), that are highly expensive. Due to the cost factor, in the related art, configuring the specialized image sensors is a feasible option only in high end models of smartphones that are expensive. However, configuring FRS is not considered in mid-tier and low-tier models of smartphones as providing and configuring FRS increases the cost. Due to the aforementioned issue related to cost of the specialized image sensors, a Super Slow Motion (SSM) recording feature is available only in high end models of smartphones. Clearly, there is a need to provide an economical method and system which enables SSM recording in mid-tier and low-tier models of smartphones. 
     Related art techniques provide a deep-learning neural network based method that effectively creates a smooth high-quality slow motion videos of videos recorded at a regular frame rate. However, such deep-learning neural network based techniques involve high processing complexity which makes it impossible to configure and execute such techniques in mid-tier and low-tier smartphones. Such techniques cannot record a slow motion video in real-time, but rather merely convert the pre-recorded video into a slow motion video. Yet another related art technique provides a method that processes a video frame stream at a normal speed to the display device and achieves a slow movement of the selected segment. In this technique, each original frame of the selected segment is replicated to generate an extended stream adjacent each original frame. The extended stream, when provided to the display device at a normal speed, creates a slow motion effect. This technique converts a video of normal speed into a slow motion video by replicating the original frames. Replication of the original frames repeat the action captured in each adjacent frame, which results in a poor quality slow motion video.

     DETAILED DESCRIPTION 
     In the present document, the word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any embodiment or implementation of the present subject matter described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments. 
     While the disclosure is susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of examples in the drawings and will be described in detail below. It should be understood, however that it is not intended to limit the disclosure to the forms disclosed, but on the contrary, the disclosure is to cover all modifications, equivalents, and alternative falling within the scope of the disclosure. 
     The terms “comprises”, “comprising”, “includes” or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a setup, device or method that includes a list of components or steps does not include only those components or steps but may include other components or steps not expressly listed or inherent to such setup or device or method. In other words, one or more elements in a system or apparatus proceeded by “comprises... a” does not, without more constraints, preclude the existence of other elements or additional elements in the system or method. 
     Disclosed herein are a method and a system for recording a Super Slow Motion (SSM) video in a portable electronic device. As an example, the portable electronic device may include, but is not limited to, a smartphone, a tablet, a laptop and the like. A SSM video recording system may be configured to overcome one or more drawbacks mentioned in the background section. In some embodiments, the SSM video recording system records the SSM video based on motion detection, i.e. the SSM video recording system begins SSM recording when motion is detected in at least one image frame. In some embodiments, until motion is detected in at least one image frame, the SSM video recording system subjects the image frames to a frame skipping mechanism. In some embodiments, the frame skipping mechanism may include discarding multiple redundant image frames until the frame rate of the image frames is converted to a desired frame rate. Upon detecting the motion in at least one image frame, the SSM video recording system selects the image frames that capture motion, for performing an interpolation mechanism. In some embodiments, the image frames are selected for the interpolation mechanism in such a way that an effect of motion detection delay that occurred while detecting motion in the image frames is mitigated. In some embodiments, the interpolation mechanism comprises predicting an intermediate image frame between every two consecutive image frames subjected to the interpolation mechanism. Upon performing the interpolation mechanism, the SSM video recording system provides the interpolated image frames and a selected set of image frames subjected to the frame skipping mechanism, in an order, to an encoder associated with the portable electronic device, at a predefined frame rate. The encoder may encode the image frames thus received to be played at a predefined frame rate on the display, thereby achieving the SSM video recording in real-time. In some embodiments, the SSM video recording system may record the SSM video based on scene analysis apart from motion detection, i.e. the SSM recording system may begin SSM recording when a change in human expressions is detected in at least one image frame. The present disclosure is explained in detail in view of motion detection. However, the present disclosure should not be construed as limited only to motion detection, since the same process explained in the further sections, using figures, for motion detection, is applicable for scene analysis as well. 
     The present disclosure provides a method and a system for recording the SSM video in real-time without the use of specialized image sensors. The specialized image sensors are generally sensors used for capturing image frames at a high frame rate such as 480 fps, 960 fps and the like. Such specialized image sensors are highly expensive when compared to normal commercially available image sensors used for capturing image frames at a normal frame rate such as 30 fps, 60 fps, 120 fps and the like. As discussed in the background section, the specialized image sensors are generally used in high end models of smartphones to record SSM videos, due to their high cost. By contrast, since the exemplary embodiments disclosed herein provide a method to record the SSM video in real-time without the use of specialized sensors, the exemplary embodiments disclosed herein eliminate the cost associated with the specialized image sensors. Therefore, the exemplary embodiments disclosed herein enable the real-time SSM video recording not only in high end models but also in mid-tier models and low-tier models of smartphones. Further, the method is a “light weight” method unlike neural network based methods, and hence, may be easily configured and executed in any model of smartphone without affecting the working of the smartphone. Furthermore, the method generates images frames of a high frame rate based on the interpolation mechanism, which predicts the motion between two image frames. Therefore, the exemplary embodiments disclosed herein achieve improved SSM video recording, unlike the related art techniques which use a replication mechanism for achieving image frames of high frame rate. 
     In the description that follows, a description of an embodiment with several components in communication with each other does not imply that all such components are required. On the contrary a variety of optional components are described to illustrate the wide variety of possible embodiments. 
     In the following detailed description of the embodiments of the disclosure, reference is made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration specific embodiments in which the disclosure may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the disclosure, and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the scope of the present disclosure. The following description is, therefore, not to be taken in a limiting sense. 
       FIG.  1    shows an exemplary architecture for recording a Super Slow Motion (SSM) video in a portable electronic device, according to an embodiment. 
     The architecture  100  includes a portable electronic device  101 , an image capturing device  103 , a SSM video recording system  105 , and an encoder  107 . In some embodiments, the portable electronic device  101  may be a smartphone, a laptop, a tablet and the like. In some embodiments, an image capturing device  103  may be configured to communicate with the portable electronic device  101  for capturing images. As an example, the image capturing device  103  may be a camera comprising a commercially available normal image sensor. In some embodiments, the image capturing device  103  may be provided within the portable electronic device  101 . In some embodiments, the normal image sensor may be an image sensor capable of capturing image frames at a normal frame rate such as 30 fps, 60 fps, 120 fps, 240 fps and the like. Further, the SSM video recording system  105  may be associated with the portable electronic device  101  via a communication network, and thus may communicate with the portable electronic device  101  through the communication network. The communication network may be at least one of a wired communication network and a wireless communication network. In some embodiments, the SSM video recording system  105  may be configured within the portable electronic device  101 . 
     The SSM video recording system  105  may include a processor  109 , an Input/Output (I/O) interface  111  and a memory  113 . The processor  109  may be a microprocessor, and in some embodiments, may include a plurality of microprocessors. 
     The I/O interface  111  receives original image frames from the image capturing device  103 , in real-time. In some embodiments, the original image frames may be the image frames captured at a first frame rate. In some embodiments, the first frame rate may be preconfigured in the SSM video recording system  105 . As an example, the first frame rate may be 240 fps. 
     The processor  109  may store the original image frames of the first frame rate in a queue, while simultaneously the processor  109  may transmit corresponding image frames of a second frame rate, for display. In some embodiments, the processor  109  may transmit the corresponding image frames of the second frame rate to the portable electronic device  101  for display thereon. In some embodiments, the processor  109  may generate image frames of the second frame rate from the original image frames, for display. In some embodiments, the second frame rate may be preconfigured in the SSM video recording system  105 . In some embodiments, the image frames of the second frame rate may be displayed on a display screen of the portable electronic device  101 . As an example, the second frame rate may be 60 fps. Prior to display, the processor  109  may detect a presence of motion from each of the image frames of the second frame rate using a predefined motion detection library. In some other embodiments, the processor  109  may detect the presence of motion in each of the original image frames of the first frame rate. In some embodiments, a Motion Detection (MD) delay may occur while detecting the presence of motion using the predefined motion detection library, due to one or more conditions of a system associated with the predefined motion detection library. As an example, the one or more conditions of the system may include, but not limited to, memory utilization, Central Processing Unit (CPU) utilization and the like. In some embodiments, the frame rate of each of the original image frames stored in the queue may be reduced to the fourth frame rate based on a frame skipping mechanism, until the presence of motion is detected in at least one of the image frames of the second frame rate. 
     Upon detecting the presence of motion in at least one of the image frames of the second frame rate, the processor  109  may generate a trigger at a current time instance. Further, the processor  109  may store in a buffer of predefined buffer depth, a first set of image frames. In some embodiments, the first set of image frames are the original image frames captured at a time instance preceding the current time instance at which the trigger was generated. Further, the processor  109  may also store in the buffer of the predefined buffer depth, a second set of image frames selected for performing an interpolation mechanism, upon generating the trigger. In some embodiments, the second set of image frames are the original image frames, comprising motion, that were captured prior to the current time instance at which the presence of motion was detected, to mitigate the MD delay. In some embodiments, the processor  109  may be unable to subject the second set of image frames to motion detection due to occurrence of the MD delay. Along with the second set of image frames, the processor  109  may also provide a third set of image frames for the interpolation mechanism. In some embodiments, the third set of image frames are a predefined number of the original image frames comprising motion, that are selected by the processor  109  for performing the interpolation mechanism upon generating the trigger. Further, the processor  109  may generate image frames of a third frame rate by converting a frame rate of the second set of image frames and the third set of image frames from the first frame rate to the third frame rate, based on the interpolation mechanism. In some embodiments, the third frame rate may be predefined in the SSM video recording system  105 . As an example, the third frame rate may be 480 fps, 960 fps and the like. Upon generating the image frames of the third frame rate, the processor  109  may generate image frames of a fourth frame rate by converting the frame rate of the first set of image frames from the first frame rate to the fourth frame rate based on a frame skipping mechanism. In some embodiments, the third frame rate may be predefined in the SSM video recording system  105 . As an example, the fourth frame rate may be 30 fps. In some embodiments, the second frame rate and the fourth frame rate are lower than the first frame rate. Whereas the third frame rate is higher than the first frame rate. 
     Finally, the processor  109  may transmit the image frames of the fourth frame rate, the image frames of the third frame rate, and a fourth set of image frames captured at a time instance succeeding the current time instance, in an order, to the encoder  107  associated with the SSM video recording system  105  for encoding. The encoded image frames are recorded as the SSM video, or played back as the SSM video. In some embodiments, the frame rate of the fourth set of image frames may be converted to the fourth frame rate based on the frame skipping mechanism before transmitting to the encoder  107 . In some embodiments, the encoder  107  may encode the image frames of the third frame rate to be played at the fourth frame rate on the display screen. 
       FIG.  2    shows a detailed block diagram of a Super Slow Motion (SSM) video recording system of the exemplary architecture  100  of  FIG.  1   , according to an embodiment. 
     In some implementations, the SSM video recording system  105  may include data  203  and modules  205 . As an example, the data  203  is stored in the memory  113  configured in the SSM video recording system  105  as shown in the  FIG.  2   . In one embodiment, the data  203  may include input image data  207 , interpolated frame data  209 , skipped frame data  211  and other data  213 . The modules  205  are described below in detail. 
     In some embodiments, the data  203  may be stored in the memory  113  in form of various data structures. Additionally, the data  203  may be organized using data models, such as relational or hierarchical data models. The other data  213  may store data, including temporary data and temporary files, generated by the modules  205  for performing the various functions of the SSM video recording system  105 . 
     In some embodiments, the data  203  stored in the memory  113  may be processed by the modules  205  of the SSM video recording system  105 . The modules  205  may be stored within the memory  113 . In an example embodiment, the modules  205  communicatively coupled to the processor  109  configured in the SSM video recording system  105 , may be provided outside the memory  113  as shown in  FIG.  2    and implemented as hardware. As used herein, the term “modules” refer to an application specific integrated circuit (ASIC), an electronic circuit, a processor (shared, dedicated, or group) and memory that execute one or more software or firmware programs, a combinational logic circuit, and/or other suitable components that provide the described functionality. 
     In some embodiments, the modules  205  may include, for example, a receiving module  221 , a preview module  223 , a motion detection module  225 , a frame skipping module  227 , a frame selecting module  229 , an interpolation module  231 , a transmitting module  233  and other modules  234 . The other modules  234  may be used to perform various miscellaneous functionalities of the SSM video recording system  105 . It will be appreciated that, in some embodiments, such aforementioned modules  205  may be represented as a single module, or in other embodiments as a combination of different modules. 
     In some embodiments, the receiving module  221  may initially receive original image frames in real-time from an image capturing device  103  configured to a portable electronic device  101 . In some embodiments, the original image frames may be the image frames captured at a first frame rate. The first frame rate may be preconfigured in the SSM video recording system  105 . As an example, the first frame rate may be 240 fps. As an example, the image capturing device  103  may be a camera comprising a commercially available normal image sensor. In some embodiments, the normal image sensor may be an image sensor capable of capturing image frames at a normal frame rate such as 30 fps, 60 fps, 120 fps, 240 fps and the like. The original image frames may be subjected to pre-processing that may include noise reduction, auto exposure, auto focus, auto white balance in high speed and high quality and the like. The original image frames thus received may be stored as input image data  207 . 
     Further, in some embodiments, the preview module  223  may transmit the image frames of a second frame rate to the portable electronic device  101  for display. In some embodiments, the image frames of the second frame rate may be generated from the original image frames. In some embodiments, the second frame rate may be preconfigured in the SSM video recording system  105 . As an example, the second frame rate may be 60 fps.. In some embodiments, the image frames of the second frame rate may be displayed on a display screen of the portable electronic device  101 . In some embodiments, the motion detection module  225  may detect presence of motion in the image frames of the second frame rate, prior to transmission for display of the image frames of the second frame rate on the display screen. 
     In some embodiments, the motion detection module  225  may detect the presence of motion from the image frames of the second frame rate using a predefined motion detection library. In some embodiments, the motion detection module  225  may compare each image frame of the second frame rate with a subsequent image frame of the second frame rate and correlate a result of the comparison thus determined with data stored in the predefined motion detection library to detect presence of motion. In some embodiments, the motion detection module  225  may compare each image frame of the second frame rate with a next image frame of the second frame rate immediately following the each image frame. However, a Motion Detection (MD) delay may occur while detecting the presence of motion using the predefined motion detection library, due to one or more conditions of a system associated with the predefined motion detection library. As an example, the one or more conditions of the system may include, but not limited to, memory utilization, Central Processing Unit (CPU) utilization, processing delay, memory availability and the like. Due to such MD delay, the motion detection module  225  may actually miss detecting the presence of motion in a few image frames of the second frame rate, though motion is present in those image frames of the second frame rate. Therefore, generally when the motion detection module  225  detects the presence of motion in at least one image frame of the second frame rate, a few image frames of the second frame rate that were captured prior to the current time instance at which the motion was detected, are also considered to be the image frames comprising motion. This is to mitigate the MD delay in detecting the presence of motion in the image frames. In some embodiments, until the motion detection module  225  detects the presence of motion in at least one of the image frames of the second frame rate, the frame rate of each of the original image frames is reduced to a fourth frame rate based on a frame skipping mechanism. In some embodiments, the fourth frame rate may be preconfigured in the SSM video recording system  105 . As an example, the fourth frame rate may be 30 fps. 
     In some embodiments, the frame skipping mechanism may be performed by a frame skipping module  227 . The frame skipping mechanism may include discarding multiple redundant image frames from the original image frames until the frame rate of the original image frames is converted to a desired frame rate. As an example, consider that the original image frames are at the frame rate 240 fps and the desired frame rate is 30 fps. Therefore, by using the frame skipping mechanism, the multiple redundant frames, which do not contain any motion, may be discarded until the frame rate of the original image frames reduces to 30 fps from 240 fps. The process of frame skipping mechanism is explained below with reference to  FIG.  3 A  and  FIG.  3 B . 
       FIG.  3 A  and  FIG.  3 B  show an exemplary illustration of a frame skipping mechanism, according to embodiments. As shown in the  FIG.  3 A , consider an example in which the original image frames are stored in a queue  226  before applying the frame skipping mechanism. In some embodiments, the queue  226  may be included in the memory  113 . In some embodiments, the input rate of the original image frames is less than the output rate of the original image frames. Therefore, the queue is introduced to manage transmission of the original image frames to the frame skipping module  227  prior to subjecting the original image frames to the frame skipping mechanism. Consider an example in which the original image frames are at the frame rate 240 fps and the desired frame rate is 30 fps. Therefore, to achieve the frame rate of 30 fps, the number of image frames have to be reduced from 240 to 30 per second, which means one image frame out of every eight image frames are selected. Accordingly, the frame skipping module  227  may consider the original image frames in an order as received from the queue. As shown in the  FIG.  3 A , the frame skipping module  227  may mark one original image frame from a set of 8 original image frames as “OK” and may mark rest of the 7 image frames in the set of 8 original image frames as “ERROR” or “IGNORE”, etc. Therefore, the frame skipping module  227  may retain the original image frame marked as “OK” and discard the rest of the original image frames marked as “ERROR”. The frame skipping module  227  may further repeat the same process for subsequent sets of 8 original image frames, until the number of image frames are reduced from 240 to 30 image frames per second. Similarly, as an example, consider the original image frames are at the frame rate 240 fps and the desired frame rate is 60 fps. Therefore, to achieve the frame rate of 60 fps, the number of image frames are reduced from 240 to 60 per second, which means one image frame out of every four image frames are selected. Accordingly, the frame skipping module  227  may mark one image frame from a set of 4 original image frames as “OK” and rest of the 3 original images frames as “ERROR” or “IGNORE”, etc., as shown in the  FIG.  3 B . In some embodiments, the one original image frame marked as “OK” may be a first image frame in the set of the 8 original image frames or the set of 4 original image frames as selected by the frame skipping module  227 . In some other embodiments, the one original image frame marked as “OK” may be any image frame in the set of the 8 original image frames or the set of 4 original image frames as selected by the frame skipping module  227 . In yet other embodiments, the frame skipping module  227  may select the one original image frame marked as “OK” based on one or more predefined selection factors, from the set of the 8 original image frames or the set of 4 original image frames. 
     In some embodiments, upon detecting the motion in at least one of the image frames of the second frame rate, in a current time instance, the motion detection module  225  may generate a trigger to indicate the presence of motion. Further, the processor  109  may initialize a buffer of a predefined buffer depth. In some embodiments, the buffer may be a circular buffer. In some embodiments, the predefined buffer depth may be determined using the below Equation 1.

             required 
           
         
       
     
     In the above Equation 1, “Buffer depth” denotes the size of the buffer; “Initial low fps frames required” (also referred as a first set of image frames in later sections of the present disclosure) denotes the number of original image frames of a time instance, that do not include any detectable motion, that are selected for the frame skipping mechanism; and “Number of MD delay frames” (also referred as a second set of image frames in later sections of the present disclosure) denotes the number of original image frames passed in real-time during motion detection. In this scenario, the original image frames passed in real-time are the original image frames that could not be subjected to motion detection due to the occurrence of the MD delay. 
     In some embodiments, the number of MD delay frames, i.e. the second set of image frames, may be detected using the below Equation 2.

     In the above Equation 2, “Estimated MD delay” denotes MD delay which is expected at the time of motion detection; and “Sensor fps” denotes the frame rate of the image sensor used in the image capturing device  103  to capture the original image frames. In some embodiments, the estimated MD delay may vary for different models of the portable electronic devices  101  as the system parameters and conditions such as processing capacity, speed, memory availability and the like vary for each model of the portable electronic device  101 . 
     As an example, consider that the sensor fps is 240 fps and the estimated MD delay is 28 ms. By substituting these values in the above Equation 2, the processor  109  determines the number of MD delay frames to be 7. 
     Further, consider that the initial low fps frames required, i.e. the first set of image frames, are image frames of 30 fps for 0.3 seconds. Therefore, the total number of the 240 fps original image frames for 0.3 seconds should be converted to 30 fps image frames for 0.3 seconds. The number of original image frames of 240 fps for 0.3 seconds would be (240*0.3), which is 72 original image frames. The processor  109  provides these 72 original image frames, at a later stage (explained below in the subsequent paragraphs), to the frame skipping mechanism to convert the frame rate of the 72 original image frames from 240 fps to 30 fps. 
     Further, the processor  109  determines the buffer depth by substituting the initial low fps frames required, and the number of MD delay frames determined using Equation 2, in the above Equation 1. Therefore, in this example, the buffer depth is 79, which is a sum of 72 image frames and the 7 MD delay frames. 
     Since the MD delay, frame rate of the image sensor, and the number of initial low fps frames required are defined according to the requirement, the buffer depth is accordingly predefined in the SSM video recording system  105 . 
     Referring back to the motion detection module  225 , when the motion detection module  225  generates the trigger, the frame selecting module  229  may select and store the first set of image frames and the second set of image frames in the buffer. In some embodiments, the first set of image frames are the original image frames captured at a time instance preceding the current time instance at which the trigger was generated. The frame selecting module  229  selects the first set of image frames for performing the frame skipping mechanism. In some embodiments, the second set of image frames are the original image frames of the current time instance, comprising motion, that were captured prior to the time when the presence of motion was detected. The second set of image frames are used for mitigating/compensating the MD delay in detecting the presence of motion in the image frames. The frame selecting module  229  selects the second set of image frames for performing an interpolation mechanism. The frame selecting module  229  further selects a third set of image frames for performing the interpolation mechanism. In some embodiments, the third set of image frames are a predefined number of the original image frames, comprising motion, selected for performing the interpolation mechanism upon generating the trigger. The third set of image frames are the image frames of the current time instance that are captured after the image frame of the second frame rate in which the presence of motion was detected by the motion detection module  225 . The frame selecting module  229  may provide the second set of image frames and the third set of image frames to the interpolation module  231  for performing the interpolation mechanism. In some embodiments, the input rate of the second set of image frames and the third set of image frames is faster than the output rate of the image frames generated by the interpolation module  231 . Therefore, to manage the transmission of the second set of image frames and the third set of image frames to the interpolation module  231 , a queue is introduced to store the second set of image frames and the third set of image frames. 
     In some embodiments, the interpolation mechanism may include, but is not limited to, predicting an intermediate image frame between every two consecutive image frames of the second set of image frames and/or between every two consecutive image frames of the third set of image frames, using one or more predefined frame predicting techniques. An exemplary illustration of the interpolation mechanism is as shown in the  FIG.  4   . 
       FIG.  4    shows an exemplary illustration of an interpolation mechanism, according to an embodiment. In  FIG.  4   , image frame “n” and image frame “n+1” are two exemplary consequent image frames of either the second set of image frames or the third set of image frames. When the image frame “n” and image frame “n+1” are provided to the interpolation module  231 , the interpolation module  231  may interpolate a new image frame between the image frame “n” and image frame “n+1”. In some embodiments, the interpolation module  231  may generate the new image frame for interpolation by predicting the image frame between the image frame “n” and image frame “n+1”, i.e. by predicting motion of a principle object between the image frame “n” and image frame “n+1”, as shown in  FIG.  4   . In the example shown in  FIG.  4   , the principle object is a ball, whose position change has been predicted and indicated in the new image frame, relative to the position of the ball in the image frame “n” and image frame “n+1”. 
     In some embodiments, using the interpolation mechanism explained above, the interpolation module  231  may generate image frames of a third frame rate by interpolating a new image frame between every two consecutive image frames of the second set of image frames and/or between every two consecutive image frames of the third set of image frames. In some embodiments, the third frame rate may be preconfigured in the SSM video recording system  105 . As an example, the third frame rate may be 480 fps, 960 fps and the like. The image frames subjected to the interpolation mechanism and the image frames generated using the interpolation mechanism may be stored as the interpolated frame data  209 . 
     In parallel with the operation above, the frame skipping module  227  may generate image frames of a fourth frame rate by converting the frame rate of the first set of image frames from the first frame rate to the fourth frame rate based on the frame skipping mechanism explained above. In some embodiments, the fourth frame rate may be preconfigured in the SSM video recording system  105 . As an example, the fourth frame rate may be 30 fps. As an example, consider that the first frame rate is 240 fps and the fourth frame rate is 30 fps. In such scenarios, the frame skipping module  227  may consider sets of 8 image frames each, continuously, and select one image frame from each set, while discarding rest of the 7 image frames from each set, until the image frames of 240 fps are converted to image frames of 30 fps, as described above with respect to  FIGS.  3 A and  3 B . In some embodiments, the second frame rate and the fourth frame rate may be lower than the first frame rate. Whereas the third frame rate is higher than the first frame rate. 
     Further, the frame selecting module  229  may select a fourth set of images for performing the frame skipping mechanism. In some embodiments, the fourth set of image frames may be the image frames that are captured at a time instance succeeding the current time instance. In other words, the fourth set of image frames are the image frames captured after the third set of image frames selected for the interpolation mechanism. In some embodiments, the fourth set of images may or may not comprise the presence of motion. The frame selecting module  229  may provide the fourth set of images to the frame skipping module  227  for performing the frame skipping mechanism. In some embodiments, the frame skipping module  227  may convert the frame rate of the fourth set of image frames from the first frame rate to the fourth frame rate using the frame skipping mechanism. In some embodiments, the fourth set of image frames upon being subjected to the frame skipping mechanism may be referred as terminating image frames. The image frames subjected to the frame skipping mechanism and the image frames generated as a result of the frame skipping mechanism may be stored as the skipped frame data  211 . 
     Further, in some embodiments, the transmitting module  233  may transmit the image frames of the fourth frame rate, the image frames of the third frame rate, and the terminating image frames, in an order, to an encoder  107 , for encoding. Further, in some embodiments, at least one queue may be introduced for managing transmission of the image frames of the fourth frame rate, the image frames of the third frame rate, and the terminating image frames to the encoder  107 . That is, in some embodiments, the image frames to be transmitted may be stored in at least one queue prior to transmission to the encoder  107 . In some embodiments, the encoder  107  may be associated with the SSM video recording system  105 . In some embodiments, the encoder  107  may be in communication with the SSM video recording system  105 . The encoder  107  may convert and store the image frames thus received, into a digital format which may be displayed/viewed on a display screen of the portable electronic device  101 . In some embodiments, the encoder  107  may encode and store the image frames of the third frame rate to be played at the fourth frame rate on the display screen. 
     Upon encoding, the encoder  107  may initially play the image frames of the fourth frame rate, then the image frames of the third frame rate at the fourth frame rate, and thereafter the terminating image frames, each, at the fourth frame rate, on the display screen. In some embodiments, the encoder  107  may be communicatively coupled to the portable electronic device  101  and may provide the image frames to the portable electronic device  101  for playing. In some embodiments, the encoder  107  may be provided within the portable electronic device  101  and may thus initially play the image frames on the display screen of the portable electronic device  101 . The image frames of the third frame rate that are encoded to be played at the fourth frame rate enables the SSM video recording system  105  to achieve the effect of Super Slow Motion recording. 
     Henceforth, the process of recording the SSM video in the portable electronic device  101  is explained with the help of one or more examples for better understanding of the present disclosure. However, the one or more examples should not be considered as a limitation of the present disclosure. 
       FIG.  5    shows an exemplary scenario for recording a Super Slow Motion (SSM) video in a portable electronic device, according to an embodiment. Consider an exemplary scenario as shown in the  FIG.  5   , and consider the following exemplary details for explaining the process of recording the SSM video in the portable electronic device in the exemplary scenario:
     Portable electronic device: Smartphone   Image capturing device: Camera   Image sensor: Normal commercially available sensor with Frame Rate (FR) 240 fps.   First FR: 240 fps   Second FR: 60 fps   Third FR: 480 fps   Fourth FR: 30 fps   

     In the example of  FIG.  5   , the image sensor  235 , the image signal processor  237 , the motion detection module  225 , the circular buffer  239 , the frame skipping module  227 , the display screen  241 , the interpolation module  231 , and the encoder  107  may be provided on the portable electronic device  101 . That is,  FIG.  1    shows the architecture  100  as including separate components. However, in some embodiments, the components of the architecture  100  may be included within the portable electronic device  101  itself. 
     Consider the camera configured in the smartphone captures original image frames at 240 fps. As shown in the  FIG.  5   , the Image Signal Processor (ISP)  237  component of the camera is configured to process one or more signals received from the image sensor  235  configured in the camera, while capturing the original image frames. The ISP  237  processes the one or more signals into two streams of image frames. In some embodiments, one stream comprises the original image frames of frame rate 240 fps which are transmitted for performing post processing activities via queue 2, and another stream comprises image frames of frame rate 60 fps, which are transmitted for preview display on a display screen of the smartphone via queue 1, as shown in the  FIG.  5   . However, before the image frames of 60 fps are displayed on the display screen, the image frames are routed to the motion detection module  225  for detecting the presence of motion in the image frames, i.e. the motion detection module  225  checks whether principle objects in the image frames of 60 fps contain any kind of motion or not. Until the presence of motion is detected, the original image frames of 240 fps are reduced to image frames of 30 fps using the frame skipping mechanism. The processor  109  may manage transmission of the original image frames of 240 fps to the frame skipping module  227  through a queue 2 as shown in the  FIG.  5   , for performing the frame skipping mechanism. 
     Consider that the presence of motion is detected in an image frame of 60 fps, with a MD delay of 28 ms. Further, consider that the image frame of 60 fps in which the motion is detected, corresponds to an image frame “X” of 240 fps provided by the ISP  237 . Due to the MD delay, a few image frames captured after the image frame “X” could not be subjected to motion detection. Therefore, the frame selecting module  229  selects 7 image frames of 240 fps as the second set of image frames (also referred as MD delay frames) to compensate the MD delay of 28 ms, using the equation 2 described above. The 7 MD delay image frames of 240 fps are the frames that were captured immediately prior to the current time instance at which the motion is detected in the image frame of 60 fps. In other words, the current time instance is the time instance at which the trigger is generated. Further, consider the frame selecting module  229  selects the first set of images of 240 fps captured before the 7 MD delay image frames, for an interval of 0.3 seconds. Therefore, totally the frame selecting module  229  may select (240 fps * 0.3), i.e. 72 image frames of 240 fps, as the first set of image frames. The first set of image frames do not contain any motion, but are used for ensuring a continuity to the SSM video. The frame selecting module  229  now stores the first set of image frames and the second set of image frames in the circular buffer  239  as shown in the  FIG.  5   . Further, consider the frame selecting module  229  selects the third set of image frames of 240 fps, that are captured after the image frame “X”, such that the 7 MD delay image frames, the image frame “X” and the third set of images together form an interval of 0.4 seconds. For the interval of 0.4 seconds, totally the frame selecting module  229  should select (240 fps * 0.4), i.e. 96 image frames. However, since the 7 MD delay frames and the image frame “X” are already selected, therefore, the frame selecting module  229  now selects remaining 88 image frames of 240 fps as the third set of image frames. The third set of image frames contain motion, which is a continuation of the motion detected in the image frame “X”. Further, consider the frame selecting module  229  selects a fourth set of image frames of 240 fps, that are captured after the 88 third set of image frames, for an interval of 0.3 seconds. Therefore, totally the frame selecting module  229  may select (240 fps * 0.3), i.e. 72 image frames of 240 fps, as the fourth set of image frames. The fourth set of image frames may or may not contain motion, but are used to ensure continuity to the SSM video. 
     Therefore, upon receiving the trigger indicating the presence of motion from the motion detection module  225 , the processor  109  transmits the 72 first set of image frames of 240 fps to the frame skipping module  227 . In parallel, the processor  109  transmits the 7 second set of image frames of 240 fps, the image frame “X”, and the 88 third set of image frames (totally 96 image frames) to the interpolation module  231 , through the queue 3 as shown in the  FIG.  5   . The frame skipping module  227  converts the 72 first set of image frames of 240 fps to 9 image frames of 30 fps using the frame skipping mechanism. On the other hand, the interpolation module  231  converts the 96 image frames of 240 fps into 192 frames of 480 fps by interpolating a new image frame between every two consecutive image frames. The interpolation module  231  predicts the motion of the principle object in every new image frame based on the motion of the principle object in the corresponding two consecutive image frames. 
     Upon converting, the processor  109  transmits that 9 image frames of 30 fps obtained from 72 first set of image frames of 240 fps to the encoder  107  through the queue 4 as shown in the  FIG.  5   . Thereafter, the processor  109  transmits the 192 image frames of 480 fps obtained from 96 image frames (7 MD delay frames, image frame “X”, and 88 third set of image frames) of 240 fps to the encoder  107  through the queue 5 as shown in the  FIG.  5   . Finally, the processor  109  sends the 72 fourth set of image frames of 240 fps to the frame skipping module  227  to obtain 9 image frames of 30 fps (also referred as terminating image frames) and thereafter transmits the 9 terminating image frames of 30 fps to the encoder  107  through the queue 4 as shown in the  FIG.  5   . This flow of transmitting the exemplary image frames to the encoder  107  while recording the SSM video, as explained in the paragraph above, is pictorially represented in the  FIG.  6 A . 
       FIG.  6 A  and  FIG.  6 B  show, respectively, an exemplary illustration of recording and playback of exemplary image frames, according to embodiments. As shown in the  FIG.  6 A , portion  243  of 0.3 seconds time interval comprises 9 image frames of 30 fps obtained from 72 first set of image frames of 240 fps. Further, portion  245  of 0.4 seconds time interval comprises 192 image frames of 480 fps obtained from 96 image frames of 240 fps. Finally, portion  247  of 0.3 seconds time interval comprises 9 terminating image frames of 30 fps.  FIG.  6 B  shows the playback of the encoded image frames, wherein initially image frames of the portion  243  are played at 30 fps for the time interval of 0.3 seconds, thereafter image frames of the portion  245  which are of frame rate 480 fps are played at 30 fps, due to which the original recorded and encoded image frames of 0.4 seconds time interval are displayed as super slow motion at 30 fps for 6.4 seconds time interval. Finally, the image frames of portion  247  are played at 30 fps. 
       FIG.  7    shows a flowchart illustrating a method of recording a SSM video in a portable electronic device, according to an embodiment. 
     As illustrated in  FIG.  7   , the method  300  includes one or more blocks illustrating a method of recording a Super Slow Motion (SSM) video in a portable electronic device  101 . The method  300  may be described in the general context of computer executable code. Generally, computer executable code may include instructions, routines, programs, objects, components, data structures, procedures, modules, and functions, which are loaded onto a processor and executed to perform functions or implement data types. 
     The order in which the method  300  is described is not intended to be construed as a limitation, and any number of the described method blocks may be combined in any order to implement the method  300 . Additionally, individual blocks may be deleted from the method  300  without departing from the spirit and scope of the subject matter described herein. Furthermore, the method  300  may be implemented in any suitable hardware, software, firmware, or combination thereof. 
     At block  301 , the method  300  may include receiving, by a processor  109  configured in a SSM video recording system  105  of the portable electronic device  101 , original image frames from an image capturing device  103  configured in the portable electronic device  101 . In some embodiments, the original image frames may be captured at a first frame rate. As an example, the first frame rate may be 240 fps. 
     At block  303 , the method  300  may include transmitting, by the processor  109 , image frames of a second frame rate, for display. In some embodiments, the processor  109  may generate the image frames of the second frame rate from the original image frames. As an example, the second frame rate may be 60 fps. 
     At block  305 , the method  300  may include detecting, by the processor  109 , a presence of motion from each of the image frames of the second frame rate using a predefined motion detection library. 
     At block  307 , the method  300  may include generating, by the processor  109 , a trigger when the presence of motion is detected in at least one of the image frames of the second frame rate, in a current time instance. 
     At block  309 , the method  300  may include storing, by the processor  109 , a first set of image frames and a second set of image frames in a buffer of predefined buffer depth. In some embodiments, the first set of image frames are the original image frames captured at a time instance preceding the current time instance at which the trigger is generated. In some embodiments, the second set of image frames are the original image frames of the current time instance, comprising motion, that were captured prior to the current time instance at which the presence of motion was detected, to mitigate a Motion Detection (MD) delay. The first set of image frames are selected for performing a frame skipping mechanism and the second set of image frames are selected for performing an interpolation mechanism upon generating the trigger. In some embodiments, the frame skipping mechanism may include discarding multiple redundant image frames from the original image frames until the frame rate of the original image frames is converted to a desired frame rate. In some embodiments, the interpolation mechanism may include predicting an intermediate image frame between every two consecutive second set of image frames and the third set of image frames, using one or more predefined frame predicting techniques. 
     At block  311 , the method  300  may include generating, by the processor  109 , image frames of a third frame rate by converting a frame rate of the second set of image frames and a third set of image frames from the first frame rate to the third frame rate, based on the interpolation mechanism. In some embodiments, the third set of image frames are a predefined number of the original image frames comprising motion, selected for performing the interpolation mechanism upon generating the trigger. The third set of image frames are the image frames captured after the image frame of the second frame rate in which the presence of motion was detected. 
     At block  313 , the method  300  may include generating, by the processor  109 , image frames of a fourth frame rate by converting the frame rate of the first set of image frames from the first frame rate to the fourth frame rate based on the frame skipping mechanism. 
     At block  315 , the method  300  may include transmitting, by the processor  109 , the image frames of the fourth frame rate, the image frames of the third frame rate and a fourth set of image frames captured at a time instance succeeding the current time instance, in an order, to an encoder  107  for encoding. In some embodiments, the encoder  107  is associated with the SSM video recording system  105 . The processor  109  may convert frame rate of the fourth set of image frames to the fourth frame rate, based on the frame skipping mechanism, before transmitting them to the encoder  107 .
