20180322908
This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2017-0056229, filed on May 2, 2017, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.
The present disclosure relates to an apparatus and method for applying a dynamic effect to a picture in an electronic device.
With the advance of information communication techniques and semiconductor techniques, electronic devices are being developed into multimedia devices for providing various multimedia services. For example, the multimedia service may include at least one of a voice call service, a message service, a broadcasting service, a wireless Internet service, a camera service, a picture playback service, and a music playback service.
The electronic device may provide a picture service for playing back a video file. For example, the electronic device may capture a picture through a camera, or store at least one video file received from an external device. The electronic device may play back a video file selected by a user among the at least one video file.
When a video file is played back, an electronic device may play back the video file by decoding picture and audio signals included in the video file. For example, the electronic device may decode a image frame (or a picture signal) of the video file through a video decoder, and may interpret an audio signal of the video file through an audio decoder. The electronic device may play back the video file by synchronizing the decoded picture and audio signals. In this case, the electronic device plays back the video file by simply decoding the video file. Therefore, in case of a monotonous video file having a small change between frames, it is difficult to make a user get interested, which may result in a problem in that accessibility of the video file is decreased. For example, the accessibility of the video file may include how frequently the video file is played back.
Various embodiments of the present disclosure provide an apparatus and method for providing a dynamic effect to a still picture, when the picture is played back in an electronic device.
According to various embodiments of the present disclosure, an electronic device may include a memory, a display, and a processor. The processor may be configured to identify an amount of change between one or more image frames stored in the memory, to detect at least one image frame among the one or more image frames based on the amount of change, to determine a partial region from an entire region of the at least one image frame, to determine a playback mode corresponding to the partial region, and to display the partial region based on the playback mode using the display.
According to various embodiments of the present disclosure, a method of operating an electronic device may include identifying an amount of change between one or more images stored in a memory electrically coupled to the electronic device, detecting at least one image frame among the one or more image frames based on the amount of change, determining a partial region from an entire region of the at least one image frame, determining a playback mode corresponding to the partial region, and displaying the partial region based on the playback mode.
According to various embodiments of the present disclosure, an electronic device may include a memory, a display, and a processor.

Referring to
The bus 110, for example, may include a circuit that connects the components (120 to 170) and transmits signals (for example, control messages and/or data) among the components.
The processor 120 may include various processing circuitry, such as, for example, and without limitation, one or more of a dedicated processor, a Central Processing Unit (CPU), an Application Processor (AP), a Communication Processor (CP), and/or an Image Signal Processor (ISP), or the like. The processor 120, for example, can perform calculation or data processing about control and/or communication of one or more other components of the electronic device 101.
According to an embodiment, the processor 120 may identify at least one static interval to apply a dynamic effect in a video file that can be played back. For example, the processor 120 may analyze a similarity between a series of image frames (video frames) included in the video file. For example, the processor 120 may compare property values between the image frames to analyze the similarity between the image frames. The processor 120 may set the series of image frames, of which the similarity between the image frames is greater than or equal to a reference value, as the static interval. For example, the processor 120 may extract a Region Of Interest (ROI) from a saliency map of at least one image frame included in the static interval. The processor 120 may set the ROI of the image frame as a main region for applying the dynamic effect. For example, the processor 120 may create the saliency map of the image frame using a deep learning scheme (e.g., a Convolutional Neural Network (CNN), or the like, but is not limited thereto). For example, the processor 120 may set at least part of the at least one image frame included in the video file as the main region. The processor 120 may analyze a similarity of the main region between the series of image frames. For example, the processor 120 may compare at least one of a center coordinate, size, and location of the main region between the image frames to analyze the similarly of the main region between the image frames. The processor 120 may set the series of image frames, of which the similarity between the image frames is greater than or equal to the reference value, as the static interval. For example, the processor 120 may set a main interval based on face information or focus information detected from the image frame.
According to an embodiment, the processor 120 may determine a playback mode to be applied to the static interval. For example, the processor 120 may divide the series of image frames included in the video file into a plurality of shots. For example, the static interval may include at least one shot of which a similarity between image frames is greater than or equal to a reference value among the plurality of shots. The processor 120 may determine a playback pattern of the static interval based on at least one of a main region (e.g., a size and a location) in the image frame, a length of the static interval, and a global motion. The processor 120 may determine at least one playback mode to be applied to the static interval based on at least one of a probability model and a shot transition history. For example, the probability model of the playback mode may include a transition probability between playback modes according to a pattern (e.g., an order) of applying a dynamic effect. For example, the probability model of the playback mode may be set by a user or may be set by a pattern of applying a dynamic effect used by a specific person (e.g., a movie director). For example, the processor 120 may receive the pattern of applying the dynamic effect used by the specific person from an external device (e.g., a server). For example, when there is no history of applying the dynamic effect, the probability model of the playback mode may be randomly set or may be set by the user. When the history of applying the dynamic effect is accumulated, the processor 120 may update the transition probability of the playback mode based on the history of applying the dynamic effect. For example, in order to decrease the number of times of using a playback mode which is used relatively many times, the processor 120 may decrease a probability for transitioning to the playback mode. For example, the playback mode may include at least one of zoom-in, zoom-out, fade-in, fade-out, and panning. For example, the shot may include a series of image frames captured concurrently in a basic capture unit.
According to an embodiment, when a video file is played back, the processor 120 may apply a dynamic effect corresponding to at least one playback mode during the static interval of the video file. For example, upon detecting an irregular frame in the static interval, the processor 120 may limitedly apply the dynamic effect to the irregular frame. For example, at the occurrence of shot transition by applying the dynamic effect to the static interval, the processor 120 may provide control to minimize shaking of a window region displayed to the display 160 with respect to a time axis. For example, the processor 120 may collect a center coordinate of a main region or a coordinate of the main region in an interval to which the shot transition is applied, and thus may apply smoothing to compensate for the shaking of the window region when the shot transition occurs. For example, the window region may include at least part of the display 160 on which information of the video file is displayed.
According to an embodiment, the processor 120 may provide control to apply a panning effect based on a shot length. For example, when the shot length is relatively long and a size of the main region is relatively great, the processor 120 may control the display 160 to apply the panning effect in order to provide dynamics.
According to an embodiment, when the video file is played back, the processor 120 may apply the dynamic effect to the static interval on a real time basis. For example, when the video file is played back, the processor 120 may detect the static interval by analyzing a image frame to be played back after a specific time elapses from a playback time of the video file. The processor 120 may apply at least one dynamic effect to the static interval while playing back the picture. For example, upon detecting the static interval while playing back the video file, the processor 120 may control the display 160 to display an object corresponding to the dynamic effect. The processor 120 may apply the dynamic effect to the static interval based on an input of selecting the object corresponding to the dynamic effect. For example, upon completion of the playback of the video file, the processor 120 may control the memory 130 to store shot information of the video file. For example, the shot information of the video file may include at least one dynamic interval included in the video file and dynamic effect information (e.g., a playback mode) applied to each static interval.
The memory 130 may include a volatile and/or nonvolatile memory. For example, the memory 130 may store instructions or data related to at least one different components of the electronic device 101. According to an embodiment, the memory 130 may store at least one video file that can be played back in the electronic device 101. For example, the memory 130 may store the shot information of the video file in a metadata format of the video file.
According to an embodiment, the memory 130 may store a software and/or a program 140. For example, the program 140 may include a kernel 141, a middleware 143, an Application Programming Interface (API) 145, or an application program (or “application”) 147. At least some of the kernel 141, the middleware 143, and the API 145 may be referred to as an Operating System (OS).
For example, the kernel 141 may control or manage system resources (e.g., the bus 110, the processor 120, the memory 130, etc.) used to execute an operation or function implemented in other programs (e.g., the middleware 143, the API 145, or the application program 147). In addition, the kernel 141 may also provide an interface capable of controlling or managing system resources by accessing individual components of the electronic device 101 in the middleware 143, the API 145, or the application program 147.
For example, the middleware 143 may play an intermediary role so that the API 145 or the application program 147 exchange data by communicating with the kernel 141. In addition, the middleware 143 may also handle one or more task requests received from the application program 147 according to a priority. For example, the middleware 143 may handle one or more task requests by assigning a priority that can be used in a system resource (e.g., the bus 110, the processor 120, the memory 130, etc.) of the electronic device 101 to at least one of the application programs 147. As an interface used by the application program 147 to control a function provided from the kernel 141 or the middleware 143, the API 145 may include, for example, at least one interface or function (e.g., command) for file control, window control, image processing, text control, or the like.
The input/output interface 150 may include various input/output circuitry and serve as an interface through which commands or data input from a user or a different external device can be delivered to different component(s) of the electronic device 101. For example, the input/output interface 150 may include various input/output circuitry, such as, for example, and without limitation, at least one physical button such as a home button, a power button, a volume control button, or the like. For example, the input/output interface 150 may also include a speaker for outputting an audio signal and a microphone for collecting the audio signal.
The display 160 may display a variety of content (e.g., text, image, video, icon, and/or symbol, etc.) to the user. For example, the display unit 160 may include a Liquid Crystal Display (LCD), a Light Emitting Diode (LED) display, an Organic Light-Emitting Diode (OLED) display, a Micro Electro Mechanical System (MEMS) display, or an electronic paper display, or the like, but is not limited thereto.
According to an embodiment, the display 160 may include a display panel and a touch panel. For example, the display 160 may receive a touch, gesture, proximity, or hovering input using an electronic pen or a portion of a user's body through the touch panel. For example, the display panel and the touch panel may overlap entirely or at least partially. For example, the display 160 may further include a pressure panel. For example, the display 160 may receive a pressure input caused by a portion of the user's body or an object through the pressure panel. For example, the display panel, the touch panel, and the pressure panel may overlap entirely or at least partially.
The communication interface 170 may include various communication circuitry and establish communication between the electronic device 101 and an external device (e.g., the first external electronic device 102, the second external electronic device 104, or the server 106). For example, the communication interface 170 may be coupled to the network 172 through wireless or wired communication to communicate with the external device (e.g., the second external electronic device 104 or the server 106).
According to an embodiment, the wireless communication may include cellular communication using at least one of LTE, LTE Advance (LTE-A), Code Division Multiple Access (CDMA), Wideband CDMA (WCDMA), Universal Mobile Telecommunications System (UMTS), Wireless Broadband (WiBro), Global System for Mobile Communications (GSM), and the like. According to an embodiment, as illustrated by the element 174 of
Each of the first and second external electronic devices 102 and 104 may be identical or different types of device with respect to the electronic device 101. According to various embodiments, all or some parts of operations performed in the electronic device 101 may be performed in one or a plurality of different electronic devices (e.g., the electronic devices 102 and 104, or the server 106).

According to an embodiment, the extraction module 122 may include a main region extractor (e.g., including processing circuitry and/or program elements) 181, a static interval detector (e.g., including processing circuitry and/or program elements) 182, and a motion extractor (e.g., including processing circuitry and/or program elements) 183. For example, the motion extractor 183 may be omitted.
According to an embodiment, the main region extractor 181 may include various processing circuitry and/or program elements and analyze at least one image frame in a video file to set a main region. For example, the main region extractor 181 may create a saliency map of the image frame using a deep learning scheme. The main region extractor 181 may set an ROI extracted using the saliency map as a main region of the image frame. For example, the main region extractor 181 may perform face recognition on the image frame to identify whether a face of an object exists in the image frame. The main region extractor 181 may set the main region such that a region recognized as the face is included in the image frame. For example, the main region extractor 181 may detect an object, of which a focus is set in the image frame, based on focus information of the video file. The main region extractor 181 may set the main region to include the object of which the focus is set. For example, the main region extractor 181 may obtain the focus information of the video file from additional information (e.g., exif) of the video file stored in the memory 130. For example, the main region extractor 181 may set the main region using all image frames of the video file or image frames included in a specific interval.
According to an embodiment, the static interval detector 182 may include various processing circuitry and/or program elements and set at least one static interval in the video file by analyzing a similarity between the image frames included in the video file. For example, when there are N image frames in the video file, the static interval detector 182 may divide the N image frames into M shots. The static interval detector 182 may set at least one shot, of which a similarity between image frames is greater than or equal to a reference value among the M shots, as a static interval for applying a dynamic effect. For example, N may include a constant greater than M. For example, the static interval detector 182 may recognize an interval, in which a change width between the image frames in the video file exceeds a designated change width (e.g., a reference change width), as one shot. In this case, the static interval detector 182 may be controlled not to apply an additional dynamic effect to a corresponding shot. For example, the static interval detector 182 may detect a static interval based on an overall feature value change pattern of the image frame. For example, the static interval detector 182 may detect the static interval based on a change pattern of a main region between the image frame. The change pattern of the main region may be determined based on at least one of a center coordinate, size, and location of the main region in the image frame.
According to an embodiment, the motion extractor 183 may include various processing circuitry and/or program elements and detect an object movement or a global motion from the video file. For example, when the location of the main region is changed in a state where the remaining regions (background) other than the main region of the image frame have similar feature values and a feature value change of the main region is less than a reference value, the motion extractor 183 may identify that the object is moved within the image frame. That is, the motion extractor 183 may detect a movement of the object based on a location change of the main region. For example, the motion extractor 183 may detect a global motion based on an overall feature value change pattern of consecutive video patterns included in the video file. For example, the motion extractor 183 may detect one global motion corresponding to a change pattern of the feature value when the change pattern of the feature value of the image frame is consistent.
According to an embodiment, the dynamic effect determining module 123 may include various processing circuitry and/or program elements and determine a playback mode of the static interval included in the video file. For example, the dynamic effect determining module 123 may determine at least one playback mode to be applied to the static interval based on at least one of the size and location of the main region of the image frame included in the static interval, a length of the static interval, a global motion, a playback pattern of the video file, a probability model, and a shot transition history. For example, the dynamic effect determining module 123 may determine at least one playback mode to be applied to the static interval based on a probability model and a type (e.g., a playback mode) of a shot disposed prior to the static interval. For example, when the dynamic effect determining module 123 identifies the playback mode to be applied to the static interval, a probability of transitioning to a corresponding playback mode may be decreased.
According to an embodiment, the playback control module 124 may include a transition controller (e.g., including processing circuitry and/or program elements) 191, a noise controller (e.g., including processing circuitry and/or program elements) 192, and a panning effect controller (e.g., including processing circuitry and/or program elements) 193. For example, the panning effect controller 193 may be omitted.
According to an embodiment, the transition controller 191 may include various processing circuitry and/or program elements and apply path smoothing for natural transition between shots. For example, when transitioning the shot, the transition controller 191 may correct a coordinate of a main region based on a movement of the main region and movement information of an object to mitigate a change width between image frames.
According to an embodiment, the noise controller 192 may include various processing circuitry and/or program elements and provide control to apply the dynamic effect based on a noise included in the static interval. For example, upon detecting an irregular frame in the static interval, the noise controller 192 may decide the irregular frame as the noise. Accordingly, the noise controller 192 may limitedly apply the dynamic effect to the irregular frame. For example, the noise controller 192 may analyze a similarity of the main region between image frames included in the static interval. The noise controller 192 may decide a image frame, of which a similarity of a main region is rapidly changed (e.g., decreased), as the irregular frame. When a similarly between image frames disposed prior to or next to the irregular frame is higher than a reference similarity and a length of the irregular frame is shorter than a reference length, the noise controller 192 may decide the irregular frame as the noise. For example, the noise controller 192 may decide the irregular frame based on movement information detected through a movement detection sensor (e.g., a gyro sensor).
According to an embodiment, the panning effect controller 193 may include various processing circuitry and/or program elements and provide control to apply the panning effect based on a shot length and a size of the main region included in the image frame. For example, when a length of image frames included in one shot exceeds a designated length (e.g., a reference length) and when the size of the main region exceeds a designated size (e.g., a reference size), the panning effect controller 193 may control the display 160 to apply the panning effect in order to provide dynamics to a corresponding shot interval.
According to an embodiment, the dynamic effect control module 125 may include various processing circuitry and/or program elements and control the applying of the dynamic effect when transitioning the shot. For example, the dynamic effect control module 125 may transiently add a transition effect such as a zoom effect (e.g., zoom-in or zoom-out) or a fading effect (e.g., fade-in or fade-out) when transitioning the shot. The dynamic effect control module 125 may determine a image frame to apply the transition effect based on a feature (e.g., a length and a similarity) of two adjacent shots. For example, the dynamic effect control module 125 may determine a image frame for introducing the transition effect in a previous shot and a image frame for ending the transition effect in the transitioned shot.
The processor 210, may include various processing circuitry that, for example, can control a plurality of hardware or software components connected to the processor 210 by operating an operating system or an application and can perform processing and calculation on various data. The processor 210, for example, may be a System on Chip (SoC). According to an embodiment, the processor 210 may further include a Graphic Processing Unit (GPU) and/or an Image Signal Processor (ISP). The processor 210 may include at least some (a cellular module 221) of the components shown in
The communication module 220 may have a configuration the same as or similar to that of the communication interface 170 shown in

According to an embodiment, the cellular module 221 can identify and authenticate the electronic device 201 in a communication network, using a subscriber identification module 224 (for example, a SIM card). According to an embodiment, the cellular module 221 can perform at least some of the functions that the processor 210 can provide. According to an embodiment, the cellular module 221 may include a Communication Processor (CP).
According to another embodiment, at least some (for example, two or more) of the cellular module 221, WiFi module 223, Bluetooth module 225, GNSS module 227, and NFC module 228 may be included in one Integrated Chip (IC) or IC package.

The RF module 229, for example, may include a transceiver, a Power Amp Module (PAM), a frequency filter, a Low Noise Amplifier (LNA), or an antenna. According to another embodiment, at least one of the cellular module 221, WiFi module 223, Bluetooth module 225, GNSS module 227, and NFC module 228 can transmit and receive RF signals through a separate RF module. The subscriber identification module 224, for example, may include a card including a subscriber identification module or an embedded SIM and may include unique identification information (for example, Integrated Circuit Card Identifier (ICCID) or subscriber information (for example, International Mobile Subscriber Identity (IMSI).
The memory 230 (for example, the memory 130 shown in
The sensor module 240, for example, can measure physical quantities or sense operation states of the electronic device 201 and can convert the measured or sensed information into electrical signals. The sensor module 240, for example, may include at least one of a gesture sensor 240A, a gyro sensor 240B, a barometer (e.g., atmospheric pressure) sensor 240C, a magnetic sensor 240D, an acceleration sensor 240E, a grip sensor 240F, a proximity sensor 240G, a color sensor 240H (for example, an RGB (red, green, blue) sensor), a biometric sensor 240I, a temperature/humidity sensor 240J, an illumination sensor 240K, and/or an Ultraviolet (UV) sensor 240M.

The sensor module 240 may further include a control circuit for controlling one or more sensors therein. In another embodiment, the electronic device 201 may further include a processor configured to control the sensor module 240, separately or as a part of the processor 210, whereby it is possible to control the sensor module 240 while the processor 210 is in a sleep state.
The input device 250, for example, may include various input circuitry, such as, for example, and without limitation, a touch panel 252, a (digital) pen sensor 254, a key 256, and/or an ultrasonic input device 258, or the like.

In operation 503, the electronic device may determine a partial region from an entire region of at least one image frame detected based on the change amount between the image frames. For example, the processor 120 may identify whether there is a series of image frames (a static interval), of which a similarity between image frames is greater than or equal to a reference value, in the video file. In the presence of the image frames (the static interval) of which the similarity between the image frames is greater than or equal to the reference value, the processor 120 may decide that the dynamic effect is applicable to at least part of the video file. In this case, the processor 120 may set the partial region from the entire region of the image frame as a main region for applying the dynamic effect. For example, the processor 120 may analyze the at least one image frame included in the static interval to create a saliency map. For example, the saliency map of the image frame may be created using a CNN scheme. The processor 120 may extract an ROI from the saliency map of the image frame. The processor 120 may set the ROI which is at least part of the image frame as the main region for applying the dynamic effect. For example, the processor 120 may set the main region to include a region in which a face is recognized in the image frame. For example, the processor 120 may set the main region to include an object of which a focus is set in the image frame. For example, the processor 120 may set the main region by analyzing all image frames included in the static interval or image frames having a specific interval.
In operation 505, the electronic device may determine at least one playback mode to apply the dynamic effect to the partial region. For example, the processor 120 may determine at least one playback mode to be applied to the main region of the static interval based on at least one of a size and location of the main region, a length of the static interval, a global motion, and a shot transition history and probability model of the electronic device 101. For example, the processor 120 may determine at least one playback mode to be applied to the static interval based on a playback mode used prior to the static interval and a transition probability corresponding to the playback mode. For example, in the absence of the shot transition history, the playback mode to be applied to the static interval may be determined based on any probability model. The processor 120 may update the probability model for determining the playback mode by analyzing an overall playback pattern of the video file.
In operation 507, the electronic device may display the partial region of at least one image frame to a display based on at least one playback mode. For example, the processor 120 may apply the dynamic effect to the static interval by playing back the video file based on the at least one playback mode. For example, the processor 120 may provide control not to apply the dynamic effect to an irregular frame so that the shot is naturally transitioned in the video file. The processor 120 may correct a coordinate of the main region based on a movement of the main region and movement information of an object to minimize shaking of a window region displayed to the display according to the shot transition.

In operation 603, the electronic device may compare a feature value of an ith static interval and a feature value of the fth image frame in the video file. For example, the processor 120 may compare an average of feature values of at least one image frame included in the ith static interval and the feature value of the fth image frame extracted in operation 601. For example, i denotes an index of a static interval included in the video file, and an initial value thereof may be set to 0.
In step 605, the electronic device may determine whether a change amount of feature values of the fth image frame and the ith static interval is less than a designated change amount (e.g., a reference change amount) based on a result of comparing feature values of the fth image frame and the ith static interval.
In operation 607, if the change amount of the feature values of the fth image frame and the ith static interval is less than the designated change amount, the electronic device may update the feature value of the ith static interval. For example, if the change amount of the feature value of the fth image frame and the ith static interval is less than the designated change amount, the processor 120 may decide that the fth image frame is included in the ith static interval. Accordingly, the processor 120 may update an average feature value of the ith static interval based on the feature value of the fth image frame.
In operation 615, the electronic device may determine whether the fth image frame is a last image frame included in the video file.
In operation 609, if the change amount of the feature value of the fth image frame and the ith static interval is greater than or equal to the designated change amount, the electronic device may store information of the ith static interval. For example, if the change amount of the feature value of the fth image frame and the ith static interval is greater than or equal to the designated change amount, the processor 120 may decide that the fth image frame is not included in the ith static interval. Accordingly, the processor 120 may control the memory 130 to store a image frame list included in the ith static interval.
In operation 611, the electronic device may update an index of the static interval. For example, the processor 120 may update the index of the static interval (e.g., i++) to identify whether there is a static interval different from the static interval in the video file.
In operation 613, the electronic device may set the feature value of the fth image frame as the feature value of the static interval including the updated index. For example, since up to an (f−1)th image frame is included in the ith static interval, the processor 120 may identify that the fth image frame is included in a next static interval. Accordingly, the processor 120 may set the feature value of the fth image frame as the average feature value of the static interval of the updated index.
In operation 615, the electronic device may identify whether the fth image frame is the last image frame included in the video file. For example, the processor 120 may identify whether the index of the fth image frame corresponds to a maximum index of the image frame included in the video file.
In operation 617, if the fth image frame is not the last image frame included in the video file, the electronic device may update the index of the image frame. For example, the processor 120 may update the index of the image frame (e.g., f++) to identify whether there is a image frame included in the static interval among other image frames included in the video file.
In operation 619, if the fth image frame is the last image frame included in the video file, the electronic device may set a main region for applying a dynamic effect in the static interval. For example, the processor 120 may set at least one main region to apply the dynamic effect using a saliency map of the image frame included in the static interval. For example, the processor 120 may set at least one main region to include a region in which a face is detected in the image frame included in the static interval. For example, the processor 120 may set at least one main region to include a region of which a focus is set in the image frame included in the static interval.
According to an embodiment, if the fth image frame is the last image frame included in the video file, the electronic device may remove the updated static interval including the fth image frame from the static interval list of the video file. For example, the static interval may include a series of image frames of which a similarity between the image frames is greater than or equal to a reference value. Accordingly, a static interval of an updated index including only the fth image frame cannot be set as the static interval of the video file.
According to an embodiment, if the fth image frame is the last image frame included in the video file, the electronic device may store at least one static interval information detected from the video file in a memory as information related to the video file. For example, the memory 130 may store static interval information of the video file in a metadata format.

For example, the static interval information corresponding to the video file may be detected before the playback of the video file as in operations 601 to 617 of
In the presence of the static interval information corresponding to the video file, in operation 707, the electronic device may determine whether a dynamic effect is applicable to a video file being displayed based on the static interval information corresponding to the video file. For example, the processor 120 may determine whether a image frame to be played back later by a specific time (e.g., 2 seconds) than the image frame being played back in the video file is included in the static interval.
In operation 705, in the absence of the static interval information corresponding to the video file, the electronic device may detect a change amount between image frames of the video file. For example, the processor 120 may detect a change amount of image frames to be played back later by a specific time (e.g., 2 seconds) than the image frame being played back in the image frame.
In operation 707, the electronic device may determine whether the dynamic effect is applicable to the video file based on the change amount between the image frames. For example, if a change amount of image frames to be played back later by a specific time (e.g., 2 seconds) than the image frame being played back in the video file is less than a designated change amount (e.g., a reference change amount), the processor 120 may set a series of image frames having a change amount less than the designated change amount as a static interval for applying the dynamic effect.
If the dynamic effect is not applicable to the video file, in operation 701, the electronic device may persistently play back the video file.
In operation 709, if the dynamic effect is applicable to the video file, the electronic device may set a main region to apply the dynamic effect to the static interval. For example, the processor 120 may set at least one main region to apply the dynamic effect based on at least one of a saliency map, face recognition information, and focus information of the image frame included in the static interval.
According to an embodiment, upon determining that the image frame to be played back later by a specific time than the image frame being played back is included in the static interval, the electronic device may determine a playback mode of the image frame to be played back.

According to an embodiment, if the dynamic effect is applicable to the video file, the electronic device may display a user interface corresponding to the dynamic effect to at least some regions of the video file being played back. For example, when the image frame included in the static interval is rendered and then played back, as illustrated in
According to an embodiment, when the dynamic effect is applied to at least one static interval while the video file is being played back, the electronic device may store information of at least one static interval detected from the video file as information related to the video file. For example, the memory 130 may store static interval information of the video file in a metadata format. For example, when the video file is completely played back and the dynamic effect is given to all shots included in the video file, the processor 120 may store information of applying the dynamic effect as the information related to the video file.

In operation 903, the electronic device may set at least one playback mode to be applied to a main region of a static interval based on the transition probability of at least one playback mode applicable to the static interval. For example, the processor 120 may determine at least one playback mode to be applied to the static interval based on a playback mode used prior to the static interval and the transition probability corresponding to the playback mode. For example, in the absence of the playback mode used prior to the static interval, the processor 120 may determine the playback mode to be applied to the static interval based on a probability model which is randomly set.
In operation 905, the electronic device may update a transition probability of at least one playback mode which is set to be applied to the main region of the static interval. For example, if a specific playback mode is frequently selected as the playback mode to be applied to the static interval, the playback of the static interval may become monotonous. Accordingly, the processor 120 may decrease the transition probability of at least one playback mode selected to be applied to the static interval.

In operation 1003, when the time for applying the dynamic effect arrives, the electronic device may output main region information based on a playback mode of the time for applying it. For example, the processor 120 may control the display 160 to display a main region of an image frame based on a playback mode corresponding to a image frame being played back. For example, the processor 120 may control the display 160 to display the main region in a zoom-in manner in the image frame being played back. For example, a zoom-in ratio of the main region may be set based on a size of the main region.
In operation 1005, the electronic device may determine whether to change the dynamic effect to be applied to the static interval. For example, when a plurality of playback modes are set in the static interval, the processor 120 may identify whether a time of applying another playback mode arrives.
Upon maintaining the dynamic effect to be applied to the static interval, in operation 1009, the electronic device may determine whether the static interval ends.
In operation 1007, upon deciding to change the dynamic effect to be applied to the static interval, the electronic device may output main region information based on the changed playback mode. For example, upon changing the playback mode to be applied to the static interval, the processor 120 may control the display 160 to update the display of the main region displayed to the display 160 so as to correspond to the changed playback mode.
In operation 1009, the electronic device may determine whether the static interval ends.

For example, the electronic device may additionally provide a panning mode 1109 for applying a panning effect based on a shot length. For example, the wide mode 1101, the intermediate display mode 1103, the intermediate zoom-in mode 1105, and the zoom-in mode 1007 may sequentially correspond to a size of the main region. For example, a main region corresponding to the wide mode 1101 may have a largest size, and a main region corresponding to the zoom-in mode 1107 may have a smallest size.
