4 is a flowchart illustrating a method for controlling an electronic device according to various embodiments of the present disclosure.

In operation 401, the electronic device 101 may acquire a plurality of images. The electronic device 101 may acquire a plurality of images through the included camera module. In more detail, the electronic device 101 may capture an image at a preset period, and the preset period may be preset to enable natural animation reproduction. Alternatively, the electronic device 101 may acquire a plurality of images captured over time from another electronic device. For example, the electronic device 101 may acquire a plurality of images from another electronic device through an included communication module. In various embodiments of the present disclosure, the electronic device 101 may stabilize each of the acquired images. The electronic device 101 may register at least one of the plurality of images in the first frame to correct the alignment of the objects. The electronic device 101 may correct irregular camera movement caused by hand shake or the like based on the stabilization algorithm. The stabilization algorithm may be optical image stabilization or software-based digital image stabilization or a combination of the optical image stabilization and software-based digital image stabilization. According to one embodiment of the present invention, the transition from the previous frame to the current frame is identified using function detection for all frames and a Lucas-Kanade optical flow. The transformation may be performed based on three parameters including, but not limited to, dx (movement in the x direction), dy (movement in the y direction), and da (angle). The transformation parameters may be accumulated to obtain a trajectory of x, y and angle in each frame. The trajectory can be smoothed using a Kalman filter. In addition, a modified transform parameter may be applied to the frames, which will stabilize the images. When the plurality of images are stabilized, registration of the plurality of images, that is, each frame may be performed. During registration of frames, transform parameters for all frames can be detected using feature extraction and light flow. Stabilization may be performed on each of the sequences of frames by rotating back to the first frame using the identified configurations of transformation parameters. Similarly, a depth map may also be registered in a first frame of the sequence of frames to correct an alignment error.

In operation 403 , the electronic device 101 may display a first image among a plurality of images. Here, the first image may be an image initially displayed during reproduction, for example, may be the first image among a plurality of images, but the first image is not limited thereto. The animation image corresponding to the first image may be an animation in which the first image is initially displayed and then other images are sequentially displayed. Accordingly, the first image may be called a still image.

In operation 405 , the electronic device 101 detects a first event set to start playing the animation image of the first object of the first image. For example, the electronic device 101 may detect a touch input to the first object or a user's gaze to the first object. Alternatively, the electronic device 101 may detect the first event based on an analysis result of at least one of the acquired preview image, the motion information of the electronic device 101, and the acquired sound information. Here, the first event may be to designate a specific object of the first image, that is, a still image. Alternatively, the first event may be input of a specific sound. Alternatively, the first event may be to apply a specific motion to the electronic device. Those skilled in the art will readily understand that there is no limitation as long as the electronic device can detect an event through various modules. The electronic device 101 may acquire the first event based on an external input. For example, the electronic device 101 may acquire the first event by displaying a graphic user interface that induces the input of the first event after generating the animation image. Alternatively, the electronic device 101 may analyze the animation image and acquire the first event based on the analysis result. For example, the electronic device 101 may analyze the animation image and determine that the animation image is an animation in which a face object smiles. The electronic device 101 may set capturing a smile of the viewer of the animation image as a first event that is an animation image reproduction condition corresponding to a face object. Alternatively, the electronic device 101 may simply detect an object whose motion exceeds a preset threshold among the animation image as the first event detection. That is, when an animation image reproduction request is received, the electronic device 101 may reproduce an animation image only for an object exceeding a threshold value among the animation images.

When user designation is detected, the electronic device 101 may determine which object is designated by performing object segmentation, and the segmentation process will be described in more detail later.

In operation 407 , the electronic device 101 may reproduce an animation for the first object in response to the designation of the first object. In this case, the electronic device 101 may maintain the display in the first image for the remaining area except for the first object. Accordingly, the electronic device 101 may reproduce the animation image so that only some objects in the still image are animated. The electronic device 101 may obtain a target object from each of the plurality of images by segmenting each of the plurality of images. The electronic device 101 may reproduce an animation image for a specific object by sequentially changing the animation image reproduction target object to an object in each of the plurality of images and displaying the object. According to an embodiment, the electronic device 101 may reproduce an animation image for a specific object by replacing the target object with a tracked area and displaying it while tracking the target object in another image.

According to various embodiments of the present disclosure, the electronic device 101 may set an event for each object of the still image. For example, the still image may include a first object and a second object. The electronic device 101 may acquire a first event for starting the animation of the first object and acquire a second event for starting the animation of the second object. Here, the first event and the second event may be different. Accordingly, when the first event is detected, the electronic device that reproduces the animation message may reproduce the animation of the first object. In this case, the objects of the still image other than the first object may be maintained without change in display. That is, the reproducing electronic device may reproduce only the animation of the first object in response to the detection of the first event. Meanwhile, when the second event is detected, the reproducing electronic device may reproduce only the animation of the second object.

The electronic device 101 may store the first event in association with the object of the animation image. For example, the electronic device 101 may include information on the first event in metadata of the animation image. Alternatively, the electronic device 101 may store the animation image by mapping the first event. The information on the first event may include hardware information capable of detecting the event and content detected by the hardware.

As described above, the electronic device 101 according to various embodiments of the present disclosure may display an animation effect while reproducing an animation image for a specified object while maintaining the display of the remaining area. In addition, the electronic device 101 may set an event, which is a condition for starting playback for each animation, and, when a specific event is detected, may play an animation image of an object corresponding to the detected event.

In operation 501, the electronic device 101 may acquire a plurality of images. For example, the electronic device 101 may acquire a first image and a second image each including the first object and the second object.

In operation 503, the electronic device 101 may generate an animation image corresponding to each of at least one object of the first image among the plurality of images. For example, the electronic device 101 may segment each of the plurality of images to identify the first object and the second object from each of the plurality of images. In addition, the electronic device 101 may generate an animation image for the first object and an animation image for the second object. The electronic device 101 may perform segmentation using image information such as a depth map or a color value.

In operation 505, the electronic device 101 may acquire an event for starting playback of an animation image for each object. The electronic device 101 may obtain an event through image analysis or may obtain an event through detected information or an external input. For example, the electronic device 101 may obtain event information for each object as shown in Table 1.

event first object Hardware Information: Camera Module
Event Details: Detection of smiling faces second object Hardware Information: Accelerometer
Event Details: Right movement of the electronic device

As shown in Table 1, the event information may include at least one of hardware information capable of acquiring an event and event content.

Meanwhile, the electronic device 101 may set a plurality of events even for one object. For example, as shown in Table 1, the electronic device 101 may additionally designate the designation of the first object as the event while designating the event content for the first object as the detection of a smiling face.

In operation 507, the electronic device 101 may associate and store an event for reproduction for each object. The electronic device 101 may later detect an event using stored information while displaying a still image, and reproduce an animation image of an object corresponding to the detected event. Alternatively, the electronic device 101 may transmit stored information to another electronic device, and the other electronic device may detect an event using the stored information and reproduce an animation image of an object corresponding to the detected event.

For example, the electronic device 101 may acquire a preview image through the camera module and detect the user's smile by analyzing the preview image. The electronic device 101 may reproduce the animation for the first object in response to the detection of the smiley face, and maintain the display of the second object in the still image as it is. The electronic device 101 may detect the movement of the electronic device 101 through the acceleration sensor, and the electronic device 101 may detect movement information in the right direction. The electronic device 101 may reproduce the animation for the second object in response to detection of the movement in the right direction, and the first object may maintain the display in the still image as it is.

The first image 610 may be a portrait of an expressionless face, and the second image 620 may be a portrait of a smiling face. The first image 610 may include a face object 611 and a background object 612 , and the second image 620 may include a face object 621 and a background object 622 .

The electronic device 101 may store information on the first event in response to a “face object”.

Referring to FIG. 7B , during reproduction, the electronic device 101 may acquire a preview image in operation 750 .

The animated images are stored as image metadata, and include a sequence of frames corresponding to the still image, a depth map of the still image, and audio information corresponding to one or more objects present in the image. The image metadata may be generated by multiplexing the data as described above using the multiplexer 2030 .

21 is a detailed block diagram of an electronic device for recording an animation corresponding to a still image, according to an embodiment of the present invention.

The image capture module 2101 includes an image capture device capable of capturing a sequence of frames. The sequence of frames may be a single image or video file. The sequence of frames is captured using at least one of a camera and a video camera. Also, the sequence of frames may be extracted from a video file already stored in the memory device or captured. In one embodiment of the present invention, the image capture device is coupled to a burst shot module. The burst shot module internally generates a burst shot command. This burst shot command triggers the capture of a sequence of camera frames. The number of images in the burst and the time gap between the capture of any two consecutive frames are predefined based on the duration of the animation of the image.

The depth prediction module 2102 is another input module, and may determine a depth map of the captured images. The depth map information may also be derived from the sequence of captured frames. Accordingly, the depth prediction module 2102 may be connected to the burst shot module. The depth prediction module 2102 may calculate a depth map corresponding to every image in the burst shot. The depth map may be determined using time of flight based depth sensors, a stereo camera, infrared projection, focus bracketing, and a sequence of frames captured using the camera.

Hereinafter, various methods of predicting the depth will be described.

Time of flight (TOF)-based depth sensors include a general TOF sensor, a modulated light source such as a laser or LED, and an array of pixels each capable of detecting the phase of the input light. ) and a general optical system for focusing the light to the sensor. The light is provided as a modulation envelope by rapidly turning the light source on and off. Distance/depth measurements are accomplished by measuring the phase of the modulation envelope of the transmitted light received at the pixel array.

A stereo camera computes a depth map based on the difference between two images captured at the same time from two different camera sensors. The movement of other objects in the scene across the stereo images is inversely proportional to their depth. The depth is based on stereo matching, which is the process of estimating a 3D model of the scene by taking two or more images, detecting matching pixels in the images, and converting the 2D positions into 3D depths. is calculated as

According to the infrared projection method, a known structured light pattern can be projected into the scene and inference depth from a variant of the pattern.

In focus bracketing, depth is obtained by capturing multiple images of a scene at different focal lengths. Based on the sharpness changes across these images, a depth map is computed.

Alternatively, the electronic device may also estimate depth information from visual camera frame data using a segmentation algorithm using color, texture, shape, or other image-related attributes. According to an embodiment of the present invention, the depth map is independently acquired for every frame. In another embodiment, the depth map is calculated for the first frame. In addition, the depth map for the remaining frames is added to the sequence of frames using a particle filter and a state of the art mechanism such as shape/silhouette/blob tracking. It may be obtained by tracking the depth map of the first frame across

The microphones 2103 and the sound recorder 2104 may be other types of input modules used to record audio information corresponding to one or more objects present in the image.

The captured frames and depth map are provided to the correction module 2105 . According to an embodiment of the present invention, each still image and a depth map are registered in the first frame to correct alignment errors. Also, the correction algorithm may be executed to correct irregular camera movement due to hand shake or the like. The stabilization algorithm may be optical image stabilization or software-based digital image stabilization or a combination of the optical image stabilization and software-based digital image stabilization. In one embodiment of the present invention, the correction module 2105 detects the transformation from the previous frame to the current frame using feature detection for all frames and a Lucas-Kanade optical flow. The transformation consists of three parameters: dx (movement in x direction), dy (movement in y direction), and da (angle). The transformation parameters are accumulated to obtain a trajectory of x, y and angle in each frame. The trajectory is smoothed using a Kalman filter. The modified transform is applied to the frames. This stabilizes the images. Once the frames have stabilized, registration is performed. During registration of frames, transform parameters for all frames are detected using feature extraction and light flow. Then, all the frames are twisted back to the first frame using the configuration of the transformation parameters.

The processor includes an event detection module 2106 . The event detection module 2106 analyzes the images to identify the occurrence of the event. The general triggers may include at least one of touch, gaze, anger, speaking, shaking, and gesture, and the event is laughter, eye blinking, the number of depth layers, and the like. In one embodiment, the images are analyzed for the presence of a face/smile. For the given image, facial features and orientation are calculated with the Active Appearance Model (AAM). Based on the AAM points, a mesh is defined and other features of the face such as nose, lips, and mouth are identified. Using these points, identify the presence of laughter. This information is stored in the metadata of the file. The registered images and the registered depth map are provided to the multiplexer. The multiplexer 2030 multiplexes the image, depth map, and sound streams (from multiple microphones) into image metadata. Meanwhile, the event detection module 2106 may be implemented with various hardware such as a microphone, a proximity sensor, and a motion information sensor rather than image analysis, and the processor may detect an event based on a signal from the hardware.

22 is a block diagram of an electronic device for reproducing a recorded animation of at least one object in a part of a still image corresponding to the animation image, according to an embodiment of the present invention.

The electronic device according to an embodiment of the present invention includes a demultiplexer 2201 , an animation rendering module 2202 , a display 2203 , and a sound generating module 2204 . The demultiplexer 2201 may demultiplex the composite file generated by the multiplexer. For example, when an animation image having the format shown in FIGS. 15 and 16 is received, the demultiplexer 2201 may demultiplex the animation image into a plurality of regions. The demultiplexed sound streams in the animated image may be transmitted to the sound generating module 2204 . The images and the depth map are provided to the animation rendering module 2202 which regenerates the animation in the image in response to event detection. The display 2203 may reproduce the animation rendered by the animation rendering module 2202 .

23 is a detailed block diagram of an electronic device that reproduces the animated image according to an embodiment of the present invention.

The demultiplexer 2300 parses the image metadata and extracts the image, depth map and sound streams. The sound stream is sent to the source separation module 2306 , while the image and depth map are sent to the envelope extraction module 2302 . The event corresponding to the animation is extracted by the demultiplexer 2301 . The event is provided to the event detection module 2301 . The event detection module 2301 may activate hardware corresponding to the event, and may detect the event based on a signal from the activated hardware. The information on the event may be transmitted to the envelope detection module 2302, and the information on the event may include, for example, coordinates of the event. The coordinates of the event may be the touch point coordinates in the image touched by the user to interact with the image.

In one embodiment of the present invention, if the still image has a human smile, this information is stored in the file at the time of capturing the still image. When the image is viewed, this information is detected and provided to the user as an indication of the presence of the smile (eg a smile icon). The user interaction may be "if the user laughs, the animated image laughs again". The envelope detection module 2302 receives the coordinates of the event for the event detection module 2301 and segments the desired object from the depth map. A useful method for depth-based segmentation is used for segmentation of images. Segmentation of the image helps to identify the foreground and background objects. This module also analyzes the captured file and all frames that are part of the segmented depth to extract the envelope of the moving object. The identified object region is transmitted to the sound localization module 2307 . The occlusion detection module 2303 identifies the presence of occlusion based on the segmented images. The occlusion is the overlap of the two distinct objects in the image. The occlusion correction module 2304 removes the occluded region and compensates the occluded region based on information present in adjacent frames of the sequence of frames. The blending module 2305 copies an area corresponding to the segmented images from every frame using a depth map, and pastes it into a first frame in the sequence of frames. The pasted boundary regions are blended to ensure a seamless transition to create a composite image. According to a preferred embodiment of the present invention, blending methods such as alpha blending, Laplacian blending, Poisson blending or other states in the existing method are used to generate the composite image. Each composite image as described above is rendered on the display 2309 to reproduce the same motion of the object that was present at the time of the capture.

The source separation module 2306 filters each sound source along with direction information from multiple sound streams recorded using multiple microphones. This is achieved using an analysis based on interaural time differences (ITDs), interaural intensity differences (IIDs) and interaural phase differences (IPDs). can be The sound localization module 2307 localizes the sound sources based on the extracted envelope position. Localization of the sound in the context of the present invention means identifying a sound emanation from the region using the sound direction information. If there is a sound corresponding to the user touch object, the corresponding sound is played using the speaker 2308 .
