Abstract: A method performed by an electronic device for generating a slow motion video includes obtaining plural image frames captured at a frame rate from a camera of the electronic device, detecting motion information in a first image frame from among the plural image frames, and performing an interpolation operation using one or more image frames from among the plural image frames. The one or more image frames are image frames obtained during a predetermined time after the first image frame in which the motion information is detected. A second image frame obtained before the first image frame in which the motion information is detected is discarded from the electronic device. A third image frame obtained after the predetermined time from the first image frame in which the motion information is detected is discarded from the electronic device.

Abstract: A method performed by user equipment (UE) for selecting a camera among multi-camera includes receiving a user instruction indicative of capturing of a scene and detecting Time of Flight (TOF) sensor information relating to scene. The TOF sensor information pertains to details relating to depth of each pixel in an image and an IR image of the scene. The method includes determining depth information of the scene based on the TOF sensor information and is indicative of a ROI in the scene, information about at least one object in the scene, and a type of the scene. The method includes determining scene information based on the depth information including identification information of the at least one object in the scene and distance information to the UE from each object from among the at least one object. The method includes selecting a camera, from among a plurality of cameras based on the scene information.

Abstract: In one or more embodiments, a method implemented in a multi camera device for a face detection management is disclosed. The method includes activating a second imaging sensor to capture a second preview frame of a scene at a higher zoom level than a first preview frame comprising at least one human with a face. The method includes detecting the face of the at least one human captured in the second preview frame upon capturing of the second preview frame. The method includes determining a set of facial co-ordinates associated with the face and a plurality of pre-defined parameters associated with the at least one human in the second preview frame. The method includes applying the set of facial co-ordinates and the plurality of pre-defined parameters to the first preview frame to generate a modified first preview frame. The method includes displaying the modified first preview frame as a camera preview.

Abstract: A method for enhancing image quality may be provided. The method may include receiving a plurality of input frames and metadata, and determining one or more feature scores for a received input frame from the plurality of input frames. The method may further include determining a parametric score for the received input frame based on an analysis of the one or more feature scores of the received input frame and the metadata. The method may include identifying one or more artifacts for correction in the received input frame based on the parametric score, and determining a strength of correction required for at least one identified artifact in the received input frame based on the parametric score, then applying the determined strength of correction to the received input frame. The method may further include performing multi-frame blending for a plurality of received input frames with applied determined strength of correction.

Abstract: Methods and systems for denoising media frames captured in low-light environment are provided. A method includes obtaining a media frame in pixel space using adaptive trimming of Fourier coefficients of an input media frame based on a threshold criterion, and obtaining a media frame in curvelet space by performing curvelet transform on the media frame in pixel space, extracting a texture frame based on texture details and a homogeneous frame based on homogeneous details, present in the media frame in pixel space, performing longitudinal and latitudinal filtering of the texture and homogeneous frames downscaled by a same factor, integrating the longitudinal and latitudinal filtered texture and homogeneous frames, upscaling the integration to obtain a curvelet media frame, and obtaining an output media frame by sharpening the curvelet media frame in multiple iterations based on partially sharpened curvelet media frames, the curvelet media frame, and the media frame in curvelet space.

Abstract: A method and a system for recording a Super Slow Motion (SSM) video in a portable electronic device are provided. A SSM video recording system detects presence of motion in the image frames captured by the image capturing device. Upon detecting the presence of motion, the SSM video recording system generates a trigger, subsequent to which, a first and fourth set of image frames for performing a frame skipping mechanism, and a second and third set of image frames for performing an interpolation mechanism are selected. The image frames of desired frame rate generated by performing the frame skipping mechanism and the interpolation mechanism are transmitted to an encoder in an order, for encoding and recording. The method and system allow SSM even in mid-tier and low-tier models of smartphones, without the need of expensive specialized image sensors.

Abstract: A method and an electronic device for capturing and generating a video content from an initial video is provided. The method includes displaying a selected region of interest (ROI) in the video at a high frame rate and high-resolution. The generated video content includes a first region and a second region. The first region is obtained by capturing frames in the ROI of the initial video at a first frame rate. The second region is obtained by capturing full video frames at a second frame rate. The first region and the second region are then combined thereby generating a slow motion video.
