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 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.
