An electronic device and a method for controlling the electronic device are provided. The electronic device includes a storage; a display; a communication interface configured to communicate with an external device to receive, from the external device, a video signal including a plurality of frames at a second transmission speed that is faster than a first transmission speed; and a processor configured to: control the communication interface to receive the plurality of frames transmitted at the second transmission speed and store the plurality of frames in the storage, identify features of a second frame among the plurality of frames to be played back after a first frame among the plurality of frames, and control the display to display the first frame based on the identified features of the second frame.

Various methods and systems are provided for accelerated image rendering with motion compensation. In one embodiment, a method comprises calculating motion between a preceding image frame and a target image frame to be rendered, rendering a small image with a size smaller than a target size of the target image frame based on the calculated motion, and generating the target image frame at the target size based on the small image, the calculated motion, and a reference image frame. In this way, high-quality image frames for a video stream may be generated with a reduced amount of rendering for each frame, thereby reducing the overall processing resources dedicated to rendering as well as the power consumption for image rendering.

A video processing apparatus and method is provided. The video processing apparatus divides video data and then processes a current divided area of the divided video data by referring to pixels in an adjacent divided area while processing the current divided area, thereby minimizing artifacts generation along a boundary between divided areas when the processed divided areas are subsequently merged.

Generally discussed herein are systems and apparatuses that are configured to and techniques for matching track fragments. According to an example, a technique can include receiving data indicating a first and second actual ToA of first and second SIGINT signals at a collector, estimating first and second sets of estimated ToAs of the first and second SIGINT signals at a collector, respectively, each of the first and second sets of estimated ToAs based on a different track fragment of a first plurality of track fragments active at the first time and a different track fragment of a second plurality of track fragments active at the second time, respectively, or matching a track fragment of the first plurality of track fragments with a track fragment of the second plurality of track fragments based on the first and second sets of estimated ToAs and the first and second actual ToAs.

The image processing apparatus processes an image signal obtained from an image pickup element using an image pickup optical system arranged to obtain directional traveling information of object image light corresponding to a pupil division area of a photographing lens. The apparatus includes: a unit of setting a focal position at which the refocused image is generated; and a unit of correcting an image signal of a defect pixel of the image pickup element using an image signal of other pixel. The apparatus determines the other pixel to be used for correcting the image signal of the defect pixel on the basis of the set focal position and the directional traveling information of the object image light.
