Abstract: Provided is a video correction method comprising: extracting a common feature point from a number of video frames corresponding to a correction window size; extracting a trace of the feature point from the video frames; calculating an average value of the trace in the video frames; extracting a stabilized trace from a circular queue circular queue buffer using the trace and the average value; and applying a repositioning operation and a perspective warping operation to the video frames based on the stabilized trace to generate a stabilized video.

Abstract: The present disclosure relates to a camera device. The camera device and an electronic device including the same according to an embodiment of the present disclosure include: a color camera; an IR camera; and a processor configured to extract a first region of a color image from the color camera, to extract a second region of an IR image from the IR camera, to calculate error information based on a difference between a gradient of the first region and a gradient of the second region, to compensate for at least one of the color image and the IR image based on the calculated error information, and to output a compensated color image or a compensated IR image.
