Abstract: A method for generating a high-dynamic-range (HDR) image using an imaging device is provided. The method includes capturing a long-exposure (LE) image, a short-exposure (SE) image, and an auto-exposure (AE) image of a scene, estimating motion information in the SE image and the LE image based on a reference image which is determined based on an image statistics parameter, aligning the SE image and the LE image using the motion information, generating a pixel-weight coefficient for each of the SE image, the LE image, and the AE image, generating an overlapped region mask corresponding to an overlapped region in each of the SE image, the LE image and the LE image, determining a modified pixel-weight coefficient in the overlapped region mask and correcting a brightness difference, and generating an HDR image from the SE image, the LE image and the AE image using the modified at least one pixel-weight coefficient.

Abstract: A method of an electronic device for automatically focusing on a moving object is provided. The method includes generating, by a processor, at least one focal code based on information comprising depth information of the moving object obtained using at least one previous position of the moving object, focusing, by the processor, on at least one portion of the moving object based on the at least one focal code, and capturing, by a sensor, at least one image of the moving object comprising the at least one portion of the moving object.
