Abstract: A method includes determining to set a face area as a current focus window when a face is detected in a to-be-photographed image, detecting a preset location in the face area, adjusting a width of the current focus window according to the preset location in the face area, stretching a length of the current focus window according to at least a first preset ratio and a second preset ratio, calculating at least a contrast value of an image in the first focus window and a contrast value of an image in the second focus window, and determining a final focus window according to the at least two contrast values. Therefore, the width of the focus window is reduced, so that such that the focus window is without background content.

Abstract: The present invention relates to an image splicing method and apparatus. The image splicing method includes: acquiring a first image and a second image; determining a to-be-processed region within the overlapping region, where a region within the overlapping region except the to-be-processed region is a remaining region; obtaining a weight value of each adjacent pixel pair of the remaining region; setting a weight value of an adjacent pixel pair within the to-be-processed region; determining a splicing path having the least seam line intensity of all splicing paths; and performing image splicing on the first image and the second image along the optimal seam line. According to the image splicing method and apparatus of the present invention, a seam line can be excluded from a to-be-processed region, so as to ensure that the to-be-processed region is spliced naturally and to improve subjective perception of a user in viewing an image.
