Image composing method and device

Abstract

This invention discloses an image composing method and a device, in which, the method includes: A, obtaining the brightness information of each pixel point in each original image, B, picking up the HF component of related pixel points from the information, C, determining values of pixel points of the corresponding positions in the composed image, besides, LF components of related pixel points can be got at the same time picking up HF components in step B and LF components of related position pixel points in the composed image can be got according to the LF component of each point in the original image.

Description

technical field [0001] The invention relates to the field of information fusion, in particular to an image synthesis method and device. Background technique [0002] In recent years, image acquisition devices such as digital cameras, digital video cameras, and video cameras have been rapidly popularized, and required images can be obtained through these image acquisition devices. However, due to the depth of field of the image acquisition device, the acquired image will not be completely clear. Objects can only be clearly imaged on the imaging surface within a limited distance before and after the focus point of the image acquisition device. This distance that can form a clear image is the depth of field. Due to the small depth of field of the existing image acquisition equipment, it can only accurately focus on a distance in the scene, resulting in a clear image only at the focus position. For example, when focusing on the foreground, the obtained image has a clear foregro...
