The invention belongs to the technical field of image processing, and particularly discloses a multi-exposure image integration method based on bilateral filtering. The method comprises the steps that (1) three static pictures of the same scene of different exposures are inputted; (2) the originally inputted pictures are divided into two parts of a detail layer and a basic layer based on a bilateral filter and then the detail layer and the basic layer are processed respectively; (3) weight of the basic layer is estimated by applying a Gaussian curve and weight is updated by applying picture saturation information; (4) an intermediate integration picture is preliminarily integrated by the updated weight; (5) the maximum value of each detail layer is obtained to act as a detail picture as for the detail layer; and (6) a final integration picture is obtained by synthesizing the obtained intermediate integration picture and the detail picture. Calculation complexity is low, and the details of the picture can be fully protected in the integration picture and the picture is enabled to be more natural in the aspect of color. The multi-exposure image integration method based on bilateral filtering can be widely applied to the field of image enhancement or cameras.
