The invention relates to the technical field of mobile communication, in particular to a high dynamic range video image acquisition method. The method comprises the following steps: S1, acquiring a first preview image and a second preview image; S2, dividing the first preview image into first sub-regions, and obtaining a first exposure parameter; dividing the second preview image into a second sub-region, and obtaining a second exposure parameter; S3, determining a first exposure image based on the first exposure parameter, and determining a second exposure image based on the second exposure parameter; S4, synthesizing the first exposure image into a first synthesis image, and synthesizing the second exposure image into a second synthesis image; S5, performing alignment synthesis processing on the first synthesis image to generate a first image; performing high dynamic range image synthesis processing on the second synthesis image to generate a second image; and performing alignment synthesis processing on th
