Abstract: An image generation method includes: determining at least one first image capture setting and at least one second image capture setting; controlling an image capture device to generate a plurality of first successive captured images for a capture trigger event according to the at least one first image capture setting and generate a plurality of second successive captured images for the same capture trigger event according to the at least one second image capture setting. Variation of the at least one first image capture setting is constrained within a first predetermined range during generation of the first successive captured images. Difference between the at least one first image capture setting and the at least one second image capture setting is beyond the first predetermined range. Variation of the at least one second image capture setting is constrained within a second predetermined range during generation of the second successive captured images.
