Claim Text:
1. An exposure parameter compensation method, for an imaging device, comprising the steps of: performing, by an image sensing element of the imaging device, a capture-mode image capturing step in accordance with a first exposure time and a second exposure time respectively based on a first light sensitivity and a predetermined time, thereby obtaining a first image and a second image based on the same first light sensitivity and the same predetermined time; performing, by a processor of the imaging device, an image operation on the first image and the second image to result in a difference image; replacing, by the processor of the imaging device, the first light sensitivity with a second light sensitivity, which is then recorded; and repeating the image capturing step in accordance with the first exposure time and the second exposure time based on the second light sensitivity and the predetermined time, until a brightness parameter of the difference image reaches a first threshold.
