摘要： The present invention is directed to a light sensitivity calibration method and an imaging device. An exposure step is performed to obtain a light sensitivity according to a predetermined time. A time adjustment step is performed to adjust the predetermined time according to the light sensitivity, thereby obtaining an adjusted time. The predetermined time is replaced with the adjusted time and the exposure and time adjustment steps are repeatedly performed, until the adjusted time converges within a predetermined range.

摘要： The present invention is directed to an exposure parameter compensation method and an imaging device. A capture-mode image capturing step is performed to obtain a first image and a second image according to a first exposure time and a second exposure time respectively based on a first light sensitivity and a predetermined time. The first image and the second image are operated on to result in a difference image. The first light sensitivity is replaced with a second light sensitivity, which is then recorded.
