  • Auto-exposure method for wireless capsule endoscope
    Patent number: 11730352
    Abstract: A method for image-capturing of an internal organ by a miniature imaging device, comprising: generating a light at a first light intensity on to a subject area of an internal organ and capturing an image of the subject area by a miniature imaging device configured under default exposure parameter values; computing a second light intensity and optimized exposure parameter values based on brightness of the captured image, an orientation, a position, and a motion of the miniature imaging device; and generating a light at the second light intensity on to the subject area and recapturing the image of the subject area by the miniature imaging device configured under the optimized exposure parameter values. The second light intensity and optimized exposure parameter values are derived by an ex vivo processing unit in wireless data communication with the miniature imaging device.
