Abstract
A system, method, scope device, and camera control module device for a video endoscopy system, to enable scopes to operate with a rolling shutter-type image sensor. With selected pulsing of a strobe light, subset image data from adjacent rolling-shutter frames is selected, gain compensated for missing light and combined into a new single video frame.
Claims14
A video endoscopy system comprising:
- an imager that generates a first frame and a second frame of a plurality of video frames using a rolling shutter;
- a light source that generates pulses of light based on a desired frequency;
- an exposure controller that adjusts a duration and position in time of the pulses based on the desired frequency during the first and second frames;
- and
- a digital line gain module that selectively applies a digital line gain to at least a portion of the first frame and a portion of the second frame, the digital line gain applied to pixels on one or more lines of the portions of the first and second frames, based on a gap time between the first frame and the second frame and the duration and position in time of the pulses.
