  • Patent number: 10524645
    Abstract: In a multiple viewing elements endoscope, fuzziness and blur in the images due to movement of the endoscope is reduced by using flashing illuminators instead of continuous illumination. In one embodiment, LED illuminators are flashed at high intensity and for a very short duration. To address interlacing artifacts, LEDs are flashed once at the end of a field and again at the beginning of the following field to minimize the time difference between the capture of the two fields. In another embodiment, the LEDs are flashed once wherein the single flash overlaps the end of a field and the beginning of the following field. In some embodiments, still images may be captured with fine detail by pressing a button on the endoscope handle which activates the LEDs to flash along with the capture of an image. In one embodiment, pressing a button for still image capture results in the capture of two fields, each accompanied by a flash, which are interlaced to form a single still image frame.

    Abstract: An imaging device includes a light source, an image sensor, and a controller. Each pixel of the image sensor includes first and second accumulators and a discharger. The controller, while a component of light from the light source reflected by the surface of a target is incident on the image sensor, causes the accumulators to accumulate signal charge not discharged to the discharger, by setting the image sensor so that signal charge is discharged to the discharger, while a component having scattered inside the target is incident on the image sensor, causes the first accumulator to accumulate signal charge by setting the image sensor so that signal charge is not discharged to the discharger and signal charge is accumulated in the first accumulator, and causes the image sensor to generate first and second signals that are respectively based on signal charge accumulated in the first and second accumulators.
