Abstract
An imaging device having an in vivo CMOS image sensor, at least one illumination source and a controller. The controller controls the illumination source to illuminate for a first period and to be shut off for a subsequent period.
Claims10
A method for in vivo imaging comprising the steps of:
- illuminating with an at least one white LED a site in vivo for at least one period of illumination;
- providing pixels of an in vivo image sensor with at least one period of illumination during which the pixel circuitry is inactivated and at least one subsequent dark period with the at least one white LED turned off during which integration of dark signals occurs for each pixel for a period of time measured as time elapsed between two consecutive readout pulses applied to the pixel;
- successively reading out and then immediately resetting each pixel during the dark period to obtain an image frame;
- and
- eliminating dark signal noise from each image frame.
