Benefits of technology

[0011] Some embodiments of the present invention include a device and method for operating an in vivo imaging device wherein the illumination produced by the device may be varied in intensity and/or du

Problems solved by technology

One of the limitations of electronic imaging sensors is that they may have a limited dynamic range.
Thus, when the imaged field of view includes both dark and bright parts or imaged objects, the limited dynamic range of the imaging sensor may result in underexposure of the da
