Pentax VNL-1170K image

Pentax High Definition video endoscope VNL-1590STi I recently purchased the Pentax High Definition video endoscope VNL-1590STi and I thought I would compare it to my older version video endoscope, model VNL-1170K. Both are high-quality. The VNL-1170K has a resolution of 720 x 480 pixels. The VNL-1590STi is being captured at 720p with a resolution of 1280 x 720 pixels.
