Two and three dimensional near infrared subcutaneous structure imager using real time nonlinear video processing

An apparatus, comprising:

• a first camera configured to generate a composite first video signal;
• an analog non-linear processor operatively connected to the first camera, the analog non-linear processor comprising:
• a sync separator circuit configured to produce a burst sync and a composite sync to preserve the timing of all blanking level and sync pulse timing of the first video signal;
• a first user adjustment potentiometer configured to permit a user to adjust a voltage threshold;
• a clamp circuit configured to be activated by the burst sync and configured to set any portions of the first video signal below the threshold to a maximum dark level;
• a difference amplifier circuit configured to adjust the maximum dark level to a black level voltage;
• a second user adjustment potentiometer configured to permit the user to adjust gain such that portions of the first video signal which are above the threshold are adjusted to a maximum bright level to produce a processed video signal;
• an analog switch circuit configured to be actuated by the composite sync and configured to combine the processed video signal with a sync tip voltage to produce a second composite video signal;
• and
• a display, operatively connected to the analog non-linear processor, configured to display the second composite video signal.
