A digital dental image apparatus comprising: (A) an intra-oral image sensor configured to output a raw analog video signal; (B) a processing raw analog video signal (PRAVS) means for processing the raw analog video signal for optimum detection; (B) a digitizing, over sampling, and averaging (DOSA) means for digitizing, over sampling, and averaging the optimized analog video signal; and (C) a programmable control and signal processing (PCSP) means configured to generate a control signal to control an over sampling rate of the (DOSA) means. The PCSP means is configured to process the DOSA video signal, and configured to output the processed DOSA video signal to an output network interface.
