The OV426 is a single chip solution for small medical image sensors like the OV6946 and OV6948. The OV426 provides an integrated analog-to-digital data conversion using a built-in A/D converter (ADC), black level calibration (BLC), AEC/AGC and a final digital video parallel output (DVP). The OV426 supports a standard SCCB interface to communicate with the system and manipulate the above mentioned functions.

During operation, the OV426 decodes the proprietary analog output from the OV6946 and digitizes it by an ADC. The generated digital signals will then be processed by a digital signal processor (DSP) and finally, standard DVP outputs are sent out.
