OVMed high-resolution image sensor for endoscopes
Summary
The OAH0428 bridge chip, specifically developed for 720x720 resolution compatibility, enables analogue-to-digital conversion and the flexibility for a variety of analogue and digital inputs and outputs. Additionally, we have built in a high level of flexibility with the OAH0428 bridge chip.” The OH0FA’s resolution of 720x720 represents an increase when compared with the previous generation image sensor, the OVM6946, at 400x400. Special features of the OAH0428 companion chip include HDR, auto-start, pseudo-global shutter, enhanced NIR sensitivity, and various security functions. Exposure time and gain settings can be sent from an external SPI control, automatically by the OAH0428 internal AEC/AGC or manually by the host. OmniVision’s OVMed product line consists of medical-grade, trusted components that undergo comprehensive certification, qualification and testing.
