1 overview

1.1 introduction

The OVMed®-A1 is a high quality image output board with a stand-alone ISP SoC. It integrates a high-performance ISP

DSP solution, analog-digital converter, and support connection with host device for medical applications.

figure 1-1 OVMed-A1 DVP system diagram

It has one DVP port to output a video stream. The OVMed-A1 DVP has eight buttons to control the image effect, which

can be controlled through SCCB command and the configure tool. When changing the image effect, the changes will be

saved to the board.

When the OVMed-A1 DVP is rebooted, the image effect will be the same as the last time.

The OVMed-A1 DVP board is shown in figure 1-2.
