2 system level description
2.1 overview
The OV5647 is a low voltage, high performance, 5 megapixel CMOS image sensor that provides 2592x1944 video output
using OmniBSI™ technology. It provides multiple resolution raw images via the control of the serial camera control bus
or MIPI interface.
The OV5647 has an image array capable of operating up to 15 fps in 2592x1944 resolution with user control of image
quality, data transfer, camera functions through the SCCB interface. The OV5647 uses innovative OmniBSI technology
to improve the sensor performance without the physical and optical trade-off.
For customized application, the OV5647 includes a one-time programmable (OTP) memory.
2.2 architecture
The OV5647 sensor core generates streaming pixel data at a constant frame rate, indicated by HREF and VSYNC.
figure 2-1 shows the functional block of the OV5647 image sensor. figure 2-2 shows an example application of the
OV5647 sensor.
