The Omnivision OV4689 is a high performance, 1/3-inch, 4 megapixel
|
||
|
|
image sensor. Ihis chip supports high frame rate speeds up to 90 fps
|
||
|
|
at 2688x1520 resolution. It is programmable through an I2C
|
||
|
|
interface, and sensor output is sent via 1/2/4 lane MIPI CSI-2
|
||
|
|
connection.
