The Omnivision OV02A10 is a low-cost, high performance, 1/5-inch, 2 megapixel
|
|
image sensor, which is the latest production derived from Omnivision's CMOS
|
|
image sensor technology. Ihis chip supports high frame rate speeds up to 30fps
|
|
@ 1600x1200 (UXGA) resolution transferred over a 1-lane MIPI interface. The
|
|
sensor output is available via CSI-2 serial data output.
