| 14 | The Omnivision OV8856 is a high performance, 1/4-inch, 8 megapixel, CMOS | |
| 15 | image sensor that delivers 3264x2448 at 30fps. It provides full-frame, | |
| 16 | sub-sampled, and windowed 10-bit MIPI images in various formats via the | |
| 17 | Serial Camera Control Bus (SCCB) interface. This chip is programmable | |
| 18 | through I2C and two-wire SCCB. The sensor output is available via CSI-2 | |
| 19 | serial data output (up to 4-lane). | |
