- +description: |-
- + The Sony IMX378 is a 1/2.3-inch CMOS active pixel digital image sensor
- + with an active array size of 4056H x 3040V. It is programmable through
- + I2C interface. The I2C address is fixed to 0x1A as per sensor data sheet.
- + Image data is sent through MIPI CSI-2, which is configured as either 2 or
- + 4 data lanes.
