+description: |-
|
|
+ The Sony IMX296 is a 1/2.9-Inch active pixel type CMOS Solid-state image
|
|
+ sensor with square pixel array and 1.58 M effective pixels. This chip
|
|
+ features a global shutter with variable charge-integration time. It is
|
|
+ programmable through I2C and 4-wire interfaces. The sensor output is
|
|
+ available via CSI-2 serial data output (1 Lane).

|
|
+ description:
|
|
+ The IMX296 sensor exists in two different models, a colour variant
|
|
+ (IMX296LQ) and a monochrome variant (IMX296LL). The device exposes the
|
|
+ model through registers, allowing for auto-detection with a common
|
|
+ "sony,imx296" compatible string. However, some camera modules disable the
|
|
+ ability to read the sensor model register, which disables this feature.
|
|
+ In those cases, the exact model needs to be specified as "sony,imx296ll"
|
|
+ or "sony,imx296lq".
