+description: |-
|
|
+ The Sony IMX500 is a stacked 1/2.3-inch CMOS digital image sensor and inbuilt
|
|
+ AI processor with an active array CNN (Convolutional Neural Network) inference
|
|
+ engine. The native sensor size is 4056H x 3040V, and the module also contains
|
|
+ an in-built ISP for the CNN. The module is programmable through an I2C
|
|
+ interface with firmware and neural network uploads being made over SPI. The
|
|
+ default I2C address is 0x1A, with an address of 0x10 being selectable via
|
|
+ SLASEL. The module also has a second I2C interface available with a fixed
|
|
+ address of 0x36. Image data is sent through MIPI CSI-2, which is configured
|
|
+ as either 2 or 4 data lanes.
