title: Sony IMX258 13 Mpixel CMOS Digital Image Sensor

description: |-
  IMX258 is a diagonal 5.867mm (Type 1/3.06) 13 Mega-pixel CMOS active pixel
  type stacked image sensor with a square pixel array of size 4208 x 3120. It
  is programmable through I2C interface.  Image data is sent through MIPI
  CSI-2. The sensor exists in two different models, a standard variant
  (IMX258) and a variant with phase detection autofocus (IMX258-PDAF).
  The camera module does not expose the model through registers, so the
  exact model needs to be specified.
