David Plowman 4a748394e5 libcamera: pipeline: raspberrypi: Implementation of digital zoom
During configure() we update the ScalerCropMaximum to the correct
value for this camera mode and work out the minimum crop size allowed
by the ISP.

Whenever a new ScalerCrop request is received we check it's valid and
apply it to the ISP V4L2 device. When the IPA returns its metadata to
us we add the ScalerCrop information, rescaled to sensor native
pixels.

libcamera for the Raspberry Pi

Raspberry Pi provides a fully featured pipeline handler and control algorithms (IPAs, or "Image Processing Algorithms") to work with libcamera. Support is included for all existing Raspberry Pi camera modules.

libcamera for the Raspberry Pi allows users to:

  1. Use their existing Raspberry Pi cameras.
  2. Change the tuning of the image processing for their Raspberry Pi cameras.
  3. Alter or amend the control algorithms (such as AGC/AEC, AWB or any others) that control the sensor and ISP.
  4. Implement their own custom control algorithms.
  5. Supply new tunings and/or algorithms for completely new sensors.

How to install and run libcamera on the Raspberry Pi
