Changelog¶

Version 0.5.0¶

Add the possibility of limiting the maximum exposure time when using quarklib.isp.SimpleAutoExposure.

Improve the stability of the black level value when using quarklib.isp.calibrate_black_level().

Added quarklib.isp.calibrate_black_level() to auto calibrate black level.
Added a framework for taking a qamlib V4L2 control and making some higher level interactions possible, e.g. supporting different fixed-point formats.
Added a high-level API for interacting with camera controls through a wrapper quarklib.Camera. The API supports implicit conversions for fixed-point formats. The interface can be extended with custom controls.
Added quarklib.ccm.ColorChecker, quarklib.ccm.ColorReference to detect and measure ColorChecker targets.
Added: quarklib.ccm.Solver and perform_color_correction() to provide an interface for performing color correction.
Added quarklib.ccm.`linear_color_correction_rgb() which performs least squares color correction between two references using either a similarity or affine transform.

Only export auto exposure classes and functions if OpenCV is available.
Change quarklib.isp.create_trigger_sequence() to not do any sensor checks, since it should just check the availability of the trigger_sequence control

Added quarklib.image module with a function for saving PNM’s quarklib.image.save_pnm().
Added quarklib.isp module with a function for creation of a trigger sequnce.
Added quarklib.isp.AutoExposure, quarklib.isp.SimpleAutoExposure and quarklib.isp.one_shot_auto_exposure(), for doing auto exposure.
Added quarklib.get_logger() to get the logging.Logger that is used in quarklib.

quarklib.config.get() and quarklib.config.set() now create and accept simpler config with only the necessary information, and also improve the exception messages.

Fix quarklib.config.load() not defaulting to all (non-protected) controls when argument controls=None
