Detailed Description

Helper class that performs sensor-specific parameter computations.

Computation of sensor configuration parameters is a sensor specific operation. Each CameraHelper derived class computes the value of configuration parameters, for example the analogue gain value, using sensor-specific functions and constants.

Every subclass of CameraSensorHelper shall be registered with libipa using the REGISTER_CAMERA_SENSOR_HELPER() macro.

Macro Definition Documentation

REGISTER_CAMERA_SENSOR_HELPER

#define REGISTER_CAMERA_SENSOR_HELPER	(		name,
			helper
	)		static CameraSensorHelperFactory<helper> global_##helper##Factory(name);

Register a camera sensor helper with the camera sensor helper factory.

Parameters

[in]	name	Sensor model name used to register the class
[in]	helper	Class name of CameraSensorHelper derived class to register

Register a CameraSensorHelper subclass with the factory and make it available to try and match sensors.
