## Macros
#define | REGISTER_CAMERA_SENSOR_HELPER(name, helper)
| Register a camera sensor helper with the camera sensor helper factory.

## 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 )

Value:
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.
