Detailed Description
The Dummy simulator image sensor class.
This works without any camera hardware, providing simulated test images or images loaded from DNG files through the same capture/getFrame interface as the real sensors. Its simulation capabilites are very limited, but sufficient for basic testing of UI or image processing functionality using x86 Qt simulators or arm emulators, such as the ones included in the Nokia Qt SDK. The sensor simulates frame duration, exposure, and gain.

| void FCam::Dummy::Sensor::capture | ( | const FCam::Shot & | ) | [virtual] |
Queue up the next shot.
Makes a deep copy of the argument.
Implements FCam::Sensor.
Definition at line 29 of file Sensor.cpp.
| void FCam::Dummy::Sensor::capture | ( | const std::vector< FCam::Shot > & | ) | [virtual] |
Queue up a burst of shots.
Makes a deep copy of the argument.
Implements FCam::Sensor.
Definition at line 51 of file Sensor.cpp.
| void FCam::Dummy::Sensor::stream | ( | const FCam::Shot & | s | ) | [virtual] |
Set a shot to be captured when the sensor isn't busy capturing anything else.
Makes a deep copy of the argument.
Implements FCam::Sensor.
Definition at line 85 of file Sensor.cpp.
| void FCam::Dummy::Sensor::stream | ( | const std::vector< FCam::Shot > & | ) | [virtual] |
Set a burst to be captured whenever the sensor isn't busy capturing anything else.
Makes a deep copy of the argument.
Implements FCam::Sensor.
Definition at line 103 of file Sensor.cpp.
| void FCam::Dummy::Sensor::stopStreaming | ( | ) | [virtual] |
Stop the sensor from streaming a shot or burst set with stream.
The sensor will continue to run. To turn off the sensor completely see Sensor::stop
Implements FCam::Sensor.
Definition at line 130 of file Sensor.cpp.
| void FCam::Dummy::Sensor::start | ( | ) | [virtual] |
Power up the sensor, image processor, and the FCam daemon This is done automatically when you call capture for the first time.
Implements FCam::Sensor.
Definition at line 137 of file Sensor.cpp.
| void FCam::Dummy::Sensor::stop | ( | ) | [virtual] |
Shut down the sensor, image processor, and the FCam daemon.
Call this to save power and/or processing cycles while your program is doing something unrelated to taking pictures.
Implements FCam::Sensor.
Definition at line 145 of file Sensor.cpp.
| virtual int FCam::Dummy::Sensor::maxExposure | ( | ) | const [inline, virtual] |
The maximum exposure time supported by this sensor.

| virtual float FCam::Dummy::Sensor::minGain | ( | ) | const [inline, virtual] |
| int FCam::Dummy::Sensor::rollingShutterTime | ( | const FCam::Shot & | ) | const [virtual] |
The time difference between the first line exposing and the last line in microseconds, for given shot parameters.
Implements FCam::Sensor.
Definition at line 171 of file Sensor.cpp.
| int FCam::Dummy::Sensor::shotsPending | ( | ) | const [virtual] |
How many shots are pending.
This includes frames in the frame queue, shots currently in the pipeline, and shots in the capture queue. Stop streaming (stopStreaming) and get frames (getFrame) until this hits zero to completely drain the system.
Implements FCam::Sensor.
Definition at line 200 of file Sensor.cpp.
| const FCam::Platform& FCam::Dummy::Sensor::platform | ( | ) | [inline, virtual] |
Access to the static platform data about this sensor.
Implements FCam::Sensor.
| FCam::Dummy::Frame FCam::Dummy::Sensor::getFrame | ( | ) |
Get the next frame.
We promise that precisely one frame will come back per time capture is called. A reference-counted shared pointer object is returned, so you don't need to worry about deleting it.
Reimplemented from FCam::Sensor.
