Core Class
The core class of capture settings is:
CaptureSetting
- The
CaptureSettingclass represents various capture settings of camera devices. - Supported capture settings are provided as derived classes of the
CaptureSettingclass.
Basic Usage
All the supported capture settings have corresponding classes derived from the CaptureSetting class. This section shows you how to use manage individual capture settings using the classes. You can also manage multiple capture settings at the same time. Code examples in this section show how to manage aperture value but you can manage other settings in similar ways.
Get Individual Capture Settings
Follow the steps below to get current value of specified capture setting.
- Generate an object of the class corresponding to the capture setting you want
- Use the
getCaptureSettingsmethod with the object
The following example shows how to get current aperture value using FNumber object.
std::unique_ptr<FNumber> fNumber(new FNumber());
cameraDevice->getCaptureSettings(std::vector<CaptureSetting*>{fNumber.get()});
std::cout << "Current Value: " << fNumber->toString() << std::endl;
List Available Setting Values
Follow the steps below to get a list of available values for individual capture settings.
- Generate an object of the class corresponding to the capture setting you want
- Use the
getCaptureSettingsmethod with the object - Use the
getAvailableSettingsmethod of the object
The following example shows how to get a list of available aperture values using FNumber object.
std::unique_ptr<FNumber> fNumber(new FNumber());
cameraDevice->getCaptureSettings(std::vector<CaptureSetting*>{fNumber.get()});
const std::vector<const CaptureSetting*>& availableFNumberSettings =
fNumber->getAvailableSettings();
for (auto setting : availableFNumberSettings) {
std::cout << "Available Setting: " << setting->toString() << std::endl;
}
Set Individual Capture Setting
Follow the steps below to set value of specified capture setting.
- Select a class and its field corresponding to the value you want to set
- Use the
setCaptureSettingsmethod with the field
The following example shows how to set the aperture value to 5.6 using FNumber object.
const FNumber* fNumber = FNumber::F5_6;
cameraDevice->setCaptureSettings(std::vector<const CaptureSetting*>{fNumber});
