## Variables
const Control< bool > | libcamera::controls::AeEnable
| Enable or disable the AE.
const Control< bool > | libcamera::controls::AeLocked
| Report the lock status of a running AE algorithm.
const std::array< const ControlValue, 4 > | libcamera::controls::AeMeteringModeValues
| List of all AeMeteringMode supported values.
const std::map< std::string, int32_t > | libcamera::controls::AeMeteringModeNameValueMap
| Map of all AeMeteringMode supported value names (in std::string format) to value.
const Control< int32_t > | libcamera::controls::AeMeteringMode
| Specify a metering mode for the AE algorithm to use. The metering modes determine which parts of the image are used to determine the scene brightness. Metering modes may be platform specific and not all metering modes may be supported.
const std::array< const ControlValue, 4 > | libcamera::controls::AeConstraintModeValues
| List of all AeConstraintMode supported values.
const std::map< std::string, int32_t > | libcamera::controls::AeConstraintModeNameValueMap
| Map of all AeConstraintMode supported value names (in std::string format) to value.
const Control< int32_t > | libcamera::controls::AeConstraintMode
| Specify a constraint mode for the AE algorithm to use. These determine how the measured scene brightness is adjusted to reach the desired target exposure. Constraint modes may be platform specific, and not all constraint modes may be supported.
const std::array< const ControlValue, 4 > | libcamera::controls::AeExposureModeValues
| List of all AeExposureMode supported values.
const std::map< std::string, int32_t > | libcamera::controls::AeExposureModeNameValueMap
| Map of all AeExposureMode supported value names (in std::string format) to value.
const Control< int32_t > | libcamera::controls::AeExposureMode
| Specify an exposure mode for the AE algorithm to use. These specify how the desired total exposure is divided between the shutter time and the sensor's analogue gain. The exposure modes are platform specific, and not all exposure modes may be supported.
const Control< float > | libcamera::controls::ExposureValue
| Specify an Exposure Value (EV) parameter. The EV parameter will only be applied if the AE algorithm is currently enabled.
const Control< int32_t > | libcamera::controls::ExposureTime
| Exposure time (shutter speed) for the frame applied in the sensor device. This value is specified in micro-seconds.
const Control< float > | libcamera::controls::AnalogueGain
| Analogue gain value applied in the sensor device. The value of the control specifies the gain multiplier applied to all colour channels. This value cannot be lower than 1.0.
const std::array< const ControlValue, 3 > | libcamera::controls::AeFlickerModeValues
| List of all AeFlickerMode supported values.
const std::map< std::string, int32_t > | libcamera::controls::AeFlickerModeNameValueMap
| Map of all AeFlickerMode supported value names (in std::string format) to value.
const Control< int32_t > | libcamera::controls::AeFlickerMode
| Set the flicker mode, which determines whether, and how, the AGC/AEC algorithm attempts to hide flicker effects caused by the duty cycle of artificial lighting.
const Control< int32_t > | libcamera::controls::AeFlickerPeriod
| Manual flicker period in microseconds. This value sets the current flicker period to avoid. It is used when AeFlickerMode is set to FlickerManual. To cancel 50Hz mains flicker, this should be set to 10000 (corresponding to 100Hz), or 8333 (120Hz) for 60Hz mains. Setting the mode to FlickerManual when no AeFlickerPeriod has ever been set means that no flicker cancellation occurs (until the value of this control is updated). Switching to modes other than FlickerManual has no effect on the value of the AeFlickerPeriod control.
const Control< int32_t > | libcamera::controls::AeFlickerDetected
| Flicker period detected in microseconds. The value reported here indicates the currently detected flicker period, or zero if no flicker at all is detected. When AeFlickerMode is set to FlickerAuto, there may be a period during which the value reported here remains zero. Once a non-zero value is reported, then this is the flicker period that has been detected and is now being cancelled. In the case of 50Hz mains flicker, the value would be 10000 (corresponding to 100Hz), or 8333 (120Hz) for 60Hz mains flicker. It is implementation dependent whether the system can continue to detect flicker of different periods when another frequency is already being cancelled.
const Control< float > | libcamera::controls::Brightness
| Specify a fixed brightness parameter. Positive values (up to 1.0) produce brighter images; negative values (up to -1.0) produce darker images and 0.0 leaves pixels unchanged.
const Control< float > | libcamera::controls::Contrast
| Specify a fixed contrast parameter. Normal contrast is given by the value 1.0; larger values produce images with more contrast.
const Control< float > | libcamera::controls::Lux
| Report an estimate of the current illuminance level in lux. The Lux control can only be returned in metadata.
const Control< bool > | libcamera::controls::AwbEnable
| Enable or disable the AWB.
const std::array< const ControlValue, 8 > | libcamera::controls::AwbModeValues
| List of all AwbMode supported values.
const std::map< std::string, int32_t > | libcamera::controls::AwbModeNameValueMap
| Map of all AwbMode supported value names (in std::string format) to value.
const Control< int32_t > | libcamera::controls::AwbMode
| Specify the range of illuminants to use for the AWB algorithm. The modes supported are platform specific, and not all modes may be supported.
const Control< bool > | libcamera::controls::AwbLocked
| Report the lock status of a running AWB algorithm.
const Control< Span< const float, 2 > > | libcamera::controls::ColourGains
| Pair of gain values for the Red and Blue colour channels, in that order. ColourGains can only be applied in a Request when the AWB is disabled.
const Control< int32_t > | libcamera::controls::ColourTemperature
| Report the current estimate of the colour temperature, in kelvin, for this frame. The ColourTemperature control can only be returned in metadata.
const Control< float > | libcamera::controls::Saturation
| Specify a fixed saturation parameter. Normal saturation is given by the value 1.0; larger values produce more saturated colours; 0.0 produces a greyscale image.
const Control< Span< const int32_t, 4 > > | libcamera::controls::SensorBlackLevels
| Reports the sensor black levels used for processing a frame, in the order R, Gr, Gb, B. These values are returned as numbers out of a 16-bit pixel range (as if pixels ranged from 0 to 65535). The SensorBlackLevels control can only be returned in metadata.
const Control< float > | libcamera::controls::Sharpness
| A value of 0.0 means no sharpening. The minimum value means minimal sharpening, and shall be 0.0 unless the camera can't disable sharpening completely. The default value shall give a "reasonable" level of sharpening, suitable for most use cases. The maximum value may apply extremely high levels of sharpening, higher than anyone could reasonably want. Negative values are not allowed. Note also that sharpening is not applied to raw streams.
const Control< int32_t > | libcamera::controls::FocusFoM
| Reports a Figure of Merit (FoM) to indicate how in-focus the frame is. A larger FocusFoM value indicates a more in-focus frame. This singular value may be based on a combination of statistics gathered from multiple focus regions within an image. The number of focus regions and method of combination is platform dependent. In this respect, it is not necessarily aimed at providing a way to implement a focus algorithm by the application, rather an indication of how in-focus a frame is.
const Control< Span< const float, 9 > > | libcamera::controls::ColourCorrectionMatrix
| The 3x3 matrix that converts camera RGB to sRGB within the imaging pipeline. This should describe the matrix that is used after pixels have been white-balanced, but before any gamma transformation. The 3x3 matrix is stored in conventional reading order in an array of 9 floating point values.
const Control< Rectangle > | libcamera::controls::ScalerCrop
| Sets the image portion that will be scaled to form the whole of the final output image. The (x,y) location of this rectangle is relative to the PixelArrayActiveAreas that is being used. The units remain native sensor pixels, even if the sensor is being used in a binning or skipping mode.
const Control< float > | libcamera::controls::DigitalGain
| Digital gain value applied during the processing steps applied to the image as captured from the sensor.
const Control< int64_t > | libcamera::controls::FrameDuration
| The instantaneous frame duration from start of frame exposure to start of next exposure, expressed in microseconds. This control is meant to be returned in metadata.
const Control< Span< const int64_t, 2 > > | libcamera::controls::FrameDurationLimits
| The minimum and maximum (in that order) frame duration, expressed in microseconds.
const Control< float > | libcamera::controls::SensorTemperature
| Temperature measure from the camera sensor in Celsius. This is typically obtained by a thermal sensor present on-die or in the camera module. The range of reported temperatures is device dependent.
const Control< int64_t > | libcamera::controls::SensorTimestamp
| The time when the first row of the image sensor active array is exposed.

| List of all AfMode supported values.
const std::map< std::string, int32_t > | libcamera::controls::AfModeNameValueMap
| Map of all AfMode supported value names (in std::string format) to value.

| Map of all AfRange supported value names (in std::string format) to value.
const Control< int32_t > | libcamera::controls::AfRange

const std::array< const ControlValue, 2 > | libcamera::controls::AfSpeedValues
| List of all AfSpeed supported values.
const std::map< std::string, int32_t > | libcamera::controls::AfSpeedNameValueMap
| Map of all AfSpeed supported value names (in std::string format) to value.
const Control< int32_t > | libcamera::controls::AfSpeed
| Control that determines whether the AF algorithm is to move the lens as quickly as possible or more steadily. For example, during video recording it may be desirable not to move the lens too abruptly, but when in a preview mode (waiting for a still capture) it may be helpful to move the lens as quickly as is reasonably possible.
const std::array< const ControlValue, 2 > | libcamera::controls::AfMeteringValues
| List of all AfMetering supported values.
const std::map< std::string, int32_t > | libcamera::controls::AfMeteringNameValueMap
| Map of all AfMetering supported value names (in std::string format) to value.
const Control< int32_t > | libcamera::controls::AfMetering
| Instruct the AF algorithm how it should decide which parts of the image should be used to measure focus.
const Control< Span< const Rectangle > > | libcamera::controls::AfWindows
| Sets the focus windows used by the AF algorithm when AfMetering is set to AfMeteringWindows. The units used are pixels within the rectangle returned by the ScalerCropMaximum property.
const std::array< const ControlValue, 2 > | libcamera::controls::AfTriggerValues
| List of all AfTrigger supported values.
const std::map< std::string, int32_t > | libcamera::controls::AfTriggerNameValueMap
| Map of all AfTrigger supported value names (in std::string format) to value.
const Control< int32_t > | libcamera::controls::AfTrigger
| This control starts an autofocus scan when AfMode is set to AfModeAuto, and can also be used to terminate a scan early.
const std::array< const ControlValue, 3 > | libcamera::controls::AfPauseValues
| List of all AfPause supported values.
const std::map< std::string, int32_t > | libcamera::controls::AfPauseNameValueMap
| Map of all AfPause supported value names (in std::string format) to value.
const Control< int32_t > | libcamera::controls::AfPause
| This control has no effect except when in continuous autofocus mode (AfModeContinuous). It can be used to pause any lens movements while (for example) images are captured. The algorithm remains inactive until it is instructed to resume.
const Control< float > | libcamera::controls::LensPosition
| Acts as a control to instruct the lens to move to a particular position and also reports back the position of the lens for each frame.

const Control< int32_t > | libcamera::controls::AfState
| Reports the current state of the AF algorithm in conjunction with the reported AfMode value and (in continuous AF mode) the AfPauseState value. The possible state changes are described below, though we note the following state transitions that occur when the AfMode is changed.

| List of all HdrMode supported values.
const std::map< std::string, int32_t > | libcamera::controls::HdrModeNameValueMap

| Control to set the mode to be used for High Dynamic Range (HDR) imaging. HDR techniques typically include multiple exposure, image fusion and tone mapping techniques to improve the dynamic range of the resulting images.
const std::array< const ControlValue, 4 > | libcamera::controls::HdrChannelValues
| List of all HdrChannel supported values.
const std::map< std::string, int32_t > | libcamera::controls::HdrChannelNameValueMap
| Map of all HdrChannel supported value names (in std::string format) to value.
const Control< int32_t > | libcamera::controls::HdrChannel
| This value is reported back to the application so that it can discover whether this capture corresponds to the short or long exposure image (or any other image used by the HDR procedure). An application can monitor the HDR channel to discover when the differently exposed images have arrived.
const Control< float > | libcamera::controls::Gamma
| Specify a fixed gamma value. Default must be 2.2 which closely mimics sRGB gamma. Note that this is camera gamma, so it is applied as 1.0/gamma.
