WPD_EXPOSURE_METERING_MODES

WPD_EXPOSURE_METERING_MODES

The WPD_EXPOSURE_METERING_MODES enumeration type describes the metering mode to use when estimating exposure for still image capture by a device.

Syntax

  typedef enum WPD_EXPOSURE_METERING_MODES{
  WPD_EXPOSURE_METERING_MODE_UNDEFINED  =0,
  WPD_EXPOSURE_METERING_MODE_AVERAGE  =1,
  WPD_EXPOSURE_METERING_MODE_CENTER_WEIGHTED_AVERAGE  =2,
  WPD_EXPOSURE_METERING_MODE_MULTI_SPOT  =3,
  WPD_EXPOSURE_METERING_MODE_CENTER_SPOT  =4
};

Members

WPD_EXPOSURE_METERING_MODE_UNDEFINED

The metering mode is undefined.

WPD_EXPOSURE_METERING_MODE_AVERAGE

Use averaged exposure across the full image.

WPD_EXPOSURE_METERING_MODE_CENTER_WEIGHTED_AVERAGE

Use an averaged exposure, with the center of the image given more weight.

WPD_EXPOSURE_METERING_MODE_MULTI_SPOT

Use a multi-spot averaging technique.

WPD_EXPOSURE_METERING_MODE_CENTER_SPOT

Use a center-spot averaging technique.

Remarks

Indicates the metering mode of the device. This enumeration is used by the WPD_STILL_IMAGE_EXPOSURE_METERING_MODE property.
