KSCAMERA_EXTENDEDPROP_FIELDOFVIEW2_CONFIGCAPS structure (ksmedia.h)

The KSCAMERA_EXTENDEDPROP_FIELDOFVIEW2_CONFIGCAPS structure defines the configuration capabilities of a camera's field of view (FoV).

Syntax

typedef struct tagKSCAMERA_EXTENDEDPROP_FIELDOFVIEW2_CONFIGCAPS {
  WORD  DefaultDiagonalFieldOfViewInDegrees;
  WORD  DiscreteFoVStopsCount;
  WORD  DiscreteFoVStops[360];
  ULONG Reserved;

Members

DefaultDiagonalFieldOfViewInDegrees

This is the default diagonal field of view in degrees. The DefaultDiagonalFieldOfViewInDegrees value must be equal to one of the values provided in the DiscreteFoVStops array.

DiscreteFoVStopsCount

This is a count of valid FoVStops in the DiscreteFoVStops[360] array, with value between 1 and 360. The array has room for maximum of 360 FoV values, but not all of them need to be populated.

For example, if three FoV values are supported: 110, 90, and 75 degrees

DiscreteFoVStopsCount = 3,
DiscreteFoVStops[0] = 110,
DiscreteFoVStops[1] = 90,
DiscreteFoVStops[2] = 75
DiscreteFoVStops[3] = 0 (not populated)
...
DiscreteFoVStops[359] = 0 (not populated)

DiscreteFoVStops[360]

This is an array of discrete FoV stops. Each element in the array represents a specific field of view setting in degrees. The values are populated in descending order.

Reserved

Reserved. Set to 0.
