propinfo
Property characteristics for image acquisition objects
Description
Examples
Create the video input object obj
.
obj = videoinput('winvideo',1);
Capture all property information for all properties.
info = propinfo(obj)
info = struct with fields: BayerSensorAlignment: [1×1 struct] DeviceID: [1×1 struct] DiskLogger: [1×1 struct] DiskLoggerFrameCount: [1×1 struct] ErrorFcn: [1×1 struct] EventLog: [1×1 struct] FrameGrabInterval: [1×1 struct] FramesAcquired: [1×1 struct] FramesAcquiredFcn: [1×1 struct] FramesAcquiredFcnCount: [1×1 struct] FramesAvailable: [1×1 struct] FramesPerTrigger: [1×1 struct] InitialTriggerTime: [1×1 struct] Logging: [1×1 struct] LoggingMode: [1×1 struct] Name: [1×1 struct] NumberOfBands: [1×1 struct] PreviewFullBitDepth: [1×1 struct] Previewing: [1×1 struct] ReturnedColorSpace: [1×1 struct] ROIPosition: [1×1 struct] Running: [1×1 struct] SelectedSourceName: [1×1 struct] Source: [1×1 struct] StartFcn: [1×1 struct] StopFcn: [1×1 struct] Tag: [1×1 struct] Timeout: [1×1 struct] TimerFcn: [1×1 struct] TimerPeriod: [1×1 struct] TriggerCondition: [1×1 struct] TriggerFcn: [1×1 struct] TriggerFrameDelay: [1×1 struct] TriggerRepeat: [1×1 struct] TriggersExecuted: [1×1 struct] TriggerSource: [1×1 struct] TriggerType: [1×1 struct] Type: [1×1 struct] UserData: [1×1 struct] VideoFormat: [1×1 struct] VideoResolution: [1×1 struct]
Access property information for a particular property.
info1 = propinfo(obj,'LoggingMode');
info1 = struct with fields: Type: 'string' Constraint: 'enum' ConstraintValue: {'memory' 'disk' 'disk&memory'} DefaultValue: 'memory' ReadOnly: 'whileRunning' DeviceSpecific: 0
Input Arguments
Video input object, specified as the output of the videoinput
function. obj
must be a 1-by-1 video input object.
Example: videoinput("matrox")
Name of a property, specified as a string or character vector. If
PropertyName
is a cell array of character vectors,
propinfo
returns a structure for each property,
stored in a cell array.
Example: "LoggingMode"
Data Types: char
| string
| cell
Output Arguments
Properties of the image object, returned as a structure or cell array of structures with the following fields.
Field Name | Description |
---|---|
| Data type of the property. Possible values are
|
| Type of constraint on the property value. Possible
values are |
| List of valid character vector values or a range of valid values. |
| Default value for the property. |
| Condition under which a property is read only:
