getdata
Type String Data Type
'uint8'
Unsigned 8-bit integer
'uint16'
Unsigned 16-bit integer
'uint32'
Unsigned 32-bit integer
'single'
Single precision
'double'
Double precision
'native'
Uses native data type. This is the default.
If type is not specified, 'native' is used as the default. If there is no
MATLAB data type that matches the object’s native data type,
getdata
chooses a MATLAB data type that preserves numerical accuracy. For
example, the components of 12-bit RGB color data would each be
returned as
uint8 data.
data = getdata(obj,n ,type,format) returns n frames of data
associated with the video input object
obj,wherefor mat is one of the
text strings in the following table that specify the MATLAB format
of
data.
Format
String Description
'numeric'
Returns data as an H-by-W-by-B-by-F array. This is
the default format if none is specified.
'cell'
Returns data as an F-by-1 cell array of H -by-W-by-B
matrices
[data,time] = getdat a(...) returns ti me, an F-by-1 matrix, w h ere
F is the number of frames returned in
data.Eachelementoftime
indicates the relative time, in seconds, of the corresponding frame in
data, relative to the first trigger.
time = 0 is defined as the point at w hich data logging begins. When
data logging b egins, the object’s
Logging property is se t to 'On'. time
