Region of Interest (ROI)
It is possible to reduce unnecessary data as well as increasing frame rate by cutting out an arbitrary
area in the effective pixel scope.
The arbitrary area can be simply cut by specifying "starting point" and "effective pixels".
※
The above image shows the positional relationship with the origin (0,0) in the upper left corner.
Please specify the
“
origin
”
by selecting the location of Effective Horizontal Origin and the Effective
Vertical Origin.
Please specify the
“
Effective Pixels
”
by selecting the Effective Vertical Pixels and the Effective
Horizontal Pixels.
Please use multiples of 4 when specifying values.
The range of values of the horizontal direction is 320~2448, and the range of values of the horizontal
direction is 4~2048.
For instance, if specify the effective horizontal starting point as 128, the effective vertical starting point
as 64, the effective horizontal pixel as 1280, and the effective vertical pixel as 640, then the cut area is
shown as below. In such a case, the frame rate is around 186fps (reference value).
