Partial Scan
The partial scan is a function for outputting part of a whole image as a region of interest on the whole image. Based on
the unit cell as the unit, continuous parts can be selected. Only rectangles can be selected. The screen cannot be cut in
convex and L shapes.
Vertical (Vertical Direction)
Cutting by Partial scan mode
Horizontal (Horizontal Direction)
The minimum unit size for partial scan is 64 pixels × 24 lines. The cut-out position can be set in unit of 4 pixels × 4 lines.
For high-speed scanning, set the maximum packet size.
When using multiple cameras at the same time, set a small packet size that falls within the set transmission rate band.
When using Partial scan mode, set Format7, Mode0.
Note
By selecting Partial scan mode, it is possible to set the maximum value of 752 pixels for the horizontal size of the image.
However, because the horizontal direction increases by a factor of 64, the image data is set to 768 pixels causing 16
pixel-wide completely black data to be output in the right edge of the image.
Although this completely black data will definitely appear in the right edge of the image when the horizontal size is set
to 752 pixels, this is not a malfunction because it is caused by a difference between the sensor's effective resolution and
the values set for the image size.
