Partial Scan - Sony XCG-H280E Technical Manual

Partial Scan

Partial Scan is a function for outputting a user-defined region within the overall image area. The cut-out region for
partial scan is defined by Offset X and Offset Y (which indicate the start point for cutting) as well as Width and Height
(which indicate the area). Contiguous blocks of minimum areas can be selected to define regions. However, the defined
region must be a rectangle. T- and L-shaped regions are invalid. When Vertical Binning or/and Horizontal Binning are
active, the pixels defined by Width, Height, OffsetX, and OffsetY are those after pixel binning.

Notes
• When setting Partial Scan mode, observe the following conditions.
Width + OffsetX
Height + OffsetY
• Be aware that the frame rate increases for vertical cut-outs, while the frame rate remains unchanged for horizontal
cut-outs.
• In 4-channel sensor reading, the closer to the center the reading position, the more the frame rate will be improved.
While keeping Height unchanged, OffsetY that provides the maximum frame rate can be obtained with the formula
below:
OffsetY = (MaxHeight – Height)/2
Be sure that MaxHeight is 1440 with Vertical Binning Off and 720 with it On.
