Programmable partial scan
Address：0x70, Bit：0, Value:0 and Address：0x81, Bit：0, Value:1
A range arbitrary from 50 lines to 1236 lines can be read. The frame rate can be raised to 183fps or less by
skipping it at high speed excluding an effective area.
When the frame rate of a partial scanning exceeds it when the shutter mode is switched from normality
(internal synchronization) to the partial scanning mode, more high-speed than the setting of the speed of
the shutter it is changed at the speed of the shutter matched to the frame rate.
･Starting position of effective line Address：0x84, Bit：0 to 7, and Address:0x85, Bit:0 to 2, Value:0 to 1186
Starting position (Partial V Start) of an effective line can be set.
･Number of effective lines
Address：0x88, Bit：0 to 7, and Address:0x89, Bit:0 to 2, Value:50 to 1236
Number (Partial Height) of effective lines can be set.
The frame rate is obtained in the following calculations.
