Partial scan is the mode, which increases the frame rate by reducing the number of read-out vertical lines.
The upper part and the lower part of the image are omitted, and only the central portion of the vertical
lines is read out. When gain is set at over +6dB, V shading may become visible.
V-Shading portion can be deleted by setting data “1” to address 057 which eliminates the top 35 lines.
Effective lines setting and readout position in partial scan mode
(1) In partial scan mode, effective lines and readout position can be set with remote control.
(a) Effective lines setting: By setting address 049, 255 line to 681 line can be set per 3 lines steps.
