These registers control how much noise filtering is done for Y/U/V channels. The bigger the value is, the more noise filtering at the expense
of video details.

Vertical line [9:8]
This status register is only updated when a status request is initiated via bit 0 of subaddress 24h.
Vertical line [9:0] represent the detected a total number of lines from the previous frame. This can be used with nonstandard video signals
such as a VCR in trick mode to synchronize downstream video circuitry.
NOTE: This register is not double buffered.
Since this register is a double byte register it is necessary to "capture" the setting into the register to ensure that the value is not updated
between reading the lower and upper bytes. In order to cause this register to "capture" the current settings bit 0 of I2C register 24h (Status
Request) should be set to a 1. Once the internal processor has updated this register bit 0 of register 24h will be cleared, indicating that both
bytes of the vertical line count register have been updated and can be read. Either byte may be read first since no further update will occur
until bit 0 of 24h is set to 1 again.
