15:0
The Y coordinate of the upper-left corner of the FOV. If this register is set to an odd value, the next lower even value will be
used. Writes are synchronized to frame boundaries. Affected by Synchronize_Changes.
Causes a Bad Frame if written. Legal values: [0, 2004], even.
15:0
The X coordinate of the upper-left corner of the FOV. The value will be rounded down to the nearest multiple of 2 times the
column bin factor. Writes are synchronized to frame boundaries. Affected by Synchronize_Changes. Legal values: [0, 2750],
even.
Note: Set Column_Start such that it is in the form shown below, where n is an integer:
no bin
Bin 2x
Bin 4x
15:0
The height of the FOV minus one. If this register is set to an even value, the next higher odd value will be used. Writes are
synchronized to frame boundaries. Affected by Synchronize_Changes.
Causes a Bad Frame if written. Legal values: [1, 2005], odd.
15:0
The width of the field of view minus one. If this register is set to an even value, the next higher odd value will be used. In
other words, it should be (4*n*(Column_Bin + 1) - 1) for some integer n. Writes are synchronized to frame boundaries.
Affected by Synchronize_Changes. Causes a Bad Frame if written.
Legal values: [1, 2751], odd.
15:0
Extra time added to the end of each row, in pixel clocks. Incrementing this register will increase exposure and decrease frame
rate. Setting a value less than the minimum will use the minumum horizontal blank. The minimum horizontal blank depends
on the mode of the sensor. Writes are synchronized to frame boundaries. Affected by Synchronize_Changes. Causes a Bad
Frame if written. Legal values: [0, 4095].
15:0
Extra time added to the end of each frame in rows minus one. Incrementing this register will decrease frame rate, but not
affect exposure. Setting a value less than the minimum will use the minimum vertical blank. Writes are synchronized to
frame boundaries. Affected by Synchronize_Changes. Legal values: [8, 2047].
