TM/TMC-4200CL Series Progressive Scan Cameras
6.3.2 Programmable Scan Area
In Programmable Scan Area Mode, users can specify both the start point of the active scan area and the
total active lines through the serial communication commands. The area selected by users is transferred
out line by line. The rest of the lines are dumped out using the fast dump function of the CCD. The
frame rate in this mode varies according to the selected active area. When the active area starts from x
row, and the active lines are y lines, the frame rate can be calculated using the following formulas.
Where,
For a color CCD, the upper-left Bayer pattern changes, depending on the start point location. If the start
point is the odd row, the upper-left Bayer pattern is G. In RG if the start point is the even row, the upper-
left bayer pattern is B in BG.
