The diagram illustrates the use of ROI parameters A, B, I, and N, from the sen-
sor’s point of view. The sensor’s first (topmost) line has the address 0, the last
(lowermost) line has the address 6BD.
Range 0 (=off)or 1 (=on)
Default 0
Related Parameters A, B, D, N and I
Example A=0 start first AOI at the first line
B=5BD (0x5BD = 1469), starts second AOI at the 1470
th
line
D=1 enable double ROI mode
N=FF (0xFF = 255), reads 256 lines from each ROI, 512 lines in the out-
put image
I=1 read every line
Result: lines no 0 to 255 and no 1469 to 1724 of each image are read.
Exposure time (E)
The exposure time is a 32-bit value. Its time resolution depends on the prescaler
value K. For detailed information see chapter Timer prescaler value (K) on page
45.
Technically, the value range is 32 bit, whereas the useful exposure times should
be up to approx. 1 second.
Range Useful from 1 to approx. 50000 at K=A7, but not limited to that maximum.
Default 6BE (=1726)
