Table 46 : Exposure Related Registers

Coarse MSB exposure value

302

The maximum allowable coarse

exposure setting is filed length

dependent. We provide the

maximum coarse exposure settings

for each of the standard video

modes.

NTSC = 260

PAL = 310

CIF (25 & 30 fps) = 318

QCIF (25 & 30 fps) = 158
