3. Operating Modes
3.1 Video Timing
The video format mode on power-up is CIF 30fps by default. After power-up the mode can be changed by a serial interface to
write to the video_timing register. The frame/field rate is also programmable via the serial interface. Bit [3] of serial register [16]
selects between 30 and 25 frames per second for the CIF modes and 60/50 fields per second for the Digital and Analog Timing
modes. Please note that the sensor can exit low power in ANY of the available video modes.
The number of video lines in each frame is the same (320) for both the CIF modes. The slower frame rate (25 fps) is implemented
by simply extending the line period from 416 pixel periods to 500 pixel periods.
Table 3 details the setup for each of the video timing modes. A serial write to serial register [16] will force the contents of other
registers in the serial interface to change to the appropriate values, regardless of their present state. If for example a different
data output mode is required than the default for a particular video mode, a write to the appropriate register after the mode has
changed will restore the desired value.
