AR0833: 1/3.2-Inch 8 Mp CMOS Digital Image Sensor
System States
System States
The system states of the AR0833 are represented as a state diagram in Figure 4 and
described in subsequent sections.
The sensor's operation is broken down into three separate states: hardware standby,
software standby, and streaming. The transition between these states might take a
certain amount of clock cycles as outlined in Figure 4 and Figure 5 on page 13.
