AR0130: 1/3-Inch CMOS Digital Image Sensor
Output Data Format
Output Data Format
The AR0130 image data is read out in a progressive scan. Valid image data is surrounded
by horizontal and vertical blanking (see Figure 8). The amount of horizontal row time (in
clocks) is programmable through R0x300C. The amount of vertical frame time (in rows)
is programmable through R0x300A. LINE_VALID (LV) is HIGH during the shaded region
of Figure 8. Optional Embedded Register setup information and Histogram statistic
information are available in first 2 and last row of image data.

Readout Sequence
Typically, the readout window is set to a region including only active pixels. The user has
the option of reading out dark regions of the array, but if this is done, consideration must
be given to how the sensor reads the dark regions for its own purposes.
