AR0130: 1/3-Inch CMOS Digital Image Sensor

Features

Restart

To restart the AR0130 at any time during the operation of the sensor, write a “1” to the

Restart register (R0x301A[1] = 1). This has two effects: first, the current frame is inter-

rupted immediately. Second, any writes to frame-synchronized registers and the shutter

width registers take effect immediately, and a new frame starts (in video mode). The

current row completes before the new frame is started, so the time between issuing the

Restart and the beginning of the next frame can vary by about tROW.

Image Acquisition Modes

The AR0130 supports two image acquisition modes: video (also known as master) and

single frame.

Video

The video mode takes pictures by scanning the rows of the sensor twice. On the first

scan, each row is released from reset, starting the exposure. On the second scan, the row

is sampled, processed, and returned to the reset state. The exposure for any row is there-

fore the time between the first and second scans. Each row is exposed for the same dura-

tion, but at slightly different point in time, which can cause a shear in moving subjects as

is typical with electronic rolling shutter sensors.

Single Frame

The single-frame mode operates similar to the video mode. It also scans the rows of the

sensor twice, first to reset the rows and second to read the rows. Unlike video mode

where a continuous stream of images are output from the image sensor, the single-frame

mode outputs a single frame in response to a high state placed on the TRIGGER input

pin. As long as the TRIGGER pin is held in a high state, new images will be read out. After

the TRIGGER pin is returned to a low state, the image sensor will not output any new

images and will wait for the next high state on the TRIGGER pin.

The TRIGGER pin state is detected during the vertical blanking period (i.e. the FV signal

is low). The pin is level sensitive rather than edge sensitive. As such, image integration

will only begin when the sensor detects that the TRIGGER pin has been held high for 3

consecutive clock cycles.

During integration time of single-frame mode and video mode, the FLASH output pin is

at high.

Continuous Trigger

In certain applications, multiple sensors need to have their video streams synchronized

(E.g. surround view or panorama view applications). The TRIGGER pin can also be used

to synchronize output of multiple image sensors together and still get a video stream.

This is called continuous trigger mode. Continuous trigger is enabled by holding the

TRIGGER pin high. Alternatively, the TRIGGER pin can be held high until the stream bit

is enabled (R0x301A[2]=1) then can be released for continuous synchronized video

streaming.

If the TRIGGER pins for all connected AR0130 sensors are connected to the same control

signal, all sensors will receive the trigger pulse at the same time. If they are configured to

have the same frame timing, then the usage of the TRIGGER pin guarantees that all

sensors will be synchronized within 1 PIXCLK cycle if PLL is disabled, or 2 PIXCLK cycles

if PLL is enabled.
