Flash Control Output (Strobe Pin)

The OV5620 has a Strobe mode that allows it to work with

an external flash and LED.

Snapshot (Frame Exposure) Mode Timing

The OV5620 supports snapshot (frame exposure) mode.

Typically, the snapshot mode must work with the aid of an

external shutter.

The frame exposure pin, FREX (pin 10), is the snapshot

mode enable pin and the EXP_STB pin (pin 12) serves as

the sensor's exposure start trigger. When the external

master device asserts the FREX pin high, the sensor array

is quickly pre-charged and stays in reset mode until the

EXP_STB pin is pulled low (sensor exposure time can be

defined as the period between EXP_STB low to shutter

close). After the FREX pin is pulled low, the video data

stream is then clocked to the output port in a line-by-line

manner. After completing one frame of data output, the

OV5620 will output continuous live video data unless in

single frame transfer mode. Figure 17 shows detailed

timing of the Frame Exposure mode and Table 10 shows

the timing specifications for this mode.

When the OV5620 is working in snapshot mode, every

line is sampled at different times causing different dark

current levels line-by-line. To eliminate the dark current

difference, the OV5620 provides line optical black pixel

output. The difference in dark current can be calibrated

line-by-line.
