In continuous mode video image capture, the TRIGGER signal should be held LOW or
“0.” To capture a still image, the sensor must first be put into snapshot mode by
programming a “1” in register 0x1E, bit 8. In snapshot mode, the sensor waits for a
TRIGGER signal (FRAME_VALID, LINE_VALID signals are LOW, pixel clock signal
continues). When the TRIGGER signal is received (active HIGH), one frame is read out (a
TRIGGER signal can also be achieved by programming a restart—for example, program
a “1” to bit 0 of Reg0x0B). The reset, readout timing for that frame will be the same as for
a continuous frame with similar register settings; the only difference is that only one
frame is read out. General timing for the snapshot mode is shown in Figure 15.
By setting bit 9 and 10 of Reg0x20 the line valid signal can get three different output
formats. The formats are shown when reading out four rows and two vertical blanking
rows (Figure 16). In the last format, the LINE_VALID signal is the XOR between the
continuously LINE_VALID signal and the FRAME_VALID signal.
