3.0 Frame Capture Modes
There exists two frame capture modes:
1) Continuous Frame Rolling Shutter mode (CFRS)
2) Single Frame Rolling Shutter mode (SFRS)
The sensor can be put into either one of the aforemen-
tioned modes by writing either “1” or “0” to Bit 6 of
ture Mode Control Register, (Table 31), on page

3.1 Continuous Frame Rolling Shutter capture
The default mode of image capture is the “Continuous
Frame Rolling Shutter” capture mode (CFRS). This
mode will yield frame rates up to 10fps at 13.5 MHz
MCLK. In this mode the image integration and row read-
out take place in parallel. While a row of pixels is being
read out, another row(s) are being integrated. Readout
of each row follows the Integration of that row. There-
fore the Integration of the rows are staggered out due to
the Readout of sequential rows occurring one after the
other (see
page
the first row of the second frame automatically begins
integrating. The readout of the rows also follow the
same routine. The waveforms depicting the CFRS out-
put data stream refer to

3.1.1 CFRS Video Encoded Data stream
The
55), on page 62
pixel data stream in Continuous Frame Rolling Shutter
mode is encoded/formatted. In default mode, internally
generated signals SOF, VCLK, HCLK etc. drive the in-
tegration and readout of the pixel data frames but only
the valid pixel data is readout of the sensor. When a “1”
is written to bit 5 of the
Register, (Table 55), on page
pixel data to be encoded with SOF, VCLK and End Of
Frame signals. It accomplishes this by attaching the pix-
el data with certain predefined signal data. The
Encoded Signal Definitions, (Table 2), on page 10
fines the data that represents the SOF, VCLK and End
of Frame signals.
