QSVGA
A QSVGA mode is available for applications where higher
resolution image capture is not required. Only half of the pixel
rate is required when programmed in same frame rate with sub-
sampling method. If you keep the same pixel rate with skip
method, the maximum frame rate is 120. Default resolution is
400 x 300 pixels and can be programmed for other resolutions.
Refer to Table 11. QSVGA Digital Output Format (YUV
beginning of line) and Table 12. RGB Data Format for further
information.
QCIF
A QCIF mode is available for further resolution decrease. Two
method used to get this mode, sub-sampling and skip. The first
one can get better quality than the second one and the second
approach can have higher frame rate. The maximum frame rate
is 240 for QCIF. The default resolution is 200 x 150.
Video Output
The video output port of the OV8610/OV8110 image sensors
provides a number of output format/standard options to suit
many different application requirements. Table 6, Digital Output
Format indicates the output formats available. These formats
are user-programmable through the SCCB interface.
YUV Output
The OV8610/OV8110 supports ITU-656 and ITU-601 output
formats, providing VSYNC, HREF, and PCLK as standard
output video timing signals.
ITU-601/ITU-656
The OV8610/OV8110 imager supports both ITU-601 and ITU-
656 output formats in the following configurations (See Table 7.
4:2:2 16-bit Format and Figure 6. Pixel Data Bus (YUV Output)
for further details):
- 16-bit, 4:2:2 format
(This mode complies with the 60/50 Hz ITU-601 timing
standard. See Table 7. 4:2:2 16-bit Format)
- 8-bit data mode
(In this mode, video information is output in Cb Y Cr Y
order using the Y port only and running at twice the
pixel rate during which the UV port is inactive. See
Table 8. 4:2:2 8-bit Format).
The OV8610/OV8110 imager provides VSYNC, HREF,
PCLK, FODD, and CHSYNC as standard video timing
signals.
In ITU-656 modes, the OV8610/OV8110 imager asserts SAV
(Start of Active Video) and EAV (End of Active Video) to
indicate the beginning and the ending of the HREF window. As
a result, SAV and EAV change with the active pixel window.
The OV8610/OV8110 imager offers flexibility in YUV output
format. The device may be programmed to standard YUV 4:2:2.
The device may also be configured to “swap” the UV sequence.
When swapped, the UV channel output sequence in the 16-bit
configuration becomes:
- V U V U···.
The 8-bit configuration becomes:
- V Y U Y···.
The third format available in the 8-bit configuration is the Y/UV
sequence swap:
Y U Y V···.
RGB Raw Data Output
The OV8610/OV8110 imager can also be programmed to
provide 8-bit RGB raw data output. The output sequence is
matched to the OV8610 color filter pattern.
The video output appears in Y channel only and the UV
channel is disabled in 8-bit RGB raw data. The output
sequence is B G R G.
B/W Output
The single-chip camera can be configured for use as a black
and white image device. The vertical resolution is higher than in
color mode. Video data output is provided at the Y port and the
UV port is tri-stated. The data (Y/RGB) rate is equivalent to 16-
bit in color mode.
The MSB and LSB of Y/UV or RGB output can be reversed. Y7
is MSB and Y0 is LSB in the default setting. Y7 becomes LSB
and Y0 becomes MSB in the reverse order configuration. Y2-
Y6 is also reversed appropriately.
