1.8 Digital Output Format Table
Note: “Y” in the table means this combination is supported by OV7620.
1. RGB CCIR656 format means 4-byte SAV and EAV is inserted at the beginning and ending of
HREF, which are used to grab Vsync and Hsync information. So only use 8-bit data bus line and
don’t need
VSYNC
and
CHSYNC
signal line.
2. Y/UV swap is valid only in 8 bit output. Y channel output sequence is Y U Y V ... rather U Y V
Y ....
3. To YUV format, U/V swap means UV channel output sequence swap. V U V U ... rather U V
U V ... for 16 bit; V Y U Y ... rather U Y V Y ... for 8-bit.
4. To RGB format, U/V swap means neighbor row B R output sequence swap. So refer to preview
RGB raw data output format, different format change accordingly.
5. MSB/LSB swap means: Default Y/UV channel output port relationship is:
