Every four consecutive colour components are packed into 5 bytes. Each of the first 4 bytes contain the 8 high order bits of the pixels, and the fifth byte contains the two least significants bits of each pixel, in the same order.</para> <para>Each n-pixel row contains n/2 green samples and n/2 blue or red samples, with alternating green-red and green-blue rows. They are conventionally described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example of one of these formats:</para> <example> <title><constant>V4L2_PIX_FMT_SBGGR10P</constant> 4 × 4 pixel image</title> <formalpara> <title>Byte Order.</title> <para>Each cell is one byte. <informaltable frame="topbot" colsep="1" rowsep="1"> <tgroup cols="5" align="center"> <colspec align="left" colwidth="2*" /> <tbody valign="top"> <row> <entry>start + 0:</entry> <entry>B<subscript>00high</subscript></entry> <entry>G<subscript>01high</subscript></entry> <entry>B<subscript>02high</subscript></entry> <entry>G<subscript>03high</subscript></entry> <entry>B<subscript>00low</subscript>(bits 7--6) G<subscript>01low</subscript>(bits 5--4) B<subscript>02low</subscript>(bits 3--2) G<subscript>03low</subscript>(bits 1--0) </entry> </row> <row> <entry>start + 5:</entry> <entry>G<subscript>10high</subscript></entry> <entry>R<subscript>11high</subscript></entry> <entry>G<subscript>12high</subscript></entry> <entry>R<subscript>13high</subscript></entry> <entry>G<subscript>10low</subscript>(bits 7--6) R<subscript>11low</subscript>(bits 5--4) G<subscript>12low</subscript>(bits 3--2) R<subscript>13low</subscript>(bits 1--0) </entry> </row> <row> <entry>start + 10:</entry> <entry>B<subscript>20high</subscript></entry> <entry>G<subscript>21high</subscript></entry> <entry>B<subscript>22high</subscript></entry> <entry>G<subscript>23high</subscript></entry> <entry>B<subscript>20low</subscript>(bits 7--6) G<subscript>21low</subscript>(bits 5--4) B<subscript>22low</subscript>(bits 3--2) G<subscript>23low</subscript>(bits 1--0) </entry> </row> <row> <entry>start + 15:</entry> <entry>G<subscript>30high</subscript></entry> <entry>R<subscript>31high</subscript></entry> <entry>G<subscript>32high</subscript></entry> <entry>R<subscript>33high</subscript></entry> <entry>G<subscript>30low</subscript>(bits 7--6) R<subscript>31low</subscript>(bits 5--4) G<subscript>32low</subscript>(bits 3--2) R<subscript>33low</subscript>(bits 1--0) </entry> </row> </tbody> </tgroup> </informaltable> </para> </formalpara> </example> </refsect1> </refentry>
