The *saturation* (s) and the *value* (v) are measured in percentage of the cylinder: 0 being the smallest value and 255 the maximum. The values are packed in 24 or 32 bit formats. .. raw:: latex \begingroup \tiny \setlength{\tabcolsep}{2pt} .. tabularcolumns:: |p{2.6cm}|p{0.8cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}|p{0.22cm}| .. _packed-hsv-formats: .. flat-table:: Packed HSV Image Formats :header-rows: 2 :stub-columns: 0 * - Identifier - Code - - :cspan:`7` Byte 0 in memory - :cspan:`7` Byte 1 - :cspan:`7` Byte 2 - :cspan:`7` Byte 3 * - - - Bit - 7 - 6 - 5 - 4 - 3 - 2 - 1 - 0 - 7 - 6 - 5 - 4 - 3 - 2 - 1 - 0 - 7 - 6 - 5 - 4 - 3 - 2 - 1 - 0 - 7 - 6 - 5 - 4 - 3 - 2 - 1 - 0 * .. _V4L2-PIX-FMT-HSV32: - ``V4L2_PIX_FMT_HSV32`` - 'HSV4' - - - - - - - - - - h\ :sub:`7` - h\ :sub:`6` - h\ :sub:`5` - h\ :sub:`4` - h\ :sub:`3` - h\ :sub:`2` - h\ :sub:`1` - h\ :sub:`0` - s\ :sub:`7` - s\ :sub:`6` - s\ :sub:`5` - s\ :sub:`4` - s\ :sub:`3` - s\ :sub:`2` - s\ :sub:`1` - s\ :sub:`0` - v\ :sub:`7` - v\ :sub:`6` - v\ :sub:`5` - v\ :sub:`4` - v\ :sub:`3` - v\ :sub:`2` - v\ :sub:`1` - v\ :sub:`0` * .. _V4L2-PIX-FMT-HSV24: - ``V4L2_PIX_FMT_HSV24`` - 'HSV3' - - h\ :sub:`7` - h\ :sub:`6` - h\ :sub:`5` - h\ :sub:`4` - h\ :sub:`3` - h\ :sub:`2` - h\ :sub:`1` - h\ :sub:`0` - s\ :sub:`7` - s\ :sub:`6` - s\ :sub:`5` - s\ :sub:`4` - s\ :sub:`3` - s\ :sub:`2` - s\ :sub:`1` - s\ :sub:`0` - v\ :sub:`7` - v\ :sub:`6` - v\ :sub:`5` - v\ :sub:`4` - v\ :sub:`3` - v\ :sub:`2` - v\ :sub:`1` - v\ :sub:`0` - .. raw:: latex \endgroup Bit 7 is the most significant bit.
