0003 Renesas R-Car Fine Display Processor (FDP1) Driver
0004 ==================================================
0005
0006 The R-Car FDP1 driver implements driver-specific controls as follows.
0007
0008 ``V4L2_CID_DEINTERLACING_MODE (menu)``
0009 The video deinterlacing mode (such as Bob, Weave, ...). The R-Car FDP1
0010 driver implements the following modes.

0017 * - ``"Progressive" (0)``
0018 - The input image video stream is progressive (not interlaced). No
0019 deinterlacing is performed. Apart from (optional) format and encoding
0020 conversion output frames are identical to the input frames.
0021 * - ``"Adaptive 2D/3D" (1)``
0022 - Motion adaptive version of 2D and 3D deinterlacing. Use 3D deinterlacing
0023 in the presence of fast motion and 2D deinterlacing with diagonal
0024 interpolation otherwise.
0025 * - ``"Fixed 2D" (2)``
0026 - The current field is scaled vertically by averaging adjacent lines to
0027 recover missing lines. This method is also known as blending or Line
0028 Averaging (LAV).
0029 * - ``"Fixed 3D" (3)``
0030 - The previous and next fields are averaged to recover lines missing from
0031 the current field. This method is also known as Field Averaging (FAV).
0032 * - ``"Previous field" (4)``
0033 - The current field is weaved with the previous field, i.e. the previous
0034 field is used to fill missing lines from the current field. This method
0035 is also known as weave deinterlacing.
0036 * - ``"Next field" (5)``
0037 - The current field is weaved with the next field, i.e. the next field is
0038 used to fill missing lines from the current field. This method is also
0039 known as weave deinterlacing.
