| Renesas R-Car Fine Display Processor (FDP1) Driver |
| ================================================== |
| |
| The R-Car FDP1 driver implements driver-specific controls as follows. |
| |
| ``V4L2_CID_DEINTERLACING_MODE (menu)`` |
| The video deinterlacing mode (such as Bob, Weave, ...). The R-Car FDP1 |
| driver implements the following modes. |
| |
| .. flat-table:: |
| :header-rows: 0 |
| :stub-columns: 0 |
| :widths: 1 4 |
| |
| * - ``"Progressive" (0)`` |
| - The input image video stream is progressive (not interlaced). No |
| deinterlacing is performed. Apart from (optional) format and encoding |
| conversion output frames are identical to the input frames. |
| * - ``"Adaptive 2D/3D" (1)`` |
| - Motion adaptive version of 2D and 3D deinterlacing. Use 3D deinterlacing |
| in the presence of fast motion and 2D deinterlacing with diagonal |
| interpolation otherwise. |
| * - ``"Fixed 2D" (2)`` |
| - The current field is scaled vertically by averaging adjacent lines to |
| recover missing lines. This method is also known as blending or Line |
| Averaging (LAV). |
| * - ``"Fixed 3D" (3)`` |
| - The previous and next fields are averaged to recover lines missing from |
| the current field. This method is also known as Field Averaging (FAV). |
| * - ``"Previous field" (4)`` |
| - The current field is weaved with the previous field, i.e. the previous |
| field is used to fill missing lines from the current field. This method |
| is also known as weave deinterlacing. |
| * - ``"Next field" (5)`` |
| - The current field is weaved with the next field, i.e. the next field is |
| used to fill missing lines from the current field. This method is also |
| known as weave deinterlacing. |
