deinterlace

deinterlace ( integer Input, integer Output [, integer Field =0 ] )

Use this function to remove motion artifacts from an image acquired with an interlaced video device. The function removes odd or even lines from the image and substitutes them with the interpolated lines.

Parameters

Input

An integer between 0 and 116 specifying the input image frame number. A value of 0 represents the DMA memory buffer of the video device. Values in the range of 100-116 correspond to hidden frames.

Output

An integer between 1 and 116 specifying the output image frame number. Values in the range of 100-116 correspond to hidden frames.

Field

An enumerated integer that describes the field used for interpolation. Must be one of the following values:

F_ODD=0 – leaves odd lines intact and interpolates even lines

F_EVEN=1 – leaves even lines intact and interpolates odd lines

Default value: F_ODD

Error flags

ERR_OK

The flag set if successful.

ERR_FAILED

The flag set if failed.
