5. API for Acquiring/Changing Parameters of VN-E4 _
5.3. JPEG Encoding
Setting Interpolation for VN-E4
Format
/api/param?encode(Number).interpolate=Data
Example
When setting interpolation of Encoding No. 1
/api/param?encode(1).interpolate=on
Example of response
encode(1).interpolate&200 OK
Interpretation
Change interpolation of the specified encoding number. Note that encoding numbers are different from video
input channels. When this is set to on, JPEG-compression will be performed upon creating VGA based on the
first field out of the 2 fields that make up the video frame. When this is set to off, the video frame will be
directly JPEG-compressed. Images with intense motion will not appear blurred when this is set to on. For
images with little motion, set to off to obtain a high resolution image. This setting is valid when the frame size
is in VGA (Encoding Nos.: 1, 3, 5 and 7). When the frame size is in QVGA (Encoding Nos.: 2, 4, 6 and 8), this
will be invalid as only the first field will be used from the beginning.
