K-6 Color Filter
No filter is applied to image. If you are attempting to read symbols with no filter applied, a white balance
should be performed first to balance the red, blue, and green cells of the image sensor.
This is a general purpose filter that is applied to the RGB image to provide a grayscale image that can
be used for most applications.
This filter should be used when reading 2D symbols, 1D symbols that are not positioned horizontally in
the field of view, or a combination of 1D and 2D symbols.
This filter is applied to the RGB image to provide a grayscale image that is specifically designed to
provide the best suitable image for a horizontally-positioned 1D symbol.
This filter should be used when reading 1D symbols that are positioned horizontally across the field of
view.
This filter is applied to the RGB image to provide a grayscale image for decoding similar to a luminance
calculation. Unlike a luminance calculation, Green Interpolate provides an image 1:1 resolution to the
input image. This filter provides better omni-directional symbol decode performance. Like Horizontal 1D
Symbols, and unlike General Purpose, a white balance is not necessary.
This filter is recommended for most decoding applications that can afford extra processing time.
•Note: For high-resolution 1D symbols that are positioned horizontally, the Horizontal 1D Symbols filter is preferable.
Definition: If you are using a 5 megapixel color MicroHAWK V430-F-series, this filter
captures an image in color. To process the image for symbol decoding,
the image must be filtered or the R, G, and B cells need to be equalized.
This can be done by applying one of the filters available or by perform-
ing a white balance with the current camera configuration before trying to
decode a symbol. This option specifies the filter method that is applied to
the RGB color image to produce a monochrome image.
