RGB to Grayscale Conversion
Color images often have to be converted to grayscale, providing input data for subsequent digital image
processing like edge detection filters, OCR etc. The RGB-to-grayscale conversion performs a reduction of
the RGB color data into a single channel luminance image.
Figure 117 shows an example of RGB-to-gray conversion. The image on the left represents the original
RGB color image. The output grayscale image on the right is the result of the conversion process.

RGB-to-Gray Conversion in the CameraSuite SDK
In the
CameraSuite SDK
the
ImageProcAPI
provides the programming interface for executing the
RGB-to-gray conversion. The bit depths and image types supported are shown in Table 63. For a detailed
description on how to use this feature please refer to the
CameraSuite API Help
located in the doc folder of
the
CameraSuite SDK
installation directory.
