Rgb To Grayscale Conversion - Smartek UCC User Manual

8.2.10 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.
