There is set forth herein an imaging terminal operative for decoding of bar codes. In one embodiment the terminal can include a color imaging assembly having a color image sensor array. The terminal can be operative for capture of a color frame of image data. Responsively to the capture of the color frame of image data the terminal can convert the color image data to monochrome image data while maintaining the color image data. The terminal can utilize the monochrome image data to search for a color bar code finder pattern. The terminal can be operative so that if the color bar code pattern is found utilizing the monochrome image data the terminal can utilize the color image data for attempting to decode a color bar code.
