Abstract:
A method to determine the color status of a scanned original segments a binary halftone image into a predetermined number of local windows and converts each local window to a device-independent color space. The method then determines a color space parameter for each local window and compares the color space parameters for the local windows to at least one threshold to determine the color status of the scanned original. An apparatus having a scanner creates a scanned image of an original and has at least one processor to create a binary halftone image from the scanned image, segment the binary halftone image into a predetermined number of local windows, convert each local window to a device-independent color space, determine a color space parameter for each local window, and compare the color space parameter for each local window to at least one threshold to determine the color status for the scanned original.
