Abstract:
1. An image processing apparatus for determining whether or not a chromatic color is included within image data having a predetermined number of pixels in each of a first direction and a second direction orthogonal to the first direction, said apparatus comprising: first determination means for temporarily determining for each pixel string in the first direction that the pixel string is a chromatic pixel string, when a frequency of appearance of pixels determined to be chromatic according to a predetermined condition consecutively by a first number is larger than a second number; second determination means for determining a frequency of appearance of the pixel string temporarily determined by said first determination means consecutively by a third number, wherein at least one of the first number and the second number, and the third number have different values; and third determination means for determining whether or not a chromatic color is included in the image data, based on a result of determination by said first determination means and a result of determination by said second determination means.
