摘要： A run length which is the length of a run representing continuous black pixels is calculated on the basis of binary image data, and an extending process is performed for the run using a target pixel as an object to generate an extended run. An extended run length representing the length of the extended run and a maximum run length representing the length of the longest run in the range of the extended run are calculated. If a difference between the extended run length and the maximum run length is smaller than a predetermined value, an image near the target pixel is determined as a character image. If the difference is equal to or larger than the predetermined value, the image is determined as a half-tone image. In this manner, accuracy in separation between the half-tone area and the character area in a document image can be improved.

摘要： Even if a calculation result is out of range (e.g., below 0 or over 255 in the case of an 8-bit color signal) of a destination color signal when a color conversion table is generated by matrix calculation, clipping (non-reversible operation) is not performed, and a constant is evenly added to the matrix calculation result irrespectively of whether the value range is exceeded or not, to fit the calculation result in a predetermined data type and store as a table value. Further, subtraction of the added constant is defined as an operation immediately after table interpolation, to obtain a final correct color conversion output.

摘要： An image producing section produces a character or pattern image indicative of the input conditions of a color scanner section. The input conditions include data on the resolution, the sampling rate, etc. An image synthesis section synthesizes the produced image with an image scanned by the color scanner section and subjected to predetermined image processing. The resultant synthesized image is printed out by a color printer section. The operating conditions, such as the image input conditions, are clear from the character or pattern image printed out as part of the synthesized image.
