摘要： A white background determination section performs a white background determination on the basis of a white threshold calculated by a white threshold calculation section and an area size selected by an area size determination section. A character discrimination section executes character recognition such that a condition for character discrimination is relaxed when the white background determination section determines that a pixel of interest belongs to a white background, and the condition for character discrimination is made stricter in other cases.

摘要： An ink amount correction system is provided in a color image printer system for printing a full color image by mixing yellow, magenta, cyanogen and India ink amount signals. The ink amount correction system includes: a plurality of color ink amount correction circuits which include a quantization section for quantizing a color ink amount indicative signal representative of the amount of an ink of a predetermined color corresponding to each of picture elements of a primary color image; an error calculating section for calculating a quantization error between the input and output of the quantization section, to output as a quantization error signal; and a feedback correction section for adding the quantization error signal derived by the error calculating section, to the corresponding color ink amount indicative signal of the surrounding picture element, for correcting the ink amount indicative signal. The average value of the quantization error signal is added before the quantization of an ink amount indicative signal of a black ink having the maximum influence upon luminance. As a result, it is possible to reduce the dispersion of the degree of overlapping of inks for each of the picture elements to carry out the recording of good quality, in a case where a color image is printed by means of inks of a plurality of colors using error diffusion.

摘要： An input section performs a color conversion process, etc. for image data from a color scanner section. A discrimination section generates a discrimination signal representative of “character”, “non-character”, etc. on the basis of an image signal from the input section. A first processing section performs a filtering process, etc. for the image signal from the input section, and switches the method of such a process on the basis of the discrimination signal from the discrimination section. An enlargement/reduction section enlarges or reduces the discrimination signal from the discrimination section and the image signal from the first processing section. A second processing section subjects the enlarged/reduced image signal form the enlargement/reduction section to a black-added printing process, a gamma conversion process, etc., and switches the method of such a process on the basis of the enlarged/reduced discrimination signal from the enlargement/reduction section.

摘要： The main CPU executes Fourier transform to the partial image, then performs strict spectrum analysis 1 for judging the presence/absence of data at a coordinate position designated in advance on a Fourier transform plane with high resolution for judging the presence/absence of prohibition of duplication, then judges whether duplication-prohibited data exists or not, and clears both the partial image and the document image if it is judged that duplication-prohibited data exists. If it is judged that duplication-prohibited data does not exist, the main CPU executes spectrum analysis 2 for broadly inspecting the existence of a periodic component instead of lowering the resolution from the spectrum analysis 1 and judges whether a structure other than DC component exists or not. If the existence of a minute quantity of change that could not exist in a normal image is recognized, the main CPU performs partial image processing such as amplifying the quantity of change, then superimposes it onto the document image, and supplies the image on which the superimposing processing has been executed, to an output unit and a liquid crystal display unit, thus outputting or displaying the image.

摘要： In an image processing apparatus, a pre-process section 101 eliminates a characteristic in original image data, which is possibly confused with a characteristic of a digital watermark, before the digital watermark is embedded. A watermark adding section 102 adds the digital watermark to still image data that is pre-processed by the pre-process section. A watermark extraction section 103 extracts the digital watermark. Thereby, a frequency component, which corresponds to a region of a frequency component to be embedded, is eliminated in advance, and the added digital watermark alone can be extracted.
