摘要： The invention provides a method of burying additional information in an image, which can suppress deterioration of image quality and reduce an extraction error rate when extracting the additional information. For implementing the method, in an image processing apparatus for burying predetermined information in a color image, the apparatus comprises an input unit for inputting a color image; a quantizing unit for quantizing the input color image with an error diffusion process for each of predetermined color components; and a quantizing condition control unit for controlling, in accordance with the predetermined information, periodicity at which an amplitude of a quantizing threshold is modulated by the quantizing unit. The quantizing condition control unit controls a phase in the amplitude modulation of the quantizing threshold to be different between at least one of the color components and the other color components.

摘要： This invention provides an image processing apparatus which can effectively remove conspicuous noise contained in image data, while suppressing deterioration of image information. Image data containing noise is input from an input terminal (100). Based on the output condition upon outputting image data after noise is removed, a parameter determination module (103) determines predetermined parameters used in a noise removal process. An example of the output condition is information associated with a resolution upon outputting image data. An individual noise removal module (104) removes noise contained in the image data using the parameters, and image data after the noise has been removed is output from an output terminal (105).

摘要： A surrounding pixel reference unit reads out and stores image data having a predetermined size from a line buffer. A color judgment unit detects the color of the image (reference image) stored in the surrounding pixel reference unit. A parameter determination unit determines parameters used in an individual noise removal unit on the basis of the color detected by the color judgment unit, and supplies them to the individual noise removal unit. The individual noise removal unit reads out, from the line buffer, an image which is located at the same position as that read out by the surrounding pixel reference unit and has a size according to the parameters supplied from the parameter determination unit, and executes a noise removal process for the readout image in accordance with the parameters supplied from the parameter determination unit.

摘要： An image processing apparatus, an image processing method, and a computer program, visually remove low-frequency noise contained in image data. Image data containing low-frequency noise is input from an input terminal. A window unit designates a window made up of a pixel of interest, and its surrounding pixels. A pixel selector selects a selected pixel to be compared with the pixel of interest from the window, and a pixel value determination unit determines a new pixel value of the pixel of interest on the basis of the pixel values of the selected pixel and pixel of interest. New image data is generated by substituting the pixel value of the pixel of interest by the new pixel value.

摘要： Upon embedding additional information in image information, since an image region in which the additional information can be embedded is limited, the information size that can be embedded is often limited, and all pieces of additional information cannot be embedded. Before the additional information is embedded in the image information, distribution information of pixel values is obtained by scanning the image information, and the information size that can be embedded is detected and displayed on the basis of the obtained distribution information of pixel values.
