摘要： A method for selecting a halftoning mode to be applied to regions within an image. The method operates on received image data to identify low-level regions within the received image data. The low-level regions are defined and separated by edges. Pixels that are not separated by edges are considered to belong to the same region. After the regions have been identified, low-level image attributes for the image data within each region are compiled. A halftoning method suited for the image data within the region can be selected based upon low-level image attributes.

摘要： PROBLEM TO BE SOLVED: To provide an image processing apparatus and method, and a program, for printing to output image data subjected to pseudo halftone processing with proper density characteristics.
SOLUTION: The image processing apparatus generates a pseudo halftone image from a multivalue image using a dither threshold array, and generates a difference image between each of one or more pseudo halftone images each having density characteristics different from those of the generated pseudo halftone image and the generated pseudo halftone image. There are stored the generated pseudo halftone image and the generated one or more difference image. Density characteristics for printing a pseudo halftone image from the multivalue image are determined. When it is determined that printing is performed with density characteristics different from those of the stored pseudo halftone image, by combining the stored difference image in response to the determined density characteristics and the stored pseudo halftone image, a pseudo halftone image is generated and output in order to print the combined and generated pseudo halftone image.

摘要： The present invention relates to providing a designer with the tools for the manipulation of differential gloss in halftoned images. A special mask layer is provided for the rendering of desired glossmark image data. The desired glossmark image data is used to select between two halftones with anisotropic structure characteristics which are significantly different in orientation while remaining identical in density. This selection is made for each corresponding portion of primary image data. In this way, a halftone image of the primary image is generated with glossmarks imbedded therein which will display differential gloss without the need for special toners or paper.

摘要： An image processing device of the invention processes images with threshold matrices in either of two available print modes, that is, a first print mode and a second print mode. When a combination of the printing resolutions of the second print mode in the main scanning direction and in the sub-scanning direction is identical with an interchanged combination of the printing resolutions of the first print mode in the main scanning direction and in the sub-scanning direction, a threshold matrix for the first print mode is rotated by 90 degrees to set a threshold matrix for the second print mode. When the printing resolutions of the second print mode in the main scanning direction and in the sub-scanning direction are respectively n times (where n denotes a positive number) of the printing resolutions of the first print mode in the main scanning direction and in the sub-scanning direction, on the other hand, a threshold matrix for the second print mode is used as a threshold matrix for the first print mode. This arrangement desirably saves the memory capacity for storage of the threshold matrices.

摘要： PROBLEM TO BE SOLVED: To suppress image quality deterioration for character images or the like while suppressing a necessary memory capacity to a low capacity by performing an image processing on image information in which the resolution of input image information is decreased to a low resolution. SOLUTION: A band drawing processing part 205 analyzes input information, draws the image of RGB data of a pixel unit corresponding to an image to be printed, also analyzes the input information and generates the RGB data of the fine pixels of the low resolution (600[dpi]) and the shape information (DOT information) of the fine pixels of a high resolution (1200[dpi]). Then, low resolution images are converted to the output images of the high resolution (1200[dpi]) from the RGB data stored in a main memory, the DOT information, and the RGB data of the fine pixels.

摘要： PROBLEM TO BE SOLVED: To suppress graininess degradation depending on the low frequency components of images and to form the images of high image quality by performing N-ary processing (N is an integer ≥2) based on predetermined constraint information for every main scanning. SOLUTION: When performing printing of a plurality of paths by a recording head provided with a plurality of nozzles, a scan duty of each nozzle is calculated for every scan of the recording head in a scan duty setting part 105 corresponding to input image data. In a halftone processing part 10, the N-ary processing based on the predetermined constraint information is applied to the calculated scan duty and a dot pattern to be a formation object is prepared. The constraint information is set so that the phase of the spatial frequency of the dot pattern prepared next to the already recorded dot pattern becomes an opposite phase in a low frequency zone.
