摘要： An image forming apparatus which forms a halftone image on a print medium by using a multipass process to scan a printhead N (N is an integer of 2 or more) times in a single area on the print medium and form dots by each scan operation includes a pass division unit which sets the print density of a scan operation in the first pass so as to prevent dots from overlapping with each other on the print medium, and sets the print densities of scan operations in the second to Nth passes, a tone reduction unit which generates print data of the respective scan operations in accordance with the print densities set by the pass division unit, and a printhead which prints a halftone image on a print medium on the basis of the print data generated by the tone reduction unit.

摘要： This invention encodes an image mixed of a character or line-drawing image and a natural image. An extraction unit extracts the color of a pixel, which constitutes a high-frequency component, from the input image data as an extracted color and generates identification information indicating whether each pixel in the image data is a pixel of an extracted color or non-extracted color. A replacement unit replaces a pixel value of an extracted color with an average value of non-extracted colors. Using a window having a size of 2×2 pixels, a reducing unit generates one pixel from the window after replacement. If even one non-extracted-color pixel exists in the window, the average value of non-extracted colors within the window is determined to be a pixel value of the reduced image. A packing unit concatenates the extracted color, the result of lossless-encoded identification information and lossy-encoded data of the reduced image.

摘要： Even an image in which a gradation character/line image having variations in pixel values to a certain degree and a natural image are mixed can be reproduced with sufficient quality in the gradation character/line image and high encoding efficiency, and further, encoded data can be generated with high encoding efficiency. An extraction unit binarizes pixel values in an input block with a predetermined threshold, thereby generates identification information identifying pixels to be substituted and pixels not to be substituted. An average differential value generation unit calculates a differential value between an average value of the pixels to be substituted and an average value of the pixels not to be substituted. A substitute color generation unit subtracts the differential value from the pixels to be substituted. An encoding unit encodes the identification information, the differential value and pixel values of the block after substitution.

摘要： The colors used for forming an image are limited in advance to a predetermined number of color patterns called representative colors; on the host side the image data received is divided into blocks, for each of which a representative color is determined in a representative color code conversion unit; the representative colors and their associated representative color codes are transmitted to the printer side; and on the printer side the representative color codes are converted into dot patterns in a pattern conversion unit for each pass before being output. The above procedure allows a series of processing—resolution conversion, masking/UCR processing, output γ correction and binarization processing—to be realized with a simple configuration.

摘要： When recording a gradation pixel by performing pseudo-halftone processing, the occurrence of unevenness in the density in the recorded image is suppressed. For that purpose, when recording a pseudo-halftone image using dot patterns, a dot-pattern table storing a plurality of different dot patterns is provided for each gradation value. One dot-pattern table is selected from N dot-pattern tables based on gradation-value information for each pixel. One dot pattern is selected from the selected dot-pattern table, based on position information indicated by the pixel, and recording is performed using the selected dot pattern. It is thereby possible to prevent the concentrated use of a particular nozzle of a recording head, and suppress the occurrence of unevenness in the density due to characteristics of the specific nozzle.

摘要： An apparatus is provided which is capable of directly and efficiently measuring surface contamination of objects to be measured having curved surfaces such as inner and outer surfaces of pipes without the need for cutting pipes, etc. This radioactivity measuring apparatus comprises a radioactivity detection section 10 and a radioactivity measuring section 12 arranged separately and connected together via cables 14. The radioactivity detection section has a structure in which a plurality of elongated plate-shaped radioactivity detection units 16 are arranged in the width direction and connected together in a detachable manner using connecting fittings 18. Each of the connecting fittings is formed in such a way that it is bent at angles between surfaces of parts thereof on which the respective radioactivity detection units are mounted corresponding to the shape of the surface to be measured. Using the connecting fittings having different angles between mounting surfaces allows flat surfaces or even curved surfaces with arbitrary curvatures to be measured in conformity with the shape of the surface.

摘要： In a system to which a plurality of devices are connected, each device has heretofore required a connector for an AC adapter and a connector for a signal line. Further, in order to arrange it so that the amount of power supplied to the overall system will not exceed a limit value, it has been required to adjust the amount of power during system use by turning the power source of each device on or off. According to the present invention, a signal line for data transfer and a power line for supply of power in a system connecting a plurality of devices are consolidated in a single cable to make it possible to connect both lines to one connector of each device. The power controller of a certain device acquires the properties of a plurality of devices connected to this device, decides the optimum power distribution and controls the power controllers of each of the other devices.
