    摘要: Partial images each constituting a predetermined matrix are sequentially taken out, and density data corresponding to pixels constituting the matrix are subjected to correction. The correction of the density data is so made as to respectively add density correcting values predetermined to correspond to pixel positions in the matrix to the density data. Consequently, the density data corresponding to the pixels constituting the matrix are considerably varied. Therefore, in a binary image obtained by subjecting the partial image constituting the matrix to halftone processing, the density of a document image is sufficiently reproduced.

    摘要: A data managing device according to the present invention processes the same object pixel before and after variable magnification processing, and collectively manages processing data before and after the variable magnification processing by making access to a memory once. In the variable magnification processing before and after which the number of object pixels differs, 1-bit BF data for area separation processing performed before the variable magnification processing and 7-bit produced error data for error diffusion processing performed after the variable magnification processing are mixed, and data composed of a total of 8 bits which is obtained by the mixing is read out/written from and to the same address in a SRAM 4 at the same access timing. Therefore, at the time of reduction processing, a reduction processing control signal SMWAIT is produced, and error diffusion processing is stopped when the signal is at a high level.

    摘要: The present invention provides a half-tone image processing method utilizing an error diffusion technique which allows for the density adjustment of a half-tone image to be reproduced. When the density of an object pixel is converted into binary-coded data, a binary-coding object value is first calculated by adding a density value of the object pixel to an error sum of binary-coding errors distributed to the object pixel from peripheral pixels around the object pixel. Then, the binary-coding object value is compared with a threshold value TH for judging whether the object pixel is a black pixel or a white pixel. The binary-coding object value is also compared with a reference value GSLVB or GSLVW which can be variably set for the calculation of a binary-coding error HG of the object pixel. The level of the binary-coding error HG can be adjusted by variably setting the reference values GSLVB and GSLVW. Thus, the density adjustment of a half-tone image can be realized.

    摘要: An image data processing apparatus for performing processing using data corresponding to a plurality of lines which correspond to a plurality of scanning lines at the time of reading an image. For example, when processing is performed using data corresponding to three lines, that is, the present line, a line one ahead of the present line and a line two lines ahead of the present line, a line memory having a capacity of two lines is used. When the data corresponding to the line two lines ahead of the present line are read out from the memory, the data corresponding to the present line are written to storage locations from which the data have been read out. Consequently, it is possible to perform processing using data corresponding to three lines using a line memory having a capacity for two lines.
