method and device for generating rahmenfehlerdiffusion and tintenmengenbegrenzung by schwellewertmatrix

摘要

The present invention relates to a process for the establishment of a frame (1) of signals representative of an image, by diffusion of error, a representation of the pixels in the "vector " of a space (2) of representation, at least one dimension of which corresponds to a chromatic component and in which certain vectors, referred to as" reference " vectors, each correspond to a composition that is printable or chromatic directly displayed by the device to which the frame is intended, characterized in that it comprises at least one step of limitation of ink by the use of at least one matrix (3) of the threshold values containing the threshold values calculated from at least a portion of the signals representative of the coordinates (x11, y11) of the pixel (11) in the image. An embodiment consists in that the matrix (3) is generated by a circuit (300).
