Abstract: Halftoning is performed on a source image. The halftoning includes error diffusion processing of one separation based on error diffusion processing of another separation. The error diffusion processing includes determining a rendered pixel value for the one separation by applying a quantization function for a given pixel. The quantization function is based on both a modified input determined as a function of an error value of a pre-rendered pixel for the one separation and an error value determined as a function of rendered pixel values for the another separation. A rendered image is output, which includes the same plural color separations. The output rendered image is populated with, for the one separation, a rendered pixel value based on the application of the quantization function.

Abstract: Apparatus are provided, which include a color image processor, an edge distinguisher, and an edge trapping mechanism. The color image processor processes color images, including a given color image. The given color image includes plural color separations each having a set of color values for respective image pixels. The edge distinguisher distinguishes some edges of the given color image as opposing edges. An edge is a transition in the color separation of the given color image from a non-white color intensity value, at one side of the edge, to a white intensity value, at the other side of the edge. A given edge is an opposing edge when a transition of the given edge goes, for a separation of the given color image, in one direction from a non-white color value to a white value, and goes, for another separation of the given color image, in the same direction from a white value to a non-white color value.

Abstract: Transmission of messages composed on one or more input devices to a single or multiple recipients by means of one or plural communication modes is facilitated. Such communication modes may include conventional or wireless telephone, facsimile transmission, pager, e-mail, postal mail or courier. Thus, a message may be directed to a single recipient via multiple modes, such as e-mail and fax, in order to ensure the earliest possible receipt of the message; or may be directed to multiple recipients by a single mode or by different modes. In the case of multiple-mode delivery, “escalation” rules may specify conditions under which different delivery modes may be sequentially employed. Automatic follow-up to determine whether a message has been received, as well as automatic sender notification upon confirmation of receipt, may be employed. The system is capable of sending messages having embedded questions, and facilitating multi-question surveys.

An access code request input requests, via the computer screen user interface, an access code for use by the authorized information seeker to access the remote database via the internet protocol connection. An access code output outputs the access code for use by the authorized information seeker.

The input-output value converter includes a number of stored conversion parameter sets corresponding to respective different positions in the cross-process direction of the pixel data. The number of stored conversion parameter sets is a fraction of the total number of pixel positions in the cross-process direction of the pixel data.
