Abstract: The tone reproduction curve is smoothed to eliminate or reduce artifacts due to abrupt changes in the final system tone reproduction curve. As the tone reproduction curve approaches an end point, it is modified, if necessary, so that the angle between a tangent to the tone reproduction curve at a point, and a line from that point to the end point is less than a threshold value. The end point is considered to be a corner of a box, the threshold value is a function of the distance from the point to the nearest of the walls of the corner, and the threshold value goes to zero as the distance to the wall goes to zero. Thus, the tone reproduction curve is guided to the end point in a smooth and monotonic fashion.

Abstract: In a digital scanner or other source for sending documents by electronic mail to a client, the size of the document is determined and a calculation is made of how many segments the document must be divided into. If the required number of segments is so large as to present a risk of flooding a network, a warning is displayed to a user. The system is particularly useful in the context of scanning to e-mail full-color images.

Abstract: Systems and methods for detecting image quality defects in images rendered by a rendering device. Original image data is rendered by an image rendering device, and the rendered image is captured by an image capturing device. Regions of interest may be identified to provide information indicating where image quality defects of the rendering device, may be identified. At each region of interest, the original image data may be compared to the captured image data of a corresponding region of interest to determine color difference of the captured image at the region of interest. The color difference may be subsequently converted from a device independent color space to a device dependent color space. Based on the converted color difference and input intensity of the original image data at the region of interest, a colorant error may be determined for the region of interest, and/or a scan line and a row line including the region of interest.

Abstract: A data analyzer stores data values at any one of N stages while associating the data values with a plurality of data elements respectively and stores association weighting information among the data elements, selects one of the data elements as a target data at random and computes an input stimulus value concerned with the target data on the basis of the association weighting information between the target data and the other data elements and the data values of the other data elements, and updates the data value of the target data on the basis of the computed input stimulus value in such a manner that a threshold decided in accordance with a current data value associated with the target data and varying according to each data value is compared with the input stimulus value to determine whether the data value needs to be changed or not, and that the data value is updated when a decision is made that the data value needs to be changed.

Abstract: A user conducts a telephone conversation without speaking. It does this by moving the participant in the public situation to a quiet mode of communication (e.g., keyboard, buttons, touchscreen). All the other participants are allowed to continue using their usual audible technology (e.g., telephones) over the existing telecommunications infrastructure. The quiet user interface transforms the user's silent input selections into equivalent audible signals that may be directly transmitted to the other parties in the conversation.
