A medical support system enables one server bidirectionally connected to one terminal to bidirectionally communicate with another server bidirectionally connected to another terminal. Each of the one server and the other server comprises: a conference processing unit configured to perform a conference between the one terminal and the other terminal; an image sharing processing unit configured to bidirectionally share an image between the one server and the other server; and a control unit configured to control the entire server over a network, wherein the control unit of the one server transmits only operation information sent from the one terminal to the control unit of the other server, and the control unit of the other server controls based on the received operation information.

A non-aqueous electrolyte secondary battery comprises at least a negative electrode, a positive electrode and a non-aqueous electrolyte. The negative electrode has an active material comprised of silicon or a silicon alloy containing lithium represented by composition formula Li.sub.x Si where x satisfies 0.ltoreq..times..ltoreq.5. The positive electrode has an active material comprised of a transition metal oxide. The non-aqueous electrolyte is a lithium ion-conductive non-aqueous electrolyte having at least one lithium compound comprised of one of an organic solvent and a solid polymer. The negative electrode active material is formed by absorption of lithium ions into the silicon resulting from an electrochemical reaction between the negative electrode and a lithium metal and/or a material containing lithium. A secondary battery having high voltage, high energy density, high reliability, improved current charge and discharge characteristics and a long cycle life is obtained.

A method of detecting a particular area of a document where an image to be processed exists, and applicable to an image forming apparatus. Image information representative of an image printed on a document and position information representative of a marked area of the image data are detected. The image information lying in the marked area is extracted, erased, inverted as to black and white or otherwise processed on the basis of the detected image information and position information and without a mark being directly written on the document.

Method of detecting a processing area of a document for an image forming

An image processing apparatus has a function of enlarging or reducing an image which is processed by a certain magnification. A modulation transfer function (MTF) correction circuit is provided in the image processing apparatus and the correction quantity or filter characteristic of this MTF correction circuit is automatically changed depending on a change in the magnification.

Image processing apparatus

An image processing system processes an input image data related to a dot image which is obtained by scanning a document in a scanning direction. The image processing system smoothens a density of a dot image based on a predetermined smoothing matrix and successively outputs smoothened picture element data which constitute an image data, delays the smoothened picture element data by a predetermined time in the scanning direction, successively averages two picture element data having a mutual time difference equal to the predetermined time and outputs average values, and subjects the average values to a pseudo halftone process.

Image processing system and method

An image processing system includes a density magnification processing unit for taking an average in density of two adjacent image data only at a point of change in the main scanning direction in a size enlargement mode. Thus, the density variation in the main scanning direction is made smoother.

Image processing system having a selective magnification function

An image processing method and system in which an original image is read line by line by means of a plurality of image sensors to produce image data segments corresponding to respective segments of a line read by each of the image sensors. The image data segments produced by the image sensors are processed to produce a second plurality of image data segments, which are subsequently subjected to a predetermined image processing operation. The second plurality of image data segments are combined, either before or after being subjected to image processing, into a line of image data for each original image line. The optical processing performed on the second plurality of image segments is typically magnification or minification, and is performed by storing the second plurality of image segments in a memory and controlling the clock and the address of the memory by means of selective magnification data stored in another memory, wherein the magnification data are selected in accordance with the desired magnification or minification.

In an electrophotographic copier, while a document is transported toward a predetermined position on a glass platen, its lateral dislocation and skew with respect to a document transport path as well as an amount of the dislocation and a direction of the skew are commonly sensed by a single sensor. The single sensor is positioned adjacent to one of laterally opposite ends of the transport path and has sensing surface of a predetermined area. While the document moves past the sensing surface of the sensor, the sensor generates a signal which corresponds to an area of the sensing surface which is occupied by the sheet.
