Abstract: An image processing system which can learn user's preference to satisfy him to the full, and also comprises means for inquiring a user about his satisfication degree to enhance it. The image processing system comprises means for learning user's preference such as his manner of setting and pressing a button, a destination, a condition set for copying, and means for changing a control parameter on the basis of the learning result.

Abstract: A facsimile apparatus has a transparent plate on which a document may be located. The document is then scanned by a scanner which includes electronic solid state light generation means e.g. LEDs which illuminate the document, with the light reflected from the document being detected by a detector. An electronic signal corresponding to an image of the document may then be transmitted to a remote location. Alternately, the facsimile apparatus may be used to copy the document. Cut paper sheets are withdrawn from storage and an image printed thereon by a heat transfer system in which a film of ink is selectively heated. Paper on which an image has been printed is then received on the upper surface of the storage. The facsimile apparatus may also have a document transporter for moving a document past the scanner with the scanner fixed.

Abstract: An optical recording sheet includes a plurality of data columns consisting of optical recording dots arranged in a matrix shape and column markers corresponding to the data columns. The data columns and the column markers of the optical recording sheet are detected by an optical line sensor and stored in a memory. On the basis of information stored in the memory, a marker detector detects the column marker and then two memory coordinates having a position known relative to the column marker are calculated. From the two memory coordinates, an inclining angle detector calculates the inclining angle between the optical recording sheet and the optical line sensor. On the basis of the memory coordinates and the inclining angle, an address calculator restores the optical recording dots stored in the memory coordinates.

Abstract: On the transmitting side of a facsimile system, a predictive picture signal x.sub.ij of a pel (i, j) is obtained, taking account of predictive picture signals of pels prior to the pel (i, j), which have been previously obtained. A two-level transposition signal d.sub.ij is determined in accordance with the predetermined on the basis of an actual picture signal x.sub.ij, the predictive picture signal x.sub.ij and a dither threshold t.sub.ij. The thus obtained transposition signal d.sub.ij is encoded by use of the MH or MR coding method and transmitted to a receiving side of the facsimile system. Compared with the conventional case, in which a dither signal z.sub.ij itself is encoded and transmitted, the transposition signal d.sub.ij can be considerably compressed, when it is encoded for transmission by use of the MH or MR coding method.

Abstract: A recording apparatus comprising an input terminal to which a picture information signal to be recorded is applied, a driver for moving an electrostatic printing medium in a predetermined direction, an apparatus for electrifying the electrostatic printing medium, a thermal printing head for heating the electrostatic printing medium in accordance with the picture information signal to reduce the resistance of the heated regions of the electrostatic printing medium, thereby forming a pattern of resistance-reduced region on the electrostatic printing medium, so that a charge pattern (electrostatic latent image) according to the picture information signal is formed on the surface of the electrostatic printing medium.
