Abstract: PROBLEM TO BE SOLVED: To realize halftone processing to a large volume of image data at high speed and still record high-quality images by carrying out the halftone processing in two stages of an error diffusion method by a computer and a dither method by a printer. SOLUTION: At a computer 90, a plurality of dots are formed for each pixel in accordance with an image data of a first resolution having a gradient value for each pixel, thereby expressing a halftone. A color printer 22 prints images with a second resolution higher than the first resolution. At this time, the image data is input as a third-resolution data in a smaller range than the second resolution and multi-valued to a predetermined gradient value through an error diffusion for each pixel constituting the image data, whereby a second image data is generated. A resolution of the second image data is converted to the second resolution, whereby a third image data is generated. A fourth image data is generated from the third image data to form images.

Abstract: PURPOSE:To detect a parity error by line classification by adding an identification code for its own terminal station equipment an opposite terminal station equipment to the head of a frame of a transmission data and checking the parity corresponding to the opposite terminal station equipment as to the multiplex reception data. CONSTITUTION:An identification code adding means 11 sets the identification code of its own station and a transmission destination terminal equipment in pairs corresponding to the repetition of each block to the head block of the frame. A time division branching device 20 receives a transmission data from each terminal equipment synchronously with the frame. For example, when a transmission data from the terminal equipments A, B to the terminal equipment C exists, the transmission data is sent to the terminal equipment C by the time division multiplex transmission format. A parity checking means in the terminal equipment C checks the parity of the multiplex reception data continuously. When any parity error is detected by the parity check, since the code of the transmission destination terminal equipment is also received, the line causing a parity error is specified.
