    摘要: To realize a coordinate reading apparatus which is capable of easily setting a particular function to a switch provided on a coordinate indicator, and an interface unit and a coordinate reading system for the coordinate reading apparatus. A coordinate detecting section 21 detects a coordinate value for a position indicated by a coordinate indicator 3 and a switch status. A function selecting means 22 determines that a menu provided on a tablet 2 is read from the coordinate value and the status, to store functional data assigned to the menu in a memory means 23. A conversion status determining means 24 determines that the inputted status coincide with the status to be converted stored in the memory means 23, to notify coincidence to a conversion status output means 25. Receiving the notification, the conversion status output means 25 outputs data to be outputted stored in the memory means 23 instead of inputted switch status.

    摘要: A color correction device which minimizes color differences throughout an area to be subjected to color reproduction includes a dynamic range conversion circuit for the colors cyan, magenta, and yellow, a separation circuit for separating the colors into high order bits and low order bits, and a CMY table reference for obtaining CMY table values corresponding to the high order bits. An interpolation circuit performs an interpolation process based on the low order bits and the CMY table values. A K-table reference obtains four K-table values corresponding to black, and a CMY correction circuit corrects for the values of cyan, magenta, and yellow based on three interpolated data from the interpolation circuit and three data obtained by the K-table reference.

    摘要: To suppress color moire in a color image recording apparatus, a method for recording a color image by forming record dots of at least first through third colors on a recording medium in a plurality of lines of record dots each extending in a main scan direction and a plurality of rows of record dots each extending in a sub-scan direction, includes the step of forming the record dots of first through third colors with a different disposition pattern effective to avoid the occurrence of color moire. In a preferred embodiment, the disposition pattern of the record dots of one of the three colors comprises an ordinary zigzag printing pattern in which selected ones of the record dots in each line of record dots are shifted in the sub-scan direction by a uniform amount, the disposition pattern of the record dots of another one of the three colors comprises a modified ordinary zigzag pattern in which a dot pitch between lines of record dots in the sub-scan direction is a non-integer multiple of the dot pitch of the ordinary zigzag printing pattern, and the disposition pattern of the remaining one of the three colors comprises a modified ordinary zigzag pattern in which corresponding record dots in adjacent lines of record dots are closer to each other than are the record dots in adjacent rows.
