Title: Portable medium
Inventor: IIJIMA YASUO
IPC: B42D15/02
Filed: 1985-10-28
Abstract: PURPOSE:To improve the data transmitting accuracy and also to increase the data processing speed by processing data on an integrated circuit IC card with respect to the instruction data given from an external device and inhibiting the processing for another instruction data in case it is received for a period during which the answer data is delivered in the form of the result of card data processing. CONSTITUTION:When a transaction using an IC card 1 is received, the transaction data is analyzed to select a desired function and to decide a sequence. The first instruction data is sent to a reading CPU and a CPU 11 of an IC card handler is kept under a waiting state until the answer data showing the end of the processing to the instruction data is returned from the reading CPU. In such a way, collision is avoided on a transmission line between the answer data given from the card 1 and the instruction data given from an IC card reading/writing part 20. Thus improves the data transmitting reliability as an IC card system.

Filed: 1984-11-16
Abstract: PURPOSE:To give a fresher image with a little skewness by installing a means to select one of plural filter output signals based upon the distance from a border of the block, reducing a block skewness and restoring a high area component. CONSTITUTION:A register 1 rearranges a decoding signal converted and coded for respective blocks, gives to the first and second low area passing filters 2 and 3 and the first and second high area emphasizing filters 4 and 5 and a clock signal is supplied to shift the data. An average type filter frequency characteristics cut a high area component of the input signal. On the other hand, the frequency characteristics of the differential type filter like the filters 4 and 5 emphasize the high area component of the input signal. Thus, in the decoding image signal at the area round the block border, a discontinuous level change is smoothed by the action of the filters 2 and 3, the high area of the decoding image signal at the area away from the block border is emphasized by an action of the filters 4 and 5 and thereby, the after treated decoding image signal can be obtained from a selecting circuit 6.
