摘要： PURPOSE:To shorten the graphic process time by avoiding the mixture of the code showing the unnecessary neutral tints in case the binary graphic, for example, is encoded. CONSTITUTION:In case the color graphic, for example, is encoded as the multi- value graphic, the graphic is divided into R, G and B components with n-bit applied to each component. When the graphic of P-bit smaller than n-bit such as the binary white/black graphic is encoded under these conditions, all of R, G and B components have a change in the color component. In this connection, the quantizing bit of each component is coincided with the highest-rank bit when the highest-rank bits of all components have some change. Otherwise, a bit conversion is given so that all color component bits are coincided with the highest-rank bit Q2 of G component for instance. As a result, the conventional same encoding system can be applied even though the input graphic is binary or multi-value. Furthermore, the undesired code of neutral tints, for example, can be prevented from being mixed into the code of the binary graphic.

摘要： PURPOSE:To make easy the recognition of a fixed region by removing temporarily the signal which displays the fixed region from the display signal for the entire figure and then, by adding a display signal which puts emphasis so that an operator can recognize the region. CONSTITUTION:In the graphic display equipment which displays a figure on its display unit, a signal in an interval indicated by fixed-region position signal S2 is removed from display signal S1 displaying the figure by inverter 2 and AND circuit 3, and display signal S3 is outputted. Then, rise detection circuit 4 detects the rise of region position signal S2, its output and the fixed discrete value of counter 5 supplied with clocks are OR-ed by OR circuit 6, and its result is applied to FF7. Next, outputs of FF7, and outputs of change-over circuit 12 supplied with horizontal driving pulse HD and vertical driving pulse VD are, and region position signal S2 are AND-ed respectively by AND circuits 8 and 9 so as to region display signals S4 and S5, so that either display signal S6 or S7 will be outputted via OR circuits 10 and 11.

摘要： PROBLEM TO BE SOLVED: To provide a card information transmission method and system device where restriction on time required for retrieval of card information is avoided so as to increase the number of contained terminals and to be able to response immediately to a request from other terminals and the terminal processing is made efficient. SOLUTION: In the transmission of information relating to a card between a terminal 1 and a server 3, after each terminal 1 sends card information, a line between the terminal 1 and the server 3 is interrupted, and retrieval is requested to an external server 5. The server 3 receives retrieval information M8 from the external server 5. After the arrival to a transmission enable state to the terminal 1, the server 3 makes setup to the terminal 1 to connect the line again and sends a setup message M10 with the retrieval information M8 added thereto.

摘要： PROBLEM TO BE SOLVED: To provide an electronic seal system and an approval method allowed to utilize computer cards, which are capable of preventing stealing, modification, copying, erasing, etc., of seal impression data and history data of a seal impression data user, and which enable a receiver of a digital document to check the seal impressions of all persons in charge from a preparer of the digital document up to the user himself (or herself), and also to check the validity of the digital document at each approval. SOLUTION: This system is provided with a user's terminal equip 1, an approver's terminal equipment 2 and a processor's terminal equipment 3 which are connected to an open network. A user imprints a digital document with a preparer/user seal by using a user's computer card 1c, an approver imprints the digital document with an approver's seal for user approval by using an approver computer card 2c and finally processor approves the approver/user of the digital document by using a processor computer card 3c. Thus the digital document is approved and the relative processing is executed.
