摘要： An image input section enters a document image including a bar code, and converts the document image into a binary image. An image memory section memorizes the binary image supplied from the image input section. A mask judging section performs a scanning operation using an M.times.M pixel window for detecting an alternate pattern from the binary image supplied from the image input section. A small pattern removing section removes small patterns from a binary image sent from the mask judging section. An expanding section expands a pattern involved in a binary image by an amount equivalent to k1 pixels when this binary image is sent from the small pattern removing section. A contracting section contracts a pattern involved in a binary image by an amount equivalent to k2 pixels when this binary image is sent from the expanding section. A region detecting section obtains the feature quantity of each pattern involved in a binary image sent from the contracting section, and detects a bar code candidate region based on the detected feature quantity. And, a decoding section decodes a detected bar code by reading a specific image region from the image memory section when the specific image region corresponds to the bar code candidate region detected by the region detecting section.

摘要： An image input section enters a document image including a bar code, and converts the document image into a binary image. A small pattern removing section removes small patterns from a binary image sent from the input section. A labeling section separates the binary image into labeled regions and calculates the feature quantity including a center position of each labeled region. A region detecting section makes a group of labeled regions spaced at a predetermined positional relationship based on their feature quantities and detects a bar code candidate region. A decoding section decodes the bar code based on the feature quantity involved in the bar code candidate region.

摘要： Pieces of feature information in a bi-level image such as a width, a branching point and an ending point of a wiring pattern are detected in a design rule checking section according to a micro inspection to find out pieces of feature information departing from a design rule. Also, feature codes in the bi-level image such as a corner of the wiring pattern are detected in a specific shape detecting section according to a macro inspection. The feature information are compared with pieces of referential feature information pertaining to a non-defective wiring pattern in a first comparing and judging section to judge whether the wiring pattern indicated by the feature information is defective or non-defective. The feature codes are compared with referential feature codes pertaining to a non-defective wiring pattern in a second comparing and judging section to judge whether the wiring pattern indicated by the feature codes is defective or non-defective. Therefore, defective types and portions of the wiring pattern can be detected by performing the macro inspection and the micro inspection in parallel without dividing the wiring pattern into processed regions.
摘要翻译：根据微观检查，在设计规则检查部中检测诸如布线图案的宽度，分支点和终点的双层图像中的特征信息的部分，以从设计中发现特征信息规则。此外，根据宏观检查，在特定形状检测部中检测诸如布线图案的角部的双电平图像中的特征码。将特征信息与第一比较判断部中与无缺陷布线图案有关的参考特征信息进行比较，以判断由特征信息指示的布线图案是否有缺陷或无缺陷。将特征代码与第二比较判断部分中与无缺陷布线图案有关的参考特征码进行比较，以判断由特征码指示的布线图案是否有缺陷或无缺陷。因此，通过并行地进行宏观检查和微观检查，可以检测不良类型和布线图案的部分，而不将布线图案划分为加工区域。

摘要： It is an object of the present invention to receive/play a streaming immediately after a switching not to disconnect it when a terminal for receiving the streaming is switched from a first receiving terminal to a second receiving terminalA communication method of switching a receiving terminal of a streaming to which a rate control using TFRC is applied from a first receiving terminal to a second receiving terminal, includes a deciding step of deciding whether or not a route on a network between a transmitting terminal of the streaming and the first receiving terminal is identical to a route on the network between the transmitting terminal and the second receiving terminal, and a transferring step of transferring history information of a packet loss that the first receiving terminal is managing to the second receiving terminal when it is decided that both routes are identical.

摘要： A router includes a multicast packet transmitting unit that multicasts the identifier of the router periodically, a relay determining unit that determines whether a received data packet should be relayed to a router in another segment, an order determining unit that determines, on the basis of information included in multicast packets from the other routers, the router to which the data packet shall be transferred, and a packet relaying unit that, when the data packet is not relayed, notifies the transmission source which transmitted the packet as to the router selected by the order determining unit to be the relay destination and then transfers the data packet to the selected router. A router suitable for relaying the packet is thus selected. Since switching of the relay router may be performed by following the router redirection message, it is unnecessary to add a new function to a terminal.

摘要： Between network connection apparatuses connected to each other by use of a virtual redundant arrangement, a first network connection apparatus that is in a standby state receives an advertisement message from a second network connection apparatus that is active as a network connection apparatus, and uses a priority comparing section to compare its own priority with the priority in the received advertisement message. When its own priority is higher, the first network connection apparatus uses a master down timer comparing section to compare the remaining time of a master down timer with the time as weighted in accordance with its own priority and resets the timer for a shorter time.

摘要： A packet routing method for quickly reorganizing a path from a transmission source terminal to a destination terminal. A radio receiver part (103) detects, from a decrease of the field intensity or the like, a cut-off of a communication with a communication device using a radio signal to directly transmit packets. A control part (105) determines whether the local terminal device including it is the packet destination radio terminal device or the packet transmission source radio terminal device. When it is determined that the communication with a communication device using the radio signal to directly transmit packets is cut off and that the local terminal device is the transmission source radio terminal device, a radio transmitter part (104) broadcasts a request signal of path restoration addressed to the packet destination communication device.

摘要： A packet routing apparatus that simultaneously implements prompt route recovery and continuation of communication by an optimal route. A radio reception section (103) receives a radio signal including packet data received in a transmission/reception antenna (101) via a circulator (102). Further, the radio reception section (103) detects disconnection of an adhoc network by a decrease in electric filed strength of a signal from a communicating party. A radio reception section (104) transmits a radio signal including a route search packet, route response packet or the like from the transmission/reception antenna (101) via the circulator (102). When the adhoc network is disconnected, a control section (105) performs processing of route recovery for transmitting a route search packet to a destination wireless adhoc terminal, while performing route reconstruction processing for reporting route disconnection to a transmission source wireless adhoc terminal.
