A region information processing system processes information concerning a plurality of objective regions in a field to produce information concerning a synthetic region to be formed by synthesizing the information concerning the objective regions. The information concerning each of the objective regions is provided by external region information source. The region information processing system comprising: A subfield designating device sequentially designates subfields each constituting part of the field, by providing, one at a time, subfield designating data. A plurality of surveying devices are each associated with a corresponding one of the regions and are each responsive to the subfield designating data for examining the region information source to produce local data of the subfield being designated concerning the associated region, the local data including at least region flag data indicating whether or not the subfield is inside the boundary of the associated region. A synthensizing device is responsive to the local data of the subfield concerning the objective regions for judging whether or not the local data of the subfield concerning the objective regions satisfy a predetermined condition to produce, depending on the result of the judgement, region flag data indicating whether or not the subfield being designated is inside the synthetic region.

There is disclosed a data processing apparatus in which when a data existence position pulse indicative of the input of a data signal is supplied, a process of the supplied data signal is started in response to the leading edge of the data existence position pulse, a pulse signal of a predetermined width is generated after the elapse of only a first predetermined time from the leading edge of the data existence position pulse, the generation of an output data signal indicative of the result of the process is blocked by a switch for the generating period of the pulse signal, and the output data signal indicative of the result of the process is relayed and transmitted by the switch for only a second predetermined time from the extinguishment of the pulse signal. Thus, only the effective data can be generated.
An information memory control system include: a memory unit having a memory medium for storing a plurality of information in the form of a plurality of data blocks each of which contains an information data and an attribute data of the information data; an access unit for accessing the memory unit so as to read out each of the data blocks from the memory medium; a selection unit directly coupled to the memory unit for distributing each of the read-out data blocks to a plurality of output ports of the selection unit according to the attribute data; a processing unit coupled to one of the output ports of the selection unit as so to correspond to the attribute data for processing the information data according to the attribute data; and an output device coupled to the processing unit for outputting the processed information data. A plurality of processing units can be respectively coupled to the plurality of output ports of the selection unit, and a plurality of output devices can be respectively coupled to the plurality of processing units.
A minicomputer provides signals representative of an image to three memory units via a sixteen bit data bus. Signals representative of sixteen central pixels of the image and neighbors thereof are provided from the memory units to a tessellation memory. In response to the central pixels and their neighbors forming a predetermined pattern, signals representative of the central pixels may be altered, whereby the central pixels are processed simultaneously. Signals representative of the processed central pixels are provided to the minicomputer via the data bus.
An image synthesization method, whereby a plurality of images, each of which has a partially overlapping image area, are synthesized to create a single synthetic image, comprises a determination step of inputting a plurality of image data sets that correspond to the plurality of images that are input, and of determining whether or not an image in the partially overlapping image area of each of images that are indicated by the plurality of image data sets includes mainly characters an image processing step of performing, for the plurality of image data sets that are input, image processing in consonance with a result of a determination performed at the determination step and an image synthesization step of synthesizing images that are indicated by the resultant plurality of image data, for which the image processing has been performed at the image processing step. With this arrangement, a plurality of images can be easily and effectively synthesized.
