摘要： An image processor performs a high accuracy orientation determination process on a color image. A color component analyzer determines a frequency of appearance of each color component based on color image data of an input original document, and an orientation determining block determines the orientation of the original document by a character recognition process based on the frequency of appearance result. The color image data is then subjected to a predetermined editing in accordance with the determination results, and the edited image data is output.

摘要： An image processing apparatus includes an image input device for photoelectrically converting a document image which has been optically read and for inputting the converted document image as image data. An area separator separates a plurality of areas included in the input image data from one another and a character recognition is performed from a plurality of directions with respect to character data in the image data input by the image input device with reference to a character recognition dictionary. The apparatus performs a first discriminating function of discriminating, for the plurality of areas separated by the area separator, respective reliabilities in a plurality of directions on the basis of results of the character recognition, and second discrimination function for discriminating a document direction on the basis of average values of the reliabilities discriminated by the first discriminating function.

摘要： A color image transmitting method for transmitting a color image composed of a color image portion and a binary image portion is disclosed. Data about the color image portion and data about the binary portion are separated from each other by the positional data so as properly to be compressed or encoded respectively. The data about the color image portion, data about the binary image portion and positional data about one or both of the two image portions are successively transmitted so that the color image can efficiently be transmitted.

摘要： A server is connected to an Ethernet port via a network and is further connected to a copier via video interface ports. The server is capable of subjecting image data read in by the copier or obtained from the network to processing for character recognition, coding and translation by a character recognition circuit, image coding/decoding circuit and translating circuit. Furthermore, image data is capable of being generated by a page-description-language interpreter based upon data, which is in the format of page description language, received from the network. Conversely, a character in the image data is capable of being recognized, coded and converted into page description language so that the amount of data sent to the network can be reduced.

摘要： An image block is detected by raster scanning an input image and chasing surrounding black pixels around a detected black pixel as the start point in sequence. Further, by judging the feature of the detected image block, the attribute of the image block can be judged. Also, by comparing the detected image block with a predetermined window, it is possible to determine whether or not the image block is noise, whereby image processing of higher accuracy can be effected.

摘要： Document image data entered from a scanner are separated into a plurality of areas by an area separation unit. Attributes are assigned to respective ones of the plurality of partial areas obtained in the area separation unit. For instance, a character area in the main body of text and a character area in a table are examples of area attributes. Each of these attributes is assigned a degree of priority in advance. A character recognition/orientation discrimination unit detects character orientation in each of the plurality of partial areas and discriminates document orientation. The orientation of the document image data is determined based upon the document orientation of each partial area discriminated by the character recognition/orientation discrimination unit and the degree of priority of the attribute assigned to each partial area. Further, first and second recognition units for recognizing characters used in the Japanese and English languages, respectively, are provided, and the image data undergo recognition by each of these recognition units. The recognition rate of each result of recognition is obtained, the recognition rates are judged by a decision unit and one of the results is selected by a selector based upon the judgment made. The selected result of recognition is outputted.
