摘要： An image detection system is disclosed for the detection of an image in an input pixel stream. An image is input as a input pixel stream (19) and accumulated and converted (112,113,114) into cells which are formed into cell data portions from regions of a corresponding image of the input pixel stream (19). A template storage ROM (15) stores at least one template that comprises a multiplicity of cell data entries derived from an desired image to be detected. A comparator matrix (115) is connected to the cell converter (112,113,114) and the template ROM (15) for comparing the cell data portions with a multiplicity of cell data entries to derive a template detection signal (215) when a predetermined number of the cell data portions match with the multiplicity of said cell data entries. The system finds particular use in the prevention of fraudulent copying of images, such as bank noted using colour laser copiers and printers.

摘要： A character-detecting section detects characters from an image that has been read from a document. In order to allow a character-recognizing section to make a judgement as to whether or not the character is identical to any character of specific documents, such as paper money and securities, stored in a RAM, a discrimination-level setting section generates discrimination patterns corresponding to the discrimination level, and supplies them to the character-recognizing section. As a result of the judgement based on the discrimination at a low level, if the document is judged as one of the specific documents, a specific-document judging section controls the discrimination-level setting section in order to allow the character-recognizing section to make a re-judgement for identification. Thus, the discrimination-level setting section supplies discrimination patterns at a higher level to the character-recognizing section. This arrangement makes it possible to shorten the processing time that is required for discrimination as to whether or not the document in question is any of the specific documents, as well as making it possible to ensure the reliability of discrimination.

摘要： When a predetermined pattern (e.g. a pattern indicating the serial number of a copying machine) is added on an image formed on a recording paper, the image formation apparatus according to the invention suppresses fog appeared by addition of the predetermined pattern in the vicinity of the image. More particularly, a control circuit which inputs and processes an image signal estimates the leading and ending edge position of the recording paper with respect to the transferring direction and the edge which is perpendicular to the transferring direction of the recording paper based on the signal obtained from an ITOP generation circuit and BD detector. Accordingly, an effective area for image formation on the recording paper is obtained and the modulation amount for adding the predetermined pattern is controlled in accordance with the position on the recording paper to which the predetermined pattern is outputted.
