Information detection processing system

Abstract

Abstract PURPOSE: To obtain an objective information which can be collated easily, by detecting a background information and the objective information superposed on this background information, and separating this detected information, from said back ground information processing the objective information only. CONSTITUTION: When a form 2 is carried in the direction as indicated with an arrow, a data of the line which has been vertically irradiated by the light source 3 is read by the image sensor 4. At the same time, the data is read by the image sensor 6 through the filter 5 for cutting off a red light beam only. When the data which has been read by the sensor 6 in made binary, it becomes a character 1 of a black background, and a red mark part and a white part of the form become "0". On the other hand, when the data which has been read by the sensor 4 is made binary, the background and the mark part become "1" and the form part becomes "0". Therefore, when the data of the sensor 6 is subtracted from the data of the sensor 4 by the video processing part 7, only the data of a red mark part is obtained. When only the part where a mark exists, as to this data is output by the impression detection part 8 and is input to the transmission part 9, the facsimile 10 of the receiving side is able to obtain a record of the impression.
