PURPOSE:To facilitate initial setting based on the visual observation of attributes by operating the result of the judgment based on the visual observation of the pattern of a standard sample and the parameter of the pattern of the standard sample, and computing the threshold value of the parameter for judging the attributes. CONSTITUTION:The pattern of a standard sample for setting a threshold value for an image recording and regenerating device 1 is sequentially outputted and displayed on a CRT monitor 2. The attributes of the pattern are judged visually. The result of the judgment is inputted into a data processing control device 4 and stored in the device 1. The sample data of the standard sample are sequentially read into the device 4 through an image receiving device 3. At the same time, the result of the visual judgment stored in the device 1 is read through an interface circuit 10. The device 4 computes the parameters for judging the attributes for the read standard sample. Said procedure is repeated for all the standard samples. The computed parameters and the results of the visual judgment are compared and operated 4, and the threshold value of the parameters is computed. Said value is stored in the device 4 as the initialized value and used for the actual judgment of a body to be detected. |
