Abstract:
1. A failure analysis system comprising: an obtaining portion that obtains read-in image information that is image information obtained by reading an output image; a memory that stores fundamental image reduction information that is information in which an information amount of fundamental image information is reduced, the fundamental image information serving as a fundamental of the output image; a calculating portion that calculates a characteristic value of a projecting waveform by use of differential information between read-in image reduction information and the fundamental image reduction information, the read-in image reduction information being information in which the information amount of the read-in image information obtained by the obtaining portion is reduced, the fundamental image reduction information being stored in the memory; and a determining portion that determines a defect type group that is a group of defect types of elements included in the output image by use of a clustering process on the basis of the characteristic value calculated by the calculating portion, wherein: the memory further stores output image reduction information that is information in which the information amount of the image information serving as a fundamental of the output image output in the past is reduced; the fundamental image reduction information is the output image reduction information stored in the memory; the read-in image reduction information is the image information expressing the read-in image information with a smaller color number than that of the read-in image information; the fundamental image reduction information is the image information expressing the fundamental image information with a smaller color number than that of the fundamental image information; and the output image reduction information is the image information expressing the output image information with a smaller color number than that of the output image information.
