Abstract
PURPOSE:To make the display of hot patterns free from variance possible by averaging plural times of calibration output differences based on one piece out of plural IR ray detecting elements storing the same in a memory and correcting the outputs of the detecting elements. CONSTITUTION:An IR ray detecting element DET 1 or the like out of the plural elements DET1- disposed for the purpose of measuring temp. distributions is selected as a reference at calibration, and the detection output of the element DET1 is digitally converted and is stored in a register R1. Thence, this stored value and the digital detection outputs of the respective elements DRT2- are successively compared in an operational amplifier OP, and the differential values are written respectively in memories M1-. This is repeated, and the correction values for the detection output by the variances of the elements DET2- based on the element DET1 are stored in the memories M1- by the addition and the division by the repeated times, after which these are written respectively in PROMPR1-. The outputs of the elements DET2- at the measurement are added and corrected according to the contents of the PROMPR1-, whereby the heat patterns free from variances are displayed.
