Claim One:
1. A method for measuring performance parameters of an infrared focal plane array module performed by an infrared imaging camera unit and a computer, wherein the infrared imaging camera unit has an infrared focal plane array (IRFPA) module and is connected to the computer, the IRFPA module serves to detect a black body radiation source, and the computer serves to perform image division and analysis of performance parameters on images acquired by the infrared imaging camera unit, the method comprising steps of: capturing continuous digital images from the IRFPA module; performing image division on each of the continuous digital images to generate multiple divided digital images with each divided digital image corresponding to a response area of the continuous digital image; and measuring multiple performance parameters of each divided digital image, wherein the multiple performance parameters are classified into types of a signal transmission function (SiTF), a temporal noise equivalent temperature difference, a spatial noise equivalent temperature difference, non-uniformity and operability and are calculated by using a responsivity function.
