Title
Image Quality Of Digital Cameras
Abstract
Linear systems theory is routinely used to determine the behavior of imaging systems. The effect of smear, aberration, detector size, etc. can be characterized by a modulation transfer function (MTF). The individual MTFs can be multiplied together to compute the system MTF.In sampled systems, as seen in CCD cameras, quantifying the MTF is not as easy. The effects of the aliasing and relative phase error require a new method of computing the MTF using statistical procedures.The new MTF estimation method employs a simple edge target to sample the digital array. The edge measurements can then be converted to an average MTF using Second Moment statistics. This new image quality measure(1) is easily extended to predict the performance of color CCD cameras. In addition, the Second Moment can be used to predict the image quality of the displayed image when it's viewed at different magnifications.
