3. IS OFF series is converted to the size of a postcard by a viewing distance of 65 80cm The image stabilization performance in f stops 2 is located by the intersection points of the IS ON and IS OFF curve with the determination limit of 63um 1 The numerical value of the IS Performance is displayed in f stops IS Performance 2 2 4 RESULT DATA SELECTION To select single results of the IS Performance calculation just move one of the sliders 1 for SERIES EXPOSURE TIME PICTURE or ROI region of interest This changes the displayed results for the edge spread function ESF 3 spatial frequency response SFR 4 and the INPUT IMAGE 5 tab Detailed Information can hide and show by the INFO button 6 Data selection Image Engineering STEVE 6D 9 Q BS copyrichtinronmation 2 2 5 EDGE SPREAD FUNCTION ESF Every edge width is calculated by the ESF Therefor an oversampled slanted edge of an image ROI is calculated out of every image Every image includes twenty of them Ten in pitch and ten in yaw direction Some other important information s are the overshoot and undershoot This vales are indicators for image processing done by the camera signal processor 2 2 6 SPATIAL FREQUENCY RESPONSE SFR The SFH is not used for IS Performance calculation It describes the modulation transfer function of every ROI 2 2 7 INPUT IMAGE AND ROI SELECTION It is possible to change
