Luminance Calibration and Linearity Correction Method of Imaging Luminance Measurement Devices

This paper presents that the opto-electrical characteristic of a typical CCD based digital camera is nonlinear. It means electric signal camera's detector - not linear function luminance value on lens. The feature needs to be transformed into if this used as distribution measurement device known Imaging Luminance Measurement Device (ILMD). article methodology for obtaining and focuses non- linearity correction method.
