Abstract:
A method for calibrating and characterizing an image capture device, comprising the steps of:i) calibrating a display device to generate a calibrated display; ii) displaying at least one reference image on the calibrated display to generate a calibrated reference image with known calorimetric properties, said at least one reference image simulating the average correlated color temperature of a light source of images to be subsequently captured; iii) capturing at least one image from an image capture device to be calibrated, to generate a captured image; iv) comparing the captured image with the known calorimetric properties of the calibrated reference image; v) computing a relationship between the captured image and the known calorimetric properties of calibrated reference image; and vi) writing a profile describing colorimetric characteristics of the image capture device according to the relationship such that the profile can be used to calibrate the image capture device.
