An apparatus, method and computer-readable storage medium are provided for processing images, such as medical images, in accordance with an imaging calibration function during execution of an image viewing application, and also for processing other types of images with a different calibration function during execution of a different application. In regards to an apparatus, the apparatus is caused to identify, in conjunction with an image viewing application, an imaging calibration function. The apparatus is also caused to transform a digital image during execution of the image viewing application in accordance with the imaging calibration function and to output the digital image, following transformation, in accordance with the image viewing application. In conjunction with a different application, the apparatus is caused to identify a second calibration function, different than the imaging calibration function, and to cause output of a digital image following transformation in accordance with the second calibration function.
