Abstract: The present disclosure relates to color calibration chart acquisition. In an example, a video acquired by an imaging device may be processed. The video may be analyzed to automatically detect a reproduction of a color calibration chart. Upon detection of a reproduction of the color calibration chart, it may be determined whether color calibration chart reproduction quality is within a selected quality threshold. Upon determining that color calibration chart reproduction quality is not within a selected threshold, user feedback may be provided, via the imaging device, to dynamically guide the user to make adjustments in the video acquisition in order to obtain a color calibration chart reproduction within the selected quality threshold.

Abstract: In the present disclosure techniques related to display of device independent color differences are described. In examples, a color comparison graphical user interface (GUI) is operated. The GUI displays a color of a sample object. Further, the GUI displays a color of a reference object. Further, the GUI displays a device independent color difference between the sample color and the reference color.
