Patent ID: 8872923

Claim:
A method comprising: at a imaging device including a camera for acquiring a video and a display to display the video, the video of a physical color calibration chart physically located near a physical object within a scene, the color calibration chart adapted to permit identification of a color of interest of the object so long as the color calibration chart is within a selected quality threshold in the video; processing in real-time frames of the video; upon frames of the video including the color calibration chart, displaying user feedback to dynamically guide the user to make adjustments in the video acquisition so as to capture the color calibration chart within a selected quality threshold; and upon capturing the color calibration chart within the selected quality threshold, signaling that the color calibration chart has been sufficiently captured so that the identification of the color of interest of the object within the video is able to be determined, wherein if the color calibration chart is failed to be captured within the selected quality threshold, the identification of the color of interest of the object within the video is unable to be determined.
