Color calibration chart acquisition
First Claim
1. A method to guide a user acquiring a reproduction of a color calibration chart, the method comprising:
- at a imaging device including a camera for acquiring a video and a display to display the video,processing in real-time frames of the video;
upon frames of the video including a reproduction of the color calibration chart, displaying user feedback to dynamically guide the user to make adjustments in the video acquisition so as to capture a color calibration chart reproduction within a selected quality threshold; and
upon capturing a color calibration chart reproduction within the selected quality threshold, signaling that the color calibration chart reproduction has been captured,wherein upon processing first frames of the real-time frames, a first color calibration chart reproduction is detected that is outside the selected quality threshold, in response to which the user is dynamically guided to make the adjustments in the video acquisition,and wherein second frames of the real-time frames are acquired after the user has made the adjustments, and a second color calibration chart reproduction is detected that is within the selected quality threshold.

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.

5. A computer software product comprising a non-transitory tangible medium readable by a processor, the medium having stored thereon a set of instructions for obtain a reproduction of a color calibration chart, comprising:
-
a set of instructions which, when loaded into a memory and executed by the processor, causes processing a video acquired by an imaging device; a set of instructions which, when loaded into a memory and executed by the processor, causes analyzing the video to automatically detect a reproduction of the color calibration chart within one or more first frames of the video; a set of instructions which, when loaded into a memory and executed by the processor, causes, upon detection of a reproduction of the color calibration chart, determining whether color calibration chart reproduction quality is within a selected quality threshold; and a set of instructions which, when loaded into a memory and executed by the processor, causes, upon determining that color calibration chart reproduction quality is not within a selected threshold, providing user feedback, 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. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)

13. An imaging device, comprising:
-
a camera; a display; a video acquisition engine to acquire a video via the camera; a video rendering engine to display a video stream based on a video acquired via the camera; and a chart capture engine to automatically capture a reproduction of a color calibration chart from the video acquired via the display, the chart capture engine continuously processing the video to; automatically detect a color calibration chart reproduction in a first frame of the video; upon detecting the color calibration chart reproduction, determining whether the color calibration chart reproduction is within a selected quality threshold; and upon determining that the color calibration chart reproduction is outside the selected quality threshold, guide a user to make adjustments in the video acquisition engine, detect an additional color calibration chart reproduction in a second frame of the video acquired after the user has made the adjustments, and determine whether the additional color calibration chart reproduction is within the selected quality threshold. - View Dependent Claims (14, 15)
