Abstract
The present disclosure related to acquisition of color calibration charts. In at least some examples herein, an image of a calibration color chart is processed. A lighting condition of the color calibration chart may be automatically determined.
Claims20
A method comprising:
- automatically determining, by a processor, a lighting condition of an imaged, color calibration chart acquired by an imaging device;
- assessing whether the determined lighting condition corresponds to a selected lighting condition;
- and
- causing, by a processor, a signal via the imaging device, indicating whether the color calibration chart is imaged under the selected lighting condition.
1 more element
A computer software product comprising a tangible medium readable by a processor, the medium having stored thereon a set of instructions, the instructions including:
- a set of instructions which, when loaded into a memory and executed by the processor, causes to process an image of a calibration color chart;
- a set of instructions which, when loaded into a memory and executed by the processor, causes to automatically detect the color calibration chart in the image;
- and
- a set of instructions which, when loaded into a memory and executed by the processor, causes to automatically determine a lighting condition of the detected color calibration chart.
1 more element
A mobile imaging device comprising:
- a camera;
- a display to display an image acquired by the camera;
- an acquisition engine to process an image of a color calibration chart acquired by the camera;
- a lighting determination engine to determine lighting condition of the acquired color calibration chart;
- and
- a guiding engine to guide a user in the acquisition of the color calibration under a selected lighting condition.
