Abstract: According to examples, an apparatus may include a processor and a memory on which are stored computer-readable instructions that, when executed by the processor, may cause the processor to access a master image to be printed and receive a scanned image corresponding to the master image. The processor may identify a defect in a scanned image region of interest (ROI) based on the master image. A type of the scanned image ROI may include a raster ROI, a symbol ROI, a background ROI, and/or a color vector ROI, and the identified defect may be associated with the type of the scanned image ROI. The processor may determine a severity of the identified defect of the scanned image and may output the determined severity.

Abstract: Various implementations disclosed herein include methods, electronic devices, and systems for performing perceptual-based color correction based on chromaticity values. To that end, in some implementations, a method is performed at an electronic device with one or more processors, a non-transitory memory, and a see-through display. The method includes determining a chromaticity value associated with ambient light from a physical environment. The chromaticity value quantifies the ambient light. The method includes determining a set of color correction values based on a function of the chromaticity value and image data. The set of color correction values and the chromaticity value together satisfy one or more perceptual criteria. The method includes modifying the image data in order to generate display data based on a function of the set of color correction values. The method includes displaying the display data on the see-through display.

Abstract: A colorant value adjustment method is disclosed. The method comprises obtaining data defining colorant values for a plurality of print addressable locations representative of pixels of an image to be printed during a printing operation, wherein each colorant value is representative of an amount of colorant to be delivered from a print nozzle to a corresponding print addressable location as the print nozzle moves between the print addressable locations during the printing operation. The method comprises determining, based on the obtained data, a measure of time that the print nozzle is not to deposit colorant immediately prior reaching a first print addressable location. The method comprises determining, based on the determined measure of time, an adjustment to be applied to the colorant value at the first print addressable location. The method comprises applying the adjustment to the colorant value for the first print addressable location. An apparatus and a machine-readable medium are also disclosed.

Abstract: In accordance with some implementations, a method is performed at an electronic device with one or more processors, a non-transitory memory, and a see-through display. The method includes determining a plurality of light superposition characteristic values associated with ambient light from a physical environment. The plurality of light superposition characteristic values quantifies the ambient light. The method includes modifying image data in order to generate modified image data, based on a function of the plurality of light superposition characteristic values and a reference perceptual gamut. The method includes transforming the modified image data into display data based on a function of a portion of the plurality of light superposition characteristic values and a reference physical gamut that is associated with the see-through display. The method includes displaying the display data on the see-through display.
