A computing device may include a processor and a display device communicatively coupled to the processor wherein the display device includes a wide gamut mode wherein the wide gamut mode comprises a plurality of different gamut profiles and wherein the display device adjusts from a first gamut profile to a second gamut profile based on a gamut profile associated with an image to be represented on the display device.

Disclosed is a method for producing metadata, comprising: acquiring a first image and a second image which have different gamuts; acquiring at least one of white point information and gamut information with respect to the second image; correcting the first image on the basis of the acquired information; and producing metadata on the basis of the correspondence relationship of color information between the corrected first image and the second image.

An image processor includes: a first hardware processor that extracts irreversible first image feature information from a read image of a printed matter; and a second hardware processor that selects second image feature information most similar to the first image feature information among a plurality of pieces of irreversible second image feature information extracted by the first hardware processor from read images of a plurality of printed matters printed previously, and acquires, as a comparison result, print setting information associated with the second image feature information.

A pattern and spectrum security one-time printing of packaging verification method for verifying the authenticity of an external packing container of a commodity, which external packing container is printed with a security pattern on the surface using a specific spectrum of tangible fluorescent ink. The user checks the location of the security pattern by visualizing the tangible fluorescent ink on the external packing container, and then uses image capturing device to shoot the security pattern through a filter to capture the pattern image of the tangible fluorescent ink, a processor of the identification system loads in the captured pattern image, a software program in the processor matches the spectral band and shape of the captured pattern image with storage data in the database to verify the authenticity of the security pattern. The user can identify the authenticity of the commodity, enhancing commodity security and reducing the risk of being forged.

A method of generating metadata includes: obtaining a first image and a second image respectively having different color gamuts; obtaining at least one of information regarding a white point and information regarding the color gamut of the second image; correcting the first image based on the obtained information; and generating the metadata based on a correspondence relation between color information of the corrected first image and color information of the second image.

A system and method adaptively lossy compresses image data by receiving a pixel of image data and meta data indicating a type of object that generated the pixel of image data, the pixel of image data includes a first byte having most significant bits of image data and a second byte having least significant bits of image data; electronically determining if the meta data associated with the pixel of image data is associated with a noisy image or indicates that the pixel of image data was generated by a specific type of object; electronically modifying the pixel of image data, when it is determined that the meta data is associated with the pixel of image data is associated with a noisy image or indicates that the pixel of image data was generated by a specific type of object, by setting a predetermined number of low bits of the pixel of image data to zero.

To allow a better coordination between an image creation artist such as a movie director of photography and the final viewer, via a receiving-side display and its built-in image processing, a method of adding image defining information to an input image signal (I) comprises receiving descriptive data (D) that includes at least luminance value information on the one hand, and a regime descriptor (rd) on the other hand; and encoding into an output description data signal (DDO), relatable to an output image signal (O) based upon an input image signal (I), of the descriptive data (D) in a technical format standardized to be intended for use by a receiving-side display to control its image processing for changing the color properties of its rendered images.

To allow a better coordination between an image creation artist such as a movie director of photography and the final viewer, via a receiving-side display and its built-in image processing, a method of adding image defining information to an input image signal (I) comprises showing the input image (I) to a human operator; receiving via a user interface (303, 308) descriptive data (D) from the human operator, the descriptive data (D) including at least luminance value information on the one hand, and a regime descriptor (rd) on the other hand; and encoding into an output description data signal (DDO), relatable to an output image signal (O) based upon the input image signal (I), of the descriptive data (D) in a technical format standardized to be intended for use by a receiving-side display to control its image processing for changing the color properties of its rendered images.

An image forming apparatus includes an image forming device, a gradation adjustment mark adder and a hardware processor. The hardware processor monitors and adjusts a gradation characteristic based on a result of scanning a gradation adjustment mark. The hardware processor makes a determination as to whether to form the gradation adjustment mark overlapping an image area of an image based on image data. If it is determined to form the gradation adjustment mark overlapping the image area, the hardware processor controls the gradation adjustment mark adder to add gradation adjustment mark information to the image data in the image area.
