The present disclosure relates to a focus tracking system and method. The system comprises: a primary camera comprising a first focus adjustable lens and a first focus adjusting servo motor driving the first focus adjustable lens to perform focus adjusting; a secondary camera comprising a second focus adjustable lens and a second focus adjusting servo motor driving the second focus adjustable lens to perform focus adjusting, coded aperture is installed inside the second focus adjustable lens, the secondary and primary camera have equivalent optical parameters; a synchronization system performing frame level synchronization between images of the primary and secondary camera to obtain frame-level synchronized primary and secondary camera images; a focus control system calculating out-of-focus offset utilizing coded patterns of the coded aperture and out-of-focus images in the frame-level synchronized secondary camera images, sending focus adjusting signals to the first and second focus adjusting servo motor based on the out-of-focus offset.

An image processing apparatus includes a processor configured to adjust a reproduction parameter for correcting image visibility by changing a degree by which the reproduction parameter is to be changed from a reference value in accordance with a ratio of a second color gamut to a first color gamut. The first color gamut indicates a range in which an image is expressible by a first device. The second color gamut indicates a range in which an image is expressible by a second device.

An information processing apparatus includes a processing section that generates preview data for a preview of a print image by using raster data obtained by performing RIP processing on image data, and a storage section that stores the preview data, in which the image data has a spot color region represented by using a plurality of colors including at least one spot color as a region corresponding to one pixel of the preview data, and when a color replacement of the at least one spot color is performed, the processing section records a color value using an output color of the color replacement in the one pixel.

The application relates to a method for controlling a printing process for printing a decorative target image on a substrate, comprising providing the decorative target image to be printed in the printing process by at least one decorative parameter data set, simulating the printing process in a simulation step based on the decorative parameter data set, at least one printing process parameter data set and stored historical printing data sets, such that a digital decorative image is generated, verifying the generated digital decorative image based on the decorative target image to be printed and at least one verification criterion, and if the verification criterion is met, outputting the printing process parameter data set used in the simulation step for performing the printing process.

Examples herein relate to monitor calibration. In some examples, monitor calibration can include a scaler processing resource and a memory resource storing machine readable instructions to cause the scaler processing resource to record, by a sensor included on a monitor, color measurements of the monitor in response to receiving record instructions from an external computing device, transmit the recorded color measurements to the external computing device, receive calibration instructions from the external computing device based on the recorded color measurements, and calibrate the monitor using the calibration instructions received from the external computing device.

An image correction device includes a reception unit, a detection unit and a correction unit. The reception unit receives a first-image and a second-image, which are obtained by a first-imaging device and a second-imaging device, and an imaging condition that is at least one piece of information on an imaging date and time or information on an imaging location corresponding to each of the first-image and the second-image. The detection unit detects the same scene between images indicated by the first-image and the second-image based on the imaging conditions corresponding to each of the first-image and the second-image. The correction unit extracts, from each of the images indicated by the first-image and the second-image corresponding to the same scene, a common subject which is common between the images, and performs, on the corresponding image, color correction of making colors of the extracted common subject similar to each other.

A system, method, and computer program product are provided for digital photography. In use, a digital package comprising two or more images, metadata, and a function or parameter is received. A first action is performed on the two or more images, wherein the first action includes at least one of: a recognition of at least one object within the two or more images; a determination of a location based on the recognition; or an identification of information associated with the at least one object. A second action is performed on the two or more images. A synthetic image is rendered based on the two or more images, the first action, and the second action.

A method for calibrating the color space on multiple displays in a computing system includes determining a native color space for each of multiple displays; dynamically selecting a target color space to implement on each of the multiple displays based at least in part on the determined native color space of each one of the multiple displays; and instructing one of the multiple displays to map the associated native color space to the target color space.

Relative calibration is used to generate tone reproduction curves (TRCs) at multiple printing devices. A first calibration is performed for a first paper at a first printing device to generate a first TRC. A second calibration is performed for the first paper at a second printing device to generate a second TRC. A third calibration is performed for a second paper at the first printing device to generate a third TRC. A device difference dataset is determined using the first TRC and the second TRC. A paper difference dataset is determined using the first TRC and the third TRC. The device difference dataset and the paper difference dataset are used to determine a fourth TRC for the second paper at the second printing device, thereby eliminating the need for further calibration operations.
