An image processing apparatus caused to perform controlling for making a first lightness compression ratio of a first image region higher than a second lightness compression ratio of a second image region based on a setting for printing an image using a spot color that is different from process colors being set, the first image region not corresponding to the spot color in the image, and the second image region corresponding to the spot color in the image, and controlling for displaying the image after the first controlling is executed.

Non-transitory computer readable storage medium, image processing apparatus, and control method of image processing apparatus for settings for performing printing using spot colors

An image capturing unit captures an image including an embedded image that is printed on the basis of image data in which at least a color component has been modulated according to additional information. An adjustment unit adjusts a white balance of the image captured by the image capturing unit on the basis of an adjustment value associated with the embedded image. A processing unit processes image data of the image captured by the image capturing unit whose white balance has been adjusted by the adjustment unit to read the additional information in the image captured by the image capturing unit.

Mobile terminal having a light source and an application to extract embedded information from an illuminated printed image and method

A control method for an image processing apparatus that generates a plurality of pieces of album data including a common page, which is a page common to all of the plurality of pieces of album data, and an individual page, which is a page not common to all of the plurality of pieces of album data, includes performing control in such a manner that cover image data corresponding to an image to be placed in a cover of each album is selected as individual image data or common image data.

Image processing apparatus, control method, and storage medium

Information processing apparatus that illuminates a printed image during capture when embedded information is to be processed, information processing system, information processing method, and storage medium

Information processing apparatus with a light that illuminates more actively while capturing a printed image when embedded additional information is to be processed, information processing system, information processing method, and storage medium

The image processing apparatus includes: a color conversion unit configured to convert an input color space of the document image data into a device-dependent color space specified by the plurality of color materials; and an output unit configured to output the document image data converted into the device-dependent color space, and the color conversion unit performs, in a case where the document image data includes a first kind of object and a second kind of object different from the first kind, the conversion by selectively applying a first color conversion method of converting data corresponding to the first kind of object into data represented in a first color space and a second color conversion method of converting data corresponding to the second kind of object into data represented in a second color space different from the first color space within one print job.

Image processing apparatus, image processing method, and storage medium

The first image data is converted into the second image data defined by a color space that depends on an output apparatus that outputs image data. Additional information is multiplexed on the converted second image data by using a multiplex parameter.

Information processing apparatus, information processing method, and non-transitory computer-readable storage medium storing program

A control method for an image processing apparatus that generates a plurality of pieces of album data corresponding to a plurality of albums includes automatically selecting at least one piece of image data out of a plurality of pieces of image data as common image data corresponding to an image to be placed in a common page, which is a page common to all of the plurality of albums, based on an evaluation that is based on a first factor, and automatically selecting at least one piece of image data out of the plurality of pieces of image data as individual image data corresponding to an image to be placed in an individual page, which is a page not common to all of the plurality of albums, based on an evaluation that is based on a second factor.

To make it possible to easily extract additional information from printed matter by using a built-in camera of a mobile terminal. An information processing apparatus that reads additional information by capturing printed matter in which the additional information is embedded by using a built-in camera, including: a control unit configured to acquire a first captured image obtained by capturing the printed matter under a first image capturing condition and a second captured image obtained by capturing the printed matter under a second image capturing condition different from the first image capturing condition; and an extraction unit configured to extract the additional information by analyzing the first captured image and the second captured image.

Information processing apparatus, control method thereof, and storage medium

There is provided a control method for an image processing apparatus that generates a plurality of pieces of album data corresponding to a plurality of albums, the plurality of pieces of album data including a common page, which is a page common to all of the plurality of pieces of album data, and an individual page, which is a page not common to all of the plurality of pieces of album data. At least one image data group out of at least one image data group specified as a common image data group is controlled in such a way as not to be specified as an individual image data group.

An image processing method includes: a first obtaining step of obtaining data of an image; a second obtaining step of obtaining additional information; a third obtaining step of obtaining information related to a printable area of a print medium on which the image based on the data obtained in the first obtaining step is printed; determining step of determining a position where the obtained additional information is embedded in the image on the basis of the information obtained in the third obtaining step; and embedding step of embedding the additional information with reference to the determined position.

Image processing method that determines a number of blocks for embedding information based on a size of an image to be printed, image processing apparatus, and storage medium

Information processing apparatus that performs auto white balance if additional information is not extracted from a captured image, information processing system, information processing method, and storage medium

Information processing apparatus, information processing system, information processing method, and storage medium

According to the present invention, patch data is printed in such a manner that the length of a low-optical-density patch is small and the length of a high-optical-density patch is large. In addition, the measurement is performed by a sensor that measures at a constant scanning speed. Therefore, SN of a dark patch having a high optical density is improved, and a patch chart can be measured in a short time.
