An image processing apparatus includes a processing unit that converts first input image data for a first region and second input image data for a second region to reduce a difference between first region recorded image density and second region recorded image density, and generates dot position data of a dot to be generated in each of the first and second regions based on the dot data after the conversion processing. The acquisition unit acquires edge information indicating a first object pixel edge of an image pixel for the first region and a second object pixel edge of an image pixel for the second region. Based on the acquired edge information, conversion and generation processing are performed in such a manner that a color signal of an edge pixel is increased/reduced to a degree lower than a degree to which a color signal of a non-edge object pixel is increased/reduced.

In one example, an apparatus includes a plate configured to pivot about a pivot point, a pulley coupled to a first planar side of the plate and configured to rotate a belt, a motor coupled to the first planar side of the plate and configured to drive the pulley, and a torsion spring coupled to a second planar side of the plate that is opposite the first planar side and configured to apply tension to the belt.

Provided are a decorative member manufacturing apparatus and method for manufacturing a decorative member, which are capable of reducing an amount of fluid used without impairing a texture of a decorative layer.

In the decorative member manufacturing apparatus and method for manufacturing a decorative member of the present invention, a fluid cured by receiving light is jetted from a jetting part toward a surface of a base material, the fluid which has landed on respective portions is irradiated with light from an irradiation part to form a cured convex portion constituting the decorative layer on the respective portions on the surface of the base material, and the jetting part is controlled based on control data for forming the cured convex portion having a set thickness in the respective portions. In addition, correction processing is performed by a correction part on the control data, the correction processing being a process of reducing a thickness corresponding to a spatial frequency equal to or smaller than a set value, in a correspondence relationship between the thickness and spatial frequency of the cured convex portion which is formed in a case where the jetting part is controlled based on the control data.

An image processing apparatus processes data for printing an image by relatively moving a printing unit and a printing medium. The printing unit includes a plurality of printing elements arranged in a first direction, and the relative movement is in a second direction that intersects with the first. The apparatus includes an acquisition unit to acquire image data corresponding to an image of one page, a first processing unit to process first image data corresponding to a first processing area of the image by using a common parameter for each pixel arranged in the second direction, for generating first print data that is used for the printing unit, a second processing unit to process second image data corresponding to a second processing area of the image by using a common parameter for each pixel arranged in the second direction, for generating second print data used for the printing unit.

A reflected light amount from a patch under a first light source is acquired, and a reflected light amount from the patch under a second light source whose wavelength band is different from the first light source is acquired. The type of a printing medium on which the patch is printed is determined based on the ratio of the two acquired reflected light amounts.

To generate a dot pattern whose deterioration of a feeling of granularity, density unevenness, and streaks are unlikely to be recognized visually by more effectively suppressing a change of an overlap of ink droplets on a printing medium. Halftone image data representing a dot pattern of each of two or more kinds of dot different in density reproduction is acquired. Then, in a case where there is a possibility that the contact state between dots changes due to a landed-dot shift of ink in a plurality of specific dots on a condition that dots are formed in accordance with a dot pattern in the halftone image data, the plurality of specific dots is replaced with dots of another kind whose number is less than or equal to that of the plurality of specific dots.

An image capturing unit includes a sensor unit that image-captures a predetermined area including a subject; and a reference chart unit that is arranged in the predetermined area and captured with the subject by the sensor unit.

There are provided a printing system, a method of generating a halftone processing rule, a method of acquiring a characteristic parameter, image processing device and method, a halftone processing rule, a halftone image, a method of manufacturing a printed material, an ink jet printing system, and a program which are capable of reducing an operation load of a user and acquiring a halftone processing rule appropriate for the printing system. A characteristic parameter acquisition chart including a pattern for acquiring characteristic parameters related to characteristics of the printing system is output, and the output characteristic parameter acquisition chart is read by image reading means. The characteristic parameters are acquired by analyzing the read image of the characteristic parameter acquisition chart, and halftone processing rules that define the processing contents of halftone processes used in the printing system are generated based on the acquired characteristic parameters.
