An image processing apparatus has a determining unit that determines based on a print job whether an image is to be recorded by ejecting a treatment liquid, a generating unit that based on image data generates print data by converting portions of each of the color data that are capable of being replaced by using black ink droplets into black data at a predetermined ratio, and a ratio setting unit that sets the ratio of the generating unit when the determining unit determines that the image is to be recorded by ejecting the treatment liquid so that the ratio is higher than that in other cases.

Image processing apparatus and droplet ejection apparatus

A coloring material recording device comprises a plurality of image recording elements and a control unit. The plurality of image recording elements record with a plurality of coloring materials on a recording medium and form an image, and one of the plurality of image recording elements is provided for each of the coloring materials. The control unit controls the plurality of image recording elements such that detection images of at least two coloring materials of the plurality of coloring materials overlap each other on the recording medium.

Coloring material recording device, coloring material recording program, and image forming apparatus

An image processing device converts multi-gradation image data to low-gradation image data for outputting an image of a dot pattern that is formed by a high-density first part formed in a band shape by dots connected in a predetermined direction and a low-density second part formed by randomly arranged dots.

Image processing device, image output apparatus, and storage medium storing image processing program

An image reading apparatus for obtaining a digital image having gradation of binary-level or multi level in a computer, a word processor, a digital copying machine, or like apparatus. The image reading apparatus includes an imaging device, an optical unit located for exposing the imaging device and capable of moving in two directions perpendicular to each other, a reading operation control unit for controlling a first reading operation in which whole information of the original image is read, and a second reading operation in which division image information in division areas of the original image is read, a resolution setting unit for setting a resolution in the second reading operation, and a data processing unit for connecting a plurality of division image information sets which are read in a plural number of times of the second reading operations, as a front view image information on the original image.

Image reading apparatus providing high quality images through synthesis

A method and apparatus for reproducing half-tone images by converting continuous-tone image data into a multi-valued level density code using a predetermined threshold or thresholds includes adding an output adjusting error to a difference error between image data of a target pixel and a threshold level and diffusing the difference error to which the output adjusting error has been added into pixels surrounding the target pixel.
