An image processing apparatus comprises a processor for quantizing multi-gradation image data with regard to each of R, G and B to convert it into pseudo halftone output image data. First, the processor performs a first quantization for deciding a dot appearance pattern C[k] with respect to an observed pixel of the multi-gradation image data with regard to blue. After that, the processor performs a second quantization for deciding the dot appearance pattern of green with respect to the observed pixel so as to make an anti-correlation with the dot appearance pattern C[k] decided by the first quantization.

Image processing apparatus and image processing method

An image processing apparatus includes: a recording rate determining section for determining a recording rate of each of a plurality of dot types having different densities per unit area from each other according to an input value including a multi-gradation image data, the input value being quantized for forming a dot of the plurality of dot types; a dot formation judging section for judging whether the dot is to be formed on each pixel based on a sum total of each recording rate of the plurality of dot types; and a dot selecting section for selecting a dot type among the plurality of dot types having different densities per unit area from each other to a pixel on which the dot formation judging section judges that the dot is to be formed, wherein an image is formed according to an arrangement distribution of the dot.

A recording method comprising the steps in the following order of: correcting a curl of a recording medium by applying heat and pressure to the recording medium; and forming an image on the recording medium by jetting ink onto the recording medium.

Ink jet recording apparatus, ink-jet recording method and ink jet recording medium

The present invention concerns an image recording apparatus, which records images on a roll-type recording medium. The image recording apparatus includes a recording device to record an image on a recording medium by emitting ink onto the recording medium; a cutting member to cut the recording medium after the recording device records the image, the cutting member being disposed downstream in respect to the recording device in a conveying-direction of the recording medium; a second conveyance member to convey the recording medium, the second conveyance member being disposed at a position located between the recording device and the cutting member in the conveying-direction of the recording medium; and a conveyance controller to control the second conveyance member so as to generate a slack of the recording medium at a section between the recording device and the second conveyance member in the conveying-direction of the recording medium.

Image recording apparatus

An image data processing method for ink jet printer comprising the steps of obtaining an allowable amount of ink in accordance with inputted image data and characteristics of a medium for forming an image; selecting and ink jetting domain and fixing the amount of ink in the selected ink jetting domain at a specified value, on the basis of the allowable amount of ink; and practicing a quantization processing with the amount of ink in the ink jetting domain fixed at the specified value.

Image data processing method for ink jet printer

A film image editor for editing plural photographic film images. The editor includes: a scanner for reading images in any one of a plurality of different picture sizes from a developed photographic film; a picture size detecting circuit for detecting a picture size of each of the images based on a density variation information of each of the images; an editing interface for editing the image in the detected picture size according to an input operation by an operator; and an output device for outputting the image which is edited by the editing interface.
