摘要:
An image processing system that facilitates process of color universal design that enables people with color amblyopia to recognize color difference as image pattern without changing characteristic of coloration and gradation and people with no disabilities who look the same image to feel less discomfort. A hue determining unit 102 determines hue of image data, and a selecting unit 105 selects halftone processing in accordance with the determined hue. If the selected halftone processing is dithering process that uses AM dithering, a halftone processing unit 106 executes halftone processing with different line per inch depending on the determined hue.

An image processing method includes converting multilevel data of an image into a dot pattern using a multilevel error diffusion process. The conversion includes determining a pixel corresponding to an abnormal nozzle based on abnormal nozzle information provided for each of droplet sizes supported by nozzles of an image forming apparatus; preventing jetting of a droplet onto the determined pixel; distributing a quantization error of the determined pixel calculated in the multilevel error diffusion process to neighboring pixels; and if extra-large droplets with a droplet size greater than the droplet size of a full-size droplet capable of filling a pixel are to be formed in the neighboring pixels as a result of distributing the quantization error, removing one or more of the extra-large droplets or reducing the droplet size of one or more of the extra-large droplets.

An objective of the present invention is to provide methods for synthesizing polynucleotides comprising an unknown nucleotide sequence in a region containing their 5′-end. By using a single gene-specific primer, nucleotide sequences complementary to each other are added respectively at the 5′-and 3′-ends of a desired polynucleotide, to synthesize a desired polynucleotide. Requisite nucleotide sequences can be easily added by incubating with a primer, double-stranded DNA, and template-dependent DNA polymerase. By applying the present invention to 5′ RACE, genes expressed in a low-level, which cannot be obtained by known methods, have been efficiently obtained.

A disclosed image processing apparatus includes an adjusting unit configured to convert input image data into image formation data, an arithmetic unit configured to calculate an image formation ink cost based on the converted image formation data, and a determining unit configured to compare the calculated image formation ink cost with a black-and-white image formation ink cost, wherein the calculated image formation ink cost is fixed based on a determination result of the first determining unit.
摘要:
In an image-processing method and apparatus, dots forming a step-change part of an outline of an image of characters and/or graphics which image is subjected to half-tone processing are detected, and dots surrounding the detected dots forming the step-change part are transformed into respective dot data each having a size that is smaller than a size of the detected dots forming the step-change part. In the image-processing method and apparatus, one of different transformation methods is selected according to an inclination of the outline in order to produce the dot data in the transforming.

In a multivalued read only memory device, a plurality of memory cells each for storing N (N=3, 4, . . . ) information states corresponding to N threshold voltages are connected to word lines, and a plurality of reference memory cells for storing said N information states are connected to a reference word line. A word line selecting circuit selects one of the word lines and selects the reference word line, so that the voltages at the selected word line and at the reference word line are gradually increased. A latch timing generating circuit generates latch timing signals in accordance with output signals of the reference memory cells, and a latch circuit latches an output signal of the memory cells in accordance with the latch timing signals. An encoder circuit generates output data in accordance with output signals of the latch circuit.
摘要:
An oral composition contains mutanase prepared from a culture which is obtained by cultivating a mutanase-producing microorganism belonging to the genus Bacillus having negative protease producibility. The oral composition is effective for suppressing dental plaque formation while the mutanase possesses commercially acceptable stability in the oral composition.
