Abstract

There is described an image processing apparatus, which makes it possible not only to eliminate the deterioration of the perceptibility, but also to determine the pages being suitable for applying the predetermined image processing.

Abstract

When conveying an envelope, a posture of the envelope is corrected by hitting a closed portion of the envelope, which is opposite side of an opened portion of the envelope, against a nip portion between upper and lower rollers of the pre-registration rollers and the envelope is then conveyed with the envelope being nipped by the upper and lower rollers of the pre-registration rollers. The upper and lower rollers of the pre-registration rollers nip the envelope to remove air from the envelope. When setting an envelope mode to control a conveying speed of the envelope based on a coverage rate of an image to be formed on the envelope, the conveying speed of the envelope is controlled by adjusting a rotation speed of the registration rollers based on the coverage rate of the set envelope mode.

Abstract

An image processing apparatus includes a probability conversion unit, a processor, and a threshold conversion unit. The probability conversion unit receives an initial pattern and converts it into a probability distribution space. The processor performs weighting on a density distribution space indicating a density of pixels determined to be dotted using the probability distribution space, determines pixels to be dotted and an order of the dotting in the weighted density distribution space, updates the probability distribution space until the order for all pixels in the initial pattern is determined, and repeats the determination using the updated probability distribution space. The threshold conversion unit converts the order of dotting into thresholds to obtain a threshold matrix. The probability conversion unit uses a threshold matrix preliminarily created to form a halftone dot as the initial pattern.
