摘要:
An image processing apparatus includes an input section, and a screen processing section. The input section inputs image information. The screen processing section performs screen processing on the input image information with a threshold matrix. A plurality of threshold values are arranged in the threshold matrix so that if the threshold values are colored in an ascending order or descending order. The threshold matrix represents at least one selected from the group consisting of capital alphabets ‘A’ to ‘Z’, lower case alphabets ‘a’ to ‘z’ and numeric characters ‘0’ to ‘9.’

An image-forming device which is equipped with an image-holding member, an exposure section provided with plural light-emitting portions arranged in a first direction, a movement section that relatively moves the exposure section and the image-holding member in a second direction that intersects with the first direction, and a light-emission control section. The light-emission control section causes the plural light-emitting portions to periodically emit light in accordance with image data representing an image that is to be formed on the image-holding member, to form the image on the image-holding member. The light-emission control section varies a light-emission period during formation of the image, so as to correct for periodic fluctuations within the image of at least one of density and magnification ratio in the second direction.

An image forming device includes a rotating polygon mirror and a correcting component that corrects misregistration of an image region in a predetermined direction. The correcting component carries out the correction by correcting image data used in modulating light beams reflected and deflected by any one reflecting surface among plural reflecting surfaces provided at the rotating polygon mirror, where the light beams scann a body-to-be-illuminated in the predetermined direction, correcting image data by each data unit used in modulating light beams which are reflected and deflected at the same reflecting surface, and correcting image data in accordance with a misregistration amount in the predetermined direction of the image region formed on the body-to-be-illuminated by the light beams which are reflected and deflected, where the misregistration amount is measured in advance for each reflecting surface of the rotating polygon mirror.

A multifunction system has advanced functions and high speed capability and is excellent in expandability. The multifunction system includes a controller, an IIT, an IOT, and a light distributing device. For a print job, print data outputted from the controller is converted into optical signals, which enter a light distributing device and are transmitted to the IOT of the emission side. The IOT prints the received data onto a printer. For a copy job, copy data outputted from IIT is converted into optical signals, which enter the light distributing device, and are transmitted to the IOT of the emission side. For a scan job, scan data outputted from the scanner is converted into optical signals, which enter the light distributing device, and are transmitted to the controller of the emission side. The controller processes the received data.

An image forming apparatus includes: a latent image forming unit scanning and exposing an image carrier according to image data, to form a latent image; a transfer body on which a toner image is transferred and a reference index for setting an output start time point of the image data is formed; a detecting unit facing the reference index and outputting a detection signal changing in accordance with passing of the reference index; and a controller controlling the output start time point with the detection signal. The controller starts a first period during which change of the detection signal is ignored, according to first change of the detection signal, starts a second period after the first period, regards second change of the detection signal occurring first in the second period as a reference of the output start time point, and ignores change of the detection signal after the second change.

A set value output circuit includes a first output unit and a second output unit. The first output unit outputs a signal input to a first input when a first timing signal is input to a second input, and continues to output the signal until a next first timing signal is input. The second output unit outputs the signal input to a third input when the second timing signal is input to a fourth input, and continues to output the signal until a next second timing signal is input. A selection unit inputs a selected timing signal as the second timing signal to the fourth input. A control unit inputs the first timing signal to the second input, so that a set value for an image to be formed next is output during image formation using the signal output from the second output.
