An image processing apparatus includes a controller configured to perform: setting characteristic information including first characteristic information and second characteristic information; and converting a target image data using the characteristic information. The first and second characteristic information correlate input values with output values in a specific color space. The input values includes a specific input value within a specific range. The specific input value is correlated with a first specific output value by the first characteristic information, and is correlated with a second specific output value by the second characteristic information. The first specific output value indicates that a colorant consumption quantity for the specific input value is changed from an original colorant consumption quantity by a first colorant quantity. The second specific output value indicates that the colorant consumption quantity is changed from the original colorant consumption quantity by a second colorant quantity different from the first colorant quantity.

An image forming apparatus includes a printer engine, a sensor and a processor. The printer engine forms an image. The sensor outputs vibration information associated with a vibration of the printer engine. The processor determines whether at least one component of the printer engine has an abnormality based on the output vibration information.

An image forming apparatus and an image forming method are provided. The image forming apparatus includes a printing engine to form an image, a step motor to drive the printing engine, a driving circuit to provide a constant current to the step motor and sense a voltage corresponding to a magnitude of the constant current provided to the step motor, and a processor to calculate a temperature of the step motor based on the voltage sensed by the driving circuit during an excitation period of the step motor and control an operation of the image forming apparatus based on the calculated temperature.

An image forming apparatus, including: a light source including a plurality of light emitting points and configured to emit light beams; a photosensitive member configured to rotate in a rotation direction so that a latent image is formed thereon with the light beams; a rotary polygon mirror configured to rotate around a rotation axis and having a plurality of mirror faces each configured to deflect the light beams so that the photosensitive member is scanned with the light beams; a detector configured to detect temperature; and a correction unit configured to correct image data of an input image by using a deviation amount, in the rotation direction of the photosensitive member, of the light beams deflected by each of the plurality of mirror faces, wherein the correction unit obtains the deviation amount according to the temperature detected by the detector.

An image processing apparatus includes a processing unit that converts first input image data for a first region and second input image data for a second region to reduce a difference between first region recorded image density and second region recorded image density, and generates dot position data of a dot to be generated in each of the first and second regions based on the dot data after the conversion processing. The acquisition unit acquires edge information indicating a first object pixel edge of an image pixel for the first region and a second object pixel edge of an image pixel for the second region. Based on the acquired edge information, conversion and generation processing are performed in such a manner that a color signal of an edge pixel is increased/reduced to a degree lower than a degree to which a color signal of a non-edge object pixel is increased/reduced.

Disclosed is a guidance information display device, including: a display unit; a camera unit; an action detecting unit to detect a specific action of a user; and a control unit to instruct the display unit to display guidance information when the specific action is detected by the action detecting unit and a specific instrument to be operated is shot by the camera unit, the displayed guidance information corresponding to a combination of the detected specific action and the shot instrument to be operated.

An information processing apparatus capable of executing adjustment of an image formation position at a timing determined based on the number of printed sheets according to a user's request. Adjustment modes for use in adjusting geometrical characteristics of an image which is printed on a sheet are displayed for causing an image forming apparatus to print an adjustment chart. A controller receives first information indicating whether or not to execute a first adjustment mode for causing the image forming apparatus to print the adjustment chart based on the number of sheets on which images have been printed by the image forming apparatus, and receives second information indicating whether or not to execute a second adjustment mode for causing the image forming apparatus to print the adjustment chart based on a result of detection by a temperature sensor provided in the image forming apparatus.
