The power control system of the present invention include an image processing apparatusas an example of the information processing apparatus and a power consumption management apparatusthat manages the amount of power consumption of the image processing apparatus. The image processing apparatus, in power saving control based on a control mode according to the amount of power consumption, if execution of a job instructed by a user is restricted depending on a power saving setting received from the power consumption management apparatus, changes control content of the control mode to content that has been determined as a substitution for the control content for allowing the job to be executed.

Power control system and control method for the same

A color image forming apparatus is provided that forms an image by correcting registration shifts during an image forming process by using image data and which prevents toner from being blown away and scattered during a fixing process by thinning pixels without making an erroneous decision. When multivalued color image is binarized, the threshold is corrected by using information on grayscale level correction. Further, when trailing phenomenon prevention operation is performed on the binarized image data, the patterns to be used for pattern matching are changed and selected according to whether the subscan direction line shifting point lies within the reference window.

Apparatus and method for correcting registration errors and trailing phenomenon in a printed image

An image forming apparatus which is capable of suppressing occurrence of color moire. A second storage unit stores image data associated with at least two colors. A controller reads out the stored color-specific image data while designating a reading position in a sub scanning direction of the image data. A transfer unit transfers a color image onto a recording medium based on the read-out image data of each color. An image processing unit corrects the reading position in the sub scanning direction of the image data of each color according to profile data of each color defined based on position curve information in the main scanning direction of the transfer unit, when the controller reads out the image data. The controller regenerates the profile data if at least two pieces of the profile data satisfy a predetermined condition.

Image forming apparatus and image processing method therefor

In an MFP having a displaying unit smaller than that of a PC, it is very difficult to select an editing target from a plurality of objects. To accomplish this, an image containing a plurality of objects is displayed. Objects corresponding to a position designated on the displayed image are extracted (S). Individual images corresponding to the extracted objects are laid out and displayed (S). One of the individual images which are laid out and displayed is selected (S). Image processing is executed for the selected object.

Image processing apparatus and control method thereof

An image processing system includes a plurality of image processing sections for performing predetermined image processing on input image data and for outputting the processed image data. A header in which image processing information is described is added to the input image data in order to create packet data, and the created packet data is transferred sequentially to a plurality of image processing sections. A given image processing section inputs the transferred packet data, performs image processing on the image data in accordance with the image processing information described in the header, recreates packet data by adding a header in which the image processing information is rewritten to the image data after processing, and outputs the recreated packet data. Thus, even in a state in which the number of pieces of image data, the amount of the management information thereof, etc., are large, it is possible to easily manage image processing without imposing a large load on a CPU.
