Trace information showing a fact that an illegal output request has been issued from any one of data processing apparatuses is managed. Under an output environment such that an output apparatus is shared from a plurality of data processing apparatuses, when it is detected that a kind of data received by a CPU is specific data such that an output is legally limited, information to identify a transfer source side of the specific data or the received data is preserved and managed in an RAM or the like.

Image processing apparatus, for limiting access to stored information to a system administrator, and method thereof

Image processing apparatus, method, and computer-readable storage medium for storing programs used therein

An image processing method comprises the steps of developing coded data into image data by analyzing them, at the same time, creating the positional information within one display of the image data, discriminating the area to embed a pattern that indicates a specific addition information therein in accordance with the kind of image data and the positional information created in the development step at the time of development, and embedding the information hardly discriminately by eye-sight in the area discriminated in the discrimination step.

Image processing apparatus and method therefor, and storage medium

This invention has as its object to reliably and efficiently add additional information to an input image even when a system for performing image processing of the input image may include a plurality of equipments having a function of adding additional information. In order to achieve this object, according to this invention, an image processing apparatus has generation means for generating image data, discrimination means for discriminating whether or not an externally connected equipment related to the image data generated by the generation means adds predetermined additional information to be hardly discernible by the human eye, adding means for adding the predetermined additional information to the image data generated by the generation means to be hardly discernible by the human eye in accordance with the discrimination result of the discrimination means, and output means for outputting the image data to which the predetermined additional information is added by the adding means or the image data generated by the generation means.

Image processing and method, and storage medium

A print control apparatus for controlling a printing operation on the basis of an instruction sent from an information processing apparatus including first input unit for inputting an instruction by a user, operational-environment setting unit for setting an operational environment in one of first and second modes, wherein setting of the environment based on the instruction from the information processing apparatus and the first input unit is permitted in the first mode, and wherein setting of the environment based on the instruction from the information processing apparatus is permitted and setting of the environment based on the instruction from the first input unit is prohibited in the second mode. A control unit is for terminating the setting of the operational environment based on the instruction from the first input unit in a case where it is instructed to switch the first mode to the second mode while the setting of the operational environment is performed based on the instruction from the first input unit in the first mode.

Display apparatus and control method therefor

There is disclosed a laser driving device capable of providing a stable laser emission regardless of the ambient temperature, by supplying a laser element with a first current and a second bias current with a controlled ratio therebetween.

Laser driving device

An image forming apparatus includes an recording medium, a beam radiating unit for radiating a beam to form an image on the recording medium, and a drive unit for driving the recording medium, wherein the drive unit has a stepping motor for performing a step operation of the recording medium.
