Abstract: A supervising system for image forming apparatus includes a central control apparatus, a public communication network connected to the central control apparatus, a communication adaptor connected to the public communication network, and a plurality of image forming apparatus connected to the communication adaptor via a wired or a wireless interface. The supervising system further includes a mobile computer selectively connected to the wired or wireless interface directly or indirectly for executing communications of information between the central control apparatus and itself via the public communication network.

Abstract: A printed sheet measurement apparatus initially captures images on a reference sheet and a printed sheet to store respective image data. Next, both of the image data are displayed on a display element, and a pair of corresponding points are specified for each of the image data. A judgment is made as to whether or not the pair of corresponding points on each of the images are spaced at least a predetermined distance apart from each other. If not, the corresponding points are specified again. After the corresponding points are determined, the coordinates of the corresponding points are stored. The coordinates of an objective point at which a colorimetric value is to be computed is computed based on the corresponding points. Next, a colorimetric value on the coordinates is measured.

Abstract: Adjustment object color space containing movement source partial color space including a color of an object of conversion processing and movement destination partial color space including a color in which the conversion processing is performed so as to inscribe the spaces is handled as a conversion object region. The inside of the conversion object region is moved toward a target color so that coordinates of an adjustment object overlaps with coordinates of a point after movement and the boundary of a movement region moves little or does not move at all. As a result of this, a phenomenon such as a color jump or gradation inversion occurs little in the boundary portion to the outside of an adjustment object region. Therefore, maintenance of gradation continuity of an image of a color adjustment object and prevention of color inversion can be combined to make partial color adjustment.

Abstract: Sets of pixel data obtained by dividing entered image data into a predetermined number of items of data are stored in storage means in a predetermined order, and conversion processing is executed for obtaining individual items of pixel data of an output image by applying predetermined processing to the stored pixel data. When the conversion processing is executed, it is determined whether a set of pixel data to be stored in the storage means next is used in conversion processing, and control is carried out in such a manner that a set of pixel data determined not to be used in conversion processing will not be stored in the storage means. As a result, processing for storing unnecessary data not used in conversion processing can be eliminated, thereby making it possible to raise the overall speed of image processing.

Abstract: An object of the present invention is to provide an image communication apparatus which can improve the noise-reducing effect when a ringing tone has been set to non-ringing or when an operation mode at a start time of recording is for recording at a fax receive time, and which can prevent a recording speed from lowering at a time when a ringing tone has been set to ringing, at a time of copying or at a similar time. There is provided an image communication apparatus which performs recording in a silent mode more silently than in a regular mode when a ringing tone has been set to non-ringing or when an operation mode at a start time of recording is for recording at a fax receive time, and performs recording in a regular mode at a time when a ringing tone has been set to ringing, at a time of copying or at a similar time.
