The present invention enables improvement in user convenience while reducing security degradation. To accomplish this, an information processing apparatus includes a display unit that displays an operation screen; an acceptance unit that accepts input from a user; a display control unit that controls display so as not to change the operation screen to a predetermined state when a predetermined time elapses without accepting input from the user by the acceptance unit; and an acquisition unit that acquires biological information of the user, wherein the display control unit does not change the operation screen to the predetermined state even if the predetermined time elapses without accepting input from the user by the acceptance unit if, within the predetermined time, the acquisition unit acquires biological information of the last user from whom input was accepted by the acceptance unit before the predetermined time started to be counted.

Information processing apparatus, control method therefor, and program

The present invention provides a multifunction system and a control method thereof which enables output of conference materials of appropriate content at an appropriate timing and in an appropriate location, without making the conference organizer worry about the needs and rank of conference attendees. To accomplish this, the multifunction system of the present invention comprises a server which manages attribute information of members, a server which manages reservation information of conferences, and a print server which manages output of conference materials. The print server acquires attribute information corresponding to attendees of the conference included in the reservation information from the member management server, and outputs the conference material for each attendee based on the attribute information of each.

Multifunction system and its manufacturing method

One or more character strings are extracted from within an inputted image. The extracted character strings are retrieved to find one or more identical character strings. A determination is then made as to whether or not the identical character strings are laid out regularly, with processing performed on the inputted image depending on the findings of the determination.

Image processing apparatus that extracts character strings from a image that has had a light color removed, and control method thereof

When the data is divided into blocks each having a set block size, and image data includes an object which extends over a plurality of blocks, the object is divided based on object information associated with the object. The object information of the divided object is re-set based on the object information associated with the object divided into blocks. Block vector image data are generated using the object having the re-set object information.

Image processing apparatus and control method thereof, and program

The invention is to achieve, in a multifunction multifunction system applicable to a copying apparatus or a printer, automatic switching of an image processing method and a compression/expansion method for each compressed packet image (tile image). this object is achieved by a system including a storage unit for storing image data read by an image reading unit; a packet data generation unit for dividing the image data into plural tiles of a predetermined size and generating, for each tile, packet data composed of a header portion and an image data portion, the header portion including identification information for determining an image processing method for an image data portion corresponding to the header portion; a transfer unit for transferring the packet data corresponding to each tile from the storage unit; and an image processing unit for entering the packet data transferred from the transfer unit and utilizing an image processing method corresponding to the identification information described in the header portion of the packet data to apply an image processing to the corresponding image data portion.

Multifunction system, image processing method, computer program and memory medium

An original is allowed to pass on an exposing glass along a conveying path, thereby exposing and scanning a front surface of the original and reading an image by a CCD. A back surface of the original is subsequently fed to the exposing glass along a conveying path and is allowed to pass on the exposing glass, thereby exposing and scanning the back surface of the original. The image data read by the CCD is stored into an image buffer. The order of address columns to read out the image data on the front surface and the order of address columns to read out the image data of the back surface are made opposite. Thus, a copying apparatus which can efficiently expose and scan both of the front and back surfaces of a both-side original is provided.

Copying apparatus capable of exposing and scanning both-side original

An image processing apparatus includes a processing unit for processing an image signal into which an original document, after being exposed to light, is photoelectrically converted, a compression module for compressing image information processed through the processing unit, a memory for storing image data compressed by the compression module, a control unit for setting a diversity of image processing modes, and a predicting module for predicting an image compression rate used by the compression module. The predicting module predicts the image compression rate of an image after being processed according to the image processing mode set by the control unit.

Image processing apparatus and method for predicting a compression rate

An original document reading apparatus includes a first control portion for performing a first control wherein documents are transported at a first document interval in the event that a detected occupying capacity is less than a detected unused capacity. The first control portion also performs a second control wherein documents are transported at a second document interval which is greater than the first document interval in the event that the detected occupying capacity exceeds the detected unused capacity. A second control portion continuously activates an exposure portion under the first control, and intermittently activates the exposure portion under the second control.
