Abstract: In an image reading apparatus, based on image data obtained by reading a white image, detection is performed of an abnormal pixel based on a foreign substance adhering to a reading position of an original and data indicating a position of the abnormal pixel is outputted, then image data obtained by reading an original is corrected based on that data, and detection of the abnormal pixel is carried out immediately prior to reading of a first original, and a correction process based on data indicating a position of the abnormal pixel is carried out on image data obtained by reading a second original following on from the first original.

Abstract: An information input device which enable even a user incapable of seeing an operation panel to identify the respective locations of keys on the operation panel and functions assigned to the keys, thereby enhancing operability of the device. The information input device is provided with a touch panel for inputting coordinate information based on a location thereon touched by a user. A pressure sensor detects the location on the touch panel touched by the user. A CPU determines whether or not there is a key assigned to the location detected by the pressure sensor. When it is determined that there is a key assigned to the location, a vibration generator vibrates the touch panel in a vibration pattern associated with the key. Further, when it is determined that there is a key assigned to the location, a voice output section outputs a voice associated with the key.

Abstract: An image forming apparatus capable of communicating with an information processing apparatus receives identification information from the information processing apparatus, which has generated settings relating to a copy job to be executed in the image forming apparatus. The identification information indicates the settings of the copy job. The image forming apparatus displays multiple items of received identification information, notifies the information processing apparatus of identification information selected by a user, receives setting values of the copy job corresponding to the selected identification information, the setting values being transmitted from the information processing apparatus in response to the notification, determines whether the image forming apparatus is capable of executing the copy job based upon the setting values, and outputs the result of the determination.

Abstract: An interface circuit between a first device capable of being supplied with a first power and a second device capable of being supplied with a second power independent of the first power includes a first reference voltage generation unit configured to generate a first reference voltage from the first power, a second reference voltage generation unit configured to generate a second reference voltage from the second power, and a switching unit configured to switch to input respective different ones of the first and the second reference voltages to the first and the second devices. In this configuration, the memory controller can be separately powered off while electric power is being supplied to the memory which is connected to the memory controller via a bus.

Abstract: An image processing apparatus for processing image data having attribute information for every pixel of the image data, includes a combining unit that combines component image data, which corresponds to each of a plurality of component images, into composite image data that corresponds to a single composite image, and an attribute appending unit that appends identification information, which indicates the component image data to which each pixel belongs, as attribute information of pixels of the composite image data. In addition, a processing unit applies common image processing to pixels having identical values as the identification information based on the attribute information.

Abstract: There is provided a copying apparatus and a method of controlling the same which are capable of performing a proper search for an original file even when the image quality of the original is heavily degraded such that the additional information cannot be read or is not correctly recognized, to thereby obtain a copy without degradation in image quality regardless of the condition of the original. Additional information is read from an image signal from an original inputted by a scanner unit. A search is carried out for an original file corresponding to the original based on the read additional information. A printer outputs a copy of the original using the original file found as a result of the search. The additional information is displayed and edited. The search is controlled using the edited additional information.

Abstract: In an image output apparatus which performs printing based on transferred data, when bus reset occurs during isochronous data transfer through a serial bus, the data transfer is suspended and a print error is caused. Therefore, when bus reset occurs during image data transfer through the serial bus, transferring and outputting of image data is performed again, and stapling is performed for proper stapling. Similarly, when bus reset occurs, transferring and outputting of image data is suspended, the printouts whose printing has been suspended are discharged to a dedicated bin provided for erroneous printouts, and transferring and outputting of the image data is performed again. Accordingly, an erroneous printout caused by bus reset is not intermingled with proper printouts on the same bin.
