摘要:
An image input device identifies what part of the optical input system needs cleaning when there is dust or other foreign matter in the optical input system. This image input device has an image noise position detector for capturing image data from a scanner, and detecting the main scanning address of noise information corresponding to image noise present in the image data; a focus calculator for calculating focus information around the main scanning address detected by the image noise position detector; focus information storage for storing focus information for each subscanning line; and a foreign matter position determining circuit for determining the location of foreign matter on the scanner based on the focus information stored in the focus information storage.

An image forming apparatus automatically identifying top and bottom of document image based on characteristics with regard to shapes or positions of data, etc. recorded on document. Distribution states of pixel cumulative values in main scanning direction and sub scanning direction of image signals provided by scanning the document, are analyzed and top and bottom of the document image is identified from the result of analysis. Further, it is possible to identify the top and bottom of the document image by analyzing the distribution states the pixel cumulative values in the main scanning direction and the sub scanning direction of the image signals and identifying letter series regions and line segment regions displaced therefrom. In addition thereto, it is possible to automatically identify the top and bottom of the document image based on distribution states in the main scanning direction and the sub scanning direction of specific signs included in the image signals provided by scanning the document or distribution states of pixel cumulative values of specific image regions including the specific signs.
摘要:
A film scanner for generating output image data by applying a correction process referring to a predetermined parameter to the read out image data generated by scanning an original is connected to a digital color printer. When an adjustment mode is specified in the film scanner, the reference output image data generated based on scanning a reference original by a printer is fed to the film scanner to be set as the target data. Based on read out image data generated by scanning a reference original having characteristics identical to those of a reference original, a parameter is calculated to be set for a correction process so that output image data matching the reference data is generated.

Disclosed is an image processing apparatus by which a first image corresponding to first image information and a second image corresponding to second image information are superimposed one on the top of the other, the apparatus comprising a scanning device for scanning a document line by line to output the first image information; a composing device for composing the first and second image information so that the first and second images are superimposed one on the top of the other; a detecting device for detecting changes of the scanning speed in a direction perpendicular to the lines; and a controlling device for so controlling the composing device that the relative position of the second and first images in the direction are adjusted line by line in accordance with the results detected.
摘要:
An image forming apparatus maintaining the fixing temperature at a fixed level, by detecting the surface temperature of a heating roller provided internally with a heater in a fixing unit, and by controlling an on-time which starts upon the surface temperature reaching a predetermined temperature and ends when the heater is switched on and an off-time which starts upon the surface temperature reaching the predetermined temperature and ends when the heater is switched off. The on-time and off-time data are stored in a memory corresponding to use conditions such as ambient temperature and the type of paper to be used. Initially, an image fixing operation is executed in accordance with the data prestored in the memory, and transition of the surface temperature of the heating roller is detected which results from the image fixing operation. Data concerning new on-time and off-time are calculated on the basis of the detection result, and the calculation result is used as feedback for a next image fixing operation.
摘要:
A first terminal device indicates a file based on a first gesture on a touch panel, and upon receipt of a search instruction by a second gesture on the touch panel, transmits search information including the indicated file and user information to an image processing device. The image processing device stores the search information. A second terminal device obtains search information from the image processing device, executes a search operation using the search information, and transmits information that identifies retrieved data to the first terminal device as a search result.

An image processing apparatus includes an operation panel as a touch panel and a CPU for performing processing based on a gesture thereon. The CPU includes a determination unit for determining a detail of processing corresponding to the gesture. When the detail of processing corresponding to the gesture includes a first detail of processing as processing on a file and a second detail of processing as processing on a displayed image and when the file targeted for the processing is stored in a storage device, the determination unit determines the detail of processing as the first detail of processing.
