摘要:
In order to prevent the appearance of gaps in fine lines when image data undergoes resolution conversion, the image processing apparatus includes an image reading unit that inputs image data, a fine line detection unit 113 that detects fine lines from the image data, a resolution conversion unit 111 that converts the image data to a prescribed resolution, and a fine line restoration unit 114 that restores fine lines in the image data that has undergone resolution conversion.

An image processing apparatus reducing image noise caused at a device which has a stationary reading portion such as a CCD sensor and reads an image of a document by moving the document is structured as follows: the image processing apparatus determines whether full color image data read by the reading portion is out of a predetermined color space; it uses shift resisters to determine that the image data out of the predetermined color space continues in a sub scanning direction; and thus it detects a line-shaped dirt image caused by dirt or the like at the reading portion, and corrects the dirt image.

A multibeam scanning optical apparatus incluses a controller which specifies laser diodes which are emitting light normally and arranged in a continuous row, a memory having a plurality of area in which image data are stored, a write-in controller which causes image data for each line to be written into only areas of memory corresponding to the specified laser diodes when any of the laser diodes suffers a failure, a read-out controller which causes the image data for each line to be read out simultaneously from the areas of memory corresponding to the specified laser diodes and a driver which performs light emission control only with respect to the specified laser diodes.

A two-beam scanning optical apparatus includes a first beam generating device, a second beam generating device, a judging unit which judges whether the second beam generating device is operating normally or not, a raster signal processing unit which outputs a raster signal each time if the judging unit judges that the second beam generating device is operable, and which outputs a raster signal every other time if the judging unit judges that the second beam generating device is not operable and a control unit which performs image formation by using the first beam generating device and the second beam generating device based on the raster signal output every other time, and which performs image formation by using only the first beam generating device based on the raster signal output each time.
摘要:
An image forming apparatus accepts setting related to scanning of documents and setting of a destination of image-related information including thumbnail images, and stores image data obtained by scanning. Further, the image forming apparatus produces the image-related information including the thumbnail images from the image data, and sends it to a personal computer being the set destination. The personal computer displays the thumbnail images, and instruction of an output form of the image data is provided to the image forming apparatus by using the thumbnail image. The image forming apparatus outputs the stored image data in the output form instructed by the personal computer.

The printer having the mail-bin feature, at a time when the output for all the print jobs addressed to the same user, an output completion notice is transmitted to the particular user. When, in such a state that the previously discharged printed matter for a certain user (user D) still remains in any bin (bin 1), an attempt is made to process a print job for another user (user A) which designates the same bin as the discharge destination, an output completion notice is transmitted to the user (user D) the printed matter for whom still remains in the same bin before the print job is processed and the output completion notice is transmitted to the other user (user A).
