An image forming apparatus includes an image forming section, a measuring section, a generating section, and a predicting section. The image forming section forms an image on a sheet. The measuring section measures sound or vibration in the image forming section to obtain a measured result. The generating section generates frequency data through a frequency analysis of the measured result. The predicting section predicts a malfunction to occur of the image forming section based on the frequency data.

Image forming apparatus and image forming method

An image forming apparatus includes an image forming section and a controller. The image forming section forms an image on a first sheet or a second sheet. The controller controls the image forming section. The first sheet is a blank sheet. The second sheet is a reused sheet. The controller refers to reference images each belonging to any of a plurality of categories to determine whether or not the image belongs to any of the categories. The controller directs the image forming section to form the image on the second sheet when determining that the image does not belong to any of the categories. The controller directs the image forming section to form the image on the first sheet and stores the image as a reference image when determining that the image belongs to any of the categories.

A binary image generation portion binarizes a scanned image and generates a binary image. A specific character position detection portion (a) specifies rectangles that circumscribe a plurality of characters, respectively, in the binary image, (b) detects a plurality of specific characters having longitudinal lines or transverse lines at centers of the specified circumscribing rectangles, and (c) detects, as positions of the plurality of specific characters, center positions of the longitudinal lines or the transverse lines, within a predetermined range, to be detected, in a main scanning direction or a sub-scanning direction. A skew angle specifying portion specifies an alignment direction in which the plurality of specific characters are aligned, based on the positions of the plurality of specific characters detected in the range to be detected, and specifies a skew angle of a document image in the scanned image, based on the specified alignment direction.

Image processing apparatus

An image reducing unit performs a reduction process for each reduction target area in one of a primary scanning direction and a secondary scanning direction, and subsequently performs a reduction process for each reduction target area in the other of the primary scanning direction and the secondary scanning direction. A binarizing unit binarizes pixel values of pixels in the reduction target area. A characteristic value identifying unit identifies a characteristic value on the basis of a pattern of the binarized pixel values and integrates the characteristic value. When the integrated value of the characteristic value exceeds a threshold value before the image reduction unit finishes the reduction processes, a control unit terminates the reduction process, changes the reduction ratio so as to increase a size of a reduced image, and causes the image reducing unit to perform the reduction process with the changed reduction ratio again.

For calculating a zooming ratio for a scanned image of an original document that includes a handwritten object, in each of the primary and the secondary scanning direction, the zooming ratio calculating unit generates projection images of black objects in an original image of the original document and the scanned image, identifies the smallest and largest pixel positions in the projection image of the original image, identifies the corresponding smallest and largest pixel positions in the projection image of the scanned image, and calculates the zooming ratio on the basis of a two distances between the smallest and the largest pixel positions of the original image and the scanned image. After zooming the scanned image by the zooming ratio, an image of the handwritten object is extracted on the basis of the zoomed scanned image and the original image.

A binarizing section generates binary image data representing a binary image from raster image data representing a raster image. A white-pixel ratio determining section determines, based on the binary image data, a white pixel ratio for each line of the binary image and a position of each of lines having a white pixel ratio equal to or greater than a predetermined first threshold among the lines of the binary image, and also determines a white pixel ratio for an entirety of the binary image. An image-type determining section determines that the raster image is a photographic image when the white pixel ratio of the entirety of the binary image is equal to or less than a predetermined second threshold, and that the raster image includes a text image when the lines having a white pixel ratio equal to or greater than the first threshold appear cyclically in the binary image.

Image processing device

An image processing apparatus includes a local maximum point identifying unit, a distribution deriving unit, and a binding position identifying unit. The local maximum point identifying unit is configured to identify positions of local maximum points of densities along a first scanning direction in an input image of a book. The distribution deriving unit is configured to derive a distribution in the first scanning direction of the number of the local maximum point obtained along a second scanning direction perpendicular to the first scanning direction. The binding position identifying unit is configured to identify a binding position in the input image of the book on the basis of a position of a peak in the distribution.

The width specifying part specifies a width between both ends of an input image of a book about each line of the input image. The parameter value specifying part specifies a value of a density correcting parameter corresponding to the width specified by the width specifying part. The density correcting part corrects density of each line on the basis of the value of the density correcting parameter specified by the parameter value specifying part.

An image forming apparatus has a printing unit for executing a single-sided print job and a double-sided print job. A storage unit stores print target data as backing sheet image data when a single-sided print job is executed. An image reading unit reads images on both sides of a document that is subjected to image processing. A backing sheet judgment unit judges whether there is an image that matches a backing sheet image among the images on both sides of the document by comparing the document image data read by the image reading unit with the backing sheet image data stored in the storage unit. An exclusion processing unit performs processing to exclude from the image processing targets an image judged by the backing sheet judgment unit to match the backing sheet image among the images on both sides of the document read by the image reading unit.
