An image processing apparatus includes: an input device that inputs a document image; and a controller, wherein the controller removes a streak from the image by a first method, removes a streak from the image by a second method that differs from the first method, and executes crop processing on the image from which the streaks have been removed.

Image processing apparatus, control method, and non-transitory computer-readable medium

The multifunction peripheral of the present invention includes an ADF document crop function. According to this ADF document crop function, front side image shaping processing for cutting out a front side document image corresponding to the image on the front side of a document, from a front side read image of the document and for correcting the tilt of the front side document image is performed. Then, on the basis of shaping information in the front side image shaping processing, back side image shaping processing for cutting out a back side document image from a back side read image of the document and for correcting the tilt of the back side document image is performed.

Device for reading images on both sides of a document in parallel, recording medium, and controlling method thereof

An image processing apparatus of the present invention uses a spatial filter section or an enlarging/reducing section to perform a blur process on image processing data to be supplied to an image display device, thus allowing the image display device to display a preview without deterioration in image quality.

Image processing apparatus, image forming apparatus, image processing method, and computer-readable storage medium containing image processing program

An image processing apparatus of the present invention includes: a blank document determination section determining whether or not input image data is image data of a blank document, regardless of a process mode set for setting a process with respect to the input image data; a storage device storing the input image data in association with a determination result made by the blank document determination section; and a control section (i) reading out the input image data from the storage device and (ii) excluding the input image data determined as image data of a blank document by the blank document determination section, from images to be displayed by the image display device, when the image display device carries out a preview display of the input image data. This configuration makes it possible to carry out a preview display in which a blank document (blank page document) is skipped, without reading the document again.

A two color process section included in the image processing apparatus includes a luminance and chroma calculation section, an image-data determination section, and an output-color generation section. The luminance and chroma calculation section calculates a luminance value and a chroma value based on input image data. The image-data determination section determines the input image data, the chroma value of which is equal to or greater than a predetermined threshold, as first input image data constituting a chromatic color in a two-color image and determines the input image data, the chroma value of which is less than the threshold, as second input image data constituting an achromatic color in the two-color image. The output-color generation section generates image data of CMY from the first input image data based on the chroma value and the luminance value and generates image data of CMY from the second input image data based on the luminance value.

Image processing apparatus, image forming apparatus, image processing method, and computer-readable recording medium on which image processing program is recorded

An image processing apparatus includes a two color process section and a color material usage estimation and calculation section. The two color process section generates, based on input image data of RGB inputted by reading an original document, image data of CMY for outputting a two-color image. The color material usage estimation and calculation section calculates, based on the image data of CMY generated by the two color process section, a usage of color materials used when the two-color image is outputted and generates information concerning the usage of color materials from a result of the calculation. The color material usage estimation and calculation section outputs the generated information concerning the usage of color materials to an image display device.

Color material usage estimating image processing apparatus, image forming apparatus, image processing method, and computer-readable recording medium on which image processing program is recorded

A display control device controls an image display device capable of displaying a preview of an output image that is to be subjected to an output process, before the output image is subjected to the output process. The display control device refers to a storage section in which specific information specifying an image process which a user cannot recognize from a previewed output image is stored, and selects an image process specified by the specific information out of image processes to be carried out on the output image. Further, the display control device causes the image display device to display a setting confirmation image showing a content of the selected image process. This allows a user to correctly understand the content of an image process to be carried out on the output image and the image quality of the output image subjected to the output process.
