An information processing apparatus includes a detector, a receiver, and an image processor. The detector is configured to detect a punch hole candidate partial image having a punch hole accuracy indicating whether the punch hole candidate partial image is a punch hole image is less than a first threshold value and equal to or greater than a second threshold value smaller than the first threshold value, from plural partial images constituting a read image of a document. The receiver is configured to display the punch hole candidate partial image, and receive an instruction from a user as to whether to perform image processing on the punch hole candidate partial image. The image processor is configured to perform the image processing on the punch hole candidate partial image when the receiver receives an instruction to perform the image processing on the punch hole candidate partial image.

A reading method guidance apparatus includes a receiving unit, an acquisition unit, and a guidance unit. The receiving unit receives a document size that is a size of a document as a reading target. The acquisition unit acquires an image of at least a partial area in the document. The guidance unit provides an operator with guidance about a reading procedure when the document is read by a first reading apparatus in plural batches, using a feature amount obtained from the acquired image, the received document size, and a readable size that is a size of an area readable by the first reading apparatus.

A document size detecting apparatus includes a first acquisition unit, a second acquisition unit, and a detector. The first acquisition unit acquires a first image that is an image of an entire document as a reading target. The second acquisition unit acquires a second image that is an image of a part of the document read by a first reading apparatus. The detector detects a size of the document using a result of a matching process between the first image and the second image and a read size that is a size of the second image read by the first reading apparatus.

According to an aspect of the invention, an image processing apparatus includes a generating unit, a calculating unit, a receiving unit, and a changing unit. The generating unit generates a plurality of histograms of images with respect to each color based on an input image. The calculating unit calculates a plurality of first image densities of the images from the histograms. The receiving unit receives a content of image quality adjustment performed on the input image. The changing unit changes one of the histograms based on the content of the image quality adjustment. The one of the histogram corresponds to one of the images on which the image quality adjustment is performed. The calculating unit calculates a second image density corresponding to the one the images based on the one of the histogram changed by the changing unit.

An image processing apparatus includes the following elements. A characteristic value calculator calculates characteristic values of a preset area set around a pixel of interest. A trapping determining unit determines, for each color plane of an N-valued image, on the basis of the calculated characteristic values, whether the pixel of interest is to be subjected to trapping processing. A pixel value calculator sets, for each color plane, a position of a reference pixel in a reference area, and calculates a pixel value for changing the pixel value of the pixel of interest on the basis of a pixel value of each color plane at the position of the reference pixel. A pixel-of-interest value changing unit changes the pixel value of the pixel of interest into the calculated pixel value when the trapping determining unit determines that the pixel of interest is to be subjected to trapping processing.

An image processing apparatus includes a storage unit, a judgment unit and a conversion unit. The storage unit stores a reference color characteristic. The judgment unit judges as to whether or not a difference between an input color characteristic that is a color characteristic of input image data and the reference color characteristic is equal to or less than a predetermined threshold value. The conversion unit converts the input image data into a color characteristic that can be reproduced by an image reproducing apparatus, based on the reference color characteristic if the difference is equal to or less than the predetermined threshold value.
