An image processing apparatus includes: a memory; an obtaining unit that obtains image data representing an image including concatenated pixels; an isolating unit that isolates a rendering element, the rendering element being an image surrounded by border lines of a color in an image represented by the image data; and a classifying unit that, in a case where a plurality of rendering elements has been isolated by the isolating unit, and in a case where color difference between two of the plural rendering elements or the distance between the two rendering elements is less than a threshold, classifies the two rendering elements into the same group, associates pieces of image data that represent rendering elements belonging to the same group with one another, and stores the pieces of image data in the memory.

Image processing apparatus including an obtaining unit, an isolating unit, a classifying unit, information processing apparatus, and image reading apparatus

A character recognition device includes: an acquiring unit that acquires image data describing pixel values representing colors of pixels constituting an image; a binarizing unit that binarizes the pixel values; an extracting unit that extracts boundaries of colors in the image; a delimiting unit that delimits plural image areas in the image; a specifying unit that specifies, with regard to first image areas arranged according to a predetermined rule, pixels binarized by the binarizing unit, as a subject for character recognition, and specifies, with regard to second image areas not arranged according to the predetermined rule, pixels of areas surrounded by boundaries extracted by the extracting unit, as a subject for character recognition; and a character recognition unit that recognizes characters represented by the pixels specified by the specifying unit as a subject for character recognition.

Character recognition device, image-reading device, computer readable medium, and character recognition method

An image processing apparatus includes: a first determination unit that determines whether each of an image regions is for a vector image; a color number counting unit that counts the number of colors in the pixels of high-resolution image data; a frequency counting unit that counts a number of times where the difference between the colors of each of the pixels in the high-resolution image data and the colors of at least one pixel located around each of those pixels is greater than or equal to a threshold; a second determination unit that determines that the image region is not an image region for a vector image; and a generation unit that generates image data in which a process for rendering images in the image regions determined by the first determination unit to be image regions for vector images is defined by numerical values or numerical formulas.

Image processing apparatus and image forming apparatus

An image reading apparatus including: a paper supply section; a transporting path for transporting a document supplied from the paper supply section; a first sensor which reads an image on a first surface of the document from one side of the transporting path; a second sensor which reads an image on a second surface of the document from the other side of the transporting path; and an image processing section which is constituted so as to correspond to a first reading mode in which two sides of the document are read using the first sensor plural times, and a second reading mode in which two sides of the document are read using the first sensor and the second sensor, and which makes a registration position and direction of an output image in both the first and second reading mode the same.

Image reading apparatus, image processing system and registration method in two-side image reading

The invention provides an image reading apparatus includes a feeder that feeds a sheet, a transfer path on which the sheet fed by the feeder is transferred, a first reading unit that captures a first image on a first face of the sheet from one side of the transfer path to obtain first image data, a second reading unit that captures a second image on a second face of the sheet from the other side of the transfer path to obtain second image data, and a correction unit that substantially equalizes image density of the first image data and that of the second image data in a case where the first image and the second image are captured at a single transfer of the sheet through the transfer path.

Image reading apparatus for correcting images on both sides of a document sheet

An image reading apparatus includes: a light source that irradiates a document; a sensor that receives reflection light reflected from the document; a reference member that is read by the sensor; and an abnormal site detection unit that detects, using first reading data acquired by reading the reference member according to a first reading condition set to the light source or the sensor and second reading data acquired by reading the reference member according to a second reading condition, which is different from the first reading condition, set to the light source or the sensor, abnormal sites in the first reading data or the second reading data.
