摘要： 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.

摘要： 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.

摘要： 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.
