Abstract: An image determining apparatus of the present invention includes an image type determining section (81) which determines whether an image is a scanned image or a captured image; and a compact PDF file generation determining section (82) which (a) extracts (i) a feature regarding a resolution from the scanned image or (ii) a feature regarding a blur from the captured image and (b) determines, on the basis of the extracted feature, whether or not the image is suitable for the conversion.

Abstract: An image processing device includes an image reader that reads an image, a first determiner that determines whether character crushing occurs when the image is binarized, a second determiner that determines a rate of a photographic region in the image, and a controller that performs conversion into monochrome N-gradation image data based on determination results of the first and second determiners.

Abstract: A multifunction peripheral includes a color number conversion determiner. The color number conversion determiner determines whether it is appropriate to perform either an index color process or a full-color process based on a color distribution degree, which is a distribution degree of pixel values of the respective sets of pixel data included in input image data, a photograph area ratio, which is a ratio of photograph area pixel data forming a photograph area to the pixel data, and a color uniformity area ratio, which is a ratio of white base area pixel data forming a white base area to the pixel data.

Abstract: An image processing apparatus processes input image data and generates output image data. The image processing apparatus includes a feature-value calculating unit, an output-gradation-number setting unit, and an image processor. The feature-value calculating unit calculates a feature value from the input image data. The output-gradation-number setting unit sets, as the number of output gradations, any one gradation number of candidates for the number of output gradations based on the feature value calculated by the feature-value calculating unit. The image processor processes the input image data and generates the output image data having the number of output gradations which is set by the output-gradation-number setting unit.
