摘要： 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.

摘要： 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.

摘要： An information loss determiner in an image processing device determines whether character collapse has occurred in a simple binarized image. If character collapse has not occurred in the simple binarized image, an image processing determiner selects simple binarization processing as the image processing method of output image data. If character collapse has occurred in the simple binarized image, the process proceeds to photograph area size determination. If the ratio of a photograph area size is less than or equal to a predetermined value, the information loss determiner determines that character collapse has occurred in a posterization processed image. If character collapse has occurred in the posterization processed image, the image processing determiner selects grayscale processing. If character collapse has not occurred in the posterization processed image, the image processing determiner selects posterization processing.

摘要： A system includes an image processing device connected to a transmission and reception device that communicates with an external device, and a terminal device connected to a display device. The image processing device includes an evaluation value calculation processor that calculates, for each of two or more types of output modes, an evaluation value of output image data when image data is output in the output mode, and an evaluation information transmitter that transmits evaluation information including information based on the evaluation value for each of the output modes, to the terminal device, via the transmission and reception device. The terminal device includes a display controller that performs control of displaying, for each of the output modes, the information based on the evaluation value corresponding to the output mode, on the display device, if the evaluation information is received.
