Abstract: An image processing apparatus includes an image inputting unit configured to input image data of an original image, an area specifying unit configured to specify a predetermined area in the input original image as a specified area, a partial image creating unit configured to create a partial image by extracting an image section corresponding to the specified area specified by the area specifying unit, and a miniature image creating unit configured to reduce the partial image and to create a miniature image. According to the present invention, a thumbnail appropriately indicating the content and the feature of an original image are readily and quickly created even if the original image includes a complex image section.

Abstract: One or more rectangular regions including image objects are extracted from input document image. The input document image is reduced by a desired scale factor, and the extracted rectangular regions are varied in scale by scale factors greater than the desired scale factor. The input document image varied in scale by the desired scale factor and the rectangular region images varied in scale are synthesized and outputted.

Abstract: A feature amount calculating unit calculates feature amounts of an image on the basis of input image information provided from an image reading apparatus. An image mode deciding unit decides image mode of output image information provided from the apparatus on the basis of the feature amounts provided from the feature amount calculating unit. A reading mode setting unit sets a reading mode of the image reading apparatus on the basis of the image mode decided by the image mode deciding unit.

Abstract: A trapping means judges that the gradated region is dark if compared with the uniform region and expands the uniform region to cause colors to overlap when the density average value Da of the gradated region is greater than the density value Du of the uniform region but judges that the gradated region is light if compared with the uniform region and expands the gradated region when the density average value Da of the gradated region is smaller than the density value Du of the uniform region.

Abstract: Plural line sensors are arranged parallel to each other in a predetermined order and with a predetermined interval, and they read different lines on a manuscript respectively. A delay module outputs an image signal output from at least one of the plural line sensors with a delay for a number of lines according to a number of pixels which corresponds to shifts of reading positions of the plural line sensors. An ahead-reading signal acquiring module outputs the image signal acquired from at least one line sensor other than a last stage line sensor of the plural line sensors as an ahead-reading signal. The image processing device outputs the image signal wherein the shifts of the reading positions of the plural line sensors are corrected by the delay module, and outputs the ahead-reading signal acquired by the ahead-reading signal acquiring module.
