Translation device, translation method, and storage medium

A translation requesting device has a first replacing unit, a translating unit and a second replacing unit. The first replacing unit replaces an original phrase to a substitute phrase. The translating unit translates the substitute phrase. The second replacing unit replaces the original phrase to a translation phrase based on the translated substitute phrase. The substitute phrase is decided to maintain semantic properties of the original phrase.

An image reading apparatus has a scan quality parameter extraction part, a scan quality evaluation part and a notification part. The scan quality parameter extraction part extracts scan quality parameters representing the quality of a scanned image from image data based on a scan error detection algorithm. The scan quality evaluation part determines whether a scan error occurs, based on the scan error detection algorithm and the scan quality parameters. Also, the notification part notifies a result determined by the scan quality evaluation part to a user.

Image reading apparatus

An image processing apparatus sequentially reduces a document, while changing the reduction factor step-by-step. Next, the image processing apparatus refers to the characters that constitute the document that has been reduced with the respective reduction factors, and specifies a reduction factor at which blank regions surrounded by line portions that express each character do not disappear. When an appropriate reduction factor is specified, the image processing apparatus specifies a resolution of the characters for that reduction factor, and converts the resolution of the document data to that specified resolution. Then, the image processing apparatus performs various processing for the document data whose resolution has been converted. Thus the resolution of document data is converted such that the document is reduced with a reduction factor suitable for computer processing.

Adjustment object color space containing movement source partial color space including a color of an object of conversion processing and movement destination partial color space including a color in which the conversion processing is performed so as to inscribe the spaces is handled as a conversion object region. The inside of the conversion object region is moved toward a target color so that coordinates of an adjustment object overlaps with coordinates of a point after movement and the boundary of a movement region moves little or does not move at all. As a result of this, a phenomenon such as a color jump or gradation inversion occurs little in the boundary portion to the outside of an adjustment object region. Therefore, maintenance of gradation continuity of an image of a color adjustment object and prevention of color inversion can be combined to make partial color adjustment.

An image processing device can reproduce the original color of an electronic document on an output device faithfully and can simulate the appearance of color of a recorded product on a display device accurately. Color temperature information of an electronic document is recognized by an electronic document color temperature information recognition unit and delivered to a first color correction conversion unit. The first color correction conversion unit carries out color conversion based on the color temperature information of the electronic document so that a recorded product output from an output device assumes substantially the same color as the electronic document when it is observed under an illumination light source having a color temperature indicated by the color temperature information of the electronic document. An image is formed by the output device based on the color converted image signal to output the recorded product.

The invention provides a color processing method that is capable of improving the color reproduction accuracy by calculating an adequate amount of black component (referred to as K) with consideration of the coverage restriction when a four-color signal including the black component is generated from a color signal of a input color space. By a YMCK modeling unit, adjustment K calculation unit, restriction K calculation unit and optimal K modeling unit, modeling is performed between the representative color signal and the corresponding optimal K by use of plural color signals that belong to the partial color space, namely the color gamut that is reproducible with three colors and by use of plural color signals that belong to the area on the curved plane that is reproducible with four colors including the black component as the representative color signal. An optimal K determining unit predicts an optimal K corresponding to the input color signal in the input color space based on the model. Furthermore, a YMCK color signal calculation unit predicts three colors except the black component from the input color signal and the predicted optimal K. As described hereinabove, a four-color signal including K is generated.
