Abstract: When a reduction instruction is given to characters contained in a character region displayed in a wrapped-display mode, the display apparatus of the present invention determines whether or not the width of the reduction-instructed character region to which the reduction instruction has been made is equal to or less than the width of the screen. When the display apparatus determines that the width of the reduction-instructed character region is equal to or less than the width of the screen, the display apparatus controls to switch the wrapped-display mode to the partial region display mode.

Abstract: In display apparatuses each including a touch UI, some of them correct or suppress the direction of display position shift in swipe operation. It is, however, inconvenient that sometimes the correction or suppression is performed at an undesired timing. The display position shift is suppressed depending on an attribute of a displayed object.

Abstract: An image processing apparatus prints a processing instruction sheet for instructing to perform processing on a document to be processed. The processing instruction sheet is printed only when a processing region displayed by a display unit and a content of processing to be performed thereon are determine to be the same as those instructed by a user.

Abstract: An image forming apparatus, configured to extract additional information added to an original document and perform a processing according to a result of the extraction, inputs image data obtained by causing a scanner to read an image of the original document, converts color component of the input image data into a color component different from the color component of the additional information, and causes a printer to print image data having the converted color component as a document to which a user can add additional information.

Abstract: For reducing jaggies in second image data based on first image data, the second image data obtained by performing digital halftoning on each image signal of the first image data, and attribute data indicating the attribute of each pixel in the first image data, a determination signal indicating whether or not to perform smoothing processing is output based on the first image data, edge correction data for the smoothing processing is generated from the first image data, and whether or not to perform edge correction processing that uses the edge correction data is selected according to the determination signal and the attribute data. Moreover, the second image data and the edge correction data are compared for each image signal so as to output either one thereof according to the comparison result.

According to the halftoning method, whether the less-than-one-pixel-basis correction is performed on a continuous tone image or the one-pixel-basis correction is performed on a halftone image is switched. The one-pixel-basis correction is constantly performed on the halftone image.
