If a detected orientation of a device is turned 180 degrees from the upright direction, a three-dimensional image that can be viewed normally as a stereoscopic view can be displayed regardless of the orientation in which the device is used, by turning images that are to be viewed respectively by the left and right eyes, and inverting the arrangement of the images that are to be viewed respectively by the left and right eyes.

Image display device and image display method

This invention provides the following environment. That is, an original document file corresponding to a document to be copied is specified from image data of that document to be copied, and a print process is made based on the specified file so as to prevent deterioration of image quality. Also, when a document to be copied is not registered, a registration process is executed to suppress deterioration of image quality in an early stage. Furthermore, since the document is converted into vector data, re-use of such document is facilitated, and deterioration of image quality can be suppressed even when an image process such as enlargement or the like is made. To this end, when an original digital file cannot be specified, an apparatus of this embodiment executes a vectorization process (S), converts the obtained vector data into a data format that can be re-used by an application (S), and registers the converted file in a file server (S). With this registration process, since the location of the file is settled, that location information is composited on an image to be scanned using an identifier such as a two-dimensional barcode or the like (S), and the composite image can be printed (S). Even when the printed document is scanned again, a registered digital file can be easily specified.

Stored digital data is searched for on the basis of an input image, difference information is extracted by comparing the retrieved digital data and the input image, and the difference information is composited to the digital data. Digital data generated by composition is stored. When no digital data is retrieved, the input image is converted into vector data, and the image that has been converted into the vector data is stored as digital data. Obtained region segmentation information and an input image are composited, the composite image is displayed on an operation screen of an MFP, and a rectangular block to be vectorized is designated as a specific region from the displayed region segmentation information. A user designates the specific region by designating rectangular blocks in an image using a pointing device.

This invention provides an image processing method which allows easy re-use of image information that is stored to minimize deterioration of image quality and the storage capacity. Storage means is searched for original digital data corresponding to each input image. If no original digital data is found, the input image is converted into vector data, and is stored as digital data in the storage means. A sheet including at least one of information associated with the found original digital data when the original digital data is found in the search step and information associated with digital data which is obtained by converting the image into the vector data in the vectorization step and is stored in the storage step when no original digital data is found in the search step is generated, thus providing a sheet that allows easy re-use.

There is provided an image processing apparatus such as facsimile apparatus or digital copying machine for digitizing image data into two values or multi-values. The apparatus comprises: an input device to input data of a target pixel to be digitized; a calculating circuit to obtain an average density value of a predetermined region; a digitizing circuit such as a binarizing circuit for digitizing or binarizing the target pixel data on the basis of the average density value obtained by the calculating circuit; and a correction circuit to correct a difference which occurs upon digitization by the digitizing circuit. The calculating circuit calculates the average density value m.sub.1 of the pre-determined region when the target pixel data was binarized to 1 and the average density value m.sub.2 of the predetermined region when the target pixel data was binarized to 0 by using a predetermined weighting mask. The digitizing circuit binarizes the target pixel data by using (m.sub.1 +m.sub.2)/2 as a threshold value. When the difference between the target pixel data and the average density value is within a predetermined value, the difference is corrected, so that an image of excellent gradation can be reproduced. When it is equal to or larger than the predetermined value, the difference is not corrected, so that the resolution of a character portion such as an edge portion can be improved.
