摘要： The present invention relates to a method of enlarging an image field of a camera by combining partial images. This method includes continuously rotating at least two refractive prisms such that an optical axis of the at least two prisms scans in a cycloidal pattern. Furthermore the method includes capturing a plurality of partial images. Finally, the cycloidal pattern is formed as an astroid pattern with a plurality of vertexes. The present invention further relates to an apparatus having a first refractive prism that is configured to rotate about an axis and a second refractive prism that is configured to rotate about the axis. The apparatus further includes a camera that captures a plurality of partial images. Finally, the first refractive prism and the second refractive prism form an optical axis that follows a cycloidal pattern. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

摘要： A projector in accordance with the invention includes an image processing unit that includes an image quality adjustment unit and a keystone correction unit. The image processing unit corrects the keystone error, in which a distorted image data is generated and a black part is added to the distorted image, after the image quality adjustment, such as brightness adjustment, is performed for the input digital image data. This processing order reduces or prevents the black part from being affected by the brightness adjustment and becoming a gray part, thereby enhancing the quality of the projected image.

摘要： This invention proposes to transcode the compressed image, that may be in the JPEG format for example, to an intermediate format that allows pseudo-random access. Such a pseudo-random access would that allow efficient image transformation. By using this format, in most cases a pixel is decoded only once in the entire image transformation process. This is certainly true for the most common transformation operations such as rotation by 90, 180 and 270 degrees. This transcoding would enable image transformations in printers whose memory is insufficient to store the entire decompressed image.

摘要： Morphing is performed without self-intersection in a vector space, for the outlines for various types and shapes of figures. The morphing is performed by apparatus containing an outline extractor, for receiving two target figures for the morphing process and for extracting a set of outlines for each of the target figures; an outline tree generator and an outline tree arrangement unit, for retaining one specific outline of each of the two sets of outlines and for deleting the other outlines; an outline editor, for performing a smoothing process for the two outlines for the target figures that are retained by the outline tree arrangement unit in order to prevent self-intersection during the morphing process; and a sequence generator and a morphing viewer, for performing the morphing process in response to the progress made by the smoothing process performed by the smoothing processor.

摘要： This invention suppresses a film from rising due to its curl and reduces any blur of an image generated upon projection by using a mirror image print process upon printing on an OHP film. Only when it is determined that a medium of user's choice is an OHP film, the above process is automatically applied. When a print process on an OHP film is designated, a host computer generates a print job appended with a mirror image print designation command, and transmits that print job to a printer. Upon receiving the print job, if the print job contains the mirror image print designation command, the printer converts an image designated by the print job into a mirror image, and executes a print process while feeding an OHP film.

摘要： A scanning or copying system can include imaging elements and one or more system processors that are programmed or adapted to perform image processing methods and algorithms on image data, and in some instances, to enhance the image. Image data is acquired using imaging elements. Some imaging elements may have overlapping or rotated fields of view or employ differing resolutions. For each imaging element, its output is recombined together with the output of one or more other imaging elements. To perform the recombination, the system can extract features in an overlapping region and match these features in multiple images. In some instances, the features matched can be edges. Alternatively, the recombination can be performed by positioning each subimage with respect to a larger image through image matching and location techniques. Parameters from the recombined image can be extracted and these parameters can be used to correct for geometrical and spatial distortions and thereby enhance the image.

摘要： An optimal filter kernel, formed by convolving a box filter with a filter of fixed integer width and unity area, is used to perform image resizing and reconstruction. The optimal filter has forced zeros at locations along a frequency scale corresponding to the reciprocal of the spacing of one or more pixels that comprise a source image to be resized. When a rescale value for a source image is selected, the optimal filter kernel is computed, mapped to the source image, and centered upon a location within the source image corresponding to the position of an output pixel to be generated. The number of pixels that lie underneath the optimal filter kernel is established by multiplying the number of pixels that comprise the width of the source image by the selected rescale value. Upon mapping the optimal filter kernel, the output pixel values that comprise the resized image are then evaluated by processing the one or more source image pixels, such as through interpolation. Alternatively, the output pixel values of the resized image are calculated by performing partial integral analysis with respect to a standard filter kernel of fixed width and unity area. The output pixel values are calculated by multiplying the pixel value for each pixel under the kernel by the area of the standard filter kernel surrounding the pixel. The products are then summed to reveal the output pixel value, and placed into the output image buffer. Both of these methods speed up the computation process, while producing a ripple free output image.

摘要： An apparatus and a method for correcting a distorted image is capable of correcting an optical distortion of an image and misconvergence by prewarping an inputted image without using a convergence yoke, and an image displayer using the same. The apparatus for correcting an image distortion for an image displayer in which an image signal is inputted to display an image on a screen and an image distortion is corrected, includes: a reference image generator for generating a predetermined reference image; a camera for inputting the reference image and photographing an image outputted on the screen; and a distortion information extracting unit for comparing the photographed image outputted from the camera and the reference image outputted from the reference image generator, and generating distortion correction information to correct a distortion of the photographed image in case that the image has been distorted.
